Can I see a sample IELTS Writing report before signing up?

Yes. Open the sample reports on the landing page (Task 2 Band 5.5, Task 2 Band 7.5, Academic Task 1, or the flagship Task 1+2 report). They use the same examiner pipeline as a real Analyze. You also get one free demo check per network before creating an account.

How accurate is Stratum AI for IELTS scoring?

Our neural network is trained on thousands of official IELTS samples. Stratum AI achieves 98% correlation with human examiner scoring across all four criteria.

Does it support both Academic and General Training?

Yes. Use Academic mode for charts, graphs, and tables (Vision + overview/grouping strategy). Use GT Letter mode for General Training Task 1: tone (formal/semi-formal), every bullet point, salutation & closing, and a dedicated Letter Strategy panel after each check.

How does GT Letter checking work?

Choose GT Letter in Task 1, paste or generate a letter task with bullet points, set tone and purpose, then submit. The AI scores Task Achievement on bullet coverage and register — not chart language — and returns letter_strategy with per-bullet feedback and a full model letter rewrite.

Will using Stratum AI help me reach Band 8.0?

Absolutely. By identifying your recurring grammar strata and providing high-level lexical upgrades, Stratum focuses on the specific gaps preventing you from hitting Band 7.5+.

Is my data secure and private?

We prioritize your privacy. Your essays are processed via encrypted channels and are never shared with third parties or used for public model training.

Does STRATUM include a study plan and practice reminders?

Yes. Your Study plan page turns saved checks into a Writing profile: criterion averages, recurring error patterns, sub-topic trends, and curated links for weak areas. Optional email reminders in Settings let you pick local time, weekdays, and timezone so consistency becomes effortless.

Do I need an account to use STRATUM?

Yes. Create a free account to run essay checks, save history, and use your included credits. Sign in from the home page to open the writing lab.

Can tutors add personal feedback and share reports with students?

Yes. After AI analysis, use Tutor's notes below the essay for custom feedback. Adjust criterion scores manually if needed, then Save to Archive, Share a link, or download an Official PDF — tutor notes appear in the shared report and PDF.

NEURAL STRATA MAPPING

Draft · Original

“I think that technology is good for education. It helps students learn things faster and it is easy to find information on the internet. But some people say it is bad because students get lazy. Also, teachers don't need to talk much if there are computers. In the end, I believe technology is very helpful for everyone in schools.”

Band 5.5

Academic · Suggested Rewrite

“It is widely argued that the integration of digital technology has revolutionized the modern educational landscape. While critics maintain that an over-reliance on digital devices may induce intellectual passivity among learners, I assert that instantaneous access to vast information repositories significantly enhances research efficiency. Furthermore, pedagogical roles are evolving as educators transition from traditional lecturers to facilitators of digital literacy. Ultimately, when implemented strategically, technological tools serve as indispensable assets that foster an inclusive and dynamic learning environment.”
