The Private Index

YASE

Your private workspace inside YouTube.

YASE adds a private workspace inside YouTube: local search for saved videos, tags for what matters, and focused browser-side tools that keep your library easier to use without uploading it to a YASE server.

Launch notification

Choose Chromium, Firefox, or Safari. YASE sends one launch notification for that browser target. No newsletter, no product analytics, no Store placeholder links.

Supported browsers

Built for the browsers people actually use.

YASE ships as Chromium, Firefox, and Safari builds. Chromium-family browsers route to the Chrome Web Store once the listing is real; Firefox and Safari stay separate because they have dedicated builds.

What YASE does

A private layer for the YouTube you already use.

YASE is built around a private local index for saved YouTube videos, with tags, notes, and browser-side tools that make YouTube easier to manage in place.

Find videos without leaving YouTube

Find saved videos by title, channel, or tag straight from the YouTube tab you already opened.

Tag what matters

Add tags next to each saved video so the reason you kept it is one click away.

Stay local in your browser

Your saved-video index lives in your browser. Your playlists, tags, and notes do not ship to a YASE server.

Workflow

Open YouTube. Build the local index. Find what you need.

Use YouTube normally

YASE appears on supported YouTube pages and adds its tools where they are useful.

Build a local index

The extension indexes the metadata needed for search, tags, notes, and supported local features in the browser.

Search, tag, refine

Find what you kept, add context, and keep your YouTube workflow organized over time.

Coming next

Next: deeper YouTube customization.

Same archive. Same privacy. Next, YASE becomes a local control layer for how YouTube looks and feels.

Trust and review proof

Private by design, explicit where it matters.

The homepage stays focused on the product. Detailed data handling, permission rationale, and security boundaries live on dedicated pages that render without JavaScript.

No hidden analytics Privacy policy, Limited Use statement, local/server data inventory, and deletion route. Permissions explained Browser permissions, host permissions, OAuth scopes, and why each is needed. No remote code Security model, validation boundaries, and disclosure contact.

Limits

Transparent where it matters.

YASE depends on supported YouTube pages and browser APIs that may change.

Some actions require a browser tab signed into YouTube.

YASE is independent from Google and YouTube.

The public CTA stays in beta mode until a real Store listing exists.
