FAQ

Do I need to know how to code?
Not at all. You describe what you want in plain English. We handle everything else.
Where does the agent actually run?
On our secure VPS. You don't need to install anything or manage any infrastructure.
Which platforms are supported?
Telegram, Discord, Slack, WhatsApp. Your agent is a contact in your phone, not a website.
How do I set up my API key?
After subscribing, you provide your OpenRouter, Anthropic, or OpenAI key. You can change it anytime from your settings.
How much will LLM API calls cost me?
Typical usage of ~30 min/day might cost $5-15/mo through OpenRouter. You have full control over model choice and spending.
Is my data safe?
Yes. Your API key is encrypted. We never share your data.
How long does setup take?
Under 2 minutes. Pick a plan, connect your chat, and start talking.
What is the difference from ChatGPT?
ChatGPT is a chatbot you open in a browser. Mercury is an always-on agent that lives in your chat apps, runs scheduled tasks, scrapes the web, and remembers you across days.
What happens if I stop paying?
Your agent is paused and data retained for 30 days. Resubscribe to resume where you left off.
Can I cancel anytime?
Yes. Monthly subscription, no lock-in, no hidden fees.
