Show HN: Echo, AI voice and text notes

Hi 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.

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. The most common use-cases our users share with us are: - Habit building by capturing how you feel instead of just counting events. - Getting unstuck when writing by talking out loud. - Capturing inspiration when it strikes. - Boosting creativity through daily ramblings.

Personally, I use Echo to think through a syllabus for a law school class I'm teaching in the fall. I'm a lawyer turned software designer and I've always struggled to write, but I get energized when talking about my ideas. So, I take Echo for a walk and just talk my way through what I want to teach these students. After a couple days of this, I ask Echo to draft a syllabus for me.

Echo is free to use. We're still very early-stage and would love your feedback. You can reach me at thomas@echonotes.ai

Thank you!

p.s. We're launching on Product Hunt today. Wish us luck.
