Text Tools

Transform and inspect plain text locally in the browser.

Text Tools is a standalone local-first application in the add·ideas Toolbox. Inputs are processed in the browser and are not uploaded.

Version 0.1 scope

• Ordered pipelines for line endings, trimming, whitespace, stable sorting and deduplication
• Locale-aware case conversion, Unicode NFC/NFD/NFKC/NFKD and best-effort Latin transliteration
• JSON/HTML/URL/Base64/hex escaping, wrapping and delimited-column selection
• Explicit UTF-8, UTF-16LE and Latin-1 file decoding plus text/code-point/line inventory
• Versioned JSON recipe import/export and per-step size/change reports

Pipelines are limited to 2,000,000 UTF-16 input units and an 8×/32 MiB output expansion. File input is limited to 16 MiB before decoding. Encoding is selected explicitly rather than guessed; compatibility normalisation, transliteration, narrow encodings and several transforms can be lossy, so source, result, and warnings remain visible. See docs/ARCHITECTURE.md and docs/PRIVACY-SECURITY.md.
