Puma: a private local AI browser (and ChatGPT alternative)

If you use ChatGPT, Claude, or Gemini on your phone, every prompt usually travels to a cloud API. That is fine when you want maximum model power. It is less fine when you are summarizing a medical page, drafting a personal note, or browsing something you would rather not send to a third-party server.

What “local AI browser” means

Puma is a mobile browser with on-device models baked in. You can chat with open models such as Gemma, Qwen, and Ministral without the conversation leaving your device. Page help and summarization can stay local too — or you can opt into cloud APIs (OpenAI, Anthropic, Gemini) when you want more horsepower.

Why people switch from cloud chat apps

• Privacy by default — local chats do not need an account sync pipeline.
• Works with the open web — AI sits next to browsing, not in a separate silo.
• Offline-friendly — once models are on device, basic chat and page help can work without a network.
• No annoying ads — Puma does not monetize by tracking your browsing.

Private ChatGPT alternative — without giving up the web

ChatGPT is excellent software. Puma is not trying to clone every cloud feature. It is a browser first: tabs, links, ENS/IPFS sites, wallets — with local AI as a first-class tool beside the page you are reading.

That combination matters for search intent like “private ChatGPT alternative” or “local AI browser.” You are not only chatting; you are browsing with an assistant that can stay on the phone.
