19 Jev + Claude Code Use Cases (With Prompts)
A decision-only model built for picking, not writing, paired with Claude Code across nineteen real automations, from spreadsheet tagging to routing which Claude model handles a prompt.
October 4thArtCraft cloned seven Adobe apps from scratch in Rust, open-sourced the code, and built them so Claude Code can drive every one.
ArtCraft used Claude Opus 5.5 to build legal, open-source, clean-room clones of seven Adobe apps in Rust, and because each one ships a CLI and an AGENTS.md handbook, Claude Code can drive the software directly instead of only generating a finished file.
ArtCraft, a group using Claude Opus 5.5, built clean-room, open-source rebuilds of seven Adobe apps in Rust: PhotoCraft (Photoshop), FilmCraft (Premiere), EffectCraft (After Effects), VectorCraft (Illustrator), DesignCraft (InDesign), LightCraft (Lightroom), and PDFCraft (Acrobat). Because it's a clean-room reimplementation rather than reverse-engineered code, it's legally distinct from Adobe's software. Every app is free at getartcraft.com or on GitHub, and each ships a CLI plus an AGENTS.md handbook so Claude Code can drive it directly from a single prompt. Tests inside EffectCraft and DesignCraft show Claude producing real first drafts, but the reviewer's conclusion is that one-shot AI generation still wins on first-draft quality while layered software stays easier to refine by hand.

Claim stated: Claude-built, open-source clones of Photoshop, Premiere, After Effects, Illustrator, InDesign, Lightroom, and Acrobat.

Defines clean-room reimplementation, explains why building from scratch in Rust keeps ArtCraft legally clear of Adobe, and points to getartcraft.com and the GitHub repo.

Hands-on tour of the Photoshop clone: text editing, effects panel, layer styles, already at 20,000 GitHub stars hours after launch.

Tour of the Premiere Pro clone: timeline zoom, clip scaling and positioning, familiar editing shortcuts.

Tour of the After Effects clone, called the hardest app to replicate: sparks layers, lens flares, motion graphics capability.

Quick pass through VectorCraft (Illustrator), DesignCraft (InDesign), LightCraft (Lightroom), and PDFCraft (Acrobat).

Tests whether Claude Code can operate the apps directly: one prompt builds a full logo animation in EffectCraft and a magazine layout in DesignCraft, enabled by each app's CLI and AGENTS.md handbook.

Weighs layered editing software against one-shot AI generation models: AI creation gives great first drafts that are hard to refine, manual tools give weaker first drafts that are much easier to refine.

Credits ArtCraft for shipping seven apps at once, recommends trying them, closes with a subscribe ask.
ArtCraft's free, open-source Adobe clones are legally clean because they're built from scratch, and they let an AI agent operate the software, not just generate a file.
“If we're talking about a clean room reimplementation, that essentially means that they didn't take Adobe software and reverse engineer it... they rebuilt it from scratch, which means that it is perfectly legal in this case.”
“Photocraft here already has 20,000 stars only a few hours after they launched.”
“I find that it's much harder to refine for you to get to the final result and look that you want... it is actually much harder to polish.”
“If you are into creative work, then this is definitely worth checking out, especially since it is open source and free.”

A YouTuber opens with the claim that stops the scroll: someone used Claude to rebuild the entire Adobe suite from scratch and gave it away free. What follows is a hands-on test of whether that claim holds up, and whether Claude can actually operate the software it helped build.
A two-column tradeoff the reviewer draws on screen to argue layered creative software still has a place even as one-shot AI generation models improve.
Seven clean-room, open-source Rust rebuilds, one per core Adobe app.
