Records are captured from live game demos with a headless browser and verified with OCR, which is why fields like RTP variants and paytable economics exist here and nowhere else. We are a data company: we run no games and take no bets.

A free browser-only validator for structured AI output used in n8n workflows. Paste sample JSON to check fields, action and target allowlists, confidence thresholds, and human-review routing before an automation action. Everything runs in the browser tab; the tool does not call an AI model, connect to a live n8n workflow, or execute external actions. It applies deterministic checks, not a security certification or production-safety guarantee. Built with AI assistance; use synthetic data and review results before production.

MetWipe is a free, browser-based privacy utility that inspects, removes and verifies metadata in common file types: JPG/PNG/WebP images, MP3/WAV audio, and DOCX/XLSX/PPTX documents. The workflow has four steps — inspect metadata structure, flag privacy-relevant fields, remove supported metadata, and re-scan the cleaned output to confirm removal. Processing happens entirely on-device in the browser, with the vendor stating files are never uploaded to a server, and JPEGs are stripped losslessly to avoid extra recompression. The tool is explicit that a clean metadata score is not a security guarantee: visible or spoken personal information embedded in the file's actual content (faces, addresses, documents, landmarks) is not removed and must be reviewed separately before sharing.

LiuNengAI's Debug Report Builder is a free, single-page HTML tool that helps developers and students turn a messy bug into a well-organized report. Guided fields collect the environment, reproduction steps, the actual error, expected behavior and any fixes already attempted, then the tool formats everything into clean Markdown that can be copied or downloaded as a .md file. All generation happens locally in the browser — the page states there is no upload interface, tracking script or local storage — so no account or server round-trip is required. The page is a single HTML file that can be saved for offline use, and its source is published under an MIT license.
