StraightenUp - Posture Assistant

StraightenUp is a web browser extension that acts as your personal AI posture assistant. It helps you maintain proper posture while spending long hours in front of the computer by gently blurring the browser viewport whenever you start to slouch. That subtle blur instantly makes you aware of your posture and prompts you to straighten up.

Instead of nagging reminders or complicated posture trackers, the correction happens naturally in the moment you need it most — right as you begin to hunch over your screen. Over time, this gentle feedback helps you build healthier sitting habits without interrupting your workflow.

Privacy is fully taken care of: everything is processed locally on your own machine, and nothing is sent to the cloud. You can even verify this yourself by simply disabling your internet connection while the extension is running.
