## 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

## mymind

mymind bills itself as "the extension for your mind." The core idea is frictionless capture: you save notes, links, images, quotes, articles, PDFs and even short videos with a click or a tap, and the app figures out the rest. There are no folders to design and no tag taxonomies to maintain — the platform detects whether an item is an article, a product, a book or a recipe, then files it visually so your saved library looks more like a mood board than a filing cabinet.

The AI layer is what replaces manual organization. On paid tiers you get automatic image tagging, text recognition inside screenshots and memes, article and PDF summaries, and Smart Spaces that group related saves around a theme without any setup. Search is deliberately associative: you can look for something by color, brand, keyword or approximate date, which mirrors how people actually recall things. Mastermind subscribers also get Reading Mode, full article backup even if the source disappears, bidirectional linking between notes, and video uploads up to 500 MB each.

mymind leans hard into privacy as a differentiator. There are no social features, no vanity metrics, no ads and no data selling; the company describes itself as a small indie team with no outside funding whose work is paid for entirely by members. Apps exist for iOS, Android, macOS and major browsers, with syncing across all of them. Pricing is straightforwardly subscription-based, with a basic Bookmarker tier for people who just want beautiful bookmarks and no AI.

If you need team collaboration, shared workspaces or enterprise admin controls, mymind is intentionally the wrong tool — it is designed for one person's private mind.

**Pricing & Plans:** Subscription with a free trial. The Bookmarker is $4.99/month; Student of Life is $7.99/month or $79/year; Mastermind is $12.99/month or $129/year (yearly saves roughly 20%). A not-yet-released "Newton" plan at $299/year is listed as in development.

- **Zero-organization saving:** Save notes, links, quotes, images, articles, PDFs and videos in one click, and let mymind categorize them automatically instead of building folder structures.
- **Associative visual search:** Find saved items by color, brand, keyword or date. Image text recognition even lets you search words that appear inside screenshots, memes or handwriting.
- **AI tagging, summaries and PDF analysis:** Images get tagged automatically, and Mastermind members get paragraph summaries of articles, web pages and PDFs so old saves are still useful months later.
- **Smart Spaces and Same Vibe:** Smart Spaces auto-group saves around a search, theme or tag, while Same Vibe builds a mood board from images you already saved with a similar look and feel.
- **Private by design, synced everywhere:** No ads, no analytics-driven feeds, no data selling; your library syncs instantly between iOS, Android, macOS and browser extensions.

**Strengths:** Removes the ongoing chore of folders, labels and tag upkeep; Strong privacy stance with no ads, no social layer and an explicit no-data-selling promise; Excellent associative recall through color, brand, keyword and in-image text search; Native apps for iOS, Android, macOS and all major browsers with reliable cross-device sync

**Limitations:** Paid-only beyond the trial — there is no permanent free tier; Built for individuals, so no shared workspaces, team permissions or collaboration features; Blue-chip AI features such as summaries, article backup and video upload require the higher Mastermind plan
