AI Limit Meter + Chat Handoff by ReadyStack

One meter for ChatGPT, Claude and Gemini — with the exact time each limit comes back. And when you hit the wall in the middle of a long chat, carry that chat to another AI with every code block word for word.

Free:
- Limits of all three AIs in one popup, a toolbar badge and a small meter on the chat page (you can hide it)
- Claude: your 5-hour, weekly and per-model use, straight from claude.ai's own usage numbers
- ChatGPT: Codex 5-hour and weekly windows when your plan has them, plus your messages counted against the cap you set (Free and Plus presets)
- Gemini: your messages counted against the cap you set
- Any "limit reached" message is read for its reset time (English, German, Spanish, Portuguese, Japanese)
- Copy a handoff of the last 20 messages with code blocks kept, or save the whole chat as Markdown

Pro ($3.99 a month or $29 a year, paid on our website):
- Whole-chat handoff fitted to the size you pick: what you set out to do, every request you made, the latest version of each code block, the last messages word for word
- One click opens a new ChatGPT, Claude or Gemini chat with the message box filled. You read it and press Send; nothing is sent for you
- Alerts at 80% and 95% and when a limit is back
- Pace forecast: "at this pace you hit the limit around 9:40 PM"

Why it is different:
- Three AIs in one place, not claude.ai only
- The handoff is shortened inside your browser; no AI call and no API key of your own needed
- No account, no sign-in, no server. The only request to us is the licence check when you type a key
- Interface in English, Deutsch, Español, Português and 日本語; the handoff note is written in the language of your chat
