Knowji
Pros
- + Methodologically sound design in its lifetime: spaced repetition with visual, auditory and contextual mnemonics per word
- + One-time pack purchases ($3.99–$11.99 historically) instead of subscriptions, per directory records
- + Offline study after initial download, with progress and memorisation-prediction tracking
- + Content organised from elementary to graduate level with SAT/GRE/TOEFL and ESL packs
Cons
- - The company has closed: knowji.com is a parked domain as of 23 October 2026 and the official X account announced the shutdown
- - Orphaned App Store listings remain installable with no backend, no updates and no support
- - No pricing exists to quote — aggregator pages listing current Knowji subscriptions are stale scrapes
- - Coverage was primarily English vocabulary with no conversational practice
- - Learning data cannot be exported or recovered through any vendor channel now that the company is gone
Khanmigo
Pros
- + Holds the no-answers line: in my session it declined to give answers and stayed Socratic across repeated prompts
- + Free for teachers at time of writing, with lesson planning, rubrics and student-work summaries included
- + Learner plan is $4/month or $44/year at time of writing, with a family variant adding child accounts and moderation alerts
- + Writing coach debates and probes evidence rather than rewriting student work
- + Voice input and read-aloud make it usable for younger students and accessibility needs
Cons
- - Self-serve access requires a US billing address; under-18s must join through a parent account
- - Curriculum alignment is US-centric (Common Core, AP, SAT); other national syllabi get a general tutor
- - Deliberately slow versus answer engines; students seeking quick homework answers will quit
- - Advanced undergraduate-level depth was uneven in my testing
- - No published learner free tier for the tutor itself; district pricing is quote-only
