; }; The browser extension puts MemoryPlugin directly inside the AI sites you already use. It injects a small panel into the page so you can read and add memories, pull context from past chats, and sync your conversation history, all without leaving the chat. It works across 21+ platforms and is the most complete way to use MemoryPlugin. ## Browser Compatibility Works with all Chromium-based browsers: * Chrome * Arc * Opera * Microsoft Edge * Vivaldi * Brave * [Quetta Browser](https://play.google.com/store/apps/details?id=net.quetta.browser) (Android) * And other Chromium derivatives Available for Safari on: * iOS (iPhone and iPad) * macOS (Mac computers) Install the extension using the links below, or find them on your [MemoryPlugin Dashboard](https://memoryplugin.com/dashboard) after signing up. Account email independence: Your MemoryPlugin sign‑in email does not need to match the email you use on ChatGPT, Claude, TypingMind, or any other tool. Access and permissions are tied to your MemoryPlugin account (and API key when applicable), not third‑party logins. ## Installation Install for Chrome and Chromium-based browsers Install for Safari on iOS and macOS After installation, sign up or log in to your [MemoryPlugin Dashboard](https://memoryplugin.com/dashboard) to start using the extension. ## The Panel On a supported site you get a round MemoryPlugin button floating on the page. Drag it anywhere; the extension remembers its position per site. Above it sits an **Add Memories** pill (it reads **Login** when you are signed out). Click the button to open the panel. The header shows **MemoryPlugin**, your plan badge (**CORE**, **PRO**, or **PRO LT**), a dark-mode toggle, and a close button. MemoryPlugin extension panel showing the General bucket, three memories, and the bottom tab bar with Memories, Sync, History, Account, and Settings MemoryPlugin extension panel showing the General bucket, three memories, and the bottom tab bar with Memories, Sync, History, Account, and Settings Under the header is the **Bucket** row: a dropdown that defaults to **All Memories**, plus a **Smart Mode** toggle that turns on Smart Memory for the current chat, for token-efficient loading (see [Smart Memory](#smart-memory)). A tab bar runs along the bottom of the panel: * **Memories** - view, add, edit, and delete memories in the selected bucket. * **Sync** - background sync of your chat history (only when Chat History is enabled; a `!` badge appears when more than 100 chats are unsynced). * **History** - open the Chat History search modal (also `Cmd+Shift+K` / `Ctrl+Shift+K`). * **Account** - your plan, stat tiles (Memories, Buckets, Chats, Messages), and links to the dashboard and help. * **Settings** - recall, auto-add, load limits, sync toggles, and the onboarding tour. ### Memories tab The Memories tab lists the memories in your selected bucket. Use **Add** to write one by hand, or the overflow menu for **Refresh memories**, **Copy memories**, **Export chat**, and **Load limit**. Each memory has inline edit and delete. When a bucket is empty you get a prompt to add your first memory or let the AI save them automatically as you chat. ### Buckets Buckets are separate contexts for your memories. Switch buckets with the dropdown before you inject, so the AI gets the right context for the conversation. Every account starts with a **General** bucket; create more from the dashboard for work, projects, or anything else you want to keep apart. See [Memory Buckets](/features/memory-buckets) for the full model. ## Injecting Memories The extension does not inject memories on its own by default. Press the MemoryPlugin button to activate it for a chat, or turn on auto-add in Settings. Activating a chat pastes two things into the composer: 1. Your memories from the chosen bucket. 2. Instructions telling the AI what MemoryPlugin is and how to save new memories. Without this step the AI cannot read your memories or create new ones for that conversation. Depending on the platform, activation happens through one of two controls: * **Quick inject button** - a compact button inline in the composer where the platform's layout allows it. Its tooltip reads *"Inject Memories from chosen Bucket"*. * **Add Memories pill** - on platforms where the inline button doesn't fit, a glass **Add Memories** pill appears above the floating MemoryPlugin button instead. Add Memories pill above the MemoryPlugin floating button, next to the chat composer Add Memories pill above the MemoryPlugin floating button, next to the chat composer ### Auto-Inject in New Chats Turn on **Automatically add memories in new conversations** in Settings to skip the manual step. When you send your first message in a new chat, the extension shows an **Auto-injecting memories** prompt with a 5-second countdown and a **Cancel** button, then injects. Cancel if you do not want memories in that conversation. ## Adding New Memories Once a chat is active, the AI is told to save memories by emitting a marker line that the extension watches for: ``` to=memoryplugin&&memory=[memory text here] ``` On ChatGPT the marker uses `tool=memoryplugin&&memory=...` instead. The AI adds a memory in one of two cases: * **Automatic** - it decides something is worth remembering long term. * **Manual** - you explicitly ask it to remember something. AI adding a new memory with the special format When the extension detects and saves a new memory, it shows a confirmation toast (for example *Memory saved: "User prefers morning meetings"*). Memory saved toast reading: Memory saved: User prefers TypeScript and Next.js for new projects ### Save a highlight with "Extract memory" You do not have to wait for the AI to save something. Select at least 3 characters of text anywhere in a chat and a floating **Extract memory** pill appears. Click it, the label changes to **Extracting...**, and a toast confirms *Memory saved: "..."*. It is the fastest way to keep a specific line from a conversation.
