Why it comes up: An AI coworker that joins your existing Slack instead of replacing your chat, with published pricing from $50/mo.
Stands out: OpenTag is priced per job, not per seat, so everyone in an invited channel shares one coworker. It notices repeated asks and offers to automate them, instead of waiting for someone to build a workflow.
Watch out: Slack is the only generally available platform; Microsoft Teams is invite-only. SOC 2 Type II is in progress, not complete, and the vendor lists job costs as ranges from 25 to 1,250 credits.
Best for
- Startups that run operations out of Slack
- Teams tired of pulling the same weekly numbers by hand
- Companies that want one shared agent instead of per-seat AI licences

Why it comes up: A conversational hiring assistant built only for recruiting, strongest in high-volume hourly hiring.
Stands out: Purpose-built packages for Workday and SAP SuccessFactors estates.
Watch out: No published price, and it is far more product than a small professional-hiring team needs.
Best for
- High-volume hourly employers
- Talent teams already on Workday or SuccessFactors
- Teams buried in SMS and scheduling back-and-forth

€20/mo Free tier Free trial MCP API
Why it comes up: Self-hosted AI agent workflows if you want to build and own each automation yourself.
Stands out: Billing counts full workflow executions, not individual steps, and the Community edition is free to self-host.
Watch out: Cloud prices are published in euros only. The Cloud trial is capped at 1,000 executions, and unused AI Assistant credits do not roll over.
Best for
- Technical teams that want to self-host for free
- Builders who prefer per-execution billing
- Teams that want to drive workflows from Claude via MCP

Why it comes up: Visual scenarios with AI agents when the job is a defined process rather than asks in a chat channel.
Stands out: Make's drag and drop canvas shows every branch, router and iterator of a scenario, with real time run monitoring, which suits complex multi branch automations better than linear step lists. Greenhouse and Workday are among its enterprise apps.
Watch out: Every module action uses a credit, including reads, searches and iterations, so polling scenarios and loops burn credits fast. The Free plan allows only two active scenarios and a 15 minute minimum interval, and enterprise apps are reserved for the top tier.
Best for
- Ops builders who think in flowcharts
- Scenarios with many branches, loops and error handling
- Teams that want AI agents and MCP inside their automations
