How it rates

ValuationFair

Similar mobile apps we've tracked mostly ask 2.7–4.7x profit, or 2.3–4.0x adjusted for its higher risk; this one asks 3.1x.

Durability

Just over 2 years old, all sales through Apple's App Store, and last month's revenue was below its 12-month average.

Hands-off

The sellers say it takes no weekly hours, and a third-party AI service does the rewriting.

Why it's interesting

  • All growth has come from organic App Store demand; the sellers say they have never spent on ads.
  • Rated 4.6 from more than 1,250 reviews, with refunds around 0.5% and 72% of revenue from renewals.
  • Profit runs at about 82% of revenue, and the AI service that does the rewriting costs about 0.1% of revenue.
  • Revenue can be checked through read-only RevenueCat access, and the Flutter codebase can be built for Android.

What to watch

  • Every sale goes through Apple's App Store, 81% of revenue comes from the US, and the app has had no update since Nov 2024.
  • About 87% of revenue comes from a $4.99 weekly plan, and weekly subscribers tend to cancel sooner than yearly ones.
  • Last month's revenue of about $8.5K was below the 12-month average of about $9.7K, which suggests growth may have stalled.
  • It competes with Undetectable AI, QuillBot and others in a young category, and it depends on beating AI detectors that keep changing.

Ask the seller

  1. What were revenue, new subscriptions and active subscriptions in each month since launch?
  2. How long do weekly-plan subscribers typically stay before cancelling?
  3. Has Apple ever raised review concerns about the app, and how well does its output still pass current AI detectors?

Growth plays

  • Test Apple Search Ads on 'AI humanizer' and 'rewrite AI text' keywords, since the sellers estimate $1.40–2.20 in revenue per install.
  • Publish the existing Flutter build on Google Play to reach Android users.
  • Promote the yearly plan to students before term starts, which could cut reliance on weekly subscribers.

How we rate

Every business gets three ratings, each with a one-line reason. They describe the business; they don't decide whether it's listed.

FairHighLow ⚑Valuation
The asking price compared with similar listings we've tracked, adjusted for the business's record and size. Low means cheaper than most similar listings: ask why before anything else.
Durability
Whether the profit is likely to last. Three dots usually take 5+ years (never under 3), steady or growing sales, and no reliance on one platform, one traffic source or paid ads alone.
Hands-off
How little of the owner's own time the business needs. Three dots: under about 10 hours a week, or a team runs the day-to-day.

A dash means the listing doesn't say. Businesses listed before we started rating, in early November 2026, show no ratings.
