Word Counter vs Readability Score Calculator
Both tools analyze text, but they answer fundamentally different questions. The Word Counter tells you about *length* — words, characters, sentences, paragraphs, reading time. The Readability Score tells you about *difficulty* — what grade level your writing hits, whether it's easy or hard to read. Most writers need both: one to hit a length target, the other to make sure the writing is actually landing.

Use Word Counter
When you have a length target — a 1,500-word article, a 600-character press quote, a 3-minute podcast script. The Word Counter is your in-browser reality check: are you there yet, are you over, are you dangerously short. No signup, just start typing or paste in.
Use Readability Score
When you're writing for a specific audience or platform. Explaining tax law to first-time filers? Aim for Flesch 70+. Publishing in Nature? Target grade 16. The Readability Score catches vocabulary and sentence-structure choices that feel natural to you but alienate your reader.
Using them together
During drafting, keep the Word Counter open to stay on-target for length. After a first pass, run the text through Readability Score. If the scores come back grad-school-level but you're writing for a general audience, shorten sentences and swap jargon for plain words — then re-check. Iterate until both the length and the difficulty line up with your goal.
