We are changing who gets API access in Writingmate. Starting November 14, 2026, API access is part of the Ultimate plan. It is no longer part of the Pro plan, and so it is no longer part of AppSumo plans either. You can still use the API on any plan if you add a card for pay-as-you-go.
This post explains what changed, why we did it, and what you can do if you use the API today.
What changed
- Ultimate plan: API access is included, same as before.
- Pro plan: API access is no longer included.
- AppSumo plans: API access is no longer included. Under our AppSumo agreement, AppSumo plans get the features of the Pro plan, so they follow the Pro plan here.
- Any plan with pay-as-you-go: API access is included. Add a card, and you can use the API on Pro, AppSumo or any other plan.
Free and trial accounts do not include API access.
Why we made this change
When we launched API access, we hoped it would help the people Writingmate is built for: small business owners, creators and marketers who use Writingmate every day to get real work done.
After a few months, the numbers told a different story. None of our monthly or yearly customers were using the API. Almost all API use came from AppSumo accounts, often running agents and other tools around the clock. That is not who we serve, and it is not what Writingmate is built for.
We would rather put our time into the app our customers actually use. So we kept the API for the plan that is meant for heavy use, Ultimate, and for anyone who wants to pay for what they use.
Your existing API keys
We turned off all existing API keys as part of this change. Keys on the Ultimate plan were turned back on.
If you saved a Writingmate API key in another app or service, delete it there. If you keep API access, make a new key and use that one instead.
How to keep using the API
- Go to Settings, Billing.
- Upgrade to the Ultimate plan, or turn on pay-as-you-go by adding a card.
- Go to Settings, API keys and make a new key.
With pay-as-you-go, you pay only for what you use, at a set monthly limit you choose.
What you will see if your plan does not include the API
If you call the API with a key on a plan that does not include it, you get an error with status 403 and the code api_access_requires_ultimate. The message tells you how to get access back. Making a new key in Settings shows the same message.
What does not change
Chat, images, video and everything else in the Writingmate app work just like before, on every plan. This change is only about API keys.
