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
Readlang
Pros
- + One-click inline word and phrase translation kept my place in both a Spanish article and a French novel excerpt — no modal, no side panel
- + Flashcard queue prioritizes high-frequency words via frequency lists and spaced repetition; in my week of use it drilled reusable vocabulary, not one-off nouns
- + Premium at $48/year removes the free plan's 10-phrase/day and 200-word flashcard caps and is one of the smallest annual fees in the category
- + One subscription covers all supported languages (40+ listed), so studying two languages in parallel costs nothing extra
- + Import flexibility: browser extension and bookmarklet for any web page, plus paste/file upload for books and documents
Cons
- - Free plan phrase translations cap at 6 words per phrase and 10 per day — I hit the cap within twenty minutes of reading, and idioms get chopped up
- - No speaking or conversation practice, no grammar course, no CEFR curriculum: it is a reading tool, not a complete language program
- - Audio storage is paid-only (10 hours Premium, 200 Premium Plus; zero on free) and the TTS quality tier is gated behind subscription
- - Indie-scale support: no SLA, no phone support, no admin controls or institutional plan for schools or procurement
- - Feature discoverability is poor — the writing-practice tool only surfaced when I read the features page
