Second Brain allows you to AI chat with anything on a Visual Board — you can drop as much context and chat nodes as you want. Over time, you build a knowledge base — everything is interconnected, and you can AI chat with anything inside.
Problem 😫 AI chats are powerful, yet everything they produce disappears into a single thread. There’s no way to organize, reuse, or build on top of that knowledge.
🤔 What if an AI chat could live inside a visual, interconnected knowledge system?
✨ Second Brain lets you:
Save AI responses to Pages — clean, editable, shareable docs (think: Notion meets ChatGPT).
Create an AI Visual Board — multiple chats and content nodes in front of you (think: they met Miro too).
Add anything — YouTubes, IG Reels, TikToks, PDFs, GitHub repos, websites, Looms, etc — and chat with them.
Organize everything with Projects and Smart Tags — then chat with a whole project or tag group.
Use the Chrome Extension to save anything from the web in 1 click.
Humanize AI-generated content to bypass detection tools.
Powered by top models: Grok 3 Fast, Claude Sonnet 4, DeepSeek R1, GPT-4.1 — always kept up to date.
🔐 Privacy matters
Data is never used for training, never sold, and never stored on AI providers.
🔮 Coming soon
Add even more stuff to the chat context: YT Shorts, Google Docs/Sheets/Slides, LinkedIn posts, etc.
Ask anything with Global AI Search: “Find all Pages or YouTube videos where ‘marketing’ is mentioned.”
Summarize & Listen: drop content, Second Brain summarizes it into an audio and plays it to you.
Feel free to check it out, watch the demo, and share any feedback, feature ideas, or questions 🙏
Cool product. If you're a visual person and want to leverage AI (from all your content), then this is the perfect tool to do this.
Congratulations on the launch of Second Brain. The approach of combining an AI visual board with a knowledge base is impressive, and I’m interested to see how this can help organize and interact with complex information more effectively :)
The second brain idea resonates a lot, and I believe AI can take it to the next level. Love seeing fresh takes in this direction.
The real challenge, though, is lowering the friction of switching and sticking. Excited to see how this one fits into real workflows. Congrats on the launch!
Congratulations and success for the launch of the Second Brain application! The presence of this platform can be a major breakthrough for anyone who wants to think deeper and organize ideas in a connected way. The future of productivity is just about to begin! Continued success 💪💪
I read a lot every week from different websites and apps. Can I chat with Second Brain, send all the links or screenshots I read to it, and Second Brain can then summarize a weekly/ monthly digest for me?
Exactly the kind of tool I’ve been looking for — can’t wait to try it out! 🚀
Any plans for integrations with Make or Notion?
Congrats @Second Brain team on the launch. This is the most functional vision board i have ever seen. This is a great productivity tool to keep track of AI activity.
I have to admit, that as a power user who has tried similar tools extensively over the past years, I've become vary on trying new stuff. It doesn't matter which second brain AI app I tried, I always run into the limitations quickly.
I guess the issue is the underlying AI models, that by themselves already promise things they can't fulfill.
I'm currently producing an online course out of my own book (380 pages) and other resources from other books.
Unfortunately the real context window of all the AI tools is about 60k Token. They become unresponsive after 100k - faaaar below the claimed 1M token (from OpenAI). My book alone needs 70k - so every other source I add breaks the system. So my question is: How much context can your tool handle IN REALITY?
If you'd ask me, I wouldn't consider myself a "power user" just for uploading 1-2 books, but that seems to be the reality.
Maybe most users are happy to chat with a few short PDFs and I'm one of the few who needs a (what they call) "massive" context window of several books. Oh boy...
Second Brain is such a perfect name for this—it actually feels like an extension of your mind! 🧠✨ Love how it bridges the gap between AI chats and visual organization (Notion + Miro + ChatGPT = genius). The fact that you can chat with anything—PDFs, videos, even GitHub repos—is mind-blowing. 🤯 And that provacy promise? Cherry on top. This is the next level productivity! Killer work, Dom! 🚀
Really cool idea. I've always loved the node based systems and their visual representation.
This is definitely an interesting problem you're solving because the AI chats are scattered all over the place.
I wish there were 15 days trial before committing to any paid plans. Pls consider.
Second Brain sounds like a game-changer for anyone looking to organize AI knowledge in a more meaningful way. I'm really interested in how the AI Visual Board lets you work with interconnected nodes. Do you think this approach could be used for complex project management as well?
Literally been drowning in scattered AI chats recently - Tryna find the one that works best for me tbh & the ability to save responses as proper pages + organize them visually is exactly what I've needed - Never thought I'd see the day I could chat w/ a Youtube vid lol!!
Can't wait to see how Dom and the team evolve this concept further!
our AI-powered visual board and knowledge base for organizing ideas and insights. Capture thoughts, connect concepts, and boost productivity all in one place.
Great control panel.
This way, I can see which pages are linked at the same time.
Love how Second Brain brings structure to AI conversations, something that's been missing in most tools. Does it support syncing across devices or team collaboration for shared knowledge building?
