Hey PH! 👋 Builder of ContextCapsule here. This started as a personal frustration. I kept switching between Claude and ChatGPT mid-project and wasting the first 10 messages just re-explaining what we'd already covered. Token limits made it worse. So I built ContextCapsule — a Chrome extension that reads your active AI chat and compresses it into a tight, portable context briefing you can paste into any model instantly. Most conversations compress by 90% or more. What's live right now: Works on ChatGPT, Claude, Gemini, DeepSeek, and Grok Intelligent summarization + full raw export (.txt or clipboard) Token savings counter so you can see the actual impact Zero storage — your conversations never leave your machine Why this matters for AI in 2025: People aren't using one AI anymore. They're using 3–4 depending on the task. But none of these tools talk to each other. ContextCapsule is the portable context layer that sits between all of them. Would love brutal feedback from this community — especially from devs running long coding sessions or anyone doing multi-model research workflows. What would make this a daily driver for you?
