The best AI executive assistants

Role it fills: Runs the business: site, sales, support and marketing

For a small team that wants one AI teammate to take work off everyone's plate, Crevio covers the most ground of anything we rank. It doesn't stop at drafting: it acts in the business, on a schedule or when something happens, like a new order or an inbound email, and it asks before anything consequential. The tradeoffs are credit-based billing that rises with use, a 2.5% fee on sales you take through it, no Microsoft Teams app, and a younger company with fewer public reviews than the big names.

Role it fills: Generalist teammate for reports, ops, outreach and internal apps

Viktor is the best pure AI coworker for a team that already runs on Slack or Teams. It has excellent reviews, no per-seat fees, and real controls: each tool can run automatically or ask first, with approve and reject cards in the channel. It's built for teams with an existing stack, not for running a website or taking customer payments, and long background tasks can burn credits quickly.

Role it fills: Generalist teammate for research, writing, analysis and code

Claude is the strongest thinker on this list for the price of a seat, and Claude Tag makes it a genuine Slack teammate that remembers channel context and can pursue work over days. It works through connectors rather than owning parts of the business, scheduled tasks run on a clock rather than on events, and Tag is still in beta.

Role it fills: Generalist assistant for research, writing and analysis

ChatGPT Business is the familiar default: everyone already knows how to use it, and seats are cheap. As a coworker it's mostly something people go to rather than something that works among them: it reads from Slack and email through connectors but doesn't sit in your channels or act in the business on its own.

Role it fills: Assistant across Outlook, Teams, Word, Excel and PowerPoint

If your company runs on Microsoft 365, Copilot is the natural pick: it already knows your files, mail and meetings, it works inside Teams, and it comes with enterprise-grade security. It's an assistant more than a teammate. It's best at drafting and summarizing, its more autonomous features cost extra by usage, and it does nothing outside the Microsoft world.

Role it fills: Executive assistant for inbox, calendar, meetings and calls

Lindy is the best AI executive assistant here: inbox, calendar, meetings and the phone in one coworker, reachable from almost anywhere, with top G2 ratings and strong compliance. It's an assistant to a person more than a teammate to a team, and credits drain fast when it has to redo work.

Role it fills: Seven role-based AI employees, from inbox to receptionist

Marblism is the best value for role-based help: seven AI employees, including a phone receptionist, for $24 a month on annual billing, with unlimited businesses and team members. Each role is shallower than a dedicated tool, it doesn't live in your team's chat, and a 50-hour monthly cap limits heavy use.

Role it fills: Assistant across Gmail, Docs, Sheets, Meet and Chat

For a Google Workspace team, Gemini is the best value here because it's already in the plan you pay for. Like Copilot, it's an assistant inside your documents more than a teammate you delegate whole jobs to, and it isn't built to act outside Google's apps.

Role it fills: Meeting notes and search across meetings, email and chat

Read AI is a strong, cheap meeting teammate with a real free plan. It remembers what was said, but it doesn't go and do the follow-up work.

Role it fills: AI planner for tasks, projects and calendars

Motion is a good AI planner that keeps a team's calendar and task list honest. It's not really a coworker you hand jobs to, and the named AI employees it used to sell are no longer on its pricing page.
