The Verdict
Anki is built for medical students and language learners, with a focus on spaced-repetition and custom-cards. Twenty targets startups and developers and leads with contacts-management and pipeline.
Twenty uses custom enterprise pricing, while Anki starts at $24.99/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Twenty offers broader built-in capabilities (7 features vs 6), while Anki takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Anki has a slight overall edge — but if completely open-source and free to self-host matters most to you, Twenty may still be the right call.
