ショートリスト

AI機能が最も優れたブラウザランキング

Tabbit Browser

Best Overall

The only AI-native browser that combines full agent automation, frontier models, and workspace productivity for free.

Score:9.6 / 10

Best for:Power users, researchers, builders

Perplexity Comet

Best for AI Search

Excellent AI search with citations, but agent mode and unlimited use sit behind a $20/mo Pro plan.

Score:8.2 / 10

Best for:Perplexity subscribers

ChatGPT Atlas

Best for ChatGPT Users

Great if you already pay for ChatGPT Plus. Otherwise agent browsing is locked and you are tied to OpenAI models.

Score:7.9 / 10

Best for:ChatGPT Plus subscribers

Microsoft Edge Copilot

Safest Default

A solid mainstream choice for quick AI help, but Copilot's agent capabilities are shallow compared to AI-native browsers.

Score:7.3 / 10

Best for:Corporate users

Dia Browser

Best Design

Beautiful chat-first interface, but still beta and macOS-only, with weaker agent depth than Tabbit.

Score:7.1 / 10

Best for:Mac users who value UI

詳細

TabbitのAI機能が最高である理由

Agent Mode

Give Tabbit a multi-step task in plain English. It opens tabs, reads pages, clicks buttons, fills forms, and delivers results while you keep working.

Omnibox with @ Context

Type @ to reference any open tab, tab group, screenshot, bookmark, or local file. The AI sees what you see — no more copy-paste.

Skills Marketplace

Save prompts as reusable Skills, or discover community scripts that clean pages, extract assets, and restyle websites with one command.

Vertical Tabs & Workspaces

Smart grouping, full titles, and permanent bookmark archiving turn chaos into a focused workspace built for deep work.
