Show HN: Hivinq – Copilot for customer support teams
by vishalds | 2026-01-13 16:04:57+00:00
A lot of teams are hesitant to adopt AI customer service bots due to their inauthenticity in replies, hallucination, etc. As a result, they're not able to leverage the speed of LLM's to reduce their customer turnaround time. So instead of replying to the customer directly, Hivinq drafts responses for the customer support team using it's knowledge about the product. If the drafted answers are inaccurate, team members can let it know and it will observe the thread to learn and correct itself.

Show HN: Verdic Guard – Deterministic guardrails to prevent LLM hallucinations
by kundan_s__r | 2026-01-13 16:05:02+00:00
I’ve been working on Verdic Guard, a validation layer for production LLM systems where prompts, filters, and monitoring aren’t enough.

In many real deployments (fintech, enterprise workflows, agentic systems), the failure mode isn’t latency or cost — it’s hallucinations that sound confident and pass surface checks. Prompt engineering helps, but it doesn’t scale once systems grow long-running, tool-using, or multi-agent.

Verdic takes a different approach:

Define an explicit intent + scope contract for what the model is allowed to output

Validate LLM outputs before execution, not just inputs

Block or flag responses that drift semantically, contextually, or domain-wise

Keep enforcement deterministic and auditable (not “best effort” prompts)

It’s designed to sit between the LLM and your application, acting as a guardrail rather than another model.

This is still early, and I’m especially interested in feedback on:

Where this breaks down in real systems

How teams currently handle hallucinations beyond prompts

Whether deterministic enforcement is useful or too restrictive in practice

Happy to answer questions or share implementation details if useful.
Show HN: Kalshi Market Intelligence and AI Signal Analyst
by founder_mode | 2026-01-13 16:05:03+00:00
Hi HN,

I built a lightweight market intelligence layer for Kalshi prediction markets.

Instead of scraping pages, it intercepts Kalshi’s APIs to track:
• Stateful volume trends (rising / falling)
• Liquidity depth
• Basic sentiment signals

It also includes a BYOK AI adapter so users can generate short trader briefs using their own LLM key (ChatGPT, Claude, Gemini, etc.). Designed to run on very low resources (fits Apify’s 1GB free tier).

I built this as part of the Apify $1M Challenge and would love feedback from people interested in prediction markets, market microstructure, or quant-style tooling.

Looking at the article's graphs - both the deaths and the increase in deaths are very strongly skewed toward the highest age brackets. Deaths fell in the 34-and-under brackets.

Are 85+ folks falling more (or worse), because they're paying more attention to their phones than to their feet? Or maybe the fatal falls are caused by collisions with nose-in-phone kids?

There are 3 Precogs in the film, but in reality the female one is the most powerful and the twins seem to only function as amplifiers. It's revealed that there is sometimes/often a disagreement between their visions and that they do a 2/3 selection or something like that and discard the disagreeing vision (the 'minority report'). I believe this is what happened to the main character when he is framed, the stronger female's dissenting vision is ignored in favor of the two amplifiers. In the film it is ambiguous if he even commits the murder at all, the guy he kills was paid to die and more or less forces him to kill him in the struggle.

There's also the echos of visions that occur which is how the villain manages to get away with a murder, he uses his inside knowledge to copy cat another murder method which allows him to have it written off as an echo.

The wilder question in the movie is how the precogs are randomly created mutations in response to the mother taking a weird street drug during pregnancy. They'd have to dose pregnant women and hope they gave birth to more mutants if they ever want to replace the set they have, and I believe they're planning to roll it out nationwide. But given how crappy the precogs' lives seem to be maybe that is just a cost they consider worth paying.

git rebase appears to be a random number generator to me. I've got two PRs in flight, I realize that one branch requires something I did in the other branch. I go merge branch one, then rebase branch two off main. Half the time; success, get on with my day. The other half of the time; anarchy, madness, dogs and cats living together.

I remain terrified.

ISTM that improving one's emotional self-regulation is an excellent first-line response to being in what seems to be a toxic job. It may be that leaving that job and applying for another is still the right thing to do, all things considered, but we cannot know for sure unless we are in that situation ourselves and can de-stress enough to do a proper evaluation of it.
by embedding-shape | 2026-01-13 16:06:11+00:00
But yeah, that's reddit, people/bots rejoice over anything being cargoculted there, and you really can't take any upvote/downvote numbers on reddit seriously, it's all manipulated today.

