Inbox Copilot now drafts replies from your team's past threads

What changed

• Inbox Copilot can now index a workspace's historical sent mail (opt-in, per user) and use it as grounding when drafting a reply, instead of relying only on the current thread.
• Drafts show a short 'based on 3 similar past replies' note with links, so a person can check the sources before sending.
• A new tone slider lets a user nudge a draft from 'brief' to 'detailed' without rewriting the prompt.

Who it helps

The practical problem it solves

Most AI email drafts read the same no matter who asks for them, so people spend as much time rewriting the draft as they would writing from scratch. Grounding drafts in a team's own prior replies keeps tone consistent and cuts the editing step down to a quick read-through.

Ways to try it

• Use it to answer a recurring customer question in the team's established voice in one pass.
• Have a new hire generate a first draft, then compare it against the linked past replies to learn the team's norms.
• Set the tone slider to 'brief' for busy days when replies just need to confirm next steps.
