Start using Codex?","description":"If you want more workflows and tactics to build a business with AI, check out this free workshop: https:\/\/www.ideabrowser.com\/workshop\n\nI sit down with Riley Brown to get a hands-on tour of OpenAI's Codex, which he argues is the most powerful single interface for using AI agents today. Riley walks me through how Codex unifies vibe coding, knowledge work, browser use, computer use, and automations into one app, all running on GPT 5.5. I come in as a complete Codex skeptic who has spent most of my time in Claude Code, and Riley shows me skills, plugins, projects, Remotion, Chronicle, and the in-app browser to make his case. By the end, the question becomes whether the era of separate tools for documents, decks, code, and research is collapsing into a single super app.\n\n00:00 \u2013 Intro\n03:23 \u2013 What is Codex\n06:46 \u2013 Why a GUI beats the terminal for most users\n10:13 \u2013 Codex: the all in one platform\n12:48 \u2013 Atlas browser inside Codex\n14:21 \u2013 Remotion explained and motion graphics workflows\n19:28 \u2013 Computer use and Chronicle\n22:26 \u2013 Plugins, skills, MCPs, and integrations\n31:57 \u2013 Evals, examples, and good outpu\n38:43 \u2013 Hard questions: who Codex is built for\n40:44 \u2013 Browser use plays itself in chess\n43:20 \u2013 Running Claude Code inside Codex\n45:58 \u2013 GPT 5.5 cost and effort settings\n48:50 \u2013 GPT Images 2.0\n54:09 \u2013 Why most people feel overwhelmed by AI tools\n57:09 \u2013 Three projects to start with on day one and Closing thoughts\n\nKey Points\n\n* Codex is positioned as a super app where coding, documents, decks, research, and automations live in one interface, with GPT 5.5 as the underlying model.\n* The trend across Codex, Cursor, and the Claude Code desktop app is the same GUI pattern: chats on the left, agent in the middle, output on the right.\n* Plugins offer official integrations like Slack, Notion, Sheets, Remotion, and Canva, while skills are user-created instructions stored as a SKILL.md file.\n* Computer use and browser use have crossed a speed threshold; the chess demo runs at near-human pace, a leap from earlier \"dial-up\" feeling agents.\n* Running Claude Code inside the Codex terminal lets you stack both subscriptions and use each model where it shines.\n* The biggest unlock for companies is collecting good examples of finished work so agents can match the bar.\n\nNumbered Section Summaries\n\n1. The Codex Premise\u00a0I open with Riley's claim that Codex is the strongest interface for AI agents available today, powered by GPT 5.5, and bundled into any ChatGPT subscription. He frames the episode as a tour of how to do all of your knowledge work and coding inside one platform.\n\n2. One Platform for Code and Knowledge Work\u00a0Riley shows that Codex creates apps, spreadsheets, charts, Word docs, and PowerPoint decks in the same interface, with exports to tools like Canva. He contrasts this with Claude's split between Cowork and Claude Code, which he finds limiting because each surface has separate permissions.\n\n3. Browser Use, Computer Use, and Chronicle\u00a0We walk through OpenAI's Atlas browser folding into Codex, the speed jump in computer use (controlling Canva, exporting files, feeding results back), and Chronicle, a screen-watching memory layer released two days before recording. Riley flags privacy as a real consideration while still recommending people learn what it does.\n\n4. Plugins, Skills, and Automations\u00a0Riley untangles the overlapping vocabulary of plugins, skills, MCPs, and connectors. Plugins are OpenAI-approved integrations like Slack, Notion, Sheets, Expo, Remotion, and Canva. Skills are user-built folders with a SKILL.md file, easy to generate by asking Codex to make one. \n\n5. Models, Costs, and Stacking Subscriptions\u00a0We cover GPT 5.5's pricing (roughly twice the cost of GPT 5.4 via API, around 20% higher than Opus 4.7), effort settings (low, medium, high, extra high), and the trick of opening the Codex terminal, typing\u00a0`claude`, and running Claude Code inside Codex on the Anthropic subscription.\n\n6. Day-One Projects and Closing Advice\u00a0Riley closes with a starter pack: have fun first, build a small game and let browser use play it, run a deep research task into a spreadsheet then a doc and a deck, try a 3D simulation, and pick the most annoying daily task to convert into an automation.\n\nThe #1 tool to find startup ideas\/trends - https:\/\/www.ideabrowser.com\/\n\nLCA helps Fortune 500s and fast-growing startups build their future - from Warner Music to Fortnite to Dropbox.
