Prompt Relay

About

Never lose context again.

Prompt Relay helps you stay in control of your AI conversations. It tracks how much of each assistant’s context window you’ve used, warns you before you hit the limit, and lets you hand off a conversation to another AI without starting from scratch.

Works on the sites you already use ChatGPT, Claude, Gemini, Grok, and Perplexity — no account or signup required beyond installing the extension.

See usage at a glance A compact overlay on each supported site shows:

Context usage — how full the current conversation is
Daily usage — tokens used today vs your configurable limit

Warnings before it’s too late Get proactive alerts at 80%, 90%, and 95% context usage so you can wrap up, summarize, or relay before the assistant starts forgetting earlier messages.

Relay conversations between AIs When you’re running out of room — or want a fresh perspective — Prompt Relay compresses your conversation into a structured handoff and opens your chosen destination assistant with the context ready to continue.
