## Chatbox

Chatbox is a multi-model AI client rather than a model of its own. Instead of locking you into a single provider, it connects to the APIs you already pay for — GPT, Claude, Gemini, Grok, DeepSeek and a long list of others — and gives them a single, consistent workspace. Because you supply the keys, your conversations run against your own accounts and quotas, and Chatbox states plainly that it does not sell or share your data. The app ships for Windows, macOS (Apple Silicon and Intel), Linux, iOS and Android, and there is also a browser version, so the same conversations and settings follow you between devices.

The everyday workflow is chat-plus-files. You can drop in PDFs, Word documents, spreadsheets, images and code snippets and ask questions about them, then quietly build a local knowledge base so the app remembers and retrieves your own documents over time. A live web search mode pulls current information for questions where the model's training cutoff is not enough, and the rendering layer handles Markdown, Mermaid diagrams and LaTeX formulas properly, which matters for technical and academic work.

More recently the product has been pushing beyond plain chat with Work Mode, an agentic layer where an assistant can work with your files, search the web, write and preview code and run tools with less babysitting. There is AI image generation for turning prompts into visuals, plus code generation with live preview for quick prototyping. A free tier covers standard use, and paid plans raise limits or add hosted features aimed at heavier users; the desktop app itself can still be used with your own API keys.

**Pricing & Plans:** Freemium: a free tier covers everyday chatting, with paid subscription plans that lift usage limits and add hosted AI capabilities. Bringing your own model API keys keeps costs tied to your provider.

- **Multi-model support with your own keys:** Switch between GPT, Claude, Gemini, Grok, DeepSeek and many other providers in one client by plugging in your own API credentials.
- **File, image and document Q&A:** Upload PDFs, Office documents, images and code, then ask the app to summarise, explain or extract what you need.
- **Local knowledge base:** Store documents locally so Chatbox can recall and answer from your own materials while your data stays on your machine.
- **Live web search and rich rendering:** Pull current results from the web and display answers with Markdown, Mermaid diagrams, LaTeX formulas and code previews.
- **Work Mode agents and image generation:** Let an agent handle multi-step tasks with your files and tools, and generate images directly from prompts.

**Strengths:** Supports many leading models in a single interface, so you are not locked into one provider; Available on Windows, macOS, Linux, iOS, Android and the web; Local knowledge base and clear privacy positioning keep your documents on your device; Handles files, images, web search, code preview, LaTeX and Mermaid out of the box

**Limitations:** Best experience with your own API keys, which means managing separate provider accounts and billing; Model availability and quality depend entirely on which providers you connect; The breadth of modes and settings can be overwhelming for someone who just wants a simple chat window

## 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
