Ramble in. Clean text out.

You said "uh" twelve times and misspelled Dave. Lexi doesn't care — it strips the filler, fixes the typos, and delivers polished text before you even notice.

Raw voice

uh yeah so I think we should probably like reach out to Jenny from legal I think she said something about the NDA being like not ready yet or maybe she uh send it, not sure, and um we should cc Davee maybe be sure to update the Q2 um goals slidez before Friday's thing, I forget the link but it's probably in Slack somewhere...

Removed filler Fixed spelling Added to Dictionary
Clean output

Let's reach out to Jenny from Legal — she may have mentioned the NDA isn't finalized yet, or possibly already sent it. Let's also CC Dave. Finally, make sure the Q2 Goals slide is updated before Friday's review. The link should be in Slack.

Your voice does more
than type.

Select text, hold the action key, speak a command. Lexi reads the app you're in, understands what's selected, and does exactly what you asked — no copy-pasting into a chat window.

Gmail — Inbox
Selected text

Hi team, I wanted to follow up on the Q2 roadmap discussion from last week. There are several items that need immediate attention including the API migration timeline, the new onboarding flow designs, and the budget allocation for the infrastructure upgrade. Can we schedule a 30-minute sync this week to align on priorities?
