Dia - AI Tools Nav

What it is for

Dia is The Browser Company’s AI browser: a Chromium window that can summarize the open tabs (cover: Chicago offsite workshops) and, on paid plans, chat with connected tools. Use it when the job is a browser with tab-aware answers, not when you only need Chrome plus an extension.

Better Browser is Free and has no AI. AI sits on Better Answers and Better Days. New users get a 14-day Better Days trial (no card); then AI pauses unless you subscribe.

What makes it unique: the cover is Dia’s official product still — multi-tab chrome, a workshop-idea chip, and a sourced summary of open docs — not the yellow DIA wordmark poster.

Key features

Ask on the open tabs — summarize what several docs/tabs are about (cover; Plans).
Chat with connected tools — Gmail, Calendar, Notion-class connectors on paid plans (Plans).
Models that won’t store your data — listed on the Better Answers card (Plans).
Morning Brief — daily briefing on Better Days (Plans).
Reports / decks / recaps — generate a sendable artifact from the same context (Better Days card).
Free browser chrome — profiles, tab groups, split-view, PIP, ad/tracker block, sync — without AI on Better Browser (Plans).

Who it's for

Best fit: Arc / The Browser Company users who want tab-aware chat and will pay for AI.

Poor fit: people who want a $0 AI browser (Perplexity Comet) or who refuse a second Chromium.

Pricing

Verified 2026-10-22 (Asia/Shanghai) from diabrowser.com/plans. The same official page prints two Better Answers dollars: the plan card shows $10/month; the FAQ on that page says Better Answers ($20/month). We will not pick a winner. Confirm the number on the checkout you see.

Better Browser — $0. No AI. Profiles, tab groups, split-view, blocker, sync.
Better Answers — $10/month on the card / $20/month in the FAQ. Ask on any page; chat with tool context; no-store models.
Better Days — $100/month. 6× usage, Morning Brief, reports/decks/recaps, meeting prep/follow-up.
Usage top-ups — extra $20 blocks (auto-reload or one-time). Allowance does not roll.
Trial — 14 days of Better Days, no card. Then AI pauses.

Enterprise: teams@diabrowser.com (unpriced).

Limitations / costs

Free has no AI. After the trial, Dia is just a browser unless you pay.
Official $10 vs $20 conflict on Better Answers. Cite both; pay the checkout.
Usage is “Tasks,” not messages — heavy tool calls cost more than a short ask.
Paid AI rolled to new Mac users first; Windows was called out as later. Confirm your OS.

Alternatives

Perplexity Comet — free AI browser + Comet Plus $5.
ChatGPT — hosted assistant if you do not want a new browser (Plus $20).
Kagi — paid search/browser tools if the job is results quality, not tab chat.
