See what's weak — rewrite it yourself

The Coach flags specificity, stock transitions, hedging, stance, and topic-sentence gaps. Diagnoses only.

How it works

1

Open Writing feedback

Coach runs on every document alongside grammar checks — independent of AI detection scores.

2

Read the diagnosis

See flagged spans for specificity, stock transitions, hedging, missing stance, or claim-less openings.

3

Rewrite yourself

No auto-rewrite, no paraphrase, no generated replacement text. You revise.

FAQ

No. It diagnoses weak spots and explains why — you write the fix.
