A 40-second brand launch ad
Author’s claim: Claude Fable 5.5 · model not released · not verified by us
About the post
A 40-second launch advert for the author's own brand. The author says they simply asked for a launch ad, and found the style close to Opus 5.5.
Our summary. The author’s own words are in the post above; we do not copy them.
Our note
A launch ad for Drop Notch, which appears to be a Mac app that tracks coding agents from the screen notch. It opens on terminal windows named for codex, claude, copilot and grok, each on a task such as "add offline mode to the feed". A prompt box then sends "make the docs sidebar collapsible" with Cline and "Opus 5" selected, beside icons for Grok, Gemini, OpenCode, Qwen and Cline. Later panels show an "Edit Sidebar.tsx" request with Deny and Allow, an $86.58 analytics chart, a music player and a 24:58 focus timer. It ends on dropnotch.space. No prompt is public, and the model is the author's claim.

Every Screen Agent
An agent finishes a job on a laptop; the result shows up on a phone, then in a terminal, a chat and a code review. A 6.8-second light product shot.
