Recommended. Some models have no such provider; turn this off if a model refuses. Nightroll stores nothing, but cannot speak for what OpenRouter or providers keep.
Saved results
Every AI result (text, pictures, conversations) is saved in this browser the moment it arrives, even while it is still being written, and kept for 30 days, up to 200 results; the oldest are removed first. It never leaves this browser.
How to get set up
- Create an account at openrouter.ai.
- Add credit on its credits page. A few dollars go a long way: most requests cost a fraction of a cent. Free models also work, with daily limits.
- Click Connect OpenRouter above and approve. OpenRouter creates a key for Nightroll in your account and hands it to this browser only.
- Optional: on OpenRouter’s keys page, give that key a credit limit so it can never spend more than you choose.
- Pick a model below. Every AI tool uses it, and the cost of each request is shown with the result.
