A side-by-side comparison of Hand Wave and sizeless — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Hand Wave
Aadi Sanghvi
Real-time sign language recognition for a webcam or screen share that turns hand signs into text and speech in the browser.
Key features
- Live Camera Recognition: Recognises sign language directly from the device webcam without an install.
- Screen Share Recognition: Runs against any screen share, so signs in a video call can be captioned live.
- Text and Speech Output: Emits the recognised signs as caption text and can speak them out loud.
- On-Device Vision: Model runs in the browser tab — the video stream is not uploaded to a server.
- Zero-Setup Web App: Opens in the browser with two buttons — Start Camera or Share Screen.
- Smart-Glasses Friendly: Designed to work with a phone or smart-glasses camera feed for real-world conversations.
Best for
- Deaf-Hearing Conversations: Sign into the camera and let a hearing person read or hear the translation live.
- Accessible Video Calls: Add a live sign-to-text overlay to Zoom/Meet calls via screen share.
- Live Stream Captions: Twitch or YouTube creators who sign can auto-caption their broadcast.
- Classroom and Meeting Access: A Deaf student or colleague signs, everyone else sees text in real time.
- Assistive Wearables: Pair with smart glasses so signs are turned into audible speech for the person opposite.

sizeless
Turns a smartphone video of an open trench into a centimetre-accurate 3D point cloud, CAD as-built plan and GIS-ready digital twin of buried utilities.
Key features
- Smartphone capture: Field crews record an open trench with a standard iPhone Pro — no specialist scanning hardware and no separate surveying appointment
- Centimetre-accurate point clouds: Reconstruction algorithms developed at ETH Zurich build a high-resolution 3D point cloud of the excavation from the video alone
- Standards-compliant CAD output: Generates as-built plans in DWG and DXF, with couplings and pipe runs identified and measurements simplified
- 3D digital twin and GIS export: Produces a model of the pipe route including building entries that drops into existing GIS systems
- Works without GPS: Captures basement sections and building entry points where GNSS-based surveying fails
- Immediate backfilling: Because capture takes minutes, trenches close right after filming instead of waiting on a survey crew
- Documentation in about 72 hours: Complete records arrive weeks earlier than conventional surveying, enabling prompt connection billing
- Third-party utility capture: Records crossing utilities and as-laid geometry as unbroken 3D evidence, replacing hand sketches
Best for
- A utility network operator documenting residential service connections without booking a surveyor for every site
- A contractor closing a trench the same day instead of leaving it open pending a survey appointment
- Capturing a building entry point in a basement where GPS-based surveying cannot get a fix
- A district heating project producing as-built DWG plans for regulatory sign-off
- Spotting a laying error in the 3D point cloud before backfilling, while the fix is still cheap
- Feeding as-built pipe geometry into a GIS system for long-term network maintenance planning
