Formative
Pros
- + Live response view shows student work as it is created — in my use this is the strongest mid-lesson intervention workflow in the assessment category
- + Response breadth beats quiz tools: drawing/whiteboard, graphing, equations, image annotation, audio and video responses alongside 20+ item types
- + Real digitisation of old material — upload a PDF or Doc and add response fields to it instead of rebuilding
- + Pricing is concrete and moderate: $249/teacher/year with a genuinely usable Free Teacher plan and a 14-day trial without a credit card (formative.com/plans, at time of writing)
- + District depth is real: standards dashboards, common assessments, Item Bank, Respondus LockDown, and Luna Configuration Studio for district AI guardrails
Cons
- - Collaboration is gated — shared libraries, common assessments and org dashboards require the school tier or above; no family/caregiver access at all
- - AI scoring of complex open-ended work is uneven and needs teacher review (consistent with a 21-teacher AIME 2025 pilot); no plagiarism checking
- - Since February 5, 2026 new monthly subscriptions are gone — individuals must buy annual despite school-year-shaped need; plan names keep changing post-Newsela
- - Video embeds depend on YouTube, which many districts block; a long-running user complaint without a built-in video-hosting alternative
- - Item formats skew to right/wrong answers; richer demonstration of learning needs custom rubric work on top
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
