Your keys follow your Reddit account
Connect your Reddit account first (read-only) — your API keys are then stored encrypted against it, work from any device, and unlock unlimited briefs & chat.
Key questions
Where is my key stored?
Encrypted at rest in our database, tied to your Reddit account. Keys are write-only: never shown again in full, never logged, never placed in URLs, never returned by the API — you only ever see a masked hint.
What does adding a key unlock?
All briefs and chat run on your own provider quota instead of RedditAsk's included AI — the daily caps disappear entirely, and you choose exactly which model does the analysis.
Can I remove it later?
Any time, from Model Settings or the account menu — removal is immediate. If you have another saved key it takes over; otherwise you fall back to the included AI with daily limits.
