zero-cost replication of the $200/month pro version of ChatGPT for deep research

Recently, a trending project called "deep-research" on GitHub has replicated ChatGPT's new Deep Research feature. In theory, it can integrate with any large AI model and combine with internet search services, allowing the AI to autonomously search for information on a given topic, delve deeper, and generate a research report. However, it’s currently limited to terminal use, which makes it slightly less accessible. Is there a more user-friendly way to achieve this?

This is a pure front-end webpage that visually displays the entire search process and responds very quickly. You can ask it any questions you want to know, such as summarizing a report on GPT-4.5 and GPT-5 for you.

The usage is quite straightforward; you just need to configure these two services on the webpage:

The API key for the large model service, which currently supports OpenAI-compatible services like OpenRouter, DeepSeek, etc. The API key for the internet search service, currently supporting Tavily, which allows up to 1,000 free searches per month.

The entire process is completed locally in the browser, ensuring data security.
