Frequently Asked Questions

What writing tools does Studylio offer?

Studylio offers a word and character counter, reading time estimator, essay feedback tool, readability score checker, case converter, passive voice detector, Pomodoro timer, and deadline calculator — all free and browser-based.

Is the word counter accurate?

Yes. The word counter splits text at whitespace and counts tokens in real time. All processing happens in your browser; no text is sent to a server.

Can the essay grader replace my teacher?

No. The essay feedback tool provides algorithmic estimates based on measurable writing metrics. It cannot evaluate argument quality, originality, or subject matter knowledge. Use it as a self-improvement aid alongside human feedback.

How is readability calculated?

The readability checker uses four standard formulas: Flesch Reading Ease, Flesch-Kincaid Grade Level, Gunning Fog Index, and SMOG Index. These are based on sentence length and word complexity.
