Open Source Alternative to Google Docs
Google Docs is free, but your documents train their models. CryptPad gives you collaborative docs with end-to-end encryption.
What the paid app costs: Free (privacy cost)
Why switch?
The price of Google Docs is your data. CryptPad's zero-knowledge encryption means even its operators cannot read your documents, and OnlyOffice gives teams a self-hosted Workspace-style suite. Your drafts stay yours.
