The reasons to look beyond Demi are narrow but real. The download is offered for Mac only, and usage is metered in credits, with 5,000 per month on the $25 Individual plan. Team pricing is a custom quote, and you must create an account and connect your tools before it does anything useful.
ChatGPT is a general assistant for writing, research and analysis with a free tier; its Plus (consumer) plan is $20 per user per month. Claude covers similar ground with free and paid plans, and Pro is $20 per user per month. Notion AI suits you if your notes and meeting records already live in Notion: Plus is $12 per member per month and has a free tier. None of the three is a Mac agent built around your inbox, so expect to do more of the wiring yourself.

Why people look beyond Demi
Download offered for Mac only Windows and Linux users cannot use it
Individual includes 5,000 credits per month Heavy users must top up
Team pricing is a custom quote Cannot budget without sales contact
Taken from the documented limitations in our Demi profile.
Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription.
Full AI needs Business or Enterprise, and even there a rolling six-hour and monthly usage allowance applies; premium models, Custom Agents and Workers consume separately purchased Notion credits.
