How it works

From first draft to a clearer next step.

Inspect the writing. Explore another version. Keep the final decision yours.

Read the signals. Keep the context.
  1. 1

    Paste your text.

    Add at least 5 words in English or Ukrainian. Under 50 words, results are experimental and less reliable. Keep the original context.

  2. 2

    Run the analysis.

    Textumi checks writing patterns and places the result beside your text. The original is never replaced.

  3. 3

    Explore the evidence.

    Switch between the overview and passages. A high signal suggests patterns to review; it does not identify the author.

  4. Open AI Detector
Before you begin

A few useful boundaries.

Better context makes a result more useful. More certainty in a number does not make it proof.

Text length
Start with at least 50 words. Detection accepts up to 12,000 characters. Human-style accepts 50–2,000 words in English and up to 1,000 in Ukrainian; every 250 words use one rewrite.
Languages
The interface supports six languages. AI Detector and Human-style support English and Ukrainian.
Saved work
Results stay in your private history for 30 days. Delete completed requests whenever you choose.

Your interface language and your text language are separate settings.

A signal needs context.

Textumi’s score is an uncalibrated signal, not a percentage of AI authorship. Human writing can be flagged, and AI writing can be missed. A rewrite can still be detected by other services.
