AI Token Saver

Save tokens on long Claude and ChatGPT chats. Summarizes the conversation and continues it in a fresh chat with one click.

Long AI chats get expensive. Every new message re-sends the entire conversation, so each reply uses more of your usage limit, gets slower, and the model starts losing track of early details. AI Token Saver fixes that with one click. When a chat on claude.ai or chatgpt.com gets long, it: 1. Shows a small card with the chat's current size. 2. Asks that chat for a handoff summary: your goal, decisions, key facts, latest code and next steps. 3. Opens a new chat on the same site and sends the summary there. You carry on where you left off, and every message after that re-sends a short summary instead of the whole history. Your old chat stays in your history. What it saves In our tests on long chats (45–50k tokens), handing off at the default 20,000-token threshold cut total tokens processed by 36–44%, including the cost of writing and sending the summary. A fresh model reading only the summary answered 96% of questions about the earlier chat correctly. Features - Automatic alert when a chat passes your threshold (default 20,000 tokens) - One-click summarize and continue, with the summary sent for you - Toolbar popup showing the current chat's size, with a button to hand off early - "Later" and "Not for this chat" options on the alert - Adjustable threshold, auto-send and summary prompt in Options - Anything you had typed but not sent comes along to the new chat Private by design No servers, no accounts, no analytics, no tracking. The extension reads the chat page only to measure it, and only sends messages inside the chat you already have open. Settings stay in your browser. Good to know - The token count is an estimate from the visible text; files and images aren't counted. - Summaries keep what you need to continue, not every detail. For exact long code, paste it again in the new chat. AI Token Saver is an independent extension. It is not affiliated with, endorsed by or sponsored by Anthropic or OpenAI.
