What is ChatHub?
ChatHub is the world’s most popular browser-based AI aggregator extension, trusted by over 15 million users globally. It does not build its own large language models (LLMs) or generate AI content directly. Instead, it integrates 100+ leading AI services into a single browser sidebar, eliminating the need to switch between dozens of tabs and websites to access different AI tools.
Unlike cloud-based aggregators such as Poe or Felo, ChatHub runs entirely on your local device and connects directly to each AI provider’s servers. No conversation data passes through ChatHub’s servers at any point, solving the core privacy risk that plagues most third-party AI platforms.
5 Core Features (No Marketing Fluff, All Practical Value)
Switch Between 100+ LLMs in One ClickFull support for all major models including GPT series, Claude series, DeepSeek V4, Gemini 3.1, Doubao 4.0, Kimi 2.5, MiMo V2.5, and more. New models are added within 72 hours of their official release.
Side-by-Side Multi-Model ComparisonOpen up to 4 models simultaneously. Ask one question and get 4 distinct answers at once, allowing you to instantly compare accuracy, creativity, and reasoning without copy-pasting between tabs.
Persistent Browser SidebarAccess ChatHub from any webpage with a single click or keyboard shortcut. Extract content from any web page or PDF with one tap and ask AI questions about it directly, without leaving your current tab.
Global Prompt LibraryBuilt-in library of 1,000+ professionally crafted prompt templates. Create, categorize, and sync your own custom prompts across devices, eliminating repetitive typing.

OpenRouter
OpenRouter is a unified LLM API layer for developers who want one endpoint for many models and providers, with model browsing, provider routing, fallback logic, zero-data-retention controls, and bring-your-own-key options. Its strongest fit is teams comparing models, controlling costs, or keeping provider flexibility without rewriting every integration; the tradeoff is that it is infrastructure, not a finished AI workspace or no-code app.
Poe
Poe is a multi-model AI platform for users who want one place to access many leading text, image, video, and audio models instead of managing separate sites for each one. It is especially useful for comparison-heavy workflows because the platform supports different bots, user-created bots, and multi-bot conversations inside the same product.
Felo
Felo is worth recommending when it is judged as a web research and answer-synthesis tool instead of as another generic AI chat tab. The official materials checked on April 22, 2026 still position Felo through its main site, version update page, explanation of how Felo Search works, main feature guidance, image and video search support, search modes, file upload workflow, Felo Pro value, subscription and billing guidance, and account management guidance. That combination matters because many readers do not only want a chatbot that talks confidently. They want a faster way to search several sources, synthesize an answer, upload files when needed, and keep the workflow light enough for regular study, research, and information gathering. Felo is strongest for students, researchers, analysts, and knowledge workers who want a quicker answer-oriented search workflow without building developer tooling. It is weaker for readers who need a full citation manager, deep local offline knowledge bases, or a pure developer API search layer. Our grounded judgment is that Felo still deserves to be recommended when the real need is quick AI-assisted search and synthesis for everyday web research, not when the user only wants a broad entertainment chatbot or a fully technical search stack.
SiliconFlow
SiliconFlow is an AI capability platform for developers and enterprises that need fast, lower-cost access to language, speech, image, and video models through a production-oriented service layer. It is most useful when the real challenge is getting model power into products reliably instead of merely discovering which models exist.
