Gemini Reading Assistant

Support & FAQ

Last updated: 2026-04-18 · Version 3.0.3

Getting started

How do I install the extension?

Install from the Chrome Web Store. After installing, open gemini.google.com and refresh the page. The sidebar appears on the right once a conversation is loaded.

I installed it but nothing shows up. What's wrong?
  • Make sure you are on gemini.google.com (not bard.google.com or another URL).
  • Refresh the page after installing or after updating the extension.
  • Click the extension icon and confirm the master toggle ("Enable on this tab") is ON.
  • If the page loaded before the extension was ready, close and reopen the tab.
Which browsers are supported?

Any Chromium-based browser that supports Manifest V3: Chrome, Edge, Brave, Arc, Vivaldi, Opera. The extension is distributed via the Chrome Web Store; on other Chromium browsers you may need to install in developer mode.

Using the extension

What are the keyboard shortcuts?
  • CtrlF — in-page keyword search (enhanced Ctrl+F)
  • CtrlShiftS — open / close full-text conversation search
  • CtrlShiftX — open screenshot mode menu (NEW in v3.0.3)
  • Esc — close any open overlay (search, screenshot, etc.)
Why can't I type Chinese / Zhuyin into the search panel?

This was fixed in v3.0.3. Please update the extension via Chrome Web Store. If you are on v3.0.3 and still see the issue, please open an issue on GitHub with your Chrome version, IME, and OS.

My exported TXT file shows garbled characters on Windows Notepad.

This was fixed in v3.0.3 by prepending a UTF-8 BOM to exported files and normalising Unicode math-bold characters back to ASCII. Please update to v3.0.3. Markdown exports keep emoji intact by design.

How do screenshots work? Are my images uploaded anywhere?

No uploads, ever. The screenshot feature uses Chrome's built-in chrome.tabs.captureVisibleTab API. Captured images are processed entirely in your browser and downloaded as PNG files to your Downloads folder. See the Privacy Policy for details.

Three modes available via CtrlShiftX:

  • Region — drag a rectangle to select
  • Element — hover to highlight a block, click to capture
  • Long scroll — auto-scrolls the conversation and stitches segments into one tall PNG
Long screenshot stops at some point. Why?

Chrome has a hard Canvas size limit around 32,000 pixels. When your conversation exceeds that, the Extension caps the output height at 32,000 px and shows a toast notice. For extremely long conversations, use the conversation export (MD/TXT/JSON) instead, or capture in chunks.

Can I export my data?

Yes. Open the popup and click:

  • Export MD / TXT — conversation snapshot in human-readable form
  • Export JSON — full backup of all extension data (settings, cards, journals, license metadata)

The JSON export can be re-imported on another device via the Import JSON button.

Pro version

How do I purchase Pro?

Pro licenses are sold via Gumroad: gumroad.com/l/hsiowq. After purchase you receive a license key beginning with GRA-PRO-. Paste it into the popup's license field and click "Activate".

What do I get with Pro?
  • Critical Condense — let the AI surface logical gaps
  • Weighted Memory Pins (phase / core tiers)
  • Recall — one-click re-inject all pinned anchors
  • Context Usage Meter
  • Snapshot Handoff — carry context into a fresh conversation
  • Gemini plan selector (Flash 32k / Pro 128k / Ultra 1M)
  • Custom condense prompt
  • Unlimited store search (Free: 20 results)
I lost my license key.

Log in to Gumroad with the email you used to purchase; your license is shown in the order details. If you need help, contact Gumroad support or open an issue on GitHub.

Can I use Pro on multiple devices?

Yes. The same license key can be activated on all your personal devices. The verification just confirms the key is valid; there is no hard device cap enforced by the Extension.

How do I cancel / refund?

Gumroad's standard refund policy applies (30 days from purchase, case-by-case). See Terms of Use for details.

Troubleshooting

The sidebar doesn't update when Gemini streams a long answer.

This can happen if Gemini's DOM structure changes. Try: (1) refresh the Gemini tab, (2) click the extension's "Refresh Diagnostics" button in the popup, (3) if the issue persists, report it on GitHub with your Chrome and Gemini page URL.

Search finds nothing even though the text is clearly in the conversation.

The search uses the internal message store, which is built as messages load. For very old messages that loaded before the extension was active, click Full Backfill in the popup to force a full re-scan, then search again.

The Pro license stops working after 30 days.

The Extension re-verifies Pro licenses in the background every 30 days (with a 7-day grace period). If re-verification fails because you are offline, try again when online. If the license was revoked upstream (unlikely), contact support.
