Everything that turns practice into progress.
Keystral combines structured practice with the tools learners need to understand, remember and prepare.
Personalised daily plans
Each session focuses on the topics and level most useful to the learner.
Diagnostics and full mock exams
Identify the starting point, monitor improvement and practise under realistic conditions.
Spaced repetition
Important topics return before earlier learning is forgotten.
Spelling and word lists
English word lists for Years 3 to 11, French and Spanish GCSE vocabulary, key science facts, and times tables.
Instant feedback and helpful hints
Learners understand mistakes and receive guidance without simply being given the answer.
Feedback on writing
Longer answers get AI-generated feedback, checked against exam board assessment criteria, rather than being left unmarked.
Parent progress dashboard
See progress by subject and topic without having to supervise every session.
A clear next step every day.
Keystral uses what your child knows now to decide what they should practise next.
Establish the starting point
A diagnostic and each subsequent answer build a topic-by-topic picture of what your child understands.
Adapt the daily practice
Secure topics become more challenging. Gaps receive additional support and return at the right time.
Show progress clearly
Children see what to work on next. Parents see mastery, strengths and topics that need more attention.
One account for the years ahead.
A child can join in Year 3, Year 7 or Year 11. Keystral starts from their current stage and keeps their learning progress in one place as they move forward.
More than one child?
The Family plan gives up to three children their own profiles, progress records and personalised learning paths under one parent account. One child might be developing 11+ skills while another is revising for GCSEs. Their plans and results remain separate.
