What this video is
⚡ a 8-minute video, readable in 60 seconds

This video is a compilation of 15 separate builds other creators made with an AI tool called Astra (GPT-6), not a single system the presenter built himself. Per the video's own framing, Astra also researched, scripted, and edited the video, with ElevenLabs providing the voice, HeyGen the avatar, and Seedance the generated footage, while Duncan Rogoff says he directed and reviewed the result; the source treats this as the video's own claim rather than something independently verified. The clearest example of a system already running in daily use is Ethan Mollick's personal wiki: Astra ingested his emails, writings, and calendar over five days to build a multi-gigabyte knowledge base, and it now runs twice a day, cross-referencing new emails against that base and sending him a summary of what needs attention. The other examples, credited to named creators like AI Sampson, Pietro Schirano, Roberto Nickson, and Sharif Shamim, are one-off demos showing websites, 3D reconstructions, and games built with Astra rather than tools used day to day.

Framing: [00:19] the presenter says the video will show 15 examples of what people are building with Astra, what went into each build, and what viewers can take from it.
Key takeaways
+ 39 more takeaways
  • Technique - Duncan's pilot workflow: [08:08] try a short pilot first.
  • Technique - Duncan's pilot workflow: [08:10] lock the narration, plan the shots around the words, and review the edit.
  • Technique - Duncan's pilot workflow: [08:14] then use that approved structure for the next episode.
  • Prior build referenced: [08:17] Duncan Rogoff used GPT-6 Astra to build a playable zombie game called Last Outpost in under an hour, in an earlier episode.
  • Example 1 - AI Sampson: [00:26] shared an animated LOOMERE polo shirt website where the product drives the entire design.
  • On-screen prompt content for LOOMERE (paraphrased in source, not a verbatim quote): [00:38] specifies celadon sage, warm ivory, and pine ink colors, Cabinet Grotesk and Inter Tight fonts, one red accent, a coral thread becoming the polo, four pastel variants, six chapters, a preorder modal, a knot logo, and a fabric-facts marquee.
  • Example - Pietro Schirano: [01:20] built an iPod interface that controls Codex.
  • Build detail: [01:22] Astra built an iPod model in Blender and connected a Mac app to Codex threads.
  • Build detail: [01:27] the click wheel moves through the menu and opens a conversation.
  • Technique from Pietro Schirano's build: [01:39] choose one main action for your app, then ask Astra for an interface that makes that action satisfying to use.
  • Example - Roberto Nickson: [01:47] supplied nine photographs of his studio and used Astra to recreate the space as an explorable 3D model.
  • Suggested use case: [01:58] the studio model is suggested as useful for venue presentation, studio planning, or room layout.
  • Technique from Roberto Nickson's build: [02:02] start with overlapping photos from several positions, ask for an explorable reconstruction, then check its proportions against the real room.
  • Example - Sharif Shamim: [02:09] turned reference images into an architectural flythrough of San Francisco's Palace of Fine Arts.
  • Sharif Shamim's prompt (paraphrased in source, not verbatim): [02:14] asked Astra to research reference images, build an accurate Palace of Fine Arts scene, render a 30-second flythrough that feels real, and use a supplied lighting photo excluding the married couple in it.
  • Reference material: [02:18] Frank Morton Todd's Story of the Exposition is cited as the most complete architectural account of the Palace of Fine Arts.
  • Reference material: [02:18] Astra researched additional references, including an architectural document with the column dimensions.
  • Quantified historical detail: [02:20] the curved building sheltering the picture galleries was about 950 feet long, about 135 feet wide, with a floor area of 126,208 square feet, and 48 feet high to the peak hinges of the steel frames.
  • Quantified historical detail: [02:20] the peristyle ran in a crescent along the Lagoon edge with a 209-foot gap behind the Rotunda, and its smaller columns stood 47 feet 5 inches overall.
  • Verification step shown: [02:22] Sharif Shameem presents an actual research collage as reference before showing the rendered scene.
  • Verification step shown: [02:26] the comparison covers the reliefs around the building and the reflections across the water.
  • [02:29] Sharif also steered parts of the process alongside Astra's execution.
  • Technique from the Palace of Fine Arts build: [02:34] ask Astra to show its references and intermediate renders so a wrong proportion can be caught before it becomes the final shot.
  • Example - Peter Gostev: [02:44] used six Van Gogh paintings to build a walkable world with Astra.
  • Stack detail: [02:47] Astra built it with Three.js, which puts three-dimensional graphics in a webpage.
  • Example - Leon Lin: [03:06] built a forest scene with Astra, Three.js, and custom shaders, reporting about 5 hours of build time.
  • Technique: [03:19] for depth, specify what should be visible in the foreground, middle distance, and background.
  • Example - Ashbytes: [03:29] used Astra to create Human Atlas, an interactive anatomy website with more than 2,000 modeled pieces.
  • Example - Matt Wolfe: [03:57] built an interactive planet simulator called Orbeez by asking Astra for a beautifully designed website that would impress him.
  • Limitation: [04:11] the planet simulator is described as a demonstration of interactive design, not a validated scientific model.
  • Example - Matthew Berman: [04:23] built a city-building game called New Haven using a five-day goal with direction on the result.
  • System in daily use - Ethan Mollick's personal wiki: [06:19] Astra chose the software and strategy itself, then worked five days straight to build a multi-gigabyte personal wiki without further intervention.
  • Wiring: [06:25] twice a day the AI goes through his emails, cross-references them with the knowledge base, and sends him a summary of things to pay attention to.
  • Technique for a personal wiki: [06:32] start with one project folder and ask for linked pages with references back to the original files.
  • Example - AI Samson: [06:39] used Astra-powered 3D jutsu to create a rough scene of an owl flying through a castle to establish the camera path and motion.
  • Wiring: [06:48] exported the rough scene and passed it to a video model, Seedance 2.5, to generate the detailed final cinematic shot.
  • Technique for a difficult shot: [06:58] work out the movement first with a rough reference, then use it to guide the final video generation.
  • Example - Anshu: [07:06] built Afterlight, a browser game scene, connecting Codex to Blender and generating concept images first, then having Astra iterate by comparing in-game screenshots against the target art style until they matched.
  • Example - Tom Krcha: [07:31] shared Steam Atlas, an interactive train display built with Astra using TypeScript and Three.js, with models generated entirely from code and no imported model files.

PROMPTThe Palace of Fine Arts flythrough prompt
okay. new task. your task is to create a palace of fine arts scene. look up as many reference images of the palace of fine arts as possible. create the scene to be as accurate to real life as possible. then render a 30 second flythru of the scene. make it *feel* like real life. focus on the details. i like the lighting in this image. (ignore the married couple I obviously do not want them in the scene).

QUOTEEthan Mollick's GPT-6 knowledge-base post
An example of useful knowledge work: I assigned GPT-6 to read through tens of thousands of my emails, my writings, my calendar appointments and more to assemble a personal knowledge base of research, contacts, ideas, relationships, and tasks over my recent career. [...] downloaded the appropriate software, figured out a strategy, and built a multi-gigabyte personal wiki without any further intervention from me [...] over the course of five days of uninterrupted work. - Ethan Mollick

How this brief was shaped: Personal AI Build / System Demo · confidence Medium

The narrator walks through 15 separate AI-built outputs (websites, architecture flythrough, games) made with GPT-6 Astra, and the OCR shows a verbatim on-screen prompt used to generate the Palace of Fine Arts scene, which is the defining signal for this lens over a generic showcase.

The lens sets this brief's structure, never its facts — every claim is held to the same citation and fact-check standard.
