Features & Capabilities

SyncNos is a local-first, open-source browser clipper for AI conversations, web articles, and video transcripts.

Capture useful content while keeping local browser storage as the source of truth:

Save supported AI conversations.
Extract readable content and relevant metadata from web pages.
Capture YouTube and Bilibili transcripts/subtitles, including timestamps when available.
Review and organize captured content locally before deciding where it goes next.

Choose what happens next:

Sync manually or automatically to Notion, Obsidian, Feishu (Lark), or GitHub.
Export selected items as Markdown or JSON.
Create a local Backup ZIP for recovery.

SyncNos also supports article annotations, saved-item mentions in supported AI chats, browsing saved content, and an Insights view.

Privacy is part of the architecture: captured content is stored locally first. External transmission happens only when you configure or invoke a sync or export destination.

Is SyncNos-WebClipper Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SyncNos-WebClipper requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

SyncNos-WebClipper may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
