Murfy vs sizeless: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Murfy and sizeless — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Murfy
Murple
An AI-native online LaTeX editor and Overleaf alternative with unlimited free collaborators, AI paper review, and automatic compile-error fixes.
Key features
- AI Paper Review: Eight simulated readers go through the draft and three models cross-check each other's findings, returning the critique a venue would write without the accept/reject verdict.
- AI Compile Error Fixes: Reads the LaTeX error log and presents the correction as a diff you can accept or reject, instead of leaving you to decode the red output.
- Unlimited Free Collaborators: Every plan, including the free Starter tier, allows an unlimited number of co-authors with no per-seat pricing.
- Real-Time Co-Editing: Multiple authors edit the same paper simultaneously with comments and track changes, without version conflicts.
- Fast Compilation: Claims roughly 2x faster compiles than Overleaf, with a 30-second timeout on the free tier and 5 minutes on Pro.
- Diff-Based AI Suggestions: Every AI-proposed sentence change is surfaced as an accept-or-reject diff so the author's voice is preserved.
- Full Version History: Roll back to any earlier point in the document; Starter keeps 24 hours of history and Pro keeps the full record.
- Template Library: Start from conference, journal, or thesis templates rather than building a preamble from scratch.
Best for
- Multi-Author Paper Writing: Coordinate a research group on one manuscript in real time without paying per collaborator.
- Pre-Submission Review: Run an AI paper review before submitting to a conference or journal to catch unsupported assumptions and missing related work.
- Debugging LaTeX Builds: Resolve undefined control sequences and other compile failures from a suggested diff instead of reading the log.
- Thesis Preparation: Write a dissertation from a thesis template with full version history and rollback across months of drafting.
- Migrating from Overleaf: Move a lab off per-seat Overleaf pricing to a free tier with unlimited collaborators and faster compiles.
- Overnight Change Tracking: Catch up on co-author comments and edits through a morning briefing rather than hunting through the document.
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
