Fishtail: Official Launch of the Built-in AI Assistant for Browsers

In an era of information overload, we often encounter unfamiliar terms, complex concepts, or hard-to-identify images while browsing the web. Fishtail integrates AI conversational capabilities into your browser to help you understand, query, and analyze webpage content in real time, making your reading and learning more efficient.

What is Fishtail?

Fishtail is a smart AI browser extension that enables contextual interaction with both text and images on webpages. Whether you're reading articles, viewing pictures, or researching information, simply highlight the content you want to explore and click the trigger button to ask the AI directly.

A chat sidebar will open on the current page, allowing AI responses without the need to navigate away or interrupt your reading experience.

Key Features

1. On-Page Interaction – Seamless Operation
Highlight any text or image to query the AI. No copying, pasting, or opening new tabs required. Fishtail provides instant answers on the same page.

2. Multi-Model Support – Flexible Switching
Fishtail comes with a rich library of AI models, covering mainstream options and various versions, such as GPT-4o, o4-mini, Claude, DeepSeek, and more. You can:

• View detailed introductions for each model
• Check pricing for input and output tokens
• Switch models based on task needs

3. Web Search Capability – Access Real-Time Information

Some models (e.g., Gemini) support live web search, offering access to up-to-date content. This feature is particularly useful for querying time-sensitive information like news, policies, or prices.

Application Scenarios

• Image Recognition and Visual Q&A

Curious about a landscape, character, or movie scene on a webpage? Click the image and ask the AI for its context, origin, or meaning.
