Better than a loose chat
Your learning does not vanish into a thread.
Benji keeps the curriculum, lesson history, completed sections, weak concepts, and review queue together so every answer has context.
The structure of a course. The patience of a tutor.
Benji turns any subject into a guided learning path, then adapts as you work through lessons, answer questions, get stuck, and improve. It is more organized than a chat thread and more responsive than a static online course.
- Track progress across sessions
- Practice with patient feedback
- Start free, no card
Benji lives between a course and a conversation.
A course gives structure. A chat gives flexibility. A tutor gives feedback. Benji combines the parts self-learners miss most.
More adaptive than a static course
The path changes when the learner changes.
Online courses move at one pace. Benji watches where you hesitate, what you miss, and what you master, then adjusts practice around your patterns.
Useful between tutoring sessions
Affordable, patient, and always ready to retry.
A great tutor is valuable. Benji is the cheaper everyday layer: no judgment, no clock pressure, and unlimited patience when you need the same idea explained again.
A learning loop built for follow-through.
-
1
Plan the path.
Type any topic and choose a level. Benji breaks it into sections with sensible order, time estimates, and editable goals.
-
2
Study with context.
Open a section for explanations, resources, practice, and Socratic questions that know what you are trying to learn.
-
3
Adapt and review.
Benji checks your answers, remembers weak spots, and sends missed concepts back into review instead of pretending one pass was enough.
Everything is organized around your next best step.
Structured paths
A real sequence, not scattered answers. Every topic gets sections, lessons, checkpoints, and visible progress.
Adaptive practice
Wrong answers become useful signals. Benji can turn mistakes into targeted remediation and review.
Socratic feedback
Answer probing questions and get feedback on your reasoning, not just whether the final line looks right.
Saved memory
Your paths, edits, lesson progress, weak concepts, and feedback stay available when you come back.
Curated resources
Books, articles, and videos are picked for the section you are on instead of dumped into a generic reading list.
Cheaper daily support
Use Benji for the repeated practice, explanation, and review work that is too expensive to outsource every day.
A generated path is only the beginning.
Benji starts with a course-like map, then turns each section into explanations, exercises, resources, and feedback loops.
-
01
Vectors and vector spaces
Vectors as arrows, as tuples, and as elements of an abstract space. Linear combinations, span, and the axioms that define a vector space.
≈ 1h 20m -
02
Linear independence and basis
When a set of vectors is independent, why a basis matters, and how dimension falls out of the definitions.
≈ 1h 30m -
03
Matrices and linear maps
Matrices as a way to write down a linear map between bases. Composition, identity, and the inverse when it exists.
≈ 2h -
04
Systems of linear equations
Row reduction, the geometry of solutions, and how the rank of a matrix tells you what to expect.
≈ 1h 40m -
05
Determinants and geometry
What a determinant actually measures, why it is multiplicative, and how it connects to invertibility.
≈ 1h 30m -
06
Eigenvalues and eigenvectors
The directions a linear map only stretches. Characteristic polynomial, eigenspaces, and why diagonalisation simplifies everything.
≈ 2h -
07
Inner products and orthogonality
Dot products, orthonormal bases, Gram–Schmidt, and the spectral theorem for symmetric matrices.
≈ 2h
Less than tutoring. More flexible than another course.

Questions, answered.
Still curious? Benji is happy to show you the rest inside the app.
What subjects can Benji teach me?
Anything you can describe in a sentence. Benji can turn physics, history, jazz harmony, a programming language, or a niche craft into a structured path with explanations, practice, resources, and checkpoints.
How is Benji different from just asking ChatGPT?
A chat is great for a quick answer, but it is easy to lose the thread. Benji keeps the path, progress, weak spots, lessons, practice, and feedback in one place so learning can continue across sessions instead of disappearing into a conversation history.
Do I need to pay to use Benji?
No. Free includes 120 starter credits plus 20 fresh credits every day for AI tutoring work. Reading saved lessons, editing curricula, and tracking progress stay free regardless of plan.
Is Benji a replacement for a human tutor?
Not for every learner or every situation. A great human tutor is still special. Benji is built for the everyday moments between tutoring or courses: it is much cheaper, available whenever you want to practice, patient with repeated mistakes, and focused on the patterns in your own work.
Is my learning data private?
Your saved curricula, edits, and Socratic answers are stored against your Google account on Benji's server and are only accessible to you. We do not sell your data or train public models on your conversations.
Can I edit a generated curriculum?
Yes. Every section is editable — rename it, rewrite the summary, or delete it entirely. You can also regenerate a single section if the first draft does not match what you wanted.
What age group is Benji designed for?
Benji is built for self-directed learners — typically high-school age and up — but it adapts to the level you choose (Beginner, Intermediate, Advanced) so the same subject can be paced very differently.
