The setting
makes , an email app that works with Gmail and Outlook. It uses AI to draft replies in the user's voice and to sort incoming messages, for individual professionals and sales teams.
Checking a draft against its thread offers factual help at the cost of another interruption before sending.
Dates and prices deserve scrutiny, but ambiguous agreements make confident warnings difficult to justify.
Who you’d be doing this for
“I nearly sent the old fee again. I had to scroll through six replies to find the number we'd actually agreed.”

What is at stake
Reviewers found factual conflicts in 19 of 120 client email threads. You choose what a new check should judge and how to prove it helps.
Why it isn’t already fixed
Every obvious fix costs something else. That’s the part you’d have to decide.
- conflict recall vs interruption burden
- explicit agreements vs ambiguous negotiations
- offline precision vs fewer sent mistakes
- automatic detection vs deliberate invocation
Why Superhuman
AI drafts replies in a user's voice, while the proposed capability judges whether those fluent replies still match the conversation.
