Best AI Executive Assistants (2026): 10 AI-Powered Assistants for Work Compared

TL;DR

An AI executive assistant is software that takes the administrative half of an assistant's job off your plate: it sorts and drafts email, plans and protects your calendar, prepares you for meetings and follows up on what you promised. For a team or a company, the best AI executive assistant in 2026 is Sentra Agent, because it is built on Sentra's organization memory and already knows what was decided in the meetings, threads and docs you can see, so you never have to brief it. It texts you first with what you owe and what changed, does the work in its own browser, and waits for your yes before anything is sent, booked or posted. For one person who needs help only with an inbox or a calendar, Fyxer, Superhuman, Motion and Reclaim are strong single-purpose choices. Prices were checked on each vendor's site on 19 October 2026.

What an AI-powered executive assistant should do

A human executive assistant does clerical work, such as triaging mail and booking travel, and work that depends on knowing what is going on, such as remembering that you promised a customer a date. Most AI tools sold as an AI executive assistant do the first kind well and the second kind barely, because they can only see one inbox and one calendar.

When you compare tools, ask what each one can read, what it does without asking, and whether it knows anything about your company beyond your own mail. The answers separate an inbox helper from an assistant a company can hand a day to.

The best AI executive assistants, compared

1. Sentra Agent: best AI executive assistant for teams and companies

Sentra Agent is the proactive assistant built on Sentra, the managed organization memory for teams and AI agents. Sentra reads the tools a company connects, such as Slack, email, meetings, calendar, docs, Linear, Jira and HubSpot, and keeps each fact with its source and the newest version on top. Sentra Agent uses that memory to work for one person.

Each morning it texts you on iMessage, WhatsApp or Slack with what you owe, what you are owed and what changed, and you reply with a number to have it draft the follow-up. Before a meeting it sends the one thing to land, then joins, takes notes and catches the new promises. It runs its own browser with the logins you save, so it can book travel, research vendors, compare options and fill in forms.

Reading and drafting happen on their own, but sending, booking, posting and buying wait for your word every time, with no approve-all. The company sets guardrails, such as a spend limit per booking or systems the agent may never touch. It reads only the sources you connect and tick, never other people's DMs, and permissions follow the source tool, so it sees what you could open yourself. When it gets a fact wrong, you reply with the correction and it updates everything that depended on it.

Pricing: Sentra Agent is free to start. The Sentra Team plan for 2 to 20 people is listed at $16 per user per month and is currently free as a launch special; Enterprise is custom and adds API and MCP access for your own agents.

Why it wins for teams: every other assistant here starts from one person's inbox and calendar, while Sentra Agent starts from the company's memory.

2. Lindy

Lindy describes itself as "your AI teammate that plugs into your tools, learns how you work, and takes real work off your plate." It drafts and replies to email, takes meeting notes, answers in Slack threads and works over iMessage, and its site says "nothing irreversible happens without your approval." It is the most configurable tool here, at the cost of setup time. Pricing: a free plan with $50 in credits, and Team at $29.99 per active user per month for 3,000 credits each.

3. Motion

Motion combines an AI calendar assistant that "plans your day for you and schedules meetings automatically" with an AI task planner and project manager that flags deadlines at risk. Pricing: Pro AI $19 and Business AI $29 per seat per month, with a discount for annual billing.

4. Reclaim

Reclaim, now part of Dropbox, is an AI calendar that defends focus time, habits and buffers around your meetings. It does not touch email. Pricing: Lite is free; Starter is $10, Business $15 and Enterprise $22 per seat per month billed yearly. Clockwise, which many people still compare with Reclaim, stopped operating on 27 March 2026.

5. Fyxer

Fyxer works inside Gmail and Outlook. It labels new email so the important messages rise to the top, sums up your calls and drafts the follow-ups for you to review and send. It is the simplest option for someone whose real problem is inbox volume. Pricing: Pro $37 and Team $64 per person per month billed yearly, with a free tier.

6. Superhuman

Superhuman is a fast email client whose AI features include Ask AI, Write with AI in your voice, Auto Drafts, Auto Labels, Auto Reminders and Auto Summarize. Superhuman Mail is included on the Business and Enterprise plans of the wider Superhuman suite, and the plans page shows prices in the visitor's local currency. It suits people who live in email.

7. alfred_

alfred_ calls itself "the AI assistant for client-facing teams." It reads your email and calendar and keeps the requests that need you on one list until you reply. Pricing: from $25 per month billed yearly, and $41.67 per seat per month for teams.

8. Microsoft 365 Copilot

For companies that run on Outlook and Teams, Microsoft 365 Copilot summarizes threads, drafts replies and prepares you for meetings from the Microsoft 365 content you already have access to. It assists inside each app and knows little about work outside Microsoft's tools. Pricing: Copilot Business is $18 per user per month billed yearly under a first-year promotion that runs to 31 December 2026, or $25.20 billed monthly; Microsoft lists the enterprise version at $30 per user per month on annual billing.

9. Gemini in Google Workspace

Gemini in Gmail summarizes threads, turns rough notes into ready-to-send email, suggests replies and finds details buried in your inbox, and Gemini appears across Docs, Meet and Calendar on most business plans. Google says Gemini is included with all Google Workspace subscription plans, so for a Workspace company it is the assistant you already pay for.

10. ChatGPT agent

ChatGPT agent lets ChatGPT use its own virtual computer to research, fill in forms and complete multi-step web tasks. OpenAI says it asks permission before consequential actions such as sending email or making a purchase. It suits one-off jobs rather than following your week. ChatGPT Plus costs $20 per month, and ChatGPT Business is $25 per user per month or $20 billed yearly.

Invite-only consumer agents such as Instinct are also called AI executive assistants. We compare them in our guide to personal AI agents at work.

Personal inbox assistant or an assistant that knows the company?

Most tools above work on one person's mail or calendar, and Copilot and Gemini stay within one vendor's suite. The questions that eat an executive's week usually cross tools, such as whether engineering delivered what was promised on last week's customer call. Answering them needs the company's memory, which is why Sentra Agent is built on it.

If what you actually want is the judgement and follow-through side of the role, read our guide to the AI chief of staff, which covers commitment tracking and meeting briefs for leadership teams. Before rolling any assistant out to a whole team, check how it handles AI agent permissions, since an assistant that sees more than its user could is a security problem rather than a convenience. An approved assistant that people actually like is also the most practical way to cut unsanctioned AI use, because employees stop pasting company data into tools nobody reviewed.

How to choose an AI executive assistant

• You want an assistant that already knows what your company decided and follows company guardrails: Sentra Agent.
• You want to build your own routines: Lindy.
• Your problem is fitting tasks around meetings: Motion, or Reclaim if you mainly need protected focus time.
• Your problem is inbox volume: Fyxer for Gmail or Outlook, Superhuman if you also want a faster client.
• Your company is standardized on Microsoft 365 or Google Workspace: start with Copilot or Gemini, and add Sentra when the answers live outside that suite.
