Where this came from (Reddit)

People want meeting and lecture notes without uploading private recordings to a cloud service.

The threads (in our words)

Reddit blocks automated reads, so we couldn’t record upvote or comment counts. Revenue figures are the poster’s own claim (self-reported), not verified. The business below is our own design inspired by these threads.

Who it’s for

Students, journalists, researchers and anyone who records meetings or interviews.

Adapt it to your industry

  • Start with one niche or customer type, then expand.
  • Ask your first 10 customers what they would pay before you build more.
  • Keep a human check on anything sent in a customer’s name.

Step by step

  1. Build the app with Cursor around an open on-device speech model.
  2. Add speaker labels, summaries and export to notes apps.
  3. Sell a monthly plan and a lifetime option through in-app purchases.
  4. Write App Store pages and SEO posts for each use case (lectures, interviews, meetings).
  5. Post short demos on X and answer questions on Reddit.
  6. Watch crash reports and reviews daily and ship fixes weekly.

Your autonomous stack

Autonomy: Agents write, produce and publish on a schedule. Your part: Weekly: approve the next batch before it posts (about 1 hour).

Every layer an agent-run business needs, in order. Prices are public list prices, checked Oct 16, 2026.

  1. Agent (the brain): Grok Bot (agent + scheduled routines) (opens in new tab) (Included with The X Subscription Premium $30/mo (Super $100/mo for more usage; Plus $8 does not include Grok Bot)). Grok Bot runs the business day to day: writes, answers, decides small things and reports to you. Claude Code or Codex are alternatives.
  2. Build and hosting: Cursor (opens in new tab) (Free tier · Plus $8/mo · Premium $30/mo), Supabase database (opens in new tab) (Free tier · Pro from $25/mo). The product or service your customers use.
  3. Payments: Stripe payments (opens in new tab) (No monthly fee · 2.9% + 30¢ per card payment). Automatic checkout and receipts. Other options: PayPal Checkout (3.49% + 49¢) or Lemon Squeezy (5% + 50¢, handles sales tax).

  7. Monitoring and schedule: Grok Bot (agent + scheduled routines) (opens in new tab) (Included with The X Subscription Premium $30/mo (Super $100/mo for more usage; Plus $8 does not include Grok Bot)). Grok Bot scheduled routines run each day: send, check for failures, alert you if something breaks.
  8. Analytics: Google Analytics (opens in new tab) (Free). Tracks visits, signups and sales so the agent can report what works.
  9. Human checkpoint: Weekly: approve the next batch before it posts (about 1 hour).
  10. Price: charge $7 per subscriber (monthly subscription (in-app)). Offer the first 3 customers a founding price for honest feedback.

What they did

A phone app that transcribes recordings on the device, separates speakers and turns meetings and lectures into notes, with nothing sent to the cloud. We designed this business from real Reddit threads; it is an idea for you to build, not a description of the posters’ businesses.

How it went

Found on Reddit in r/EntrepreneurRideAlong (1 thread). Upvote and comment counts weren’t retrievable, so none are shown. On X, 96 posts matched our search for this idea in the 7 days to 2026-10-17.

Worth knowing

Tell users to get consent before recording others; recording laws differ by place.
