## 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

## Tactiq

Tactiq is an AI meeting assistant delivered primarily as a Chrome extension. It transcribes meetings live in Google Meet, Zoom, and Microsoft Teams without a bot appearing in the call, then produces summaries, action items, and follow-up content from those transcripts. Speaker identification and support for over 60 languages make it practical for international teams, and the extension reports over a million installed users.

Beyond raw transcription, Tactiq focuses on what happens after the meeting. One-click AI summaries and custom AI prompts turn a transcript into structured notes, and reusable prompts let you standardise the questions you ask of every meeting. AI workflows can trigger automatically and share insights into Slack, Notion, Linear, and HubSpot, while a verified connector in Claude's directory, a plugin in ChatGPT's directory, and an MCP connector help route meeting history into the AI tools a team already uses.

Tactiq is free to add to Chrome and works at a basic level on the free plan, with paid plans for higher usage and advanced features like workflows and enterprise controls. Privacy is a central selling point: Tactiq says it does not record or store meeting audio, the transcript is only visible to the user unless they choose to notify others, and it cites ISO 27001 certification, SOC 2 Type II attestation, and GDPR and HIPAA compliance.

**Pricing & Plans:** Freemium: the Chrome extension is free to install and use at a basic level, with paid plans for higher limits and advanced features; check the pricing page for current tiers.

- **Bot-free live transcription:** Real-time transcription in Google Meet, Zoom, and Microsoft Teams without a bot joining the call, with speaker identification.
- **Instant summaries and Ask AI:** Generate meeting summaries and action items in one click, or ask AI your own questions during and after the call.
- **AI workflows and integrations:** Create reusable prompts and automations that push meeting insights to Slack, Notion, Linear, HubSpot, and other tools.
- **Works with Claude, ChatGPT, and MCP:** Tactiq is a verified connector in Claude's directory, a plugin in ChatGPT's directory, and offers an MCP connector for your meeting history.
- **Security and compliance:** Tactiq cites ISO 27001 certification, SOC 2 Type II attestation, and GDPR and HIPAA compliance, and does not store meeting audio.

**Strengths:** No bot joins the call, so meetings stay natural; Live transcription plus one-click summaries and action items; Works across Google Meet, Zoom, and Microsoft Teams in 60+ languages; Verified Claude and ChatGPT connectors plus MCP and workflow integrations

**Limitations:** Requires the Chrome extension, so browser choice is limited; Advanced workflows and higher usage sit behind paid plans; Focused on meetings rather than being a general note-taking system
