# Definable AI vs Notion AI

> Notion AI is a $10/month upgrade that bolts AI features onto Notion. Definable is a standalone AI platform — 50+ models, 1000+ integrations, photo and video studios, knowledge bases, developer CLI — and Notion is one of the apps it integrates with.

## 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. Notion AI ships a narrower surface — Definable ships the whole working AI team.

## Overview

Notion AI is positioned as "AI inside your workspace". For Notion-native teams it's a sensible upgrade: summarise pages, draft outlines, autofill databases. The ceiling is exactly that — it's features inside Notion, dependent on your content already living there. There's no integration breadth, no model switching, no creative studio, and no developer tooling.

Definable is the platform tier above. Notion is one of 1000+ apps the Definable Assistant connects to. The Assistant can read pages, write to databases, sync across your other tools, ground answers in private knowledge bases (which can include Notion content alongside PDFs, databases, and Git repos), and route work to specialised personas.

For teams already on Notion: Definable + Notion AI is a perfectly reasonable stack — Notion AI for in-page AI, Definable for cross-app workflows and content beyond Notion. For teams choosing one: Definable's scope is dramatically wider for similar money ($9–$19/month vs Notion AI's $10/month).

## Pricing

- **Definable:** $9/month (Plus) · $19/month (Pro) · standalone, no other subscription required
- **Notion AI:** $10/month per user (Notion AI add-on, on top of Notion)

_Definable connects to Notion via OAuth2; the two stack well rather than compete directly._

## Verdict

Choose Notion AI if your team lives 100% inside Notion and you only need in-page AI. Choose Definable if you want AI that works across Notion plus 999 other apps, with multi-model chat, knowledge bases, studios, and a CLI.
