No. MNEMOS uses a single AI engine on the backend to build your memory and generate exports — you never need to sign up for or manage separate API keys for the platforms you use.
Your account drops back to the Free plan and the 25-fact limit applies going forward. Nothing already stored is deleted just for downgrading — cancel any time from your dashboard's billing portal.
No — it's entirely optional. Copy-paste works exactly the same with or without it, and the extension itself falls back to copying to your clipboard if it can't automatically fill a page.
No. Nothing reaches Claude, ChatGPT, or any other platform until you choose to paste it in, or click to auto-fill it with the extension.
