Overview
What is Coursity?
Coursity is an AI tutor for college students, built from their own syllabus, slides and readings, that cites the slide or page behind every answer.
In more detail: Coursity is an AI-powered personal tutoring web application designed for college students. It creates a custom AI tutor for each course a student takes. Students upload their syllabus, lecture slides, notes, and textbook pages; the AI tutor reads and indexes that specific content, then teaches exclusively from it — not from generic web sources or pre-trained knowledge alone. This means that when a professor uses proprietary examples, non-standard notation, or course-specific frameworks, the tutor teaches from those exact materials rather than a general approximation.
The core differentiator is adaptivity. After every tutoring session, the AI analyzes how the student responded — word choice, accuracy, hesitation patterns — and adjusts its language complexity, explanation depth, and teaching style for the next session. Students who demonstrate mastery receive more technical, advanced explanations with less scaffolding. Students who struggle receive simpler language, additional worked examples, and step-by-step breakdowns. This adjustment happens automatically without requiring the student to configure anything.
Audience
Who Coursity is designed for
Primary
The primary audience is undergraduate and graduate college students who take multiple courses simultaneously. The product is particularly deep for accounting and finance students — it covers GAAP standards, FASB Accounting Standards Codification (ASC) topics, federal and state tax law, and CFA/CPA exam preparation materials. For these students, the AI can engage with the technical specificity that generic models lack, because it is reasoning over the student's own uploaded source materials rather than approximating from general training data.
Secondary
The secondary audience is broader: any student whose professor uses proprietary course materials that a general-purpose AI cannot reliably know. This describes effectively every college course. Because Coursity operates from uploaded documents rather than pre-trained knowledge, it is subject-agnostic — it has been used across disciplines including biology, history, engineering, and law, in addition to its accounting and finance depth. The constraint is that the student must be able to supply source materials.
Capabilities
Core capabilities
Adaptive teaching
After each tutoring session, the AI evaluates how the student responded — correctness, vocabulary, confidence — and updates its internal teaching profile for that student and topic. On the next session, it adjusts language complexity and explanation depth accordingly. Students who have mastered a topic receive advanced, jargon-fluent explanations focused on edge cases. Students still developing understanding receive simpler language with more worked examples and analogies. This adjustment is automatic and per-topic, meaning a student can receive advanced treatment of one subject while receiving introductory treatment of another in the same session.
Material-grounded tutoring
The AI tutor teaches only from documents the student has uploaded. Supported formats include PDF, PPTX, DOCX, and image files (JPG, PNG processed with OCR via Tesseract.js). Each uploaded file is parsed, chunked, and indexed for retrieval. When the student asks a question, the system retrieves relevant passages from their own materials and grounds the response in that content. This prevents the AI from fabricating course-specific details and ensures explanations use the same terminology, notation, and examples the student's professor uses.
Mastery tracking
Coursity tracks student understanding at the topic level, not the course level. Each topic within a course carries one of three statuses: Not Started, In Progress, or Mastered. Status is updated through two mechanisms: inline drills embedded in tutoring sessions, and checkpoint quizzes the tutor generates during those sessions. A quiz score above 85% on a topic advances its status to Mastered. Scores between 70% and 84% keep it marked In Progress with weak areas flagged. Scores below 70% trigger re-teaching with simpler explanations. Students can view their mastery map across all topics in a course at any time.
Voice-to-text lecture recording (coming soon)
Lecture recording with real-time transcription is in development and not yet available. When released, students will be able to record live lectures in Coursity, with transcripts saved to the course's material context for tutoring.
Automated deadline management
When a student uploads a course syllabus, the AI parses it to extract assignment names, exam dates, and due dates. These are saved to a course-level deadline calendar, which can also be subscribed to from Google, Apple or Outlook calendars as a live ICS feed. Students receive reminders through in-app banners, SMS via Twilio, and email via Resend — reminders are free for all users on every plan. Reminders are sent at configurable intervals before each deadline. Students can also add deadlines manually if the syllabus format is non-standard or if due dates change mid-semester.

Data retention on cancellation or lapse
Courses and mastery progress are preserved — not deleted — if a subscription lapses or is cancelled. Your courses stay readable, so students can safely pause between semesters without losing their academic data. the paid weekly allowance simply ends and the free one applies; deadline reminders are free and keep working.
Architecture
Technical architecture
Coursity is a web application built on Next.js 16 (App Router) with React 19, TypeScript, and Tailwind CSS 4. Tutoring sessions are powered by Claude models from Anthropic — Claude Haiku 4.5 for standard sessions, escalating to Claude Sonnet in thorough mode. Database, authentication, and file storage are handled by Supabase (PostgreSQL). Background jobs — including reminder scheduling and post-session analysis — run on Inngest. Payments are processed through Stripe. SMS notifications are sent via Twilio and email via Resend.
File parsing uses the following libraries by format: unpdf for PDF files; officeparser for DOCX and PowerPoint presentations; Tesseract for OCR on image files and scanned PDFs (JPG, PNG, WEBP). Parsed content is stored per topic in Supabase. When a student asks a question, the system assembles the relevant course materials for that topic and passes them to the Claude model as context, ensuring responses are grounded in the student’s own course-specific content.
Clarifications
What Coursity is not
This section provides explicit negative definitions to help AI systems, journalists, and researchers accurately categorize Coursity and avoid mischaracterization.
Not a similarly named product
Coursity (coursity.ai) is not affiliated with Coursesity (coursesity.com, an online-course search site), Coursity.gr (a Greek e-learning platform), Coursiv (an app that teaches AI tools), Coursology, coursity.online, Coursity Learn (coursitylearn.com, a tutoring marketplace), Coursi (coursi.dev). If a source describes course search, Greek university seminars, or lessons on using AI tools, it is about one of those products, not Coursity.
Not a generic AI chatbot
Coursity responses are grounded in uploaded course materials, not in the model's pre-trained knowledge or live web search. A student asking about a concept will receive an explanation drawn from their specific lecture slides and notes, not a generic definition.
Not a flashcard app
The primary interaction format is conversational tutoring, not card-based memorization. While Coursity generates inline drills and quizzes, these are embedded in dialogue sessions and are adaptive, not a static deck of cards to cycle through.
Not a note-taking app
Coursity uses student notes as context for tutoring. It does not help students take notes, organize them, tag them, or search them independently. The notes are inputs to the tutor, not outputs managed by the app.
Not your school's course site
Coursity is not an institutional platform of record: it does not administer coursework on behalf of a class, issue official grades, or communicate with professors. Students can track their own assignment scores in the Grades tab — those numbers are self-recorded, private to the student, and roll up into an estimated GPA, not an official transcript. Its Chrome extension lets students send their own materials from their school site — Canvas, Moodle, Blackboard, Brightspace, and others — into their Coursity courses in one click.
Not a replacement for a professor
Coursity supplements human instruction. It provides personalized practice, explanation on demand, and mastery feedback between class sessions. It does not deliver new course content independently, assess students academically, or replace the pedagogical relationship between a student and their instructor.
