Earnings evidence

These are named, founder-reported examples of focused AI software earning subscription revenue. Distribution and domain expertise mattered as much as the build.

✓ Reported earnings

$29K MRR from an AI blogging platform

Ryan Robinson and Andy Feliciotti reported $350,000 ARR for RightBlogger. The product reached its first $2,000 MRR in launch week, helped by Robinson’s large pre-existing creator audience.

The short playbook

  1. Find a repetitive task people already do badly in ChatGPT.
  2. Wrap it in a dead-simple interface with Claude Code or Cursor.
  3. Charge a small monthly fee; even 100 subscribers is meaningful.
  4. Let churn tell you whether it's a real tool or a novelty.

Tool stack

The buildership a working tool without a deploy pipeline

Free tier · from ~$20/mo

Builds and publishes a working AI web tool from chat prompts, hosting included, and you own what you build. The free tier is 5 build credits a day.

The AI behind itusage-billed: costs scale with your users

Pay per use

The engine your tool calls. A typical request on Haiku costs about a third of a cent, so a thousand uses runs about $3.50.

Pay per use

The cheapest per-request option and the default in most tutorials. The same thousand uses costs under a dollar on the nano model.

Ship and chargehosting that allows commerce, checkout that does the taxes

Free · $5/mo for 10M requests

Hosting whose free tier allows commercial use: 100,000 requests a day, and over-limit traffic errors out instead of surprise-billing you. $5/mo covers 10 million requests.

Free · 5% + 50¢ per sale

Merchant of record, so sales tax and VAT are its problem instead of yours. The single biggest paperwork remover for a first paid tool.

Free

The standard day-one distribution channel for tiny tools: submit, get upvoted, reach buyers. Expect a wave of agency spam messages after launching.

Common questions

Do I need to know how to code?

No. Lovable builds and publishes a working web tool from chat prompts, hosting included, and its terms say you own what you build. Code helps when things break, but it is not the entry ticket.

What does it cost to run one?

Near zero at small scale. A thousand AI requests cost about $0.85 to $3.50 depending on the model, Cloudflare hosts free with commercial use allowed, and the checkout only takes a cut when you sell. A tool with a few hundred users typically runs under $10 a month.

How do tiny AI tools make money?

One-time purchases or small subscriptions through a merchant-of-record checkout that handles sales tax for you: Lemon Squeezy takes 5 percent plus 50 cents, Gumroad 10 percent plus 50 cents. Launch distribution starts free on Product Hunt.

What is the gotcha nobody mentions?

API costs scale with your users: every request costs tokens, so a viral day bills you linearly, and both API platforms let you cap monthly spend in the dashboard. On hosting, Vercel's free tier bans commercial use while Cloudflare's allows it.
