What sets ChatGPT and Notion AI apart
ChatGPT counts among the AI agents and Notion AI among the AI writing tools, so they meet only where their results overlap. Both ChatGPT and Notion AI list documents. Only ChatGPT lists research with sources, presentations, spreadsheets, charts and dashboards, images and code. Only Notion AI lists automations. Both can be tried for free: ChatGPT offers a Free plan with limited deep research, uploads and image generation, Notion AI a Free plan. Notion AI prices some plans per seat, so its cost grows with the team, while every plan ChatGPT lists has one price.
Pricing: ChatGPT vs Notion AI
ChatGPT's paid plans: Go USD 8 a month; Plus USD 20 a month and Pro from USD 100 a month.
Notion AI's paid plans: Plus from USD 10 per seat a month and Business from USD 20 per seat a month (Custom Agents). Notion AI works on what is already in your Notion workspace, and Custom Agents need the Business plan and Notion credits at USD 10 per 1,000.
Credits are counted differently by each product, so run one real task in both before you decide.
Where ChatGPT is stronger
Plus adds deep research, projects, scheduled tasks, custom GPTs and more Codex usage. The pricing page lists extensions for Excel, Word, PowerPoint and Google Sheets.
Where Notion AI is stronger
Business includes Custom Agents that handle repetitive tasks on their own. Documents, wikis and databases live in the same workspace as the AI. Plus costs USD 10 per member a month.
A third option: Siteglade
Neither ChatGPT nor Notion AI lists websites, web apps, mobile apps and desktop apps on its pricing page. Siteglade does. It plans the pages, designs them, writes the copy and builds a real website you can edit by clicking, then publishes it to a free siteglade.page address or, from Pro, your own domain.
Where Notion AI works inside your Notion pages, Siteglade produces standalone files, sites, apps and videos. Every task runs in a sandbox on servers in the EU, and code can be exported on every plan.
