Bite-sized mastery for complex skills.
Sushimind is a modular learning platform in development. We are building a way to turn long, overwhelming courses into short lessons, each ending with an active recall check. We build Sushimind with Claude Code, and we plan to build features using Claude for lesson creation and learner feedback.
Why traditional online courses fail learners
Many online courses rely on long videos that learners watch passively. Completion rates for online courses are often low, and watching someone else do a task is not the same as practicing it.
Passive Video Fatigue
Long video courses can overwhelm learners. Watching can feel like learning, but much of it is forgotten days later.
Cognitive Load Theory
Working memory can only handle a few new elements at once. When a lesson overloads it, learning becomes harder and people are more likely to give up.
Modular Active Recall
We are designing Sushimind to package knowledge into short, self-contained lessons. Each lesson will ask for active recall before the next one opens.
Experience the Sushimind workflow
Try a sample lesson below. It shows how a lesson and its recall check are planned to work. All content and numbers are sample data, and no AI runs on this page.
Retrieval Practice vs. Passive Review
Reading highlighted summaries produces high subjective fluency but rapid forgetting. Remembering for the long term usually takes the effort of retrieving information without external cues.
Concrete adjustment: Select exactly one database query from your project today. Write down its three failure modes from memory. Do not touch the rest of the architecture until that single bite is validated.
Designed for comprehension, not video vanity metrics
Every planned feature in Sushimind has one purpose: making it easier to learn and to check what you have learned.
Modular "Sushi" Learning Units
Just like high-grade sushi presents concentrated flavor in a single bite, Sushimind is designed to break complex subjects into short, self-contained lessons. Each lesson is meant to take under 15 minutes.
Active Recall Checkpoints
Every lesson is planned to end with a recall question that checks understanding before the next lesson opens.
Planned: Claude Diagnostic Feedback
Claude will read learners' written answers, point out likely misconceptions, and suggest one concrete next step. We plan to build this feature.
Distraction-Free Minimalist UI
Designed according to editorial principles: pure typography, balanced whitespace, no advertisements and no algorithmic feeds, so learners can focus.
How we plan to use Claude (planned)
Today we build Sushimind with Claude Code. Inside the product, we plan to build two uses of Claude, shown below as planned steps.
Raw Knowledge Ingestion
Instructors will upload their existing material, such as documents, transcripts or course outlines. Claude will read the material as a whole.
Modular Synthesis
Claude will suggest how to split the material into short lessons and draft a recall question for each one. The instructor reviews and edits everything before learners see it.
Personalized Guidance
Learners will work through the short lessons. When they write an answer in their own words, Claude will give feedback on what they may have misunderstood and what to try next.
Rooted in cognitive science
Four research-based principles guide how we are designing Sushimind.
Spaced Retrieval
Reviews concepts at growing intervals to slow down forgetting.
Cognitive Slicing
Isolates one variable per lesson bite to keep working memory clear and focused.
Immediate Feedback
Aims to catch misunderstandings early, before they stick.
Practice over watching
Measures progress by challenges completed, not minutes of video watched.
What the research says
Sushimind is designed around three well-known findings from learning research. These are summaries in our own words, not quotes.
Testing yourself beats re-reading
In a well-known experiment, students who practiced recalling material remembered much more a week later than students who kept re-studying it.
Working memory is limited
People can only process a few new pieces of information at once, so lessons work better when they do not overload working memory.
Feedback should show the next step
Feedback helps most when it tells learners where they are, where they are going, and what to do next, rather than only praising or grading.
