Drag raw captures in. Style them into store-ready panels. Span one shot across two slots as a tilted panorama — with the App Store gutter previewed, so you judge the seam the way buyers will see it. Or go fully hands-off and let an AI agent drive the whole thing over MCP.
See how exports work Coming to the Mac App Store — in TestFlight now.Screenker is the first screenshot studio you can run by conversation. Every feature is scriptable over a local, off-by-default MCP server — so an agent can build panoramas, restyle a gallery, critique it, and publish to App Store Connect while you stay hands-off. Works with Claude Code, OpenAI's Codex, and any MCP client.

One screenshot, two or three store slots, one tilted device across the seam. Drag the device on the canvas, scrub the angle, and let seam-gap compensation keep edges aligned across the gutter when the slices are cut.
Minimal, Dark, Bold, Playful — each one shippable as-is, every knob editable after: gradients, any installed font, caption position, per-panel overrides.
The device frame is drawn, not licensed — continuous corners, Dynamic Island, side buttons — and parametric to any export size, iPhone or iPad. Or go bare with a corner-radius slider.
Suggest Captions returns 3–5 headlines in your preset's voice, read from the screenshot itself. Bring your own Claude or OpenAI key in ⌘, Settings; keys stay in your Keychain — never in your project files.
Give a two-screen panorama a separate title on each half, so the store gutter falls cleanly between them and never splits a word.
Filled caption bands for legibility, shadowed media plates that float bare media, and full-bleed photo backgrounds with a focal-point safe-area guard so the subject never crops.
Spotlight the detail that sells — a live crop of the slide's own screenshot, with chrome, a leader line, and optional depth-of-field so the lens pops.
Import your current set and publish the finished gallery back with your own ASC key. Keep a working set bigger than the 10-shot limit and pick which slides ship.
Export All renders every panel for each store size you check — one folder per size, numbered in gallery order, panoramas producing consecutive slices. Every PNG is exactly the preset's dimensions, RGB, no alpha. It's the format App Store Connect requires, so uploads pass the first time.
