Contest & Giveaway Comment Winner Picker
Run a fair, transparent giveaway draw: paste comments, filter duplicates and @mentions, pick up to 5 winners plus alternates with cryptographic randomness.
Format: @author: comment — the author (before :) is entered, not tagged friends. Bare @handles also work. Tip: export comments to CSV and paste the username column.
Fairness: draws use crypto.getRandomValues with rejection sampling (no Math.random bias), without replacement. Everything runs locally — entry lists never leave your browser. Screenshot the certificate when announcing.
How to Use the Giveaway Winner Picker
Paste your entries
Paste comment usernames or full comments, one per line. Apply filters: dedupe users, require friend @mentions, or require a keyword/hashtag.
Draw with crypto randomness
Watch the animated shuffle, then winners are picked with crypto.getRandomValues — provably uniform, without replacement.
