A small app studio.

Besides the social media manager, we make four apps, design websites and publish Claude skills. Looking for the social media manager? Start here.

How the studio works

Chockstone Labs LLC is a founder-run studio in Chagrin Falls, Ohio, formed in 2026. We keep it small on purpose: the founder builds each app, writes its website and answers its support email, so the work stays close to the people each app is for.

Each app stands on its own, with its own website, account, pricing and privacy policy. A Chockstone Labs plan covers the social media manager only.

Website design

We design and build websites the way we build our own.

  • Every word is in the HTML the server sends, so search engines, Claude and ChatGPT read the whole page.
  • Fonts load from your own domain, so no font host sees your visitors.
  • Structured data, a sitemap and an llms.txt file come with every site.
  • Light and dark themes, laid out for a phone first.

Tell us what the site is for and when you need it.

Claude skills

A skill is a folder of instructions and scripts that Claude loads when a task needs it. We publish the skills we use in our own work.

Skill 01

video-edit

Claude Code

Plans, cuts, captions, animates and renders video with code.

Claude picks lines and shots by number, and the scripts do all the timing, frame-exact, through one edit decision list. Every cut lands in a pause between words. Needs Python 3.10 or newer and ffmpeg 7 or newer; the Swift tools need a Mac.

Skill 02

humanize

Claude Code

Finds and removes the patterns that make text read as machine-written.

Each tell in its catalog has a stable id, and a scanner with no dependencies finds them in a page, a pasted draft or a whole project's copy. Claude rewrites the hits, and a hook flags new ones right after Claude writes them.
