Dev builds real-time writing linter with Jev that prints receipts on violations
On Sept 24, developer jh3yy demoed a real-time writing linter built on typesafe's Jev, drawing attention and resharing across the dev community.
Confirmed
- The tool supports custom rules; the example rule flags anything that sounds like a LinkedIn post
- The hardware gimmick is an external thermal receipt printer that prints the model's judgment on violations on the spot, with sound effects
- Beyond the physical receipt, a UI shows more detailed judgment records
- Cost is tiny: the author reported 1584 requests cost only $0.0504
- The author says he wants to turn it into a local app
Why it matters
- It turns abstract model judgments into tangible, immediate feedback, a playful example of making AI tools physical
- The near-zero cost shows continuously running AI linters are economically viable and easy to embed in daily writing workflows
- A reshare by colinthornton shows the project gained traction in the developer community
