About Skillsync

Skillsync makes your agent session history searchable. Both for you and your coding agents. It searches all your sessions before each prompt and hands your agent what you already figured out. It gives you one place for everything your agents have ever done. Move a full session between Claude Code, Cursor, Codex, and any other agent with nothing lost, including the entire conversation, the model's reasoning, and every tool call, not just a summary, so the next agent picks up like it was there the whole time. Skillsync is local-first and yours, and its core engine, txcript, is open source, a portable session format that no single provider owns.
