Ranked by support score

1. Ace by Automat

AI employee for teams

An AI teammate with its own Mac, inbox and phone number that you reach on Slack, Teams, email, text, WhatsApp or a phone call, and that does the work inside the tools you already use.

Best for: controlling complex multi-step workflows

Documented strengths

AI & human control: AI model steps, Autonomous agents, Browser or computer use, MCP support and Human approval steps
Reliability & operations: Retries and error paths, Run history and logs, Testing and debugging, Workflow versioning and Secret management
Build & trigger: Visual workflow builder, Schedule trigger, Webhook or API trigger and Email, form, or manual trigger

The catch

The gap is workflow builders and triggers, with nothing documented for App-event trigger.

Pricing

Workforce$1,800/moyrEnterpriseCustom pricing

Workforce: $1,800 per month billed annually ($21,600 a year) or $2,000 per month month-to-month after a 7-day free trial, no per-seat pricing. Enterprise (managed automations): custom, "scoped to the outcomes you need". · no free tier · runautomat.com

How it differs from Notis: Hired, not integrated: Ace gets a dedicated Mac, its own email, phone number and logins in your existing apps, is onboarded and managed by Automat's team, and sits on the same agentic workflow platform that runs Automat's managed enterprise automations.

Best for: building and triggering workflows

Documented strengths

Build & trigger: Visual workflow builder, Build workflows with natural language, Schedule trigger, App-event trigger, Webhook or API trigger and Email, form, or manual trigger
AI & human control: AI model steps, Autonomous agents, Knowledge bases or RAG, Browser or computer use and MCP support
