Frequently Asked Questions

How fast does it sync?

Boox e-readers sync instantly via cloud push. Kindle devices receive articles in under 2 minutes via Send-to-Kindle email. Any e-reader with OPDS or WebDAV support can pull content on demand.

What e-readers work with LibSpace?

All Kindle models (Paperwhite, Scribe, Oasis, Basic), all Boox models (Note Air, Tab Ultra, Poke, Go), and any e-reader that supports OPDS, WebDAV, or email delivery.

Can I send RSS feeds to my Kindle?

Yes. Subscribe to any RSS feed in LibSpace, set up automatic delivery, and new articles arrive on your Kindle as clean EPUBs. You can also bundle your feeds into a daily Morning Brief.

Can I save paywalled articles?

Readwise is a reading app with highlights sync. LibSpace is a delivery pipeline — content shows up on the e-reader you already love. Different jobs.

How much does it cost?

30-day free trial, no credit card required. Then $4.99/month or $49.99/year. All features included, no premium tiers.
