mcosec.ai

Move a ChatGPT, Claude or Gemini chat to another AI, compacted on your device to fewer tokens. Nothing is sent to any server.

Hit a usage limit in Claude? Want a second opinion from ChatGPT? Is your Gemini chat getting long and slow? mcosec.ai moves your conversation in three clicks: 1. Open the chat and press "Read this chat". 2. mcosec.ai compacts it on your device. It keeps your goal, the latest messages, code and lists, and shortens older parts and filler. You see the token count before and after, and you can edit the result. 3. Pick ChatGPT, Claude or Gemini (or the same AI for a fresh, shorter chat). mcosec.ai opens it and places the chat in the message box. You review it and press Send. Private by design: • No account, no sign-up, no email. • No servers: the chat is read and compacted inside your browser and never sent to us. • It reads a chat only when you press the button. • No ads and no tracking. Good to know: • Files and images are not moved. Upload them again in the new chat. • Token counts are estimates (about ±15%). • If an AI site changes its page layout, reading can stop working until an update. You can always paste the chat yourself. See your own usage in Settings: chats moved and tokens saved, counted only on your device. Extra tools (turn on in Settings): a prompt library, an on-device prompt optimizer and AI-written handoff requests.
