When analyzing standard grammar keyboards, we realized almost all of them utilize a pervasive background listener, reading every single keystroke as it happens. This architecture is necessary for real-time red underlines, but it comes at a massive cost: total loss of privacy.

TypePilot was built on a strictly inverse principle: we see nothing until you ask us to look. By anchoring our AI capabilities to an explicit 'Enhance' button, we keep your typing entirely sandboxed at the OS level. When you do click Enhance, only the current text box content is transmitted over an encrypted tunnel to our stateless edge servers. The text is processed, injected back into your screen, and instantly purged from memory. This zero-retention click-to-activate model ensures you get the power of cloud LLMs without sacrificing the security of a local keyboard.
