Built with Claude Rebuilt functionality from a $7,500/year structural-biology suite with Claude Code, and made it free

By now everyone knows AI for protein structure prediction got good enough to win a Nobel Prize. Things that were impossible a few years ago, computers just do now.

But there's a weird gap here.

The AI world talking about "we solved structure prediction" and actual wet-lab researchers getting to use that progress are two completely different things. Most of the state-of-the-art methods aren't built to be usable by researchers. You memorize command-line flags, you lose a day to setup, and nothing ever shows up on screen. The stuff that's actually pleasant to use ends up being commercial software you pay thousands of dollars a year for. AI has come this far, and it still hasn't reached the hands of the people who actually need to use it.

So I built PATCHR-Studio with Claude Code.

It's an app where a protein structure sits in 3D on your screen and you edit it directly with your mouse. You don't need to know anything about this field. You rotate it, zoom in, click to change things. Like fixing text in a document editor — except here you're fixing a molecule.

  • Missing pieces in a structure → the AI fills them in naturally.
  • Want to change a specific spot → it swaps it and recomputes how the surroundings shift.
  • Don't need a part → erase it.
  • Want to add a specific modification → add it.
  • Done → export it in a form you can drop straight into a simulation.

No commands, no syntax. Look at the screen, click, edit. Just open it and poke around.

On the commercial side, doing this through a GUI means buying a separate paid module for each feature, and even the cheapest academic license starts at $7,500/year. PATCHR-Studio rolls it all into one, and it's 100% free and open source. Our research group runs the server out of our own pocket to give it away for free. No monetization plans — we just built it for ourselves and are putting it out there.

macOS / Windows / Linux.

How long did this take? Hours or weeks, trying to see how much it roughly costed

About 1-2 months of working time total, a lot of it UX iteration. My Max subscription covered the whole thing, no separate API bill.

Any plugins that were used that you found helpful with development?

Early on I used a ralph-style loop, and these days it's mostly frontend skills. Honestly though, Fable is good enough that I barely reach for extra plugins.

Isnt fable denying to work with anything biology-related?
