The best Viktor alternatives

Every person gets their own agents, and they work together: a coordinator splits big jobs between specialists, what one agent learns the whole workspace knows, and teammates' agents check with each other. They're in Slack too, and in iMessage and WhatsApp, including the group chats with your suppliers or crew, and they join your Meet, Zoom, Teams and Webex calls.

What it is

AI agents you text on iMessage and WhatsApp, mention in Slack or email, and add to your group chats, where they keep every message and file and follow up on what people promised.

Where it works

iMessage and WhatsApp (one-to-one and group chats), Slack, email and a web app

What it costs

300 free credits to start with a card at sign-up, then $25 for 200 credits when you run low, or plans from $99 a month. Credits are shared across the workspace and roll over.

Worth knowing

Built for work rather than personal shopping and errands, and phone calls are switched off for now.

An always-on agent for each person in ChatGPT, Slack and Teams, with its own cloud computer, if your company is on ChatGPT Business Premium or Pro.

What it is

OpenAI's always-on agents inside ChatGPT, each with a cloud computer of its own, launched in September 2026.

Where it works

ChatGPT on desktop, web and mobile, Slack and Microsoft Teams; texting (iMessage or RCS, one-to-one) in a US beta for some Pro users since 28 October

What it costs

Included with ChatGPT Pro (from $100 a month) and Business Premium seats; Enterprise in beta

Worth knowing

One primary dot per person today, texting only in a one-to-one US beta for some Pro users (no group messages), and it needs a $100-a-month plan to start.

A Slack teammate for each person, also in iMessage and SMS, with a meeting notetaker; Team from $49.99 a month per active user.

What it is

An AI assistant you text, mention in Slack or email, with a meeting notetaker and a Chrome extension.

What it costs

Free to try with $50 of credits for 7 days; Team from $49.99 a month for every active user, credits pooled; Enterprise priced on request

Worth knowing

No WhatsApp that we could find, every active user is billed, and its docs say approvals apply in shared Slack threads, not in DMs, iMessage or SMS.

If you'd rather run the team's work in one suite: tasks, projects, calendar and docs, with AI employees inside it and a notetaker, from $19 a seat.

What it is

A work suite (tasks, projects, calendar, docs and a notetaker) that auto-schedules your day, with AI employees that work inside it.

Where it works

Motion's web, desktop and mobile apps; forwarded emails, and Slack or Teams messages, become tasks

What it costs

Pro AI $19 and Business AI $29 a seat a month, with monthly credits; free trial

Worth knowing

Your work moves into Motion, it isn't something you text that we could find, and every seat is paid after the trial.

Worth knowing

Not in iMessage or WhatsApp that we could find, it posts to Slack rather than talking there, and it works from your notetaker's output instead of joining calls.
