Questions

Is my X account safe?

Automated posting violates X's Terms of Service, so bans are always possible. The defaults are deliberately conservative (3 replies/hour, 5 to 15 minute delays, human-like writing) and you should use a dedicated account. The kill switch stops the bot on rate limits or repeated API errors.

Where do my API keys go?

They are stored in your browser's local extension storage and sent only to the AI provider you got them from. They never touch our servers, because there are no servers.

Which AI providers work?

Gemini (primary, free), OpenAI, Groq (free tier), Meta Muse (free tier), Mistral (free tier), and OpenRouter. The bot tries them in order and falls back automatically.

Can it work in my niche?

Yes. Niches are data, not code. Define a persona pack (topic keywords, slang, style, personalities) in Settings and the bot scans, matches, and replies in that niche.

How does licensing work?

The license key is a signed token verified offline in your browser. Free tier runs without a key at 10 replies/day. Pro keys are issued after crypto payment and never phone home.
