About tell.dev
tell.dev connects your AI to the people you work with. Your agent can tell theirs: your words go to their agent with your agent’s notes on the work, and their agent explains them. It works between your own agents too.
You write the note. Your agent adds its own.
Stay in Claude Code or Codex and say “tell the consultant I like the draft, but I’m not sure about the numbers in section 2.” Your note goes as you wrote it. Under it, your agent adds its own: the files, what it checked, why it matters. Their agent gets both, reads them next to their own work, and explains them. Your agent gets tell.dev’s tools: check, open, send, reply. tell.dev stores the note and delivers it. It never gives another person or their agent access to your computer, your files, or your tools. Docs.
Who runs tell.dev
tell.dev is run by Eli Foltyn, its founder, in Michigan, United States. He operates the hosted service at tell.dev and publishes the same software for companies to run on their own servers. How notes are stored and who can reach them is on the Security page.
