Prompt Bridge is the free Chrome extension that carries your full AI conversation context across all major AI platforms — never restart a thread again.
Hey hunters 👋
I use ChatGPT to draft, Claude to think, Gemini to search, Grok to get roasted. And every single switch started the same way:
"So, context: I'm working on…" → paste 40 messages → wait → do it all again tomorrow.
I was spending more time re-explaining myself to AIs than doing the actual work. So I built the thing I kept wishing existed 🌉
⚡ THREE CLICKS, NO RE-EXPLAINING
🎯 Capture — grab your full thread from ChatGPT, Claude, Gemini, Grok or DeepSeek
🗜️ Compress — squeeze it into a tight context pack (12,400 tokens → 890 in my last test), so the next AI gets the signal, not the transcript
🌉 Bridge — drop it straight into the other AI's input box. Switch tabs and it auto-detects where you landed. Zero setup.
🔒 THE PART I'M STUBBORN ABOUT
It never leaves your machine. Threads live in your browser's IndexedDB. Provider keys are AES-256-GCM encrypted locally. I run zero servers — there is physically nowhere for your conversations to go. No telemetry, no analytics, no account, no email wall.
Don't take my word for it. Open DevTools → Network and watch it stay empty 🕵️
💸 FREE, WITH ONE HONEST ASTERISK
Capture and Bridge cost nothing, forever. Summarising runs on your own provider key (OpenAI, Anthropic, Google, DeepSeek, xAI) and talks to them directly — never through me. Your key, your bill, your data.
It's the only setup where "we never see your conversations" is literally true instead of a marketing line.

🙏 ONE THING I'D LOVE FROM YOU
Which two AIs do you bounce between most? Genuinely asking — that ordering decides what I optimise next. And if the compression ever eats something it shouldn't, tell me right here. That's the feedback I need most today.
