Where is the demand coming from?
Leans on the founder
The founder's audience is a large part of it. This is the read that decides whether the traction would transfer to you.
Roughly what does it earn?
Not disclosedNo basis to estimateWe do not publish a figure until we have something to base it on. When we do, the method that produced it is shown alongside the range.
Could you build it?
Yes, in about 2 weeks
Nothing patented, no network effect, and no proprietary data set standing in the way.
What it is
Praesto is an on-device note-taking and transcription app for iPad, iPhone, and Mac designed to keep students engaged during lectures and meetings. It combines live transcription, handwriting recognition, slide integration, and AI-powered Q&A to help users capture and retain information in real time, with spaced-repetition study tools for later review.
The one thing to knowThe founder has limited observable reach (single r/SideProject post, low velocity), no corroborated revenue signals despite pricing at $9.99-12.99/month, and the core value (on-device transcription plus note organization) is highly copyable by established players like Apple or Notion in under 20 days.
