# Definable AI vs Zapier

> Zapier is a rule-based workflow tool. Definable is an AI-native automation platform. Where Zapier needs you to design every if/then branch, Definable lets you describe the goal in English and lets the AI orchestrate the steps — across 1000+ of the same integrations.

## Why Definable wins

Definable is a multi-agent workflow platform. The Builder agent plans every workflow from a plain-English prompt, the Executor runs each step across 1,000+ apps and 50+ models, and the Verifier self-heals failed steps automatically. Zapier ships a narrower surface — Definable ships the whole working AI team.

## Overview

Zapier built the modern app-automation category. It's deep, mature, and supports thousands of apps. But it's also fundamentally rule-based: you draw zaps step-by-step, code conditional branches by hand, and pay per-task. AI in Zapier is a step you call out to, not the orchestrator.

Definable inverts that. The Assistant is an AI agent that calls integrations as tools — describe "every Monday morning, pull last week's deals from HubSpot, summarise them, and post the digest to #revenue with a Loom-friendly version" and the AI figures out the steps. Memory persists across runs. Knowledge bases ground every decision. And because the AI has 50+ models behind it, you pick the model that fits each task.

Pricing matters too. Zapier's middle tier is $30+/month and meters tasks. Definable Plus is $9/month with 25,000 credits — a "credit" covers a model call, an integration call, and surrounding orchestration. Pro at $19/month gives 100,000+ credits and unlimited knowledge bases.
