Notes, research, and past conversations stay connected, so you never start from zero.
Free forever. No credit card.It has no idea who you are, what you're working on, or what you already know.
You compensate by re-pasting context, re-explaining decisions, re-summarizing research — every single session. That overhead compounds. Multiply it by every chat you open.
ChatGPT remembers, but only in ChatGPT. Claude knows your project, but only in Claude. Every platform locks your context in — by design.
Atropy is where your context lives — outside any one tool, available across all of them. Write a note once. Bring it to any model, any time.
Notes, past conversations, and research — connected to every session. Any model. Nothing resets.
Not a summary. Not a snippet. The full document. Add multiple notes and past conversations at once. The model works with everything you give it.
Claude for strategy. GPT-4o for drafts. Gemini for research. Switch between them freely. Your notes and conversation history stay exactly where they are.
One click turns a long thread into a structured note — decisions made, questions still open, what to do next. That note becomes context for the next session. Nothing gets lost.
Fork the conversation to explore a different direction without losing where you were. All branches share the same notes. Go back, go forward — nothing is ever deleted.
Every conversation you've had is available to bring into a new one. Drag an old thread in and the AI picks up exactly where you left off — across weeks, across models.
50 requests a month, free forever. Pro gives you the best models, unlimited fast usage, and 500 premium requests monthly.
