Study Junkie

Study Junkie is an AI tutor designed for lifelong learners. It enables users to convert any textbook, PDF, DOCX, or text document into a structured interactive course built around consuming the material, discussing it, and practicing until concepts are understood.

The process begins with uploading a document, after which the platform organizes the content into chapters. Users can read the material or listen to AI-generated audio narration with adjustable playback speed, allowing study at their own pace without fixed schedules. A chat interface provides access to an AI tutor that remains grounded in the uploaded source, answering questions, offering clarifications, exploring edge cases, and expanding on topics by adding text to the lecture when appropriate. Each chapter includes generated practice assignments such as comprehension questions, application tasks, and reflection prompts. Submitted answers receive immediate AI feedback to reinforce learning.

The tool preserves the full content of source materials rather than summarizing or shortening them. It supports eight languages: English, Russian, Spanish, French, German, Italian, Portuguese, and Polish. Users may upload material in one language and generate lectures and assignments in another. It is built for self-learners, autodidacts, and lifelong learners who study out of curiosity and passion for topics ranging from philosophy and history to business or technical subjects, without deadlines or grades.

Study Junkie is delivered as a web-based service. It offers two payment modes. The free forever self-service mode requires users to supply their own API key from supported providers Google Gemini, Anthropic Claude, or OpenAI, with many providers offering free-tier usage. The prepaid tokens mode allows pay-as-you-go top-ups with no API key required. Both modes provide unlimited courses, AI discussions, audio narration, practice assignments, support for the eight languages, and access to all future features.
