The memory you own.

Knowledgebooks are a plain-words record of what you choose to keep, that only changes when you say so. Every line shows where it came from, and you can edit or remove any of it. They're live on the web today, on every plan, with iPhone and Android coming soon. The three Experts (Researcher, Writer, and Lookout) are live too.

For most conversations, it doesn't need to, and that's the point. About 80% of what people ask AI are one-off questions. For the things that matter, you choose what to keep in a Knowledgebook: your dietary needs, your kids' names, your work context. You see everything and edit anything. Later, in late 2026, your Knowledgebooks can travel to other assistants you choose.

When the AI uses web search, it includes citations directly in the response. You can see which sources informed which parts of the answer and click through to verify. Below the response, you'll also see which AI model was used and whether search was involved.

Your chats auto-delete by default, so there's little to lose there. You can export every Knowledgebook today, free on every plan. We've built the product so you're never locked in.

Yes. Choose a default auto-delete window of 8 hours, 7 days, or 30 days in settings. 8 hours remains the default. Every chat shows its own countdown so you always know exactly when it clears, and you can still extend or delete any individual chat whenever you want. Change your window anytime.

The free Essential tier is genuinely free with no hidden data collection. You get unlimited AI chat, automatic web search, auto-deleting chats, and cross-device sync. Lookout is free and unlimited: check any scam, phishing text, or robocall before you act. You also get About You, your first Knowledgebook, plus three custom Knowledgebooks, and one free run each of Researcher, Writer, Deep Research, a voice conversation, and an upload. It handles about 80% of what most people use AI for, and it's funded by the paid Expert tier.
