Pricing

Plans as listed on each vendor's site when we last checked. Confirm before you buy.

Attribute	Dia	Manus
Plans	Better Browser Free People who want a tidy browser without AI.	Free Free Quick questions and seeing what it can do.
	Better AnswersOur pick $10 to $20/mo (Dia's page shows both) Anyone who wants the AI chat day to day.	ProOur pick From $20/mo, less with yearly billing Anyone who wants to hand off real research and build jobs.
	Better Days $100/mo Heavy users who want the full workday assistant.	Pro (higher tier) From $40/mo, less with yearly billing Heavier users and anyone publishing websites with it.
	Dia for Work See website Companies rolling it out to staff.	Team From $20/seat/mo Teams that want shared credits and admin controls.
		Enterprise Custom Large organisations.
Which plan to pick	Use the 14-day trial properly, then decide if the chat alone is worth $20 a month to you. Better Days at $100 only makes sense if the Morning Brief and meeting prep save you real time every day. Existing users keep their free AI for now, with 30 days' notice before that changes, and Windows users aren't on the paid plans yet.	Try the Free plan for a week to get a feel for how many credits a real task uses, then move to the $20 Pro tier. Only go higher if you run out most months or you want it to publish websites for you.

Pros and cons

Attribute	Dia	Manus
Pros	Beautiful, calm design that is easy to pick up Asking across several tabs at once works well Connects to the work apps most teams already use Skills save time on repeated prompts Imports from Arc, Chrome and others in a few clicks	You describe the result, not the steps Strong at research, reports and first-draft decks Scheduled tasks turn it into a hands-off research assistant Apps for phone, desktop and browser
Cons	New Mac users lose the AI after the trial unless they pay $20 or $100 a month Arc users miss Spaces, nested folders and Little Arc No phone app, and Windows only arrived in October 2026 Reports of freezes, crashes and heavy battery use on Mac Memory was removed in September 2026, and new sign-ups now need an Atlassian account	Credits are hard to predict and one big task can drain the monthly allowance Output needs checking, and it can waste credits on dead ends Not suited to automations that must run the same way every time Few direct app connections compared with the automation tools Pricing page does not load without JavaScript, so plan details are hard to confirm
