The smallest Flinch. A decision model that runs on your own device, right in the browser tab or on a phone.
Before your AI app spends a single token, Flinch Nano answers the questions that decide what happens next:
- Is this an attack? Hidden instructions, jailbreaks, prompt extraction, caught before they reach your model.
- What does the person want? Code, writing, maths, facts, translation, a summary, a chat, an image.
- Which model should answer? No model, a small one, or a big one.
- What personal data is in here? Found and masked before anything leaves.
No per-call bill, no round trip, nothing sent anywhere to make the decision.
