Thread is an AI journal and second brain for capturing thoughts, ideas, notes, and voice recordings. It automatically connects related memories, finds patterns in your thinking, and turns scattered ideas into meaningful threads. Capture anything in seconds, rediscover what matters, and turn your thoughts into actionable ideas with a private AI-powered memory system.

Hey Product Hunt 👋 I built Thread because I kept having useful ideas throughout the day, then losing the context around them. Thread lets you capture thoughts by text or voice, then uses AI to connect related ideas and memories over time. Instead of leaving everything as isolated notes, it helps turn scattered thinking into meaningful threads you can revisit and act on. I’d love your feedback on what feels useful, what feels unnecessary, and what you’d want Thread to do next.

An AI journal that connects thoughts instead of just summarizing them is the right ambition. This could become a real thinking companion. Congrats.

 Thank you for your encouraging words.

journal content is about as sensitive as personal data gets, more so than most notes apps since people write things there they wouldn't put anywhere else. when you say "private AI-powered memory system," does the connecting/pattern-finding happen on-device, or does journal text get sent to a server (yours or a model provider's) to do that linking?

 The connection still happens on server but this isn't marketed for your day to day journal. This would actually help you formulate your ideas. for example you are thinking about. a product or app feature in the morning but by the time you start working you may forget the idea. The app tries to help in those scenarios. It will keep those idea connect them together and form proper threads to follow.

 appreciate the straight answer. that's the part I'd want spelled out on the landing page itself, not just in a comment thread - is journal content encrypted at rest and in transit, and is it ever used to train or fine-tune anything beyond your own account's connections?
