PR Lens Uses Jev 1.14 Vision to Match UI Screenshots to Architecture

X postOhans EmmanuelDemo

Ohans Emmanuel demonstrates how PR Lens integrates with the experimental image capabilities of Jev 1.14 to match pull request screenshots to underlying architecture and data flows in about two seconds.

Key points

  1. TypeSafe AI released Jev 1.14 featuring experimental image input, a larger context window, and a new box type.
  2. PR Lens renders animated architecture and data-flow diagrams directly inside GitHub, GitLab, and Bitbucket PRs, and works as an agent skill.
  3. Using Jev for image matching, PR Lens maps screenshots attached to PRs (such as agent proofs of work) to the relevant system components within roughly two seconds.

Why it matters

Reviewing diffs produced by coding agents can be overwhelming. Connecting visual UI changes directly to the affected backend and frontend architecture cuts down the cognitive load during code reviews.

Analysis

This workflow highlights a practical integration of multimodal LLMs in software development. Rather than treating PR screenshots as static attachments, PR Lens and Jev convert visual output into navigational maps linking directly to the underlying system components.

best code review use case for Jev images so far: PR screenshot in, the architecture and data flow behind it matched screenshot to matches in ~2 seconds Try it on your next PR: t.co/y9KsaeosGs t.co/I7VuJFDTAy t.co/eLhiuKBZKp

  1. @jeremyho the matching
  2. @marthaelax say an agent opens a PR, it's typical to add some screenshots (as proof of work) PR lens (the tool that draws these architecture and data flows) can map the image to underlying system components (architecture/data flow) The matching itself is what's done with Jev
