Saner.AI▲677Initially, we thought about this feature due to a bug in our chat interface. And surprisingly, I noticed that POE has just released the same feature. But the distinction is: with us the Multi-bot is designed to streamline the notetaking/working experience -> It allows user to search for external knowledge without switching context Though we are still in the beta phase, I would love to hear your thought/feedback on it :)

Second Brain▲281Hi HN, I'm Dom, a solo founder. I built Second Brain to solve a common issue I had with AI chats: the knowledge disappears. There’s no structure, no memory, and no way to reuse or build on them. So I built a tool that combines AI chat with a visual, interconnected knowledge system. Key features: - Save AI responses into editable docs (Notion-style Pages). - AI Visual board with multiple content & chat nodes (like Miro meets ChatGPT). - Add and chat with YouTubes, TikToks, Audio, PDFs, GitHub repos, Looms, websites, etc. - Organize using Projects and Smart Tags — then chat with full contexts.…

Echo▲192Hi everyone - My cofounder, Reuben, and I have been working on Echo, a voice & text, mobile-first, note-taking app that uses GPT-4o to organize your thoughts and bring them to life. Download here: https://apps.apple.com/us/app/echo-ai-notes/id6503351019 How Echo works: 1. Write or record notes. We recommend going for a walk and just rambling. Echo works well with unstructured thoughts. 2. Echo automatically organizes your notes into topics. 3. You can ask Echo questions, and it will use your notes to generate a response. We launched in the App Store on Sep 3.…

Echosnap Ai▲62Hi everyone, I’m a solo developer and I’ve been working on a small tool called Echosnap AI. I built it because I often get ideas while I’m walking or doing something else, and speaking always felt like the fastest way to capture them. Echosnap lets you record a note and instantly get a clean transcript. It can also translate your recordings and help you stay organized with tags and folders. I tried to keep the app as simple and minimal as possible. This is my first time sharing something on HN, so any feedback or suggestions would mean a lot. Thanks for taking a moment to check it out.

Your 5-layer AI echo journal for real clarity

- 24
I have tried journaling many times but nothing stuck. So I decided to make my own app for myself with these features: * Voice first * Private first * AI chat * Automatic tagging, meaning extraction, and semantic retrieval using embeddings stored locally * Export to LLM the AI angle is especially interesting for me. It allows me to ask questions like: * "remind me highlights and crazy nights in the last 3 months" * "How was I feeling during my trip in Spain and how big of a problem was my breakup" * "How would you judge my overall interactions with Marc after I told him about my problems" the…
