## What is MetaList?
MetaList is a personal knowledge management web application, 
tightly integrated with large language models.

> ⚠️ **MetaList is currently in Development**: Expect breaking changes and bugs

## Features

- [x] Chat feature: LLM integration (currently only [OpenAI API](https://openai.com/blog/openai-api))
- [x] [Chart.js](https://www.chartjs.org/) integration for LLM-generated visualizations
- [x] Hierarchical, collapsable note structure
- [x] Reordering notes in one context survives to other search contexts; notes maintain a [total order](https://en.wikipedia.org/wiki/Total_order)
- [x] Quick, responsive searching (tags, full-text, or combo of both)
- [x] Search suggestions
- [x] Tagging
- [x] Tag suggestions (uses a [Jaccard index](https://en.wikipedia.org/wiki/Jaccard_index))
- [x] Tags can imply other tags
- [x] Tag implication rules are also notes; they can themselves be tagged and searched
- [x] Nested subitems in notes inherit tags from their parents
- [x] [Markdown](https://markdown-it.github.io/)/[LaTeX](https://katex.org/) support
- [x] Infinite undo/redo
- [x] Infinite scrolling

###  Chat Feature

Search filters notes down to a relevant subset (a "search context"), which has the nice 
effect of acting as a form of human-guided [retrieval augmented generation](https://www.promptingguide.ai/techniques/rag).
The chat feature is fully integrated with the underlying notes. Mousing over a reference in the chat will highlight 
the referenced note, if it is within view, and clicking on the reference will navigate to and select the note, 
even opening up collapsed items in the note hierarchy so that all the relevant info becomes visible.

#### Some Examples

Recommendations based on a list of favorite movies,
