Marking student writing is the task that quietly eats teachers alive — and the feedback often arrives too late to change anything. So a tool promising to diagnose writing gaps early and help teachers intervene sooner caught my attention. I looked closely at Tilf from the perspective of what actually helps in a classroom. Here’s my honest, first-person review.
Tilf is an AI-assisted writing assessment platform for schools. It runs weekly writing practice, reveals how writing develops across classes, and helps teachers diagnose gaps earlier, intervene sooner, and raise standards at scale. A school dashboard surfaces writing gaps by class so departments can see what’s working and expand it.
The class- and school-level view of how writing develops is built exactly for department-wide improvement.
AI-assisted assessment speeds up the diagnostic part, so more of your time goes to actual teaching and targeted intervention.
A dashboard showing writing gaps by class turns vague impressions into something departments can act on.
It’s designed around school/department workflows and dashboards, so a solo tutor may not need the full platform.
This assists teacher judgment; it isn’t meant to replace a teacher’s final assessment of a student’s work.
Regular, structured practice (the site cites +95% weekly practice) builds the habit and generates the data that makes diagnosis possible.
AI-assisted analysis flags writing weaknesses earlier — the site references roughly 3× earlier intervention.
See writing gaps by class across the school, so leaders can identify effective practice and scale it.
Feedback highlights where a student’s writing succeeds and where it falls short (e.g. not fully exploring imagery), guiding targeted teaching.
Tilf offers a free way to start and paid tiers, priced in British pounds. Based on the figures on the site at the time of writing:
Prices are shown in GBP (£) and can change — confirm the current tiers and what each covers (per teacher, class, or whole school) on Tilf’s site before purchasing.
Pros: early, data-driven diagnosis of writing gaps; drives consistent weekly practice; clear school/class dashboard; frees teacher time from marking; free tier to start.
Cons: built for schools/departments, not solo tutors; AI assessment should support (not replace) teacher judgment; GBP pricing and school-oriented tiers; value depends on consistent use across classes.
Generic AI graders score an essay and hand back a mark. Tilf’s edge is the longitudinal, school-wide picture — tracking how writing develops across classes over time and surfacing gaps early enough to act on. If you just want one essay scored, a generic tool works; if you want to raise writing standards across a department with data, Tilf is purpose-built for that.
For a school or English department serious about writing outcomes, Tilf makes a strong case — earlier diagnosis, consistent practice, and a dashboard that turns marking into insight. The value depends on genuine department-wide adoption, and it’s clearly aimed at schools rather than individuals. If that’s your context, the free tier is a low-risk way to trial it before rolling it out more widely.
Note on AI-assisted assessment: Tilf is designed to support teacher judgment, not replace it. Use AI feedback as a diagnostic aid, keep a teacher in the loop for final assessment, and follow your school’s data-protection and student-privacy policies.
Schools, English departments, and teachers who want to diagnose and improve student writing at scale.
No — it’s AI-assisted assessment that supports teachers, speeding diagnosis while keeping teacher judgment central.
