Diffit vs Conker (2026)
Diffit
Freemium★ 4.4
Best for: differentiating reading materials for mixed-ability classrooms, adapting articles and texts for english language learners
Conker
Freemium★ 4.2
Best for: quick formative assessment and exit ticket creation, review quiz generation for unit tests and exams
Diffit vs Conker are two focused AI tools for teachers that solve adjacent but distinct problems. Diffit is a reading differentiation tool - it takes an article, document, or topic and generates multiple versions of the same content adapted to different reading levels, each with matching comprehension questions, vocabulary lists, and graphic organisers. The core use case is mixed-ability classrooms and ELL support, where producing separate levelled materials for different student groups traditionally takes hours. Conker is a quiz and formative assessment generator - it takes a topic, document, or learning objective and produces multiple choice, true/false, short answer, and open response questions that teachers can share with students via a direct link in seconds. The two tools are complementary rather than competitive. A teacher might use Diffit to create a differentiated reading activity on photosynthesis, then use Conker to generate a quick comprehension check at the end of the lesson. Where they overlap is in comprehension question generation from text materials - both can create questions from a given reading, but with different outputs and depth. Diffit's comprehension questions are levelled and tied to the adapted text, making them better for assessment within the differentiation workflow. Conker's questions are faster to generate, more varied in format, and better suited to standalone quiz deployment via link. For teachers who primarily need differentiated reading materials, Diffit is the clear choice. For teachers who primarily need quick formative assessment quizzes across any topic, Conker is the faster and more flexible tool.
Feature Comparison
Reading level differentiation
Diffit's primary function is generating multiple versions of the same content at different reading levels. Conker does not offer reading level adaptation - it generates questions at a single difficulty level.
Speed from prompt to deployable activity
Conker generates a shareable quiz from a topic or document in under a minute with a direct student link. Diffit generates comprehensive differentiated materials, which is faster than manual creation but produces more content and takes slightly longer to review.
Question type variety
Conker supports multiple choice, true/false, short answer, open response, and Bloom's Taxonomy targeting across question types. Diffit's comprehension questions are more narrowly focused on reading comprehension at the matched level.
ELL and multilingual support
Diffit generates content in multiple languages and at reduced complexity levels specifically for English language learners. Conker does not have dedicated ELL support features.
Google Classroom integration
Conker supports direct Google Classroom import for distributing quizzes as assignments within existing class structures. Diffit supports export and sharing but does not have direct Google Classroom push.
Supplementary material generation
Diffit generates vocabulary lists, graphic organisers, fill-in-the-blank activities, and discussion questions alongside the differentiated texts. Conker is focused on question generation and does not produce supplementary reading materials.
Free plan value
Both tools offer free tiers that cover most core use cases for individual teachers. Diffit's free plan covers levelled text generation with some creation limits. Conker's free plan covers quiz generation with limits on question count and advanced types.
Verdict
This comparison is context-dependent. Diffit scores 28/35 and Conker scores 24/35. Choose based on your specific workflow needs.
Bottom Line
Diffit and Conker both serve K-12 educators with AI but solve different problems. Diffit is the differentiation tool that adapts any text or video to multiple reading levels - useful for ESL, special education, and mixed-level classrooms. Conker is the AI question generator that creates differentiated quizzes, exit tickets, and assessments from any content. Pick Diffit if your bottleneck is adapting reading material for diverse learners. Pick Conker if your bottleneck is generating differentiated assessments at scale.
Pick Diffit
You are a K-12 teacher or instructional coach working with diverse learners (ESL, special education, mixed-grade classrooms) and the bottleneck is adapting reading materials. Diffit (free + paid tiers, often free for educators) generates differentiated text from any source.
Pick Conker
You are a K-12 teacher generating frequent quizzes, exit tickets, or assessments and want AI to produce differentiated questions at multiple difficulty levels from your content. Conker (free + paid) specialises in assessment generation.
Frequently asked
Which is more useful for ESL teachers?
Diffit clearly - the multi-level reading adaptation is the core ESL workflow. Conker can generate differentiated assessments to match but Diffit owns the input-side differentiation.
Are these free for teachers?
Both have generous free tiers for individual teachers. Premium tiers add features and remove limits but most classroom teachers stay on free tier.
Do they integrate with Google Classroom?
Both have Google Classroom and Canvas integration in 2026. Output flows directly into LMS assignments, reducing manual copy-paste work.
Best for special education?
Diffit for adapting reading materials. Pair with MagicSchool or SchoolAI for IEP narrative drafting. Conker for differentiated assessments. Most special-ed teachers use 2-3 tools across the workflow.
