## 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

## Merlin AI

Merlin is built around a simple idea: instead of opening a separate chat tab for every task, you summon one assistant with a click while staying inside whatever you are reading or working on. The extension injects a sidebar on any web page, so it can read the article, the PDF, the YouTube transcript or the Gmail thread you currently have open and respond with that context already loaded. That makes summarization, rewriting, replying and research feel like part of the page rather than a separate tool.

Under the hood Merlin routes requests across a broad set of models — OpenAI's GPT family, Anthropic's Claude, Google's Gemini, DeepSeek, Mistral, Meta's Llama and others — so you can pick the model that suits a task without holding separate subscriptions for each. Beyond chat there is an image generator with multiple models and aspect ratios, a search mode that answers questions from live web results, document and video summarization, and a library of saved prompts. Newer additions like Projects (reusable knowledge bases) and Crafts (generated diagrams, mind maps and charts) push it toward light research and prototyping work.

Merlin is available as a Chrome extension, a web app, an iOS app and an Android app with synced history, custom prompts and custom bots across devices. The vendor highlights GDPR, ISO 27001 and SOC 2 alignment for data handling, and positions itself as accessible in 200+ countries where some other assistants are restricted. It is squarely a productivity assistant rather than a developer platform.

**Pricing & Plans:** Freemium. A free tier covers everyday use, and Merlin Pro is promoted at $2/month as a special offer, with the standard plan advertised around $19/month billed annually and described as replacing roughly $130/month of separate AI subscriptions. Paid tiers add higher limits, more capable models and advanced features.

- **Multi-model access in one place:** Switch between GPT, Claude, Gemini, DeepSeek, Mistral and Llama class models from a single interface instead of juggling separate subscriptions.
- **Universal page summarization:** Summarize articles, YouTube videos, PDFs and documents in place, then ask follow-up questions grounded in that content.
- **Writing and social drafts:** Draft and reply to emails in Gmail, compose posts and comments for X and LinkedIn, and repurpose web pages or videos into blogs and articles.
- **Image generation:** Generate images from prompts using more than 20 image models and multiple aspect ratios for web and social output.
- **Projects, Crafts and custom bots:** Build reusable knowledge bases, generate diagrams and charts from a prompt, and assemble custom chatbots from your own instructions and context.

**Strengths:** Replaces several separate AI subscriptions with one interface and one bill; Works inline on any page, so context is captured without copy-pasting; Covers a wide range of tasks: chat, summarization, writing, images, search and light research; Syncs across browser, web, iOS and Android with custom prompts and bots preserved

**Limitations:** The free tier is limited, and heavy use pushes you toward the paid plan; Covering so many features means individual tools may be less deep than dedicated apps; Requires trusting a third party with the pages and documents you send it, even with the stated compliance certifications
