Compare carefully.
Keep a record of your inquiry.

Two texts, named numerical methods, and a notebook that keeps your sources, hypotheses and observations distinct.

Measure · compare · inspect

One comparison. Explicit choices.

Compare two original inputs under the same regional table, spelling policy and selected methods. The engine uses exact integer arithmetic. Your entered text stays in this browser.

Numerical measurement. Equal totals do not establish identical text, shared meaning, historical intention or a scientific result. Unmapped characters remain visible. CSV is a summary; JSON contains the complete per-character audit and source-policy hashes.

Maximum 2,000 Unicode characters per text. Inputs are preserved exactly; equivalent forms are folded only when you choose the named policy.

Method labels are QuranML descriptions. The full calculator provides historical-source links, method identities and individual letter contributions.

Your questions · your working record

Give an idea room to be tested.

Record a question, link its sources, state a hypothesis and distinguish it from what you observed. This notebook is separate from your verse notes. No account, model or server receives your writing.

Personal research. Source links and status labels are supplied by you; QuranML does not verify or endorse them. Anyone using this browser profile may read saved notes. Save explicitly, then download a backup to move between devices.

Imports merge up to 100 entries from this research-notebook format, maximum 256 KiB. A conflicting entry stops the entire import. Verse notebooks use a different format and remain separate.
