A non-developer vibe coded an AI note-taking app and says it is at about $7M ARR as a one-person company
Josh Mohrer built Wave AI, which records, transcribes and summarizes conversations, and still does the engineering and support himself.
Subject: Wave AI (Josh Mohrer)Subscription AI audio note-taking app for iOS, Android and web, sold monthly or annually

Case Overview & Background
Josh Mohrer is not a developer, but Mixergy describes how he vibe coded Wave AI into a $7 million a year note-taking company. The app records what you say in meetings, on calls or straight into your phone, then transcribes and summarizes it. He says that over about three years a few people helped with higher-end engineering and marketing, but he has done most of the engineering and all of the support himself.
How AI Is Used
Step-by-Step Process
He says there were few AI note-taking apps in the App Store when he launched.
He works in Cursor across the app and web app repos and has added Claude Code.
He uses Apple Search Ads for iOS and Google Ads for Android, at about 800 to 1,000 installs a day.
He built small free tools whose saved summaries bring a couple thousand search visits a day.
Customer Acquisition & Distribution
Limitations, Risks & Failure Modes
What may not apply to you, and what could go wrong:
- The figure is self-reported and was not independently checked
- He says revenue has been flat for a few months
- AI note-taking is now crowded, including large companies
- Paid ads are a main channel, so acquisition costs matter
Key Takeaways
- A non-developer can build and run a large app with AI coding tools
- App Store ratings and search ads can drive steady installs
- Small free tools can add search traffic at almost no cost
