AI Context Portとは
Stop repeating yourself. Continue AI chat across ChatGPT, Claude, Gemini & more in one click — without losing your AI memory. Hit an AI limit mid-conversation? Context Port transfers context to any AI chatbot in one click.
You're 40 messages deep. The code is finally working. The idea is finally clicking. Then the ai limit hits. "You've reached your limit." You open a new conversational ai assistant. Stare at the blank input. And start typing the same backstory you've already typed a dozen times this week. Context Port fixes this.
HOW IT WORKS
Context Port runs quietly in the background while you work on any major artificial intelligence chat tool. The moment you hit a usage limit, it appears. Offering to continue your conversation on any other ai assistant in one click.
Your full context transfers automatically. The new AI chat picks up exactly where you left off. No copy-pasting. No re-explaining. No starting over.
Hit your ChatGPT message limit? Continue on Claude. Hit your Claude limit? Switch to Gemini. Context Port doesn't care which platform you use, it just makes sure you never lose your thread.

FEATURES
◆ Instant transfer - automatically detects usage limits and shows a one-click transfer panel so you can continue your conversation without interruption
◆ Smart context transfer - doesn't just copy and paste messages. Highlights your key decisions, what's already been tried, and the most important exchanges so the new AI assistant understands immediately
◆ Auto-paste on arrival - open the new AI chatbot and your full context is already waiting in the input field, ready to send
◆ Context profile - save who you are, your stack and your preferences once, and it's added to the top of every transfer. Never re-introduce yourself to a new AI again
◆ Save and search your conversations - bookmark any chat locally and search across everything you've saved, by title, model or anything said inside it
◆ Ai chat exporter - download any conversation as plain text, or export to Markdown and JSON for Obsidian, Notion and AI projects
◆ Manual transfer anytime - move to any major platform at any time, not just when you hit a limit. Great for comparing responses or choosing the best model for each part of your task
◆ Edit before you transfer - review the context summary, pick which messages go across, and fine-tune exactly what the new AI chatbot receives
◆ Live token counter - an estimated token count sits quietly on every page, so you can see at a glance how large your conversation has grown
