Feedback:

With a single click, Olex.AI generates personalised feedback for every pupil in the class. Teachers stay in full control: they choose the framework, then review and edit before anything is shared.

EAL support:

Feedback is instantly translated into 100+ languages, so every student, and their family at home, can understand what they did well and what to work on next.

Whole-Class Feedback:

Clear insights into strengths and gaps across the whole class, so teachers can plan teaching with impact. Lesson plans are generated automatically from the class’s priority next steps.

Imaginator:

The Imaginator turns students’ writing into vivid, personalised illustrations, motivating reluctant writers and inspiring richer, more descriptive language.

Olex Script:

Get a complete picture of every student’s handwriting from the work they upload: feedback on legibility, reader effort, layout and letter formation, with clear next steps.

Consistent & data informed insights

Olex Analytics turns assessment into reliable, comparable data and produces moderation evidence in a single click. Powerful dashboards track progress and attainment over time.

Insights:

Track every school and class across your trust over time, or drill into strengths and gaps by assessment area to see exactly where CPD will make the biggest difference.

"We saw a 13% uplift in our English Literature results this year at grade 5. One reason was definitely the frequency we could produce and assess student submissions on Olex."

FAQs

Yes, Olex.Al is designed to significantly reduce teacher workload through rapid AI assessment. Teachers typically save between 60 and 90 minutes per week on marking and feedback as the platform can mark an entire class of 30 essays in minutes.
Students do not have to type, the platform is built to work with both handwritten and digital work. It works naturally with standard exercise books—no special paper or templates are required. Students, or teachers, can take a photo of handwritten work on a desktop, mobile or tablet. Or work can be scanned in bulk, using a flatbed or office scanner.
For Multi-Academy Trusts (MATs), Olex.Al provides a strategic, “examiner-level” solution to standardise writing assessment and moderation across all member schools. Trust leaders gain access to high-level dashboards that track student progress and attainment trends in real-time, allowing for data-driven interventions and the targeting of Professional Development (CPD) where it is most needed. To ensure a smooth rollout, every Trust is supported by a dedicated Trust Implementation Plan (TIP) and a Partnership Manager, ensuring that the technology is embedded consistently to reduce teacher workload and improve standards trust-wide.

Olex.Al is designed to be highly inclusive for EAL students by removing language barriers that often hinder writing progress. The platform features an automated translation module supporting over 100 languages, allowing feedback to be translated into a student’s native language to build confidence and involve parents in home learning. This multi-layered support ensures that pupils can access high-level writing tasks and receive rapid, detailed feedback regardless of their primary language, helping to accelerate their progress alongside their peers.

For SEND students, you can tailor feedback to each student’s language level, and students who find handwriting difficult can type their essays directly in the Olex.AI Student Portal. Teachers review every piece of feedback before it’s shared, so it always fits the individual student.

Olex.Al places the highest priority on data security, ensuring that all student information is managed within a strictly protected environment that is fully UK GDPR-compliant. Student work is never used outside of Olex to train any global AI models, ensuring all data remains private to the school. Furthermore, every piece of feedback and every image generated is subject to strict moderation, with no content reaching a student until the teacher has reviewed it and manually clicked “Send”.

You can read more about our approach to safe AI in schools here. 

We have implemented strict safeguarding protocols, including:

  • Content filters that prevent inappropriate language in feedback or generated outputs.
  • Restricted image generation with multiple layers of security to ensure that any images created (where applicable) are strictly appropriate for educational contexts.
  • Access controls to ensure only authorised staff and students can access the platform.
  • Our safeguarding measures are continuously reviewed and updated in line with national guidance for online safety in education.

Yes, but the key is separating formative and summative stages. During drafting and revision, teachers can use AI feedback tools (or their own teacher feedback) to support students. However, the final piece submitted for KS2 teacher assessment must be written independently by the student — no AI-generated feedback should be used to guide that final submission. Teachers are still welcome to upload the final piece to the analytics dashboard, as this is purely for teacher analysis and does not involve guiding the student.

Yes. Olex.AI marks 30 GCSE essays in minutes – handwritten or typed – with consistent, examiner-level feedback for every student. There are no per-script fees. Unlimited marking is included in your annual subscription, and class-level analytics show you exactly where marks are being lost so you can target intervention fast.

Yes. Olex.AI has been developed and refined with input from experienced teachers and examiners and is continually tested against the teacher and examiner’s own marking. Its judgments are transparent, consistent, objective, and aligned with national standards. Many schools use it as part of internal moderation processes to ensure fair and robust assessment.
