## MemBrain - AI-powered Second Brain

MemBrain is a Chrome extension that places an AI assistant in the browser's side panel. Rather than switching tabs to a chat website, you can open the panel and talk to an AI model while the page you are reading stays visible next to it. It is positioned as a lightweight 'second brain' for research and browsing, and the project is open source.

The extension focuses on flexible context. You can add one or more web pages, or selected passages of text, as references for the model, so answers are grounded in the material you are actually looking at rather than generic knowledge. It ships with integrations for several popular AI providers and models, and because it is built around standard API formats you can add further providers or models yourself. Prompt templates can also be saved so common tasks are one click away.

Privacy is a stated design principle: the extension runs without any intermediary server and communicates directly with the model providers using the API keys you supply. According to the developer, it does not collect, store, or share personal information, browsing history, API keys, or chat history. MemBrain is distributed through the Chrome Web Store and is free to install.

**Pricing & Plans:** Free. MemBrain itself is a free, open-source Chrome extension; costs come from the AI provider API usage you pay for directly with your own API keys.

- **AI chat in the Chrome side panel:** Open an AI chat alongside the page you are reading, without navigating away or switching tabs.
- **Web pages and text as context:** Attach one or more pages, or selected passages, as references so answers draw on your actual source material.
- **Bring your own API keys:** Connect directly to providers such as OpenAI, Anthropic, and Google using your own keys, and add more providers that follow supported API formats.
- **Reusable prompt templates:** Save prompt templates to run frequent tasks in a single click.
- **No intermediary server:** The extension talks straight to model providers and, per the developer, does not collect or store your data, keys, or chat history.

**Strengths:** Keeps AI chat in the browser side panel next to your content; Supports multiple AI providers through user-supplied API keys; Open source and, per the developer, operates without a backend server; Custom prompt templates and self-added models add flexibility

**Limitations:** No bundled AI credits, so you must set up your own provider API keys; Very small install base, so community support and documentation are limited; Last listed update is v0.4, so the release cadence appears slow

## Typing Mind

Typing Mind positions itself as "the best frontend for AI" — a polished client layer that sits between you and the underlying models. Rather than locking you into one provider, it lets you add your own API keys for ChatGPT, Claude, Gemini and any other LLM, then switch between them in a single chat interface. That bring-your-own-key model means there is no monthly subscription to the app and no usage cap imposed by it; you pay the model providers for what you actually consume.

The feature set has grown well beyond a simple chat window. There are project folders to keep dedicated workspaces with their own chat history, knowledge bases and instructions; conversation threads and forked chats; full-text search, tags and filtering over your history; Canvas and Artifacts for interactive, editable outputs; document chat and RAG so models can work over your own files and sources such as GitHub, Notion or Google Drive; web search and deep research; voice input and text-to-speech; and MCP connectors. A comprehensive agent builder lets you create custom agents, chain prompts and attach plugins such as Slack notifications or calendar access.

Privacy is a central selling point: chat history is kept in local browser storage and the company says it collects no data for AI model training. TypingMind is available as a web app and a Chrome extension, and the company says more than 20,000 customers use it daily.

**Pricing & Plans:** Paid. Typing Mind is sold as a one-time lifetime license rather than a subscription, with a limited-time discount deal frequently on offer and a free trial available. You also pay your chosen AI providers directly for API usage. Team and custom deployments are offered separately.

- **All models in one place:** Plug in ChatGPT, Claude, Gemini and other LLM APIs and switch between them in a single interface, comparing responses side by side.
- **Bring your own API key:** Bring your own keys and pay only for actual usage — Typing Mind is sold as a license rather than a recurring subscription.
- **Private local storage:** Chat history and settings are stored locally in your browser, with no data collection or use for model training by the app.
- **Agents, plugins and prompt chaining:** Build custom AI agents, chain prompts, add training files, connect live APIs and extend functionality through a plugin library.
- **Modern workspace features:** Advanced tools include Canvas and Artifacts, RAG over documents, web search, deep research, text-to-speech, voice input, vision and MCP connectors.

**Strengths:** One interface for ChatGPT, Claude, Gemini and other LLM APIs; No monthly app subscription and no usage caps imposed by the client; Local-first storage with a strong privacy stance; Extensive feature set: agents, plugins, RAG, Canvas and deep research

**Limitations:** You must supply and pay separately for your own API keys; It is a client layer, not a model — capabilities depend on the providers you connect; Advanced agent and plugin setup has a learning curve
