What “bring your own key” AI means, and why resellebee works that way
Many tools sell “AI credits”: you pay the tool, the tool pays an AI company, and keeps the difference. resellebee does it the other way round. You bring your own key from the AI company you choose, and pay that company directly, at its own price.

What a key is
An AI company gives each customer an API key: a long password that lets a program ask its models for text on that customer’s account. You create one on the company’s website, and the company bills you for what the key is used for.
What it changes for cost
With credits, you pay the tool’s price for each piece of writing. With your own key, you pay the AI company’s own price, with nothing added. A listing is a few short lines, so each one is a small request; what that costs is on your provider’s price page, which is where you should read it, not here.
You also choose the model: a stronger one for better writing, a cheaper one when that is enough.
What it changes for privacy
Your key is saved in the extension’s own storage in your browser. It is not sent to resellebee, and it is not shown again after you save it. When you press “Rewrite with AI”, your browser sends the item’s facts straight to the provider you chose. The request does not pass through our servers, so we never see the key or the text.
What is sent: the item’s name, brand, category, who it is for, size, colour, condition, your notes and the language. No price, no photos, nothing about you.
Which providers work
Anthropic (Claude), OpenAI (GPT), Google (Gemini), Mistral, xAI (Grok), DeepSeek, Groq, OpenRouter and Together AI are built in, and so is “any other address that speaks the same language”, which covers a model you run on your own computer.
A fair warning: we checked that each of these providers accepts requests from a browser extension, and we test the requests against stand-ins. We cannot test with a real key of yours. If a provider answers with an error, the extension shows you the provider’s own words.
How to set it up
Create a key on your provider’s website. In resellebee’s settings, choose the provider, paste the key, press “Load models” and pick one. Then “Rewrite with AI” appears on every saved item. The AI rewrite is part of the subscription; the built-in writer, which needs no key, is free.
