按需選擇
哪款免費 AI 瀏覽器適合你？
I want to automate tasks and let AI do the work
Tabbit
Only Tabbit gives you full agent mode for free — it can browse, click, fill forms, extract data, and run multi-step workflows autonomously.
I care most about privacy
Brave Leo
Brave has the strongest privacy track record. Its AI runs locally or through private relays. But you'll need Premium for advanced models.
I want AI in a browser I already know
Edge Copilot or Opera Aria
Both feel like traditional browsers with AI added on. Good for quick questions but lack the automation depth of AI-native browsers.
I use ChatGPT every day
ChatGPT Atlas
Atlas integrates deeply with your ChatGPT account. But the free tier is limited — agent mode requires a $20/mo ChatGPT Plus subscription.
I want the most AI models for free
Tabbit
Tabbit gives you free access to GPT-5.2, Claude Sonnet 4.6, Gemini 3.1 Pro, DeepSeek, and 10+ more models. No other free browser comes close.
I'm on a budget and need everything free
Tabbit
Tabbit is the only AI browser with zero paywalls, no daily limits, and no feature restrictions. Everything is free, forever.
注意陷阱
「免費」AI 瀏覽器中的隱藏成本
很多 AI 瀏覽器聲稱免費，但把最好的功能藏在付費牆後面。以下是最常見的陷阱。
Perplexity Comet
Only 5 AI queries per day on the free tier. Agent mode and advanced models require $20/mo Pro plan.
ChatGPT Atlas
Agent browsing mode is locked behind ChatGPT Plus ($20/mo). Free users get basic GPT-4o mini only.
Brave Leo
Free tier uses Llama 3 only. Premium models like Claude require a $14.99/mo subscription.
Edge Copilot
Copilot Pro is $20/mo for full GPT-5 access and advanced features. Free version is limited to GPT-4o.
Dia Browser
Currently in limited beta. Future pricing structure is unknown — "free now" doesn't mean "free forever."
