Browser-based by design
Most TextoLab tools run locally. This makes everyday analysis fast and avoids uploading tool text when remote processing is unnecessary. Normal page requests still reach the hosting infrastructure.
How it works
How TextoLab Works
Choose a tool, add your text, and receive an understandable result directly in your browser.
Deterministic utilities
Counters, readability formulas, keyword frequency, duplicate detection, comparisons, case conversion, whitespace cleanup, and time estimates follow explicit repeatable rules. The same text and settings produce the same result.
The AI Detector uses several signals
The detector combines sentence variation, vocabulary patterns, repetition, structure, transitions, punctuation, and paragraph behavior. No ordinary characteristic decides the score alone. Findings explain influential patterns.
Multilingual reports
English, Brazilian Portuguese, and Spanish have localized routes, interfaces, transition vocabularies, and appropriate readability assumptions.
Explanations before verdicts
TextoLab describes what was measured and its limitations. The AI Writing Score is a pattern indicator, never proof of authorship.
