Prompt Bridge vs sizeless: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Prompt Bridge and sizeless — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Prompt Bridge
Prompt Bridge
Free Chrome extension that captures your AI chat context and injects it into any other AI platform in one click.
Key features
- One-Click Capture: Save the full conversation from ChatGPT, Claude, Gemini, Grok, Copilot or DeepSeek with a single button.
- Smart Compression: An AI summarizer condenses long chats into tight context blocks, cutting token cost when re-injecting.
- Instant Bridge Inject: Paste your saved context into any other AI's input box in one click, without manual copy-paste.
- Auto Platform Detection: Recognizes the active AI site on tab switch and adjusts capture/inject actions without setup.
- Local-Only Storage: Conversations are kept on your device — no servers, no cloud sync, no telemetry.
- Multi-Browser Support: Ships as a Chrome Web Store extension and works on Chrome, Edge and Brave.
- Zero Sign-Up: Installs and runs without an account or configuration.
Best for
- Cross-Platform Research: Continue a long ChatGPT thread inside Claude or Gemini without losing the accumulated context.
- Model Comparison: Feed the same conversation into different LLMs to compare answers on identical setups.
- Token Cost Reduction: Compress a long chat before re-injecting so you don't pay to replay the full history.
- Privacy-Conscious Workflows: Move sensitive discussions between AIs while keeping the transcript exclusively on-device.
- Team Handoffs: Share a compressed context block with a teammate so they can pick up an AI conversation from a fresh session.
- Multi-Model Coding Loops: Draft with one model, refine with another, and let context travel along instead of re-typing.

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
