Custom AI triggers: create rules that work like you do

Define once, automate forever. Set precise if-this-then-that rules for keywords, tags, creators, or dates; Workast’s AI handles assignment, subtasks, Slack notifications, and reminders with parent/subtask awareness so nothing slips and every task moves to done faster.

Every team has little rules they follow over and over.

“If it’s urgent, assign it right away”

“If a task says ‘invoice,’ tag it #finance”

“If a meeting wraps, schedule the follow-up”

Instead of relying on people to remember these steps, you can let your AI agent handle them automatically with Custom AI triggers. Think of them like “if-this-then-that” rules—AI is always watching for the signals you set (keywords, dates, tags) and reacts instantly.

Watch for signals

AI can be trained to notice exactly what matters to your team:

Keywords: invoice, contract, bug, campaign
Tags: #urgent, #client
Dates: due today, due in 30 days

Fire off the response

When a trigger is hit, Workast takes action:

Assign work → If the task mentions “website”, assign it to @Dev.
Add tags → If a task contains the word “invoice”, tag #finance.
Follow-ups → If a subtask that mentions “meeting” is done, create another subtask “Send recap” with a due date for the next day.
Checklists → If the task says “onboarding”, create the subtasks: Welcome email / Setup / Kickoff.

Quick examples

Finance: If task contains the word “invoice”, assign it to @Jonas, tag #finance, and set due in 3 days.
Client follow-up: If subtask “meeting” is completed, add a subtask “Send recap email” due the next day.
Marketing: If a task is tagged #social, assign it to @Riley and generate the subtasks Draft copy / Design assets / Schedule post.

Advanced prompts in action

Go beyond “watch for invoices”. Define multi-condition rules with AND/OR logic, parent/subtask awareness, and creator-based behavior so your AI agent reacts exactly to your workflow, not generic triggers.

No missed details. Smarter rules. Consistent execution.

With Custom AI triggers, you don’t just automate the basics—you encode your team’s unique rules into Workast. It’s an AI Agent that catches the specifics, applies the logic, and keeps your workflows running without interruption.
