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
Tabbit includes web and document tasks on Free, everyday Agent use on Standard, and fuller capability on Pro.
I care most about privacy
Brave Leo
Brave says Leo does not retain chats or use them for model training, and it supports local or remote bring-your-own 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 want the most AI models for free
Tabbit
Tabbit lists multiple model families on Free and Standard. Exact versions and regional availability can change; top models are reserved for Pro.
I'm on a budget and need predictable free access
Tabbit
Start with the weekly Trial allowance, or set Tabbit as your default browser for the free Standard allowance at 10× Trial usage.
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。
Tabbit
Trial and Standard use weekly allowances. Standard is free when Tabbit is your default browser; top models and heavier Agent use sit in Pro.
Brave Leo
Free access varies with traffic and usage. Leo Premium offers higher limits, more models and faster responses.
Opera Aria
Opera presents Aria as a free built-in assistant. Its official page does not promise every future model, feature or regional rollout.
