About the startup
Your agent writes the code, then the conversation ends and you review it alone. Diffo keeps it open: a live diff in your browser. Comment on a line and the session that wrote it answers, and its fix lands in the diff you're reading. Big changes come in layers, in the order to read them. Works on GitHub PRs too: the agent drafts comments, you submit. Not an AI reviewer: no grades, no nitpicks. Works with Claude Code, Cursor, Codex. Local, no account, Apache-2.0. Try it: diffo.io/demo
