Is Comet Browser free?

A free tier exists, with paid expansion expected for heavier AI usage. Treat the free limit as an operational constraint and model your weekly query volume before committing a team.

Is Comet Browser safe?

Perplexity’s data policies are generally transparent, but any browser that lets an AI click on your behalf raises legitimate questions. Read the latest privacy and agent disclosures, and use human-in-the-loop approvals for sensitive accounts.

Does Comet Browser work on desktop?

Comet’s Android app launched first and is the most mature. Desktop clients for macOS and Windows have been staged and more limited—check the official site for your platform.

Is Comet better than Chrome?

For quick AI-assisted search and summaries, Comet can feel faster and more modern. For full extension support, enterprise policy tools, password managers, and mature bookmark migration, Chrome still leads.

What are Comet’s biggest weaknesses?

Early reviews and store feedback point to missing password management, incomplete bookmark migration, a mobile-first rollout, and an AI-agent model that still requires careful oversight.

Is Tabbit free on macOS and Windows?

Yes—Tabbit is free during public beta on macOS and Windows. It offers multi-model choice, Agent Mode with checkpoints, and knowledge-base bookmarks.

Can I use Comet and Tabbit together?

Yes. A common split is Comet for quick mobile search and Tabbit for desktop research and delivery workflows that need execution and control.

Comet Browser レビュー

Comet は Perplexity が挑む AI ネイティブブラウザです：ブラウジング中に買い物、検索、要約を行う対話型エージェント。2025–2026年の公開情報とストアフィードバックを総合すると、コンセプトは魅力的ですが、デスクトップ成熟度やパスワード管理、ブックマーク移行は追いつきつつあります。

Comet Browser レビュー基準

デモの華やかさと日常の信頼性を分けて考えましょう。10 分ツアーではなく、実際の作業スプリントで使ってください。

シグナル	確認ポイント	2026年の Comet 読み
Agent usefulness	Can the browser actually complete multi-step tasks (shop, search, compare) without brittle failures?	Strong for quick search-to-memo and shopping-style flows; treat purchase/account actions as human-in-the-loop.
Platform & form factor	Is the desktop experience on par with mobile, and does it cover both macOS and Windows?	Android app is live and polished; desktop rollout has been more limited and staggered—verify official download pages.
Security & privacy posture	Is page context handled transparently, and are sensitive actions clearly gated?	Perplexity’s data handling is generally trusted, but an AI that can click on your behalf raises policy questions—read disclosures.
Migration friction	Can you bring passwords, bookmarks, and extensions from Chrome/Edge/Safari?	Store reviews and early reports flag missing password manager and incomplete bookmark import as real blockers.
Pricing realism	Does the free tier cover daily AI usage, or will you hit a paywall mid-week?	Freemium with paid expansion is expected; model your query volume before standardizing a workflow.

バランス表

Comet Browser の長所・短所と結論

レビューで一致しやすい長所

●AI agent woven into browsing, not just a sidebar—good at search, summaries, and shopping-style tasks.
●Perplexity search backbone gives fast, citation-friendly answers.
●Lightweight and snappy for focused work, often faster than Chrome in early tests.
●Clean, minimal interface that keeps the page front and center.
●Strong mobile / Android execution if your workflow is phone-first.

想定しておくトレードオフ

●No built-in password manager and limited bookmark migration, according to Play Store and early reviews.
●Desktop availability (macOS / Windows) has been staged and narrower than mobile.
●AI actions that touch accounts or carts need careful approval policies.
●Single-vendor AI stack: less flexibility if you want to compare GPT, Claude, Gemini side by side.
●As a newer browser, extension and enterprise-policy support trails Chrome/Edge.

Bottom line: Comet Browser is worth a look if you want an AI agent that shops and searches for you, especially on mobile. If your main computer is a Mac or PC, or if you need password management, multi-model choice, and guarded cross-site automations, test Tabbit on macOS & Windows before you settle.