Don't read stuff on reddit and use whatever you've "learned" there elsewhere, because it's basically run by moderators who try to profit of their communities these days, hardly any humans left on the subreddits.

Edit: I really can't stress this enough, don't use upvotes/likes/stars/whatever as an indicator that a person on the internet is right and has a good point, especially not on reddit but I would advice people to not do so on HN either, or any other place. But again, especially on reddit, the upvotes literally count for nothing. Don't pick up advice based on upvoted comments on reddit!

It's funny because while I believe the concept of toxic masculinity is absolutely badly used in general, and should be seen with suspicion, here is one of the real examples it makes sense to use it. There absolutely people (Andrew rate is one of the most famous) that prey on the weaknesses and toxic aspects of masculinity (you have also the same for female weaknesses and toxicity)

Hardware? The real world? Pretty much everything?

Power. Real power. The power to kill you, take your property, harm your family, tell lies about you on the news, etc.

I've always been surprised by the naivety of tech people with respect to this question. The only possible solution to power is power itself. Software can be a small part of that, but the main part of it is human organization: credible power to be used against other organized holders of power. No amount of technology will let you go it alone safely. At best, you may hope to hide away from power with the expectation that its abuse will just skip over you. That is the best you could hope for if all you want are software solutions.

Again it's a supply chain problem. Regardless of how much cash you have, you can't just order a new battery factory or nuclear power plant and have it up and producing in a couple years. We have eviscerated our supply chains for those things and no matter how much money we throw at the problem now it's going to take decades to reindustrialize. Rome wasn't built in a day.

If the concern is over externalities such as CO2 emissions and other types of pollution then sure, let's tax those directly. That will help accelerate solutions through free market mechanisms.
Show HN: Aristotle, an AI-powered e-reader that helps you read deeper
by smahendrakar | 2026-01-13 16:06:32+00:00
We started building Aristotle after noticing a pattern with a lot of AI tools: they’re great at replacing work, but not always great at helping people grow, especially when it comes to reading and learning.

With reading in particular, so many tools optimize for shortcuts: summaries, takeaways, skipping the hard parts. We wanted to explore a different direction: how AI could make reading more engaging, accessible, and enjoyable without replacing the experience itself.

Aristotle is an in-browser e-reader that supports PDFs + EPUBs, with features like spoiler-free chat, quick explanations, contextual insights, AI-generated illustrations, and speed reading tools to help readers stay immersed and get more out of what they’re reading.

Trying to pick a good name for the keyword is valid but it's bikeshedding. Either way the keywords should be consistent and a config option is more trouble than it's worth.

And "variables" in math are almost always immutable within a single invocation. It's not a particularly bad word to use. But there's plenty of options. const/var. let/var. let/mut. var/mut I guess. let/set from a sibling comment.

Why the negativity? If you don't want to use it - dont use it.. I think it's amazing especially for people who are not yet familiar with RSS Feeds, this is a great starting point. Maybe add a Best 10 feed, having Gruber in the Top 25 already pull a lot of posts. But either way great work mate, Make RSS Great Again!!

Yes, exactly what I've been thinking about. I remember a conversation I had here a few years back where a few of us were sharing how growing up on forums like 4chan had implanted in us a deep nihilism and cynicism, and how that was being mistaken for stoicism, when really it's just being emotionally stunted.

I've been thinking about this modern idea of stoicism along the same lines you've written here. Basically it seems like a lot of self help is directed towards this idea of regulating and controlling yourself, often by trying to overcome our inherent flaws as humans, which I don't necessarily disagree with. However, take for example this from the article:

> has given the name ‘negative visualisation’. By keeping the very worst that can happen in our heads constantly, the Stoics tell us, we immunise ourselves from the dangers of too much so-called ‘positive thinking’, a product of the mind that believes a realistic accounting of the world can lead only to despair. Only by envisioning the bad can we truly appreciate the good; gratitude does not arrive when we take things for granted.

