I’m Iñaki, a teacher and solo maker from Spain. I built NinjaNote because I was drowning in my own voice notes: WhatsApp audios, quick reminders in the car, ideas while walking… and then I couldn’t find anything when I actually needed it.

NinjaNote is my attempt to make that mess usable. It lets you:

Send or upload audio (including WhatsApp voice notes)

Get clean, structured notes instead of raw transcripts

Automatically split one long audio into multiple notes

Auto-categorize notes (tasks, shopping, ideas, meetings, etc.)

Use it in 28 languages (with a strong focus on European languages)

On top of that, you can:

Create reminders based on your notes

Edit notes in real time with other NinjaNote users

Share notes via text (copy/paste into any app)

Organize everything into folders

Attach images and/or links to keep related context together

It’s a web app that works on desktop, mobile, and tablets. Tech-wise it’s built with Next.js, Vercel, Firebase, Capacitor, and an LLM layer on top of transcription.

On the landing page you can try a live demo without registration: record or send an audio and see how it turns into notes before signing up.

Right now you get 3 minutes for free to try it out (no credit card). If anyone here wants to test it more intensively and share detailed feedback, I’m happy to grant extra minutes – just let me know in the comments or reach out.

I’d really appreciate your feedback on:

Where the UX or onboarding feels confusing

Any obvious technical or product gaps you see

Concerns about privacy / data handling from your point of view
