Questions
What do I actually get for paying?
Account-level perks — sync, priority support, early access, and a badge. Every analysis feature is free for everyone, and we would rather say that plainly than invent a paywall.
Do I need an API key?
Yes, on every plan. CogniSphere does not run its own AI service. You bring a key from Gemini, DeepSeek or OpenRouter, or point it at a local Ollama model, and the extension talks to that provider directly.
Does Pro include AI usage?
No. Whatever your provider charges for tokens is billed by them, not by us. Pro does not include credits.
How do I cancel?
From the billing page in your dashboard. Access continues until the end of the period you already paid for.
