AirProof AI vs sizeless: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of AirProof AI and sizeless — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
AirProof AI
AirProof AI
AI-powered airflow simulator that finds the best spot for your air purifier in seconds using a physics-informed model.
Key features
- Physics-Informed AI Engine: Runs a real-time airflow prediction model trained on physics rules and room scenarios instead of pure heuristics.
- Instant Airflow Prediction: Move the purifier around a 3D room preview and see updated airflow coverage in seconds without any simulation setup.
- Purifier Brand Presets: Pick your model from Dyson, Xiaomi, Philips, Levoit, Blueair, Coway, Honeywell, Winix, Shark, Rabbit Air, Oransi, and more.
- AI-Trained Room Scenarios: A library of ready-made rooms — standard bedroom, living room, office, plus premium double bedroom, studio, open plan, meeting room, clinic, classroom, and cabin layouts.
- Free Starter Setups: Three standard room setups (bedroom, living room, office) are free after signup so you can validate placement before upgrading.
- Multi-Zone Room Support: Premium adds L-shaped and open-plan rooms with kitchens, lounges, and beds so multi-zone homes get accurate placement guidance.
Best for
- Home Purifier Placement: Homeowners test where to put a new Dyson or Levoit purifier before drilling holes or committing to an outlet.
- Landlord & Airbnb Prep: Property managers optimize purifier placement across bedrooms and living spaces before guest stays.
- Small Office Air Quality: Offices with open workstations visualize coverage to make sure air is filtered near desks and meeting areas.
- Clinic & Classroom Compliance: Vet clinics, meeting rooms, and classrooms use scenario templates to place purifiers where airflow matters most.
- Purifier Purchase Decisions: Buyers compare how different brand models cover the same room before deciding which unit to buy.
sizeless
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
