AI floor plan from video
Short answer: there is a public example of Gemini 4 Hydrogen drawing a floor plan from a first-person walkthrough video, from a one-line prompt. Google’s model card says Hydrogen accepts video, so you can try the same in AI Studio. We have only this community example, and we have not checked the plan against a tape measure.

What “AI floor plan from video” is
You walk through a space with a phone, give the recording to a model that accepts video, and ask it to draw the layout — walls, rooms, and what it can see of doors and furniture. That is different from text-to-plan generators, and also different from tools that animate an existing floor plan into a walkthrough video.
The community example
Video walkthrough to a floor plan
The author gave Hydrogen a first-person walkthrough video of a home and a one-line prompt asking it to draw the floor plan, then shared a clip of the resulting layout. We have not checked the drawing against measured dimensions.
The prompt the author posted
Copied verbatim from the public post. Attach your own walkthrough when you try it. Do not upload other people’s homes without permission, and strip anything private from the file first.
Honest limits
- One public Hydrogen example is not a product evaluation.
- A video does not automatically give accurate scale. The author did not claim a surveyed measurement, and we do not add one.
- Furniture, mirrors, and poor lighting can hide walls. Expect to correct the sketch.
- The DeepMind model card is the official source that Hydrogen accepts text, images, audio, and video. Source: Google DeepMind, 12 November 2026
How to do it with Hydrogen
Google documents three practical doors. This site has not timed them for these tasks.
Google AI Studio
Sign in with a Google account, choose gemini-4-hydrogen, and paste a prompt (and, where the task needs it, an image or video). Google’s pricing page lists Free Tier input and output as “Free of charge.” Paid use is $1.50 / $7.50 per 1M input/output tokens.
Gemini app
Google says free Gemini app users “will get access to Gemini 4 Hydrogen via auto model selection when it’s the appropriate model for the prompt.” You do not pick the model yourself.
Google Antigravity
Useful when the job is a multi-file project (a game, a Remotion repo, a Three.js app). Antigravity’s models page, checked 14 Nov 2026, lists Hydrogen on the Free & Plus plan; the $0 Individual plan has “basic weekly rate limits.” The 12 Nov launch post still described paid Pro and Ultra subscribers — both official wordings are on the free guide.

Cheaper official models, and specialized tools
List prices below are official vendor pages already cited on this site (retrieved 13 or 14 November 2026). We have not priced third-party apps.
| Option | Official price | When it may fit |
|---|---|---|
| Gemini 4 Hydrogen free tier | Input and output “Free of charge,” rate-limited; free-tier prompts may be used to improve Google’s products | Trying a one-file game, scene, or page in AI Studio |
| Gemini 4 Hydrogen paid | $1.50 input / $7.50 output | When you exceed the free tier or do not want free-tier data use |
| Gemini 3.8 Flash | $0.75 / $3.75 until 31 Dec 2026; $1.50 / $7.50 from 1 Jan 2027. Also on a free tier | Cheaper until the end of 2026; several community posts still preferred Hydrogen’s result on visual/code tasks |
| Claude Sonnet 5.5 | $2 / $10 | A community Three.js robot test judged Sonnet better and more expensive (author figures on the 3D scene page) |
| Claude Opus 5.5 | $4 / $20 | A higher official price; Google did not publish a Hydrogen head-to-head |
| GPT-6.1 Sol | $2 / $10 (≤272K) or $4 / $15 | Another paid alternative; see compare |

FAQ
Can AI create a floor plan from a video?
One public Gemini 4 Hydrogen example did: the author attached a first-person walkthrough and asked, in one line, for a floor-plan drawing. The DeepMind model card states that Hydrogen accepts video. That is not a promise of measured accuracy, and this site has not verified the drawing.
Is this the same as “AI floor plan generator” searches?
Only in part. Many “AI floor plan generator” tools start from text or a 2D image, and that generic search is already crowded. “AI floor plan from video” / “video to floor plan” is the walkthrough job. Some search results for those phrases show the opposite product (a video made from an existing plan).
Can I use this for a listing or a renovation bid?
Not as a substitute for a measured survey or a professional drawing. Treat the first output as a sketch, check every wall yourself, and do not invent dimensions the video does not support.
