Sidekick is designed for the ultimate online work experience and brings together every web tool you use. Today, anyone who works in a browser fights to stay organized. Tabs are out of control, browser windows are all over the place, and desktop apps may work on their own, but they donโ€™t integrate well with the rest of your work on the web.

Sidekick changes all of that.

ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity โ€” no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

    So many bugs to fix

    The idea of a productivity based browser is great but since this browser is still new, it has trouble with a lot of things. Sometimes it doesn't open a new tab when i try, sometimes web apps don't open, and overall its not a smooth experience that i could recommend to people
