How to use it

  1. 01

    Add local data

    Paste text or open a file up to 5 MiB. Input stays in this browser and is never uploaded.

  2. 02

    Build the recipe

    Search operations, configure only the needed options, reorder or disable steps, and add an inspection breakpoint.

  3. 03

    Inspect and reuse

    Review every intermediate output, copy or download the result, and save or export a versioned recipe.

Frequently asked questions

Does my data leave the browser?

No. Input, intermediate values, and outputs are processed locally. Only recipes you explicitly save are stored in localStorage.

What happens when one step fails?

Execution stops at that step, shows its exact error, and preserves the output of the last successful step for inspection.

Can I process very large files?

This release intentionally limits text input to 5 MiB to protect browser memory and responsiveness. Use the SQL editor for larger analytical datasets.

Are cryptographic operations a security guarantee?

No. Hashing and encoding operations are deterministic utilities; review keys, protocols, and threat models separately for security-sensitive work.

Keep working with other focused browser utilities.
