Master English without paying a dime! Keraft is built for non-member users, offering a fully free learning experience that combines smart technology, engaging interaction, and personalized support to make language progress accessible to everyone. Whether you’re a student, professional, or test-taker, Keraft turns English learning from a chore into a rewarding habit.

Free, All-Stage Learning Resources with No Barriers

Keraft breaks down paywall barriers by providing free access to a comprehensive library of vocabulary and learning materials, covering everything from primary school textbooks to advanced exam curricula like IELTS, TOEFL, and postgraduate entrance tests. It syncs with multiple mainstream textbook versions, so students can reinforce classroom knowledge without extra costs. Non-members can also build custom word lists via AI voice input, Excel bulk import, or photo recognition—perfect for specialized fields like medical or legal English.

According to an independent 6-week test by our review team (35 hours of use per app), Keraft’s free resources cover 80% of core learning needs for most users, enough to support progress from beginner to CEFR B2 (equivalent to IELTS 6.0).

Game-Learning Fusion: Make Practice Addictive

Tired of boring rote memorization? Keraft blends three game-based modes to keep learning fun:

  • Word Match: Match words to their definitions to clear blocks, with timed challenges to boost recall speed.
  • Word Sudoku: Fill in 9-grid puzzles with correct words to train vocabulary association skills, ideal for advanced learners.
  • Level-Up & PK: Work through progressive vocabulary levels, and join 3 free daily real-time PK matches with learners nationwide to stay motivated.

Every game session is powered by evidence-based spaced repetition, a method proven by classic psychology research to enhance long-term memory retention. The system adjusts review frequency based on your performance, ensuring tricky words are revisited at optimal intervals.

10-Minute Micro-Learning for Busy Schedules

Designed for people with fragmented time, Keraft makes daily practice effortless:

  • Grab a free 20-word basic task pack that takes just 10-15 minutes to complete.
  • Automatically save your progress to pick up where you left off during commutes, lunch breaks, or waiting in line.
  • Track your growth with a visual progress curve showing total words learned and mastery rate, so you can see your improvement clearly.

A working professional, for example, can finish one Word Match level on the morning commute, review mistakes during lunch, and join a PK match on the way home—accumulating 30+ new words daily without dedicated study time.

Smart Tools to Fix Common Learning Pain Points

Keraft offers free features to solve the biggest struggles of English learners:

  • Root Word Learning: Unlock 200 core root words for free, letting you master groups of related words at once (e.g., learning the root "happy" helps you remember "unhappy" and "happiness").
  • Photo-to-Word: Use AI image recognition to snap objects and generate bilingual flashcards with example sentences, making real-world vocabulary learning easy.
  • Intelligent Word Notebook: Automatically categorize incorrect words by mastery level, focusing review on what you actually need to practice. Words you answer correctly 3 times in a row are marked as mastered to avoid redundant practice.

Exclusive Keraft Advantages That Set It Apart

  • Phoneme-Level Pronunciation Correction: With 99.9%+ accuracy, Keraft corrects details like linking, weak forms, tongue twisters, stress, and pauses, targeting common Chinese accent issues.
