There is no Unprompter server in the path.
The extension talks straight to the model you configure. That is why there are no credits to buy, no queue to wait in, and nothing of yours sitting on our disk.
A key you already have
OpenAI, Anthropic, Google or OpenRouter. Paste the key once, hit Test this setup, and you are done. A 1024px image on a small model runs at roughly a tenth of a penny, billed by your provider to you at their price — not ours.
Or nothing at all
Point it at Ollama or LM Studio on your own machine and the picture never leaves the building. Every reading is free, there is no rate limit, and it works on a plane. A vision model like qwen3-vl:8b is enough.
| Provider | What it needs | Runs | Cost per image |
|---|---|---|---|
| OpenAI | An API key | Their servers | Fractions of a penny on the small models |
| Anthropic (Claude) | An API key | Their servers | More per image, and the most careful reader of the set |
| Google (Gemini) | An API key | Their servers | Cheap, fast, generous free tier at the time of writing |
| OpenRouter | An API key | Whichever model you route to | Their published rate for that model |
| Ollama | A vision model pulled locally | Your machine | Nothing |
| LM Studio | Its local server switched on | Your machine | Nothing |
| Anything OpenAI-compatible | A URL, and a key if it wants one | Wherever you host it | Yours to decide |
Why this way round
Credits are a business model, not a feature.
A tool that sells you credits has to run a server, mark the tokens up, and keep your images long enough to process them. Bringing your own key removes all three: you pay wholesale, you keep your pictures, and the only thing we charge for is the software. Once.
No markup
You pay your provider's list price. There is no per-image margin for us to protect, which is why the batch and variation features exist at all.
No dependency
If unprompter.dev vanished tomorrow, the extension would keep reading images. The only thing it uses our server for is claiming a Pro seat.
No ceiling
Want to read four hundred images off a moodboard on a local model at three in the morning? Nothing here stops you.
