A lightweight Calibre alternative, built for reading
Calibre is the Swiss Army knife of ebook management. But if all you want is to open a book and read it — with highlights and notes that stick — it's a lot of desktop software to launch. Here's a lighter way.
Let's be fair to Calibre first: it's genuinely great, it's free, and for managing a big library it's hard to beat. It converts between formats, edits metadata, fixes broken EPUBs, and syncs to e-readers. If that's the job, keep using it.
The trouble starts when the job is just reading. Calibre is a program you install and launch, its built-in viewer feels like a utility, and annotating across PDF and EPUB isn't where it shines. Sometimes you don't want to manage a library — you want to read the thing in front of you and mark it up.
What ReadHere does instead
ReadHere is a reader, not a library manager. It opens in your browser, reads PDF and EPUB the same way, and keeps your highlights and notes in one place. Nothing to install, and your files stay on your device.
- Open and read — drag a file into a browser tab, no app launch.
- PDF and EPUB, annotated identically — four highlight colors, notes, and a per-book journal across both formats.
- Reading-first details — Light/Sepia/OLED themes, curated fonts, and your place saved automatically.
- Offline — open a book once and read it with no connection.
- Your storage — files stay local; with Pro ($10/yr) they back up to your own Google Drive.

|---|---|---|
| Install | Desktop app (Win/Mac/Linux) | None — runs in the browser |

You can use both
This isn't really either/or. Plenty of people keep Calibre for what it's best at — organizing a collection, converting formats, loading a Kindle — and reach for ReadHere when they actually sit down to read and annotate something. Export an EPUB or PDF from Calibre, drop it into ReadHere, and go.
How to switch (or just try it)
- From Calibre, save the book to disk as EPUB or PDF.
- Open ReadHere and drag the file in.
- Read, highlight, and take notes — no setup.
Common questions
Does ReadHere convert formats like Calibre?
No — it’s a reader, not a converter. It opens standard PDF and EPUB files. Keep Calibre for conversion and metadata; use ReadHere to read and annotate.
Can I manage a big library in ReadHere?
You get covers and reading-progress for the books you add, but it’s built around reading, not managing thousands of titles. Calibre is the better tool for heavy library management.
Is it free like Calibre?
Reading is free with no account. Pro ($10/yr) adds Google Drive backup and cross-device sync.
Will it work on my Chromebook or phone?
Yes. Anything with a modern browser works, which is where a desktop app like Calibre can’t follow you.
