Skillsync, founded by Nars and Nishant, lets you move AI chats across every coding agent. Most work exists as conversations scattered across agents in different formats, locking you into a single provider. Skillsync acts as a universal converter, moving entire sessions including messages, reasoning, and tool calls so you can pick up where you left off.

The core is an open-source Rust engine called txcript, which translates sessions between agents' on-disk formats — think ffmpeg or pandoc for agent sessions. A local-first desktop app surfaces scattered sessions in one readable place. Skills and memory are stored as portable markdown you own, exposed to any agent over MCP.

Everything runs locally except what you explicitly share into team workspaces. People use Skillsync to move sessions between Claude Code, Codex, and Cursor mid-task, hand browser chats to coding agents, and share research sessions across teams.

Before Skillsync, Nars and Nishant built an open-source payment orchestrator with 30k+ GitHub stars fighting vendor lock-in. They see the same problem with coding agents: your context is locked into whatever agent you start with. It's available as a Mac app, CLI and MCP.
