# bitmark Documentation

Meet bitmark: the open, AI-native format for knowledge

Knowledge as semantic chunks: typed, addressable bits, linked into a graph, that people and AI read the same way.

## Start

- [Why bitmark](https://docs.bitmark-association.org/concepts/why-bitmark.md): bitmark is the open knowledge format.
- [Getting started](https://docs.bitmark-association.org/concepts/getting-started.md): Three steps take you from a first bit to JSONL: try it in the playground, convert it on the command line, then use the parser in your own code.
- [The parser](https://docs.bitmark-association.org/concepts/parser.md): The bitmark parser is the reference implementation of bitmark.
