Readability Improver

How Readability Improver works

Find long sentences, passive voice and jargon in your writing. Deterministic rules flag what to fix — no AI, no guessing, same result every time. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

Deterministic rules, not a model

The analyser counts sentences longer than 22 words, detects passive constructions with a simple verb pattern, and checks against a fixed list of jargon words such as “facilitate”, “utilise” and “methodology”.

Because the rules are fixed, the same text always produces the same result — which is what makes it useful for tracking a revision rather than guessing at one.

What each finding means

Long sentences are the easiest thing to fix and the most tiring to read. Passive voice hides who did the action. Jargon signals writing aimed at a peer group rather than a reader.

None of these is automatically wrong. A legal clause may need passive voice and precision; the tool flags, you decide.

Why it is not an AI rewriter

It does not rewrite your text. A model that did would produce different output each run and could change meaning; this page reports what to fix and leaves the writing to you.
