Amnesia — An EPUB and PDF reader for Obsidian

Skip to the product demonstration

Pre-alpha Amnesia for Obsidian

Keep your books closer to your thoughts.

Read EPUBs and PDFs inside Obsidian. Navigate the whole book, change how pages flow, highlight in place, and bring any selection into Markdown.

A zoomed Obsidian workspace demonstrates the real Don Quijote spine, multi-color highlights, a wikilink, and an EPUB selection embedded into a Markdown note.

01The reader in motion

Read the whole book, not a flattened preview.

Amnesia keeps EPUBs and PDFs at the center of the workspace, with navigation and page modes designed for long-form reading.

A reflowing Obsidian reader moves from an EPUB through four scroll-synchronized PDF viewing modes and finishes with a panning canvas beside a Markdown note.

02Obsidian, extended

Use the patterns you already know.

Bases, Workspaces, Canvas, ⌘E, and wikilinks keep behaving like Obsidian. Amnesia adds books to that vocabulary instead of sending you to a separate reading environment.

01Bases

Let the library organize itself.

A single Library Base becomes a set of native Card views. Move from Physics to Philosophy to Software Engineering without copying a catalog into a second app.

02Split views and Canvas

Put the source beside your notes.

Read a note, scan adjacent PDF pages, and place the same material on Canvas. The arrangement changes while the passage remains easy to reopen.

03Workspaces

Return to your reading layout intact.

Saved Workspaces restore a real book sidebar, PDF contents, worked notes, and a Bases query together. Each desk is shaped around the material instead of repeating one layout.

04Reading and Studying

One shortcut changes the job, not the page.

Reading keeps the interface quiet. Press ⌘E when the page needs regions, editing tools, and a more deliberate study mode.

05Wikilinks

Books can join the graph.

Select the exact words, choose a note from the native picker, and keep the relationship visible through Backlinks, Unlinked mentions, and Local Graph.

03Source-aware reading

Every excerpt can point back to the exact page.

An EPUB passage remembers its chapter and a PDF selection remembers its page. Your note stays ordinary Markdown while every excerpt keeps a route back into the reader.

01Source-linked notes

Create the note without closing the book.

Select the passage, create a note, and keep book and note in view. The note begins with a durable route back to the exact fragment that prompted it.

02Live PDF regions

Bring text and figures into the same note.

Select text from one PDF, insert it into Markdown, continue into a second book, and add a differently colored figure selection directly below it.

03Live collections

Build the index your research needs.

Turn highlights and annotations into queryable items, then shape custom collections around source, topic, status, or any property you track.

04Two formats, one reader

Keep what makes each source itself.

EPUB and PDF do not need the same internal model to participate in the same vault. Amnesia preserves the address each format can actually keep.

05Device dispositions

The reading desk travels.

The iPad keeps the familiar Obsidian shell and touch-sized reader controls. On the phone, the same EPUB reflows into a comfortable single column instead of shrinking the desktop page.

iPadThe chapter list and active page remain together, with the reading controls in reach.

PhoneDon Quijote keeps its type, tools, and reading progress while the prose fits the narrower measure.

On iPad, chapters stay beside the page while reading controls remain within reach.
On your phone, Don Quijote becomes a focused single column without losing its typography or your reading progress.
