Support Sibyl
Everything online now comes with a meter attached. Sibyl doesn’t. Search deeply, follow every recommendation, build your library, and use the whole site. If Sibyl proves valuable to you, becoming a Supporter helps keep it that way for everyone.
Core discovery is free for readers everywhere. No ads, credits, daily discovery allowance, or essential discovery features held behind a paywall.
Support is voluntary. You’re funding an independent, human-run book-discovery project—not buying basic functionality back. Memberships help cover the cost of running and improving Sibyl.
