Three tells. One keystroke.
Kills the phrases.
"Happy to help." "Circle back." "I hope this email finds you well." "In summary." Every AI idiom goes. Your meaning stays.
Kills the formatting.
Em-dashes become commas. Unnecessary bullets become prose. Over-bolding gone. Emoji salad thinned. Headings removed from short messages.
Keeps your voice.
SpeakHuman won't rewrite your email. It polishes what's already there. If your draft is already human, it leaves it alone.

Questions.
Does it just rewrite my email?+
No. SpeakHuman surgically removes specific AI tells (em-dashes, 'circle back', triplet cadence, unnecessary bullets, over-bolding) while preserving your voice, facts, and register. If your draft is already clean, we leave it alone.
Will it pass AI detectors?+
In our testing against GPTZero, Copyleaks, and Originality.ai, cleaned output averages under 15% AI-score — down from 80%+ on the input. We're honest about when we can't fully fix a piece (rare, but happens).
How is this different from Grammarly or Quillbot?+
Grammarly rewrites for grammar. Quillbot paraphrases. SpeakHuman does one specific thing: strip the fingerprints of AI writing while keeping your voice. One keystroke, no dialog boxes, no 'rephrase this sentence' overlays.
Is my text stored?+
No. Cleans are processed in-memory and never written to disk. We do not keep your content, train models on it, or share it with third parties.
What if I don't like the output?+
Hit 👎 and tell us why. Every piece of feedback improves the system prompt. We add a regression test for every real failure.
