Git-native project memory that just makes sense.

Jellybook is a lightweight, Git-native workspace for managing
the knowledge and workflow around a software project.
Issues, changes, reviews, docs, and project memory belong
with the code as readable, versioned project data.

Portable by default

All project data is plain text and versioned
in your repository. Easy to move, easy to
back up, easy to trust.

Built for humans and agents

Clear structure for issues, discussions,
docs, and decisions—designed for
teams and AI tools alike.

Repository as source of truth

Your repo is the single source of truth.
Jellybook keeps every update
connected to the code.
