![What People Are Building With AI [Week 30, 2026]](/_next/image?url=%2Fimages%2Fai-builders%2Fweek-30-hero.jpg&w=3840&q=75)
This week: a free Claude skill that strips AI writing patterns (we ran it on our own post and it caught two things our edit missed), a plugin that turns Claude Code into a video editor, Vercel's CEO reporting a 15 to 30 percent Turbopack memory improvement found by Claude, an Anthropic cookbook tool that takes Fable 5 from 29 to 73 percent on chart reading, interactive ascii art built with Kimi K3, and OpenWorker, Andrew Ng's open-source agent that returns finished documents. Every entry links to the builder's original post.
Everything below was posted in the last few days by the person who built it. We watched each demo before it made the list, linked every original post, and tested what we could ourselves.
A skill that deletes AI slop
Peter Yang open-sourced his editing checklist as a Claude skill.
Peter Yang got tired of reading AI-flavored writing, so he packaged his editing rules into a free MIT-licensed skill that detects and removes more than 20 patterns: the binary contrasts, the throat-clearing openers, the dramatic colons. It works as an editor or a detector.
We ran it on our own Claude certification guide, which had already been through our in-house editing pass. It still caught two dead lead-in phrases. Both fixes are live in that post now.
A video editor living inside Claude Code
ChatCut's plugin opens a timeline editor in the Claude desktop app.
ChatCut built a plugin that opens a full editing timeline inside the Claude desktop app, so you and the agent cut footage together: you talk, it edits, and you can still drag clips yourself. It is out now, and they say it costs nothing extra if you already pay for Claude.
An AI-found memory win in Next.js
Vercel's CEO says Claude found it nearly autonomously.
Rauch posted this while answering a question about his AI "holy s***" moments. His answer was that it is every single week now, and accelerating.
Turbopack is code Vercel's own engineers have spent years optimizing by hand. Finding new headroom there is the notable part.
Fable just found a 15-30% memory efficiency improvement in Turbopack / Next.js, nearly autonomously.

A zoom tool that doubles chart accuracy
One extra tool, and Claude reads dense charts at full resolution.
From Anthropic's developer team: models see images as downscaled patches, so fine detail in dense charts gets lost. Their updated cookbook gives Claude a zoom tool that lets it request a full-resolution crop of any region.
The reported effect on their 100-question chart benchmark: Fable 5 jumps from 29 to 73 percent, Sonnet 5 from 13 to 44. Same models, one extra tool.
Interactive ascii art with Kimi K3
Ascii ripples from the 2.8 trillion parameter open-weight flagship.
Kamil Tyborowski has been making interactive ascii animations with Kimi K3, the model we covered in our K3 review. This one is a terminal window full of characters that ripple away from your cursor. His whole announcement was five words: more ascii fun with kimi k3.
OpenWorker hands you finished work
Andrew Ng's open-source agent ends its runs with finished work.
Andrew Ng announced OpenWorker, an open-source agent that finishes tasks with an artifact in hand: a drafted document, a sent Slack message, an updated calendar entry. Ask it to prepare a customer brief or triage your inbox and you get the brief, or the triaged inbox.
The code is open source and free to run.
Also shipped this week
Two launches worth knowing about, from the vendors themselves.
Cursor Router
A model router that picks the model per task, claiming frontier-quality results at 60 percent lower cost. Vendor numbers, so treat them as claims until independent tests land.
Watch the launch demo on XAI role unverifiedCanvas UI
David Haz's html-in-canvas component library runs real-time shaders over interactive UI, and shadcn called it one of the most impressive registries he has seen.

What six unrelated demos add up to.
Claude is turning into a platform. The week's most interesting Claude items were built around the model rather than into it: a video editor in the desktop app, an editing checklist shipped as an installable skill, and Anthropic's biggest number coming from an added tool.
Agents are being judged on finished work now. OpenWorker's entire pitch is the deliverable, and the Turbopack story is a model handing over a real optimization in a production toolchain.
And the playful demos keep coming from open weights. Nobody asked for ascii ripples from a 2.8 trillion parameter model. People tinker most with what they are free to pull apart.
If you are deciding which of these models to build with yourself, start with our task-by-task model guide or the 2-minute model picker.
