Stashly

Inspiration

We’ve all been there, saving links in browser bookmarks, screenshots of stuff we want to remember, or random notes scattered across different apps. After a while, it just feels messy and disconnected.

That’s what made me build Stashly: a single, clean place where you can stash everything (links, files, notes) and actually find them later. Plus, it looks modern and feels personal.

What it does

• Stashly is basically your personal vault for digital clutter:

• Save links, notes, and files in one place.

• Get automatic link previews (titles, favicons, images, the whole deal).

• Open files and images right inside the app.

• Favorite and filter items so you don’t lose track.

• Switch between light/dark mode with Material 3 styling.

How we built it

• UI: Jetpack Compose + Material 3 for that modern, smooth look.

• Storage: Room Database for keeping everything persistent.

• Previews: Jsoup for scraping link metadata, Coil for images.

• Architecture: MVVM with coroutines + Flow for reactivity.

• Files: Android’s Storage Access Framework for picking and handling files.

Challenges we ran into

• Jsoup doesn’t always give nice metadata (YouTube links, for example, return half-baked titles).

• Some sites like Twitter just block scraping altogether.

• Handling content:// URIs from providers like Google Photos was tricky — previews didn’t always render.

• Getting previews for text, files, and links to look consistent across the app needed extra design tweaks.

Accomplishments we’re proud of

• Designed a clean, card-based UI that works for all types of content.

• Built custom progress indicators (both linear wavy and circular wavy!).

• File/image previews inside detail screens actually feel smooth.

• Navigation and state handling feels seamless across the app.

What we learned

• Went deep into Jetpack Compose components like Scaffold, FlowRow, and custom drawing.

• Learned how to wrangle Android’s ContentProviders + SAF for file URIs.

• Found the sweet spot between performance and UI (async image loading, metadata fetching).

• Discovered the limits of scraping and why APIs sometimes make more sense.

What’s next for Stashly

• Add cloud sync so stashes aren’t tied to just one device.

• Lock the vault with password/biometrics for private stuff.

• Richer previews (like YouTube thumbnails, Twitter cards, etc.).

• Backup/restore with import/export.

• a share to Stashly intent so saving from any app feels natural.
