What are the best alternatives to Lindy for small businesses?

Start with where your team already works. If that is Slack or Microsoft Teams, look at HiToby and Viktor. Both work in your channels and both charge per workspace, not per person. Lindy works in Slack, bills every active user, and its docs list Microsoft Teams as coming soon. If you would rather use a separate app with ready-made AI characters, look at Sintra or Marblism.

Viktor vs other AI employees in Slack: which one should you pick?

Viktor and HiToby are the closest match. Each is one shared AI employee you mention in a Slack or Teams channel, and each bills the workspace rather than the seat. The gap is price. HiToby starts at $25 a month after 2,000 free credits. Viktor's smallest Team plan is $50 a month for 20,000 credits, and its default Team plan is $100 for 40,000.

Lindy also works in Slack channels, but anyone who uses it, including by mentioning it in Slack, takes a paid seat. Sintra and Marblism do not sit in your channels at all.

Sintra vs Marblism vs other AI employee platforms for a small agency

Sintra and Marblism sell a team of named AI characters that work in their own app. Sintra has 12, from a copywriter to a social media manager. Marblism has seven, including a receptionist that answers calls. That suits an owner who wants marketing and inbox help in one place. If your client work already runs through Slack or Teams threads, HubSpot and Notion, one coworker in those threads may fit better.

FAQ

Is there a cheaper alternative to Lindy for a whole team?

Lindy bills each active user, from $29.99 a month. HiToby bills the workspace instead: Starter is $25 a month for 20,000 credits that everyone shares, after the first 2,000 free credits. Credits are measured differently in each product, so put the headline prices side by side and then run the same job in both.

Is there a Lindy alternative that works in Microsoft Teams?

Yes. HiToby works the same way in Slack and Microsoft Teams: you mention it in a channel and it does the job in the thread. Viktor also works in both. On 9 November 2026 Lindy's setup docs listed Microsoft Teams as coming soon.
