Stashwise is the second brain your AI can actually use. You already collect the good stuff: articles, videos, posts, ideas, tutorials, research, tools. But it piles up, disappears into folders, and goes missing the moment you need it. Worse, none of it is available to the AI tools you work in every day. Stashwise fixes both. Save a link, video, or note, and it pulls out the useful parts for you: summaries, key takeaways, topics, connections, and learning paths. Everything you keep becomes a structured, searchable personal wiki. Then it goes further than a notes app ever could. Connect your AI tools, and they can read and search everything you have saved, right inside your own workflow. You choose what goes in, so your assistant is grounded in sources you actually trust instead of whatever the open web returns. You are building the knowledge, and putting your AI to work on it. Collect what matters. Your AI uses it anywhere you want. - What you can do: - Give your AI your knowledge Connect Stashwise to your AI tools so they can draw on your saved library while you work, grounded in what you collected, not random web results. - Search your own collection Ask questions and get answers from the things you saved, not the open web. - Chat with your saves Understand articles, compare ideas, pull out details, and make sense of a messy collection. - Create Learn Guides Turn saved material into structured learning paths built from resources you already found interesting. - Analyze videos Save supported videos and clips so they become searchable, summarized, and easy to revisit. - Build a personal wiki automatically Stashwise extracts topics, summaries, and relationships without making you tag everything by hand. - Catch relevant trends See emerging topics that connect back to your saved knowledge, so new ideas are easier to place. - Own your knowledge Your wiki is never locked in. Export to Markdown or Obsidian, keep a local backup, or bring your saved context into your own workflows. Your notes, your wiki, and your AI should all be able to use the knowledge you already collected. - Who it is for Stashwise is for builders, students, researchers, creators, and curious people who save more than they can process. If your bookmarks, notes, and watch lists are a pile you meant to come back to, Stashwise turns that pile into knowledge you and your AI can actually use. Collect the knowledge. Put your AI to work on it. Grow a brain you own. Terms of Use (EULA): https://stashwise.co/terms Privacy Policy: https://stashwise.co/privacy
