Tools Lab

Uses the browser's SpeechRecognition API where supported (mainly Chrome). Falls back to an unsupported message elsewhere.

Educational demo only — uses tiny primes, not suitable for real security. Generates a small keypair and lets you encrypt/decrypt a short number.

Educational Diffie-Hellman key exchange visualizer with small demo numbers.

Toy demo: a deliberately tiny (8-bit) hash function, showing how easy collisions are with a small output space (birthday paradox).

Format/checksum validation only — nothing is stored or transmitted.

Format-check only (mod-97 checksum) — does not verify the account exists.

Waiting...

25-minute focus sessions with 5-minute breaks. Distinct from the plain countdown tool above.

A quick local checklist widget — separate from your account's login streak. Stored only in this browser (localStorage).
