Frequently Asked Questions

Setting up sync across your devices, and getting the most out of Research Sync.

Syncing your devices

Research Sync has no accounts and no sign-in. A private sync key is what links your devices together — this is the one setup step almost everyone needs.

How do I get my devices to share one list?

Every install — the app, each browser extension — generates its own random sync key the first time you open it, and starts out as its own private, unconnected list. To link two devices, you copy the key from one and paste it into the other:

  1. On your first device, open Settings (the gear icon) and find Sync Key. Tap Copy Key.
  2. On your next device, open its Settings, paste the key into the Sync key field, and tap Save key.
  3. Repeat for every additional device or browser you want on the same list.

Once two clients share a key, anything you save, read, delete, or sort on one shows up on the others within a minute or so.

Where exactly do I find the sync key screen?

iPhone / iPad Tap the gear icon in the top-right corner of the main list.

Browser extension Click the extension icon, then the gear icon in its popup header.

Safari (Mac) Same as above — open the extension popup, then Settings.

I already had items saved on the second device — what happens to them?

They're not lost — pasting a key merges lists rather than replacing one with the other. The first sync after you paste a new key uploads whatever was already on that device and combines it with the key's existing list, so you end up with everything from both.

Tip: if you're setting up a brand-new device and don't want any pre-existing items mixed in, paste the key before saving anything on it.
Is it safe to share my sync key? Can I recover it if I lose it?

Treat your sync key like a password — anyone who has it can read and edit your saved list. It's fine to store it in a password manager or paste it between your own devices; just don't post it publicly.

There are no accounts, so there's no "forgot my key" recovery. If you lose every device that has it, that list is unreachable. Keeping a copy somewhere safe is worth doing once, right after you generate it.

The basics

Saving, filtering, and everyday reading.

How do I save a page?

Browser Click + Save in the extension popup, or use the keyboard shortcut (set one under the extension's shortcut settings).

iPhone / iPad Use the Share Sheet from Safari or any app, or ask Siri / use the Shortcuts app.

Safari (Mac) Click the extension's toolbar button on the page you want to save.

What's the difference between All, Unread, and Read?

Unread is the default view — it's your reading queue, and it's what you'll see most often. Read shows things you've already gotten to, in case you want to find something again. All shows everything except items you've deleted.

Opening a saved link marks it read automatically. You can also toggle read/unread manually without opening it — swipe on the item, or use the checkmark button.

Can I add my own notes to a saved link?

Yes — tap the note icon on any item to jot down why you saved it. Notes sync along with everything else, so they show up on every linked device.

How does offline reading work?

Tap the download icon on a saved item to capture a readable, offline copy. Once it's ready (the icon turns into an open book), you can read the full article with no connection — even on a different device than the one that saved it, since the copy syncs too.

Article bodies are end-to-end encrypted before they ever leave your device, so only your synced devices can read them — not the server in between.

How do I search my list?

Use the search box at the top. It matches against both the title and the URL, and it always shows a flat, ungrouped list of every match — so if you have folders on, search temporarily sets them aside rather than making you dig through collapsed sections.

What happens when I delete something?

It's removed from every device on your sync key, along with its offline copy if it had one. Deletion syncs like everything else — there's currently no "recently deleted" recovery, so it's final.

Folders

Saved links get sorted into folders automatically — no filing required.

How does automatic sorting work?

Shortly after you save something, it's assigned a folder based on its title and web address — things like "Politics," "Recipes," or "Tech" get grouped together on their own. You don't create folders by hand; they're generated as your list needs them, and reused for similar items.

Privacy: sorting only ever looks at the title and URL. It never sees the article's actual content, which stays end-to-end encrypted the same way offline copies do.
How do I turn folders on?

Tap the folder icon next to Settings to switch between a flat list and folders. This is a per-device setting — turning it on in the iPhone app doesn't change what you see in the browser extension, and vice versa. Use whichever view suits each device.

Can I collapse folders I don't need to see right now?

Yes — tap a folder's name to collapse or expand it. The number on the right tells you how many items are inside without needing to open it, and your collapsed/expanded choices are remembered the next time you open the app.

What does the little "Sorting…" spinner mean?

It shows up right after you save something, while a folder is still being figured out — this usually takes a few seconds. If you keep the app or extension open, it resolves on its own; you don't need to refresh or do anything.

What's the small dot on a folder header for?

If a folder is collapsed and something new just got sorted into it, a small dot appears on that folder's header — so you know to check it without opening every section to look for what's new. It clears once you expand that folder.

Everything else

Can I get my data out?

Yes — Settings has Export as JSON and Export as CSV, both including your notes and folders. There's no lock-in.

Which browsers does the extension work in?

The Chrome Web Store extension works in any Chromium-based browser — Dia, Chrome, Edge, Arc, and Brave all use the same install. Safari uses a separate native extension (downloaded as a Mac app) because Safari doesn't support the Chrome Web Store version.

Can I change the color theme?

Yes — pick from the color swatches in Settings. Theme choice is per-device, like folders, so each install can look different if you'd like.
