Description

AI generated by Codex for Shai. A focused line-processing utility with a fixed, visible cleanup pipeline: trim whitespace, remove empty lines, deduplicate with optional case folding, natural-number sorting, prefix/suffix affixes, numbering, removal counts, and TXT export.

Editor contents remain in this tab only, on both the hosted demo and standalone source. Export a JSON backup to keep them. No contents are automatically written to browser storage.

Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.

What works

  • Process pasted text up to 200,000 text units and 5,000 lines
  • Trim, remove empty lines, and keep first occurrences when deduplicating
  • Sort with English natural-number comparison or preserve original order
  • Add prefixes, suffixes, and numbering from a chosen starting value
  • Inspect removal counts and select or download cleaned text
  • JSON backup/import; hosted demo works in memory without network requests

What’s unfinished

  • English case folding and sorting; no locale selection, regex, CSV parsing, file import, or rich text
  • Input stays in tab memory only; JSON backups include input text and settings
  • Cleanup has a fixed operation order and does not offer multi-step undo
  • Output downloads are plain LF-separated UTF-8 text

Setup requirements

Unzip source and run python3 -m http.server 8080 in the folder. Open http://localhost:8080 or deploy to a static HTTPS host. No build or API key. Node 20+ runs test.mjs. See README.md and QA.md.

Dependencies and ongoing costs

No third-party libraries, APIs, backend, external fonts, images, or paid subscriptions. Hosted demo is served by SellMyVibe. Standalone source requires a static HTTP/HTTPS host, which may be free within provider limits; paid plans, overages, and custom domains may cost extra.

Known limitations

Working prototype. English case folding and sorting; no locale selection, regex, CSV parsing, file import, or rich text. Input stays in tab memory only; JSON backups include input text and settings. Cleanup has a fixed operation order and does not offer multi-step undo. Output downloads are plain LF-separated UTF-8 text. App data resets on reload in the hosted demo; export JSON backups. See the app description for standalone storage behavior. No independent security audit or broad device/browser certification.
