About Educators101

Students and teachers face enough complexity without their tools adding to it. Educators101 exists to provide a reliable set of free academic utilities that simply work — no ads interrupting your workflow, no account walls, and no data harvesting.

Every tool on this site is built to solve a specific, real problem: helping a student figure out what grade they need on a final exam, enabling a teacher to fairly pick a student at random, helping a writer check whether their essay is readable for their target audience.

All tools run entirely in your browser. When you paste your essay into the Word Counter or type flashcard answers, that text never leaves your device. When you use the Flashcard Maker, your cards are saved locally in your browser — not on our servers.

GPA & Grade Calculations — Our GPA calculator uses the standard 4.0 and 4.3 grade point scales as defined by the American College Testing (ACT) standards. The final exam score formula is derived from standard weighted average mathematics.

Readability Formulas — Reading level scores use the published Flesch Reading Ease formula (Flesch, 1948), Flesch-Kincaid Grade Level formula (Kincaid et al., 1975), and Gunning Fog Index (Gunning, 1952) — the same formulas used by Microsoft Word and academic publishers.

Citation Formatting — Citation metadata is retrieved via the CrossRef API — the authoritative DOI registry used by over 15,000 publishers. Citation formatting follows APA 7th Edition (2020), MLA 9th Edition (2021), Chicago 17th Edition (2017), and the Anglia Ruskin Harvard style guide.

Fraction Arithmetic — Fraction calculations use the GCD algorithm (Euclidean algorithm) for simplification and LCM for common denominator finding — standard mathematical procedures taught in all secondary curricula.
