AI-generated content is becoming harder to identify.
I wanted to experiment with something simple:
What if AI detection ran fully inside the browser?
So I built HiYo, a Chrome extension that:
• Detects AI-written text on any webpage
• Runs locally (no text sent to servers)
• Adds anonymous real-time chat on the same domain
Just select any text on a webpage, right-click, and check if it was written by AI. Uses both statistical analysis and on-device ML.
Why on-device?
Privacy.
I didn’t want users to send article content to an external API.
Technical Stack:
– Chrome extension (Manifest V3)
– Local inference logic
– Real-time chat layer via domain-based rooms
Biggest challenge:
Balancing detection accuracy with performance constraints inside the browser.
Still early stage.
Would love feedback from devs here.
