Comparison

A chatbot rewrites.
A proofreader accounts.

Pasting a ministry letter into a chatbot trades control for convenience: the text leaves your perimeter and comes back different, with no record of what changed or why.

This compares a proofreading engine with a general assistant. They are different tools, and the point is knowing which job you are doing.

The distinction

Institutions need an audit trail, not an oracle.

A chatbot cannot tell you which rule it applied, whether it will apply the same rule tomorrow, or why the rewrite quietly changed a legal nuance. WriteX shows the error, the category, the rule, and the fix, and your linguists can tune all of it.

  • A rewrite you cannot diff is a rewrite you cannot approve.
  • Pasting a ministry letter into a public chatbot is a data decision, not a writing one.
  • "Improve this text" cannot be reported on; error counts per category can.

Morphology

Morphology rule, stated and auditable: the sound plural is preferred for this pattern in formal writing.

Choose WriteX if

The text has to be correct, explainable, and yours.

Every change is classified, justified by a rule, and confined to the span that was wrong. Nothing leaves your network if you do not want it to, and the numbers roll up for whoever is accountable.

See the technology

Reach for a chatbot when

You are drafting from scratch, brainstorming, or summarizing, and no one needs to audit what changed. Many teams draft with an LLM and then run WriteX as the gate.

Settle it yourself

Do not take our word for it.

Run a paragraph through a chatbot and through the checker on this page. One hands back new text; the other hands back a list of errors with the rule behind each one.

Frequently asked questions

Can WriteX and an LLM work together?

Yes, and they often do: teams draft with an LLM, then run WriteX as the compliance and correctness gate before anything is published or sent.

Is WriteX itself an LLM?

No. It is Lisan's own Relay Architecture: 32 specialised language components chained together, which is why it responds in real time, explains each correction, and can run on your own servers.

Chatbots keep improving. Will this gap close?

Their language quality improves, but the structural differences do not: a generative model still rewrites rather than classifies, still cannot promise the same output twice, and still runs on infrastructure you do not control.

Every word your institution writes, checked.

Official letters to social posts, Arabic and English alike. One assistant that proofreads, enforces your style, and explains every correction, wherever your teams write.