This is fighting an uphill battle. Rather than work against our own psychology, it seems to me that the better thing to do is to leverage our irrationality to great affect, which is what positive thinking and self actualization does. "Fake it til you make it" genuinely does work.

I'm starting to feel like the better path to take is the one that fully acknowledges and embraces all of our sloppiness. I've been doing this with my ADHD: rather than trying to leverage system upon system to normalize my behavior, I've tried giving up on that entirely and instead focusing more on directing things like hyperfocus in productive directions. I've been trying to put aside this lie I've been telling myself that I can be some strong independent man forging his own path, and spending lots of time with people, asking people lots of questions instead of going home to read on my own. Rather than try to master my willpower when it came to weight loss, I accepted my weakness and threw away all the snacks in the house.

I think stoicism still has its place in attempting to prevent e.g. self harming behavior in response to e.g. anger or depression (blowing up on someone for example), but I feel lately like it's a pointless lie to pretend we can go through life without letting other people affect our emotions; or if not a lie, then that to try to do so cuts us off from an absolutely critical aspect of human existence.
Show HN: A workflow for publishing AI-assisted content without manual rewrites
by PlagiarismRem | 2026-01-13 16:06:59+00:00
We publish a lot of AI-assisted content.
Manual rewrites were killing productivity.

This is the workflow we ended up with:
1. Draft with AI
2. Structural normalization
3. Semantic preservation pass
4. Final human skim

It reduced rewrite time by ~80%.

I have a two famous friends in the television industry. It seems they fall into the trap that since they produce popular TV shows that they then can think they know every thing about everything else, mostly because of the people that surround them want to stay friends so they can be associated with the fame. I think this is the trap Adams fell into as well. Whether that was with his knowledge or ignorance I do not know.

I do not let my friends get away with them thinking they are experts on everything.

Adams turned his fame of Dilbert into his fame for saying things online. I mean he even started a food company! Anyone remember the "Dilberito"??? Seems he was always just looking for more ways to make money. And reading his books it sounded like he wanted to get rid of religions.

So he was human, just like the rest of us. And he died desperate and clutching to life, leveraging whatever power he had to try to save it from who ever he could.

It's a pity Apple didn't choose to acquire Affinity when there was a chance. Pixelmator Pro looks like a toy app compared to Logic or Final Cut. I don't see how it could ever catch up to Photoshop. Even at such small scale it's always been very buggy in my experience and development seems to have stalled (apart from some obligatory AI features).

I am glad the standalone purchases are still available and I assume they will stay updated in sync with the subscription-based ones. I would hate my copy of Logic getting slowly obsolete..

I set up my kid, I think she was 3 or so, she started out with stamps of butterflies and the like. After awhile she looked at her hand, then mouse, then me, stared at me and said "ouch". I got a "travel" mouse that was half size or so, perfect for her hand and she loved using tux paint.

Don't forget to setup sound, preferably in stereo.

She used the hell out of it for years. One time on a call she was fascinated by fish. I printed out one of her drawings remotely while we were on the phone and she loved it.

Had this in the back of my mind for a while now, too. In terms of prior art, Keybase had been doing something similar, but with Merkle trees.

Could you tell in a bit more detail why you decided to go with your own DSL here? :)

If they are accused of crimes, then arresting people is not just a power but a mandate. If they just so happen to be his political enemies, that does not make them exempt.

If he happens to be dumb enough to say "Arrest Chuck Schumer without charge because I don't like him", then maybe the court might see that as outside his powers. But he has been accusing his political enemies of crimes for years; he'd only have to pick one of them and have them arrested for it.

We don't make Presidents justify their actions as core powers. If we believe that he ordered an unjustifiable arrest, the burden of proof would be on us.

Merging a PR with rebase doesn't lose provenance. You can just keep all the commits in the PR branch. But even if you squash the branch into a single commit and merge (which these tools automate and many people do), it still doesn't lose provenance. The provenance is the PR itself. The PR is connected to a work item in the ticketing system. The git history preserves all the relevant info.

Is there a reasonable migration path to help your customer move to another solution? If so, you could shut it down gracefully without giving pain to your people.

