Screenify Studio vs sizeless: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Screenify Studio and sizeless — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Screenify Studio
Brjan
macOS screen recorder that adds 3D cinematic camera moves, device mockups and fully on-device AI captions, voiceover and background removal.
Key features
- 3D Cinematic Camera: 30+ camera templates covering dolly, pan-tilt, orbit and crane moves, with unlimited keyframes, bezier camera routes and three camera modes on a real timeline.
- Smart Auto-Zoom: Detects clicks, typing and mouse dwell to zoom in on the moment automatically, with 24 callout bubble styles and automatic positioning so no manual keyframing is needed.
- On-Device AI Captions: Whisper running through Core ML produces word-level karaoke subtitles at a claimed 98%+ accuracy with real-time preview, entirely offline.
- AI Translation: One-click subtitle translation into 50+ languages with SRT and VTT export, also computed locally on the Mac.
- AI Voiceover: Zero-shot voice cloning from a three-second sample produces narration in 30+ languages across 54 voices, mixed against the original audio and music in a studio mixer.
- AI Background Removal: The Apple Neural Engine strips the webcam background in 5-20ms per frame and replaces it with blur, a solid colour or a custom image with no cloud round-trip.
- 3D Device Mockups: Drop any capture into a photoreal iPhone, iPad or Mac body — multi-device scenes, cinematic angles, slow orbit and real bokeh, flat or fully 3D.
- CLI and MCP Automation: `screenify record <url> --ai` points the tool at any web app and an agent clicks through the described flow, even behind a login, exporting GIF, MOV or MP4 in a single pass; every command returns JSON and an MCP server plus Claude Code skill are included.
Best for
- Launch Day Demos: Produce a feature demo for Product Hunt or X with 3D camera work and auto-zoom in about fifteen minutes instead of a weekend in a timeline.
- Build-in-Public Clips: Record a daily progress clip with camera picture-in-picture and a cinematic move, and post it the same lunchtime.
- Bug Walkthroughs: Capture a single window with callout glow and on-screen keystrokes to show a colleague exactly what changed.
- Localized Product Videos: Generate captions once, then translate them into dozens of languages on-device to ship the same demo to international markets.
- Narration Without Recording: Clone your voice from a short sample and generate a voiceover from a script when re-recording audio is impractical.
- Agent-Generated Demos: Let an AI coding agent invoke the CLI over MCP to film a regression flow or onboarding path automatically as part of a release checklist.
- App Store and iOS Assets: Record the iOS Simulator zero-bezel across 47 device frames, including Dynamic Island, for store listings and marketing pages.
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
