Frequently asked questions

Common questions

What does the writing voice analyser measure?

It looks at tone, sentence rhythm, vocabulary, readability, paragraph structure, and recurring devices such as questions, lists, first-person language, and rhetorical contrast.

How much writing should I paste?

Use at least 100 words from one finished piece. A complete newsletter or blog post usually gives the clearest picture of your natural writing voice.

Do I need a Letterflow account?

No. The analyser is free to use without an account or payment details.

Does Letterflow store my writing sample?

No. The public analyser processes your sample to create the report and does not save the pasted writing or the result to Letterflow's database.
