The best AI customer support coworkers

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: 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: Build multi-agent teams for sales, support and ops

Relevance AI is a powerful builder for sales and ops teams at established companies. For a small team it's a lot of setup, billing has two moving parts, and the public pricing page now says only "talk to sales."

Role it fills: AI sales reps for outbound email and inbound calls

11x is the deepest AI sales hire here, covering outbound research and email plus inbound voice qualification. It's priced like a real hire: third-party reports put the entry plan at about $36,000 to $45,000 a year on an annual contract, which is out of reach for most small teams.

Role it fills: Twelve AI helpers for social, email and content

Sintra is an easy, inexpensive content team for social posts and email. It doesn't live in your team's chat or act much beyond content, its 250 monthly credits run out quickly, and Trustpilot withholds its rating over review incentives.
