Small tools.
Big relief.

A lab that builds the tiny utilities everyone needs and nobody makes well. Advanced technology, made approachable. Runs in your browser.

Unix Timestamp
JSON Formatter
Base64 Codec
PDF to Text

Technology should be invisible

You open a new tab to convert a timestamp. You Google "base64 decode online". You paste JSON into a random site. You've done each of these a thousand times. Each time costs thirty seconds and breaks your focus.

We build the tools that should have existed by default — precise, fast, and private. Every tool runs entirely in your browser. No data is ever sent anywhere. No cookies. No tracking. Just the tool, doing its job.
