Getting paid for making someone else's AI easier to work in
Open the real page ↗typingmind.com · alive as of 2026-08-31
This product does not replace ChatGPT. It sells a better place to do work with it — and it never pays for the model, because the customer plugs in their own API key. That single decision keeps the operator's AI cost near zero. ⚠️ The founder has published monthly revenue figures. We do not repeat them: no source independent of the founder exists (grade B).
In plain words
ChatGPT already exists. This founder sells a workspace built on top of it for people doing daily work. The customer pays the model provider directly, so the operator carries almost no AI cost.

What is sold
Subscription and licence; team and enterprise controls sit in the higher tiers
Pricing is published on the official site (liveness confirmed 2026-08-31). ⚠️ We do not copy the figures across. This site publishes only values it has checked itself, and price checks run on a separate monthly routine in the tool directory.
Who buys
People and teams using AI in daily work, plus companies that need an internal deployment
What arrives is not what you keep

- What is leftAt or below zero, it is not a price
This case does not publish its own tool costs, fees or tax. So we show the order and the items only — put your own numbers into the calculator.
AI's part and the person's part
Already had
A developer. This is not a non-technical person's first build. Read the starting line as engineering skill plus an audience that was already there.
If this is large, the AI is not the reason
What the AI did
No model is trained here. It is a client for other people's models. Calls leave on the user's own API key, and what is actually sold is the working experience: organised threads, saved prompts, team sharing, switching models.
the part a tool replaced
What the person did
Product judgement, engineering, and the trust built by working in public. The founder is a developer with an existing audience, and that audience overlaps with the first customers. ⚠️ This is the bottleneck for anyone copying it — the audience existed before the product.

How we verified this
Public dashboard or platform figure. May be self-reported
Confirmed — the service is live (official site HTTP 200, 2026-08-31), the founder is named, and the founder's newsletter post exists (HTTP 200, 2026-08-31). Not confirmed — revenue. The monthly figures and the claim that over half is recurring B2B come from the founder's own newsletter. There is no payment-processor verification and no independent reporting, so this is not grade A and we publish no amount (CLAUDE.md §2.1).
- Official site — liveness confirmed (HTTP 200) (official_site · checked 2026-08-31)
- Founder newsletter — the origin of the revenue claim. Founder-published, so treated as supporting evidence only (founder_interview · checked 2026-08-31)
What made it work
There is a paid position directly above a general-purpose model: the working experience. You do not need to build a model, and every improvement to the underlying model makes your position larger, not smaller. What converted one-off interest into recurring revenue was the admin layer. The moment an individual brings the tool into a team, accounts, sharing and access control become someone's problem — and that is where subscriptions begin.
Risks
- If the model providers absorb these features, the reason to pay shrinks. The official clients keep adding team functionality.
- Asking users to supply an API key is a real barrier — for a non-technical buyer the first screen is the hardest one.
- Revenue rests on the founder's word alone. Do not treat the amounts as established.
Does this work in Korea?
The transferable part is the cost structure. When the model runs on the customer's key, the operator never carries the inference bill — a structural answer to costs that climb as usage grows, and it holds in Korea unchanged. The hard part is the audience. Early demand here came from years of public work. Ship the same product with no audience and you get a good tool nobody has heard of.

7-day action plan
Step 1. Write down three things you redo by hand every time you use an AI interface
Step 2. Check in a community whether one of those three is other people's problem too, not just yours
Step 3. Work out your fixed monthly cost if the model ran on the customer's key instead of yours
30-day action plan
Step 1. Build the one fix that annoyed you most and put it in front of ten people
Step 2. Before charging, ask users directly what they would need to bring it into a team
Step 3. Decide which feature separates individual from team use, and price only after that
Run the numbers
We do not print a single projected figure here. Put your own numbers in instead.

Words you may not know
- Verification grade
- How far we checked this case. A means the revenue was confirmed by someone other than the founder; B means the business exists but the revenue is only the founder's word.
- Revenue
- Everything that came in. Tools, fees and tax still have to come out before it is what you keep. The two are not the same.
- MRR
- Money that arrives every month, as opposed to a one-time payment.
- Self-reported
- A number the person stated about themselves. Nobody else confirmed it, which is why we do not print those numbers.
- Replicability
- How likely someone else is to get a similar result. The more the founder already knew the field, the harder it is to copy.
