Hub
Status: LiveA web and workspace search engine that also launches every app in Hollow.
Hub is Hollow’s home base: one search bar that reaches across your own workspace and a curated, constantly refreshed slice of the web, with every other app one click away.

Search
One bar, two indexes
Hub’s search bar queries two indexes at once: your own workspace documents from Notes, Workbooks, Slides, Diagrams, and more, and a separate, curated index of the web, built on PostgreSQL full-text search and ranked by relevance and recency.
- Searches your Hollow content and the web from one bar
- Built on PostgreSQL full-text search, not a black-box vendor API
- Results ranked by relevance, ties broken by recency
- Your workspace content
- A curated web index
- Full-text search
- Ranked by relevance and recency
Crawl
A web index that keeps itself honest
The web index is built by a daily, breadth-first crawl of a curated site catalogue, respecting robots.txt and per-domain rate limits, with automatic clean-up so removed or stale pages don’t linger in results.
- Daily crawl across a curated site catalogue, grouped by re-crawl interval
- Depth and page caps keep the index focused, not a blind web scrape
- Automatic clean-up evicts stale or removed pages
- Daily automatic crawl
- Respects robots.txt
- Per-domain rate limits
- Stale pages self-clean
Launch
Every app, one click away
Hub is also the front door to every other app in Hollow, and it can turn a YouTube link into a full transcript saved straight into your notes, using Gemini’s native audio understanding rather than a separate transcription vendor.
- One click through to every app in the suite
- Paste a YouTube link, get a saved, readable transcript
- Live progress as a video is analysed, downloaded, and transcribed
- Every Hollow app
- Transcribe a YouTube link
- Saved straight to Notes
- Gemini-native transcription
