User Guide

After installing SiderMem from the Chrome Web Store, click the extension icon in your toolbar to open the side panel. SiderMem works entirely in this side panel — it stays alongside your active tab so you can capture and review memories without leaving the page.

Using SiderMem without an account: You can start capturing memories immediately with no login required. Everything is saved locally in your browser. Local memories persist across browser sessions and are private to your device.

Creating an account (recommended): Tap the user icon at the top of the panel and enter your email address. SiderMem uses passwordless login — we send a one-time code to your email, which you enter to sign in. No password is ever created or stored. Before sending the code, you must confirm that you have read and agreed to the Terms of Service and Privacy Policy.

Once signed in, your account is linked to your email. You can sign in on any device and access your cloud-synced memories.

Your memory library is sorted by creation date, with the most recent at the top. Use the tab bar to filter by source type: All, Chat, Files, or Manual.

Search: Type in the search bar to instantly filter memories by title, content, or file name. The search is local and works without a network connection.

Starring a memory: Every memory card has a star icon to the left of the title. Click it to mark the memory as important. Starred memories are automatically moved to the top of the list. Multiple starred memories remain sorted by date among themselves. Click the star again to remove it. The star state is saved locally and synced to the cloud the next time you manually sync that item.

Card action buttons: Hover over a card to reveal the full set of action buttons in the top-right corner — from left to right: AI Summary, AI Reformat, Share, Sync, Copy, and Delete.

Status indicators (bottom bar): The four small icons at the bottom of each card show the current state at a glance — whether an AI summary exists, whether the content has been reformatted, whether the memory is publicly shared, and whether it is in sync with the cloud.

Editing a memory: Click anywhere on the card title or content area to open the editor. You can change the title, edit the content, or update the tags.

Deleting a memory: Hover over a card to reveal the action buttons, then click the trash icon. If the memory was synced to the cloud, the deletion is also pushed to the server on the next sync.

Cloud Sync is available to logged-in users. It stores your memories on SiderMem's cloud infrastructure so you can access them from any device.

Syncing a single item: Hover over a card and click the sync icon (circular arrows). The icon color tells you the current sync state:

• Green — in sync with the cloud
• Amber / spinning slowly — modified locally, not yet synced
• Red — a conflict was detected (both local and cloud were changed)
• Grey — never synced

Syncing all items: Tap the global sync button at the top of the panel to push all pending local changes to the cloud at once.

Storage limits: Free accounts can sync up to a limited number of memories. Pro and Ultra plans increase this quota. If your cloud quota is full, new syncs are blocked until you delete cloud memories or upgrade. Items over 128 KB in size cannot be synced regardless of plan.

AI features require a Pro or Ultra subscription and a logged-in account. Each action counts against your monthly AI quota, visible in the Account section.

Before running an AI action, check your preferences in Settings → AI Preferences. You can configure Summary Length (Brief or Standard) and Reformat Output format (Markdown or Plain Text).

Go to Settings → Export Data to download your entire memory library. Two formats are available:

• Single JSON File — exports all memories into one structured .json file. Best for backups or importing into other tools. Each memory includes its original content, AI-generated summary and reformat (if available), source metadata, and timestamps.
• ZIP Archive of Markdown Files — exports each memory as an individual .md file with YAML frontmatter (title, UUID, source, tags, timestamps). Fully compatible with Obsidian, Logseq, and other Markdown-based note-taking tools.

Exports include all local memories for your account, including those that have never been synced to the cloud. We recommend exporting regularly as a personal backup.

Ultra plan subscribers can publish individual memories as publicly accessible web pages. Anyone with the link can view the memory — including its original text and any AI-generated summary or reformatted version.

Enabling sharing: Hover over a card and click the share icon. The memory must already be synced to the cloud first. Once active, the share icon in the status bar turns green — click it to copy the public link to your clipboard.

Disabling sharing: Click the share icon again to toggle off. The public link becomes inaccessible immediately.

Sharing and inactive memories: If your cloud storage quota is exceeded and a memory is marked inactive, its public link is automatically disabled until reactivated.
