Your PDFs, arranged for the moment you need them.

Put the PDFs you use together into a project, keep the pages you return to one tap away, and move between them without losing your place.

A free beta for iPad, iPhone and Mac is coming soon on TestFlight.

Tomebound on an iPad, showing the Owlbear’s stat block from the SRD, with the hotbar of saved pages along the bottom: Conditions, Actions, Cover, Fireball, Owlbear, Goblin Warrior and Traps.

The pages you keep going back to, one tap away.

Save a page to the hotbar and it stays along the edge of the reader, whichever PDF is open. This page has one too, at the bottom of your screen.

A page, or part of one: A destination can be a whole page or just the part you need, like one table or one stat block, framed to fill the screen.
Named your way: Give it a short name, and an icon and a color if you want them.
It stays where you saved it: Reading on never moves a destination. Where you are now is remembered separately.
Where you want it: Keep the hotbar at the bottom or the top, or collapse it to a small handle when you want the whole page.

A project, not a pile of files.

A project holds the PDFs you use together: a rulebook and an adventure, a textbook and the week’s readings, a report and the standards it cites.

Switch between them from the drawer. Each one remembers where you were in it.

The PDFs drawer open beside the page, listing the project’s two PDFs, SRD Rules and SRD Monsters.

One library for every PDF: Search and sort every PDF you’ve added, tag them, and add one to a project from there.
One file, many projects: A PDF is stored once however many projects use it, and each project keeps its own place, highlights and destinations in it.
Archive what’s finished: Put a project away when you’re done with it. It still opens, just as you left it.

Groups for the things that come in sets.

Gather related destinations behind one button, such as random tables, conditions or a chapter’s sources. Open the group, tap the page and you’re there.

The Conditions group open above the hotbar, listing eight conditions, each with its PDF and page.

Follow a link, then come back.

Jump to a destination, a search result or a link in the PDF, and Return takes you back to the exact spot you left, at the zoom you left it at. Back and Forward work across every PDF in the project.

The Fireball spell, opened from the hotbar, with a button at the bottom reading Return to page 60 in SRD Monsters.

Pin a place: Tap the corner of a page to pin it. However far you wander, one tap on the ribbon brings you back.
Recent places: The last few places you jumped from are in a menu, and picking one goes straight there.
Open where you left off: Close the app and open it tomorrow, and you’re on the same page, at the same zoom.

Find it without flipping.

When the page you need isn’t on the hotbar yet.

Search the whole project: Find a word in one PDF or in all of them at once. Results are grouped by PDF, and the words are marked on the page when you land.
Quick switcher: Press ⌘P, type a few letters, and open any PDF or saved page by name.
Contents and page thumbnails: Browse a PDF’s outline, or a grid of its pages when it has none.
Links that work: Links inside a PDF are followed, and a link to another PDF opens it when it’s in the project.

Mark it up. The PDF stays clean.

Everything you add is kept beside the file, never written into it.

Highlights: Select a passage and highlight it in the color you choose, with a short note if you want one.
Notes: Keep notes for the project, each linked to the page it’s about. Earlier versions of a note are kept.
Apple Pencil: Write and draw on any page on iPad, or with a finger on iPhone. It works on scans and maps too.
Undo: Deleting something you wrote asks first, and ⌘Z brings it back.

Gamebooks and solo adventures.

Tomebound recognizes a book made of numbered entries and reads it the way you play it.

Go to an entry by its number: Type 83 and land at the top of entry 83, even when several entries share a page.
Tap “go to 212”: References in the text take you to their entry, even where the book didn’t link them.
A trail of where you’ve been: Every entry you visit is kept in order, and a grid of entry numbers shows which ones you’ve seen.

A new edition doesn’t cost you your work.

Replace a PDF with its revised file and what you made comes along.

Highlights find their words: Each one looks for its passage in the new edition, wherever it moved to.
Saved parts of a page follow: A destination that framed a table still frames it, and drawings move with their page.
Nothing is guessed: Anything Tomebound can’t place with confidence is kept and says so. The old edition stays in your library.

On all your devices, and nobody else’s.

Everything you make syncs: Your projects, hotbar, notes, highlights and drawings sync through your own iCloud to your iPad, iPhone and Mac. Turn on Sync PDFs, and the PDFs go with them.
