ProofShot captures screenshots of running applications and feeds them back to AI coding agents as visual context. Instead of agents blindly writing UI code, they can now see what they built and iterate. Works with browser-based apps and integrates with popular AI coding tools.
Reviewer scorecard
“The team ships fast and responds to feedback. Good sign.”
“As someone who has watched AI agents confidently ship broken layouts, this is a godsend. The visual feedback loop means agents can actually catch that the button is overlapping the nav bar. Design quality from AI coding just leveled up.”
“This fills a real gap in the ecosystem. Worth adopting early.”
“Vision models still struggle with subtle layout issues — off-by-one pixel gaps, wrong font weights, slightly misaligned elements. ProofShot catches the obvious breaks but do not expect pixel-perfect QA. You still need human eyes for production UI.”
“Clean integration — just point it at your dev server and it handles screenshot capture and context injection. The token cost of sending screenshots is non-trivial though, so you want to be selective about when you trigger it. Works best as a verification step, not continuous monitoring.”
