Our top picks at a glance
Every email tool now claims AI triage. Most of them mean the same thing, a smarter folder. Your inbox gets sorted into piles, and you still have to read the pile marked important and do what it asks.
Real triage has three steps. Read the email, decide whether it needs you, and then handle it. We ranked these tools on how many of those steps they take off your plate, not on how pretty the inbox looks afterwards.
Five of them sort. One of them also does the work.
1. Sidekick Pro
AI agents for your email, calendar, calls and browser
The only tool here that reads every email, decides what needs you, and then acts on it, from drafting the reply to booking the meeting.
Sidekick Pro reads every email in your Gmail and judges it the way an assistant would. The few that need you arrive as an alert on your phone, with one-tap buttons to draft the reply or have it handle the job. The rest wait quietly, and you get a morning brief of what came in overnight.
You teach it in plain words, once. Tell it that a sender always matters, or that a domain never does, and that rule applies to every email from them from then on. It also turns emails into action. A meeting request becomes a calendar event, an ask becomes a task, and an agent can do the follow-up in your browser.
Your inbox is only one channel. Sidekick Pro triages your texts, calls and Slack messages with the same rules, so one assistant decides what reaches you, wherever it comes from.
Other tools sort your inbox. Sidekick Pro empties it.
- Reads every email Judges each message the way an assistant would, not with folder rules.
- Alerts that matter Only the few emails that need you reach your phone, with one-tap replies.
- Tell it once A rule you state about a sender or domain applies to every email that follows.
- Email to action Meeting requests become calendar events, and asks become tasks.
- Morning brief A short summary of what came in overnight and what needs you today.
- One triage, every channel The same rules cover your texts, calls and Slack messages.
What we like
- Triages and then acts, instead of only sorting
- Keeps your current Gmail; nothing new to learn
- Plain-language rules per sender or domain
- Covers texts, calls and Slack as well as email
Keep in mind
- Gmail only for now; no Outlook support yet

From $20/mo
Plus $20/mo · Business $29/mo · Ultra $200/mo
Best for: Busy people on Gmail who want the inbox handled, not just sorted.
Best morning brief
2. alfred_
AI email and calendar assistant with an overnight brief by alfred_
A focused assistant that triages your inbox overnight and hands you a short brief of what needs you, with drafts ready.
alfred_ works through Gmail and Outlook. Overnight it sorts your inbox, pulls out tasks, and writes draft replies in your voice. In the morning you get a brief of the few things that need your judgment.
It never sends anything on its own. You review and send every message, which is safe but keeps you in the loop for every reply. Most of its work happens in its own app rather than inside your email.
What we like
- Clear overnight brief and draft replies
- Works with Gmail and Outlook
- One flat price with every feature included
Keep in mind
- Email and calendar only
- A newer product with a smaller track record
- Price

Best set-and-forget filter
3. SaneBox
Email filtering that works in any email app by SaneBox
The veteran of inbox filtering, working quietly in any email app, but it sorts by sender and habit rather than by what an email says.
SaneBox runs on its own servers and moves unimportant mail into folders such as SaneLater, so it works with Gmail, Outlook, iCloud and any other IMAP account, in whatever email app you already use. It learns from where you move messages.
That design is also its limit. It decides by sender and your past behavior, not by reading the email, and it does not draft replies or act on anything.
What we like
- Works with almost any email provider and app
- Low price and no new app to learn
- Mature, reliable filtering
Keep in mind
- Sorts by sender and habit, not by content
- No draft replies or follow-up
- Price
- Snack $9.49/mo · Lunch $15.99/mo · Dinner $42.99/mo · less billed yearly · 14-day trial

- Any email app
- Best for
- People who want less noise in any email app, with no setup after the first week.

Fast, keyboard-first email app with AI by Superhuman

AI-native email app for Gmail by Shortwave
A smart AI email client built for Gmail, with strong search and summaries, but it has dropped its free plan.

6. Spike
Chat-style email app with a Priority Inbox by Spike
A friendly, chat-style email app with a Priority Inbox and a real free plan, but lighter AI than the rest.
Spike shows email as conversations, like a chat app, and adds notes, tasks and team chat. Its Priority Inbox sorts messages into Priority and Other, and its AI can summarize, suggest replies and translate.
The free plan is generous for one address. The AI is a helper rather than a triage engine, and the chat format is a matter of taste.

- Works with Gmail, Outlook and other providers
- Chat, notes and tasks in one app
Keep in mind
