## ChatHub

ChatHub solves a simple but persistent problem: any single language model can be wrong, and switching between separate chat tabs to cross-check an answer is tedious. Instead, the app sends one prompt to several models simultaneously, then lays their responses side by side so you can spot agreements, contradictions, and gaps at a glance. Supported models span the major commercial families plus open-weight options, and the same account gives access through a single subscription rather than a stack of separate AI plans.

Beyond model comparison, ChatHub bundles practical assistant features: document and image upload for analysis, web search for real-time information, code snippets with syntax highlighting and live preview, an image generation workspace using popular diffusion and image models, a searchable prompt library, and built-in translation and web summarization tools. The interface is deliberately familiar, resembling a standard chat UI with a model picker, so the learning curve stays short.

ChatHub is available as a web application, a Chrome browser extension, iOS and Android apps, and desktop clients for Windows and macOS, which makes it easy to move between devices or work alongside whatever page you are reading. A free tier covers basic use, while heavier usage and premium features require a paid plan; consult the pricing page for current limits.

**Pricing & Plans:** Freemium. A free tier covers basic usage; premium plans unlock more usage and advanced features such as higher message limits and additional models. See the official pricing page for current tiers.

- **Side-by-side multi-model chat:** Send one prompt to several leading chatbots at once and compare answers in parallel to spot hallucinations and disagreements.
- **One subscription for many models:** Access the latest commercial models plus open-weight options through a single plan instead of juggling separate subscriptions.
- **File upload and web search:** Attach PDFs, spreadsheets, and images for AI analysis, or pull in real-time information from the web when you need current facts.
- **Image generation workspace:** Generate artwork, illustrations, and photos using popular image models without leaving the chat interface.
- **Apps across every device:** Use the web app, Chrome extension, iOS and Android apps, or Windows and macOS clients, with a prompt library and code preview built in.

**Strengths:** Genuinely useful parallel comparison that reduces reliance on a single model's output; One subscription and one interface for many different AI models; Available on web, browser extension, desktop, and mobile; Includes extra tools such as image generation, prompt library, translation, and web summarization

**Limitations:** Requires internet access and depends on third-party model providers being available; Full model access and higher usage limits sit behind paid plans; Multi-model answers consume more tokens and quota than a single chat, so usage can add up

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
- **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
