Summary
Creator Riley Brown shares his hands-on experience after five days of using Anthropic’s newly released Claude Opus 5.5, calling it fast, cheap, and reliable enough to replace several paid SaaS subscriptions. He demonstrates building a custom internal tool — a hybrid of Notion, a task tracker, and Google Drive — using Claude Code’s new projects feature, and explains how the app took just a few hours and about 20 prompts to build, complete with shareable links and a Figma-style design board.
The video also highlights how Anthropic has begun merging previously separate products, including Claude Code, Claude Cowork’s spreadsheet and document tools, and Claude’s design mode, into a single unified workspace. Brown argues this consolidation, combined with Opus 5.5’s speed and low cost, makes it practical for small teams to “vibe code” lightweight, purpose-built replacements for bloated software like Notion.
The second half of the video shifts to predictions about OpenAI’s upcoming DevDay event, including rumors of a new security-focused model referred to as “GPT Cyber.” Brown frames the event as OpenAI’s expected response to Opus 5.5, arguing that competitive pressure between Anthropic and OpenAI is accelerating the pace of new AI product releases for developers and everyday users alike.
