The practical guide to compact on-device AI
Private model, clear tradeoff.Local inference keeps reading tasks private while first-run setup may take time.
Best fit: focused reading.Short factual summaries work best when the page contains enough text.
Caveat: verify facts.Generated answers can omit nuance, so important details should be checked.
Ask AI: "What are the main risks in this article?"
What it does
Summaries that are built for reading, not skimming noise.
Nano Summarizer extracts the active tab after your click and turns available content into clear bullet notes.
02
Ask about the tab
Use the side-panel chat to ask follow-up questions while keeping the current page as the primary context.
03
Multiple source types
Works with readable pages, Youtube-videos, text pdf-, txt-, markdown-, log-, csv-files.
Flow
One user action. One active tab. One focused result.
01
Click the extension
Nano Summarizer receives temporary access to the active tab only after you invoke it.
02
Extract page text
The extension reads available visible text, document text, metadata, comments, or table rows.
03
Run local AI
Supported Chrome builds use built-in browser AI to produce the summary or answer locally.
04
Keep reading
The side panel stays open for summary refreshes and follow-up questions.
Privacy
Designed without extension-side data collection.
Active-tab content and user questions are processed transiently for the requested result. The extension does not store extracted page text and does not send it to GagarinSoft servers.
- No broad host permissions. The extension uses temporary active-tab access after a user action.
- No cloud AI fallback. Summaries and answers use built-in browser AI on supported devices.
- No extension storage of page text. Extracted content is not persisted by Nano Summarizer.
- No sale or advertising use. The extension does not sell data or use it for ads.
Install
Free extension for easier reading.
Add Nano Summarizer to Chrome and keep a private reading assistant next to the page you are working with.
