Tools
Self-contained utilities for code, data, and careful hand-offs. Most run entirely in your browser. ShareX stores ciphertext for up to 24 hours and never receives the decryption key.
Playgrounds
Interactive runtimes and system simulations that make code and data flows inspectable in your browser.
PII Removal
Simulate a privacy proxy for banking agents: review locally detected PII, inspect the anonymized document a hosted LLM would receive, and restore its structured response in your browser.
TypeScript Playground
Write, type-check, compile, and run TypeScript in the browser. Powered by CodeMirror 6, the TypeScript language service, and a native Web Worker.
Postgres Playground
Run SQL against a real Postgres database in the browser. Powered by CodeMirror 6 and PGlite (WebAssembly).
Node.js Playground
Install npm packages and run TypeScript/JavaScript in the browser. Powered by CodeMirror 6, almostnode, and Ghostty.
Secure Hand-off
Move a secret to exactly one person, then leave nothing behind.
ShareX
Encrypt a secret in your browser, copy a one-time link, and let one recipient reveal it before the ciphertext is deleted.
- encrypted in your browser
- the key never reaches the server
- one reveal, then deleted
