Riff Check

RiffCheck tells you what you're actually working with before you build on it. Point it at any HuggingFace or Kaggle dataset or model and get an instant readout: license classification, card completeness, and privacy-risk flags - the checks you'd otherwise do manually by digging through dataset cards, license files, and column names. Built for ML researchers, data scientists, and anyone working with datasets and models where getting provenance and licensing right isn't optional. WHAT RIFFCHECK CHECKS • License classification - normalized against SPDX and (Pro) a broader license database, with clear flags for missing, unclear, or non-commercial licenses • Dataset/model card completeness - flags missing sections like intended use, collection methodology, and known limitations • PII risk heuristics - scans for likely personal-data indicators in card text and column names FREE, NO ACCOUNT NEEDED Unlimited checks on any public HuggingFace dataset - no sign-up, no account, no daily limit. Every check saves automatically to your Library, and Batch Check lets you paste a list of IDs and check them all at once. RIFFCHECK PRO • Model checks - the same license, completeness, and PII analysis for HuggingFace and Kaggle models • Kaggle dataset checks • Unlimited daily checks (free includes 3/day on the above) • Compare - check two datasets or models side by side, with a metric-by-metric comparison table • Library - tags (automatic and your own), notes, and folders, with search and filtering • iCloud Sync - your Library stays in sync across iPhone and iPad (optional, off by default) • Sample data preview - see real rows before you commit • PDF, Markdown, CSV, and JSON export • Citation export - APA, MLA, Chicago, IEEE, or BibTeX PRIVACY RiffCheck talks directly to HuggingFace and Kaggle's own APIs from your device - there's no server of ours in between. Your Kaggle credentials never leave your device. Every check is saved locally on-device; iCloud Sync is optional and off by default. No analytics, no tracking.
