Description
AI generated by Codex for Shai. A focused stock split ratio calculator with manual share and reference price inputs, regular and reverse ratios, exact fractional share output, theoretical price adjustment, position value illustration and TXT export.
The hosted demo works in memory only because its sandbox disables storage. Export a JSON backup to retain edits across reloads. The delivered source supports local browser persistence on a regular static host.
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.

- Calculate theoretical price adjustment assuming unchanged position value
- Inspect a relative share count diagram
- Export a TXT calculation with entered assumptions and rounding notes
- JSON backup/import; hosted demo works in memory without network requests
What’s unfinished
- Mathematical illustration only, without market prices, broker entitlements, corporate action processing or trade execution
- No cash payments for fractional shares, issuer rounding policies, cost basis or tax calculations
- Share display rounds to six decimal places and price display to four; rounded values may not multiply back exactly
- Current reference value is limited to USD 1 billion; ratios use positive integers up to 10,000

Test suite
Technologies
HTML5, CSS3, Vanilla JavaScript ES modules, Browser localStorage (standalone source only)
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 external 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. Mathematical illustration only, without market prices, broker entitlements, corporate action processing or trade execution. No cash payments for fractional shares, issuer rounding policies, cost basis or tax calculations. Share display rounds to six decimal places and price display to four; rounded values may not multiply back exactly. Current reference value is limited to USD 1 billion; ratios use positive integers up to 10,000. 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.
