SecondBrain
Build your second brain just by talking, now on the web too
New since our June launch: SecondBrain is rebuilt around your voice, and it now runs in your browser too. Tap and talk: it writes a clean note in your words, files it, and turns dates into events and reminders. No time given? It asks. Share links, PDFs and photos from any app, then watch it work live. Ask anything and the answer streams from your notes. Pro adds one shared memory for Claude, ChatGPT, Gemini and Cursor over MCP. iPhone, Android and web. Free: 10 notes and 3 AI requests a day.
As an engineer with ADHD having a short memory is a mess, I always used to miss calls, forget new great ideas loose documents and so on. I built this for myself, but now more than 3500 users are actively using it, and feedbacks are great. Give it a try and let me know!

Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
