Tassomai vs CENTURY Tech: self-setting micro-learning vs curated digital nugget libraries

School leaders looking for digital learning platforms encounter a wide range of approaches to artificial intelligence and adaptive study. Tassomai, ranked fifth in TIME’s World’s Top EdTech Companies of 2026, is one of the best-known names among them.

In UK secondary education, CENTURY Tech is well known for its comprehensive, modular platform. Built around short learning units called nuggets, CENTURY offers a broad library of video clips, reading slides and diagnostic quizzes designed to help pupils work through curriculum pathways.

While CENTURY provides a detailed digital workspace with extensive analytical options for senior leaders, classroom implementation often reveals a key practical difference in how platforms manage teacher workload and student practice.

CENTURY offers a Recommended Pathway and Smart Assignments, but how much structured practice pupils get each day depends on how teachers set these up.

Tassomai takes a different approach by focusing on automated, self-setting micro-learning that runs without teacher intervention.

Comparing these two models helps headteachers and department heads evaluate how each platform manages teacher time, student engagement and daily study habits.

How a platform handles task assignment directly affects weekly teacher workload.

CENTURY offers an extensive range of digital nuggets across core subjects. Teachers can curate these units to build custom learning pathways or assign specific nuggets for homework. While this model gives staff granular control over the material assigned to a class, maintaining this process across multiple year groups requires regular planning, task selection and admin time.

Tassomai removes task setting from the teacher’s daily routine entirely.

The algorithm sets personalised Daily Goals automatically for every pupil based on their specification and accuracy history. Teachers don’t need to search content banks or schedule weekly tasks, though they can still set a Class Task for the whole class. Instead, the platform manages the entire curriculum behind the scenes, using spaced repetition to bring back topics just as memory starts to fade.

Where and how pupils access their homework influences completion rates across all year groups.

CENTURY is a web-based platform where pupils complete assigned nuggets by reading text slides, watching instructional videos and answering follow-up questions.

Tassomai prioritises low-stakes practice built specifically for mobile devices:

• Tassomai runs on a dedicated native app: pupils open the app on their phone or tablet and jump straight into their personalised Daily Goal without navigating complex browser menus.
• Micro-sessions respect student time: practice is broken into manageable sessions of 10 to 15 minutes that focus purely on active recall rather than long video streaming.
• A desktop app protects task validity: Tassomai’s desktop app for Windows, Mac and Linux blocks AI screen-reading extensions, so homework data reflects what pupils actually know.
• Mai provides immediate support: when a pupil makes an error, our built-in AI tutor steps in right away with clear, step-by-step guidance mapped directly to UK mark schemes.

Senior leaders need diagnostic tools that translate independent home practice into clear, actionable classroom feedback.

CENTURY’s data insights track completed nuggets, scores and time spent, helping teachers decide what to teach next.

Tassomai translates daily practice into visual classroom heatmaps:

Tassomai’s visual Understanding Grid gives department heads an instant, colour-coded map of topic accuracy across entire cohorts. Teachers can see at a glance if a class is struggling with a specific chemistry formula or maths concept, allowing them to adjust their next lesson without spending time analysing individual mark sheets.

Tassomai is built on retrieval practice and spaced repetition, two techniques with decades of cognitive science behind them. The platform’s own evidence matters too: in a study with UCL’s EDUCATE programme, struggling students answered over 70% of questions correctly straight after a Tassomai tutorial video, against 26% in a control group. That work earned Tassomai an Evidence Applied EdWARD from UCL’s EDUCATE programme.

In practice, this is what a Tassomai school gets:

• Pupils get a Daily Goal of 10 to 15 minutes they can finish anywhere, with Tassimals, streaks and the Achieviary to keep them coming back.
• Teachers get homework that sets and marks itself, and an Understanding Grid that shows which topic to reteach tomorrow.
• Parents get an email every Monday showing how many days their child was active, their accuracy and their weakest topic.
• Leaders get whole-school usage and Daily Goal completion by class and year group, without chasing staff for data.

If you want a library of lessons, with videos and reading slides that teach new content, CENTURY is built for that.

If you want every pupil doing focused retrieval practice every day, with no homework to set or mark, answers that are pupils’ own work and a live picture of what every class knows, Tassomai is built for that. It works alongside your teaching, keeping what pupils learn in lessons secure all the way to the exam.
