Yes. An AI inbox triage assistant reads every new email, files newsletters, follow-ups and CC chains into a daily digest, drafts replies in your voice, and texts you the one or two emails that need a real decision. Sabi does this for Gmail, Outlook and Microsoft 365, and sends nothing until you approve it.

Inbox triage is sorting by decision, not by folder. The assistant reads each new message, decides whether it needs you, needs a reply she can draft, or needs nothing, and treats each class differently.
Newsletters, follow-ups and CC chains go into a daily digest you skim once. Replies she can handle are drafted and parked for your approval. The rare message that needs your judgment is surfaced on its own.
Sabi texts a 5-line morning summary of your inbox: what needs a reply, what to ignore, and what is on fire.
Gmail, Outlook and Microsoft 365 connect through OAuth with one tap, so the assistant never sees your password. Yahoo, AOL and other custom IMAP accounts connect as well.
The connection is yours to end. Disconnect from inside Sabi at any time, or revoke the grant from Google directly, and the access stops.
Sabi connects Gmail, Outlook and Microsoft 365 through a one-time OAuth grant and never sees your password; Yahoo, AOL and other IMAP accounts connect too.
They will if the assistant has studied your writing first. Ask Sabi to "learn my brand voice" and she reads what you have already written, picks up your tone and your common scenarios, and drafts in that voice.
The first week, read every draft. Once the drafts stop needing edits, you can let her send routine replies on her own and keep the gate only for the ones that matter.
Sabi learns your tone from what you have already written and drafts replies in your voice, and once you trust her you can let her send automatically.
Yes, and it should be the first thing you set. Tell Sabi "always draft, never send without me" and an approval rule holds every outgoing email and text until you say yes to each one.
The gate is written in code, not a prompt the model tries to remember, so it does not depend on the model keeping an instruction in mind. Without a rule she sends what you ask her to send or schedule. Slack and Discord messages are not covered by approval rules yet.
Sabi's approval gate is written in code and stops her from emailing or texting anyone until you approve each message.
SaneBox, Fyxer and Serif are inbox tools: they sort, filter and draft inside the mailbox. An assistant treats the inbox as one of several jobs.
When an email asks for a meeting, Sabi negotiates the time and books it. When a lead replies, she logs it and schedules the follow-up. The same thread that triages your email also runs your calendar, follow-ups, content and reports.
Sabi is an assistant that triages the inbox and also runs your calendar, follow-ups, content and reports, where SaneBox, Fyxer and Serif stop at the inbox.

Yes, triage requires reading each new message. Your data lives in the United States on SOC 2 compliant providers, encrypted in transit and at rest, and the AI providers that run Sabi do not train on your content. Any staff access is recorded in an access log.
They go into a daily digest instead of your main thread. You skim the digest once, and nothing in it is deleted or lost; it is simply out of the way of the emails that need you.
Yes. Sabi works over iMessage or SMS, in the web chat at meetsabi.com, and in the iPhone and Android apps. A voice memo you text her is transcribed, so you can dictate the reply to a flagged email.
Yes. Sabi also works in Slack, Discord and email. Messages sent in Slack and Discord are not covered by approval rules yet, so set the gate for email, where it applies.
