We can supply the AI for you.
If you don't have a subscription to an AI model, we can provide one for an additional monthly charge. No accounts to set up with anyone else and no API keys to paste.
Every plan uses one meter for AI, calls, texts and email. Usage is spread over 4-hour windows so nobody uses the whole month on day one, and you can top up any time.
Pricing questions
Is Sulla Desktop really free?
Yes. The app is free to download and use, and the source code is on GitHub.
What does "bring your own model" mean?
You connect an AI account you already have, such as Anthropic, OpenAI or Grok, by signing in or pasting an API key. Sulla uses it to think, and the provider bills you directly. Desktop, Cloud and Mobile stay free.
When would I pay Sulla anything?
Only if you want us to supply the AI model. Pick a plan above and the AI is included, up to the plan's monthly usage.
What happens if I hit my plan's usage?
Sulla pauses AI work until the next window opens, or you can top up right away. Nothing is charged beyond your plan unless you top up.
Can I switch between my own model and a plan?
Yes. You can connect your own provider at any time, and you can start or cancel a plan from your dashboard.
Start free. Add AI only if you need it.