Because unless you just don't care about your customers, thinking about the best answer for them is often a good guide. If you don't want to run it anymore, do you think someone else can just pick it up on the fly? FYI, In my experience, that answer is always "No", because SaaS apps are about knowing the problem space, the customer needs, and the history. Being able to read the code is 5% of the work. So people tend to quickly be willing to try, but then get discouraged when they realize the difficulties and just shut down on the customers anyway.

So I'd recommend that if you don't want to run it, but also don't want to just turn it off, find a small group of people who know your niche/market, and who already run a SaaS, and pass it on to them. Often, competitors will turn into partners in such situations. Sometimes that even works best for everyone - you get to escape, your competitors grow a bit, and the customers are taken care of.

That is a lot of rambling, but the overall point is that there are probably more options out there than just sell/quit/keep going.

This is an interesting subject because it is so poorly studied. Extreme calmness could also be called hypo-neuroticism. Hyper-neuroticism is extremely well studied because there are performance consequences to high anxiety and physiological consequences to extreme anxiety.

The most extreme lowest of neuroticism is generally guessed at lesions in the brain that prevent the formation of fear memories from the amygdala. Lesser extreme low neuroticism is possible from conditioning due to repeated participation in high stress situations. This is typically confined to emergency medical technicians/doctors, deployed military, and certain law enforcement officials. For example, combat medics are 4 times more likely to develop PTSD from a combat encounter than their infantry peers, because the stresses are equal but the impact from performance failure is not equal.

Low fear personalities have fewer restrictions on their decision making capacity. That loss of inhibition can be both good and bad. This is why ethics are so profoundly and critically important to the culture of the US military because a culture of rules serves to both replace the natural limits of chaotic actions and simultaneously serve as a framework to enable more predictable output.

I once interviewed for a tech job at the Seattle times. I didn't land the job, but the interview was enlightening. I was told that the investigative reporters at the newspaper did all of the "work" of uncovering news. Subsequently, the TV broadcast station would just report on what the newspaper found. Meanwhile, the broadcast news was raking in tons more ad revenue than the newspaper.

Ever since then, I've often brainstormed of ways to remove all of the layers between the actual investigative reporter and the general public looking for a way to get as much of the revenue directly from the public into the hands of those doing to investigations and reports.

I've had ideas though nothing revolutionary enough to share here. Still, I think the overall goal would be good for literally everyone.
by mrweasel | 2026-01-13 16:09:30+00:00
In some sense I agree, there is a level of defeatism in at least part of the wisdom of the stoics and very little questioning of authority. You do have the "If it's not right don't do it, if it's not true don't say it", and you are suppose to act on things if they are within your control. There's just no encouragement that you're more capable than you think or that you should do anything beyond "The best revenge is to be unlike him who performed the injury." That doesn't really topple oppressive regimes.

It's a bit of a interesting take, you should act with virtue, but there is no encouragement to act against oppression and question authority. It seems very much like something to ignore and hope there's not a clash.

This is the real issue. FOSS was born out of a utopian era in 60's-2000s' where the US was still a beacon of hope. That is fundamentally impossible in todays world of ultra-shark-world-eat-you capitalism and global race to the bottom.

Nice work. I started around same time as you 1996. I was selling professional dj software as shareware called ClubDJ Pro from 1999-2012 before coding for the app store as well.

Impressive that you have created one app and stayed focused this whole time. I ended up creating multiple apps and having a couple acquired and moved on to other projects, but maybe I have ADHD lol.

I like your website, but I did find two dead links to the appstore here https://primoco.me/en/apps

These links do not work. I believe you want /us/ not /en/ for the links

Battery prices are getting really low, if you're willing to do some DIY. Just received a 15kWh battery from China. A 'Humsienk'. Combined it with a GroWatt SPA3000TL-BL inverter.

Total price, 1600 euros. So close to the magical 100 euros per kWh. Driving it with some interesting combinations of Raspberry PI's and serial interfaces and custom written Go code, but it works... :)

> It's a pretty nice best-of-both-worlds arrangement

It’s also a worst-of-both-worlds arrangement, in that you have to do the extra work to satisfy the type checker but don’t get the benefits of a compiled language in terms of performance and ease-of-deployment, and only partial benefits in terms of correctness (because the type system is unsound).

AFAIK the Dart team felt this way about optional typing in Dart 1.x, which is why they changed to sound static typing for Dart 2.
