What It Is

PluriHub is a free Chrome extension aimed at users who work with multiple AI tools, positioned as “One Sidebar for Every AI Tool.” According to the product page, it can save and organize conversations from ChatGPT, Claude, Gemini, and Perplexity in a single sidebar, helping users reduce the friction of searching through history across different AI platforms.

Core Features and Use Cases

Based on the publicly available information, PluriHub is not a new AI model or generative AI app. Instead, it is a browser tool focused on managing AI conversation history. Its main value lies in providing a unified entry point: when users work with several AI chat products at the same time, they can save and organize related sessions centrally in the Chrome sidebar. Typical use cases include organizing research materials, reviewing workflow history, and archiving records after comparing outputs across different models.

Pricing, Integrations, and Privacy

The page explicitly mentions “free Chrome extension” and “Install free,” so it can currently be considered free to install. However, it does not disclose whether there will be a premium version, usage limits, or future paid plans. In terms of integrations, it supports ChatGPT, Claude, Gemini, and Perplexity, and highlights “No API keys,” which lowers the barrier to entry because users do not need to apply for or configure model APIs separately. On privacy, the page states “No data extraction,” which is a positive signal. However, it still lacks details on where data is stored, what browser permissions are required, how syncing works, whether encryption is used, and the specifics of its privacy policy. Enterprise users or anyone handling sensitive data should evaluate it carefully.

Pros, Cons, and Who It’s For

Its advantages are that it is lightweight, free, does not require an API key, and covers major AI chat platforms. It is suitable for individual users, researchers, content creators, and product/operations teams who frequently use multiple AI assistants. The main limitation is the lack of public information: it is unclear whether it supports search, tags, export, cloud sync, or a Chinese interface, and its stability and long-term maintenance are also hard to assess.

Access from China and Alternatives

Access from mainland China is unknown. Even if the extension itself can be installed, the services it depends on—ChatGPT, Claude, Gemini, and Perplexity—may face network access restrictions in mainland China, so the actual user experience may be affected. Alternatives include each platform’s built-in history, browser bookmarks/history, manual archiving in Notion or Obsidian, and other browser sidebar or chat-history management extensions.
