## 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

## Poe

Poe is an AI chat platform created by Quora. Instead of subscribing to each frontier model separately, you get a single interface where you can switch between models from OpenAI, Anthropic, Google, Meta, xAI and others, plus image, video and audio generators. The home feed lets you explore and use bots created by other people, so you can try specialized assistants for writing, coding, research, translation, roleplay or image creation without setting anything up.

A key part of Poe is bot creation. Anyone can build a custom bot by writing a prompt, choosing a base model and optionally attaching knowledge files, then publish it for others — or keep it private. Conversations, bots and settings sync across web, iOS, Android, Windows, Mac and Linux clients, so Poe works as a general-purpose daily AI assistant rather than a single-purpose tool.

Pricing is freemium: a free tier gives limited daily message allowances across a subset of models, while a paid subscription unlocks higher limits, access to more capable premium models, larger uploads and bonus compute points. Because the model catalog and quota rules evolve quickly, check the official Poe site for current plans and usage limits.

**Pricing & Plans:** Freemium: a free tier offers limited daily usage across many models, while paid subscriptions raise message limits and unlock premium frontier models, bigger uploads and bonus compute points. Check the official site for current plans and limits.

- **Multi-model chat:** Talk to GPT, Claude, Gemini, Grok and many other text, image, video and audio models from a single chat window.
- **Custom bot builder:** Create your own bots with a prompt and a base model, then share them publicly or keep them private.
- **Explore community bots:** Browse thousands of bots made by other users for coding, writing, research, study, roleplay and more.
- **Cross-platform sync:** Your chats, bots and settings stay in sync across web, iOS, Android, Windows, Mac and Linux clients.
- **Multimodal generation:** Generate and analyze images, video and audio alongside text in the same conversation.

**Strengths:** Access to many leading models through one login and subscription; Powerful bot creation and sharing without coding; Syncs across web, mobile and desktop clients; Continuously adds newly released frontier models

**Limitations:** Free tier message limits can be reached quickly with heavy use; Premium models and higher quotas require a paid subscription; Feature and quota rules change frequently as models update
