> It has an effective context window of 2M tokens, and can index projects of 20M tokens and beyond using tree-sitter project maps (30+ languages are supported). It can effectively find relevant context in massive million-line projects like SQLite, Redis, and Git.

Does this possibly have non-coding-related utility for general reasoning about large volumes of text?

The project map supports markdown files (and html), so you could definitely use it to explore docs, notes, etc. if they're all in markdown/html. Plaintext files aren't currently mapped though, so just the file name would be used to determine whether to load those.
