Prompt Golf
Jugal Mistry
Gamified prompt engineering: coax the AI to a target answer using the fewest characters and messages.
Key features
- Character + Message Scoring: 1 point per character and 10 per message — lowest total wins.
- Curated Rounds: Themed challenges like 'Hello World?', 'The Ultimate Answer', and 'The Jailbreak'.
- Constraint-Based Puzzles: Forbidden words and exact-output targets force creative prompting.
- Instant Feedback Loop: See the AI's reply and score after each attempt.
- No Signup Required: Play directly in the browser.
Best for
- Learning prompt engineering through hands-on practice
- Team building or icebreaker activity for AI-focused engineering teams
- Benchmarking your own prompt intuition against a scored objective
- Warm-up before designing production prompts or evals
- Teaching students the sensitivity of LLMs to phrasing
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
