OpenScreen is a free, open-source screen recorder and video editor.

Record your screen, then let your AI agent edit it: zooms, cuts, captions, even effects it writes itself.

This demo came from one sentence: "make a demo of the Pele repo".

Trending in 15 s: Regex Marble Run, your regex as a 3D marble run.

Greedy <.+> spans both tags of <b>bold</b>. One ? later, lazy <.+?> stops at the first closing bracket. Then the evil regex /^(a+)+$/: 327,694 steps, no match.

OpenScreen is now a plugin in the ChatGPT desktop app.

Add the marketplace getopenscreen/openscreen, install the plugin, then ask it for a demo video in one sentence. It plans a timed storyboard first, then records, edits and exports the MP4.

I built MuDesktop, the desktop app for Muse Code, Meta's coding agent.

Projects, live tool calls, a review panel, terminal and browser, git worktrees, MCP, and opt-in computer use. Free and open source, on Windows and macOS.

An independent project, not affiliated with Meta.

Trending in 15 s: Diagram Design, an agent skill for editorial diagrams.

One diagram in three styles, then the exploded AI agent stack replays layer by layer. Self-contained HTML + SVG, no Mermaid slop.

Harness², from Google Research: keep the model fixed, improve the harness around it, recursively.

Propose edits, probe them on the same task, compose a better harness, then learn how to improve the next one. On one JobBench task: 43.1 → 77.8.

DeepSeek-V4.1-Flash-1017 in DeepSeek Harness: one request, sped up.

It plans, then turns a bare page into a trail finder: search, difficulty filters, sort by distance, dark mode. Plain HTML, CSS and JS. The status bar reads ~300 tok/s.

Trending in 15 s: Anima, interactive biology figures made by Claude.

Hover a receptor and it explains itself, slide the dopamine level, block D2 and watch the signal flip. Then a firing neuron whose numbers come with their sources.

Trending in 15 s: MonoCode, a GUI for your coding agents.

Its Monos are agents that work across your projects: one request, the Mono starts a session in the project, then reports back with the changes.

Trending in 15 s: llmspeed, feel local LLM speed before you buy.

Same model, same prompt: RTX 4090 1.8s vs MacBook M4 Pro 5.0s. Then a Mac Studio M5 Ultra takes the next race in 1.5s.

Trending in 15 s: REA, reverse engineering for your coding agent.

The agent reads the dinosaur game's running code: speed starts at 6 and increases a little each update while below 13. Then Calculator's % button: 200 + 10% = 220, but 200 × 10% = 20.
