FAQ from Periplus
What makes Periplus different from other AI learning tools?
Unlike static quiz apps or generic summarizers, Periplus treats learning as a continuous, evolving process. Its AI doesn’t just answer—it scaffolds, connects, and adapts. Every course, document, and flashcard is generated *in context*, informed by your prior interactions, knowledge gaps, and emerging interests—making learning deeply personal and intellectually resonant.
How does Periplus ensure I actually retain what I study?
Periplus embeds evidence-based cognitive science into its core: flashcards are auto-generated from *your* learning content and scheduled using algorithmic spaced repetition that adjusts based on your recall confidence and timing. Paired with low-stakes quizzes and concept-linking exercises, this transforms fleeting understanding into durable, transferable knowledge.
Is there a free tier available?
Yes—the Basic plan is completely free. You’ll have full access to AI course generation, document creation, flashcard review, and your personal library—with limits on monthly document volume (10), PDF uploads (not included), and advanced chat features.
What’s included in Premium—and why upgrade?
Premium ($14/month or $168/year) unlocks the full potential of Periplus: upload and learn from unlimited PDFs, interact with documents via conversational AI, store up to 1,000+ learning assets per month, generate image-augmented flashcards, and enjoy priority support and early feature access.
Can Periplus help me learn from my own research papers or textbooks?
Absolutely—this is where Premium shines. Upload PDFs (academic papers, lecture notes, manuals), and Periplus will extract key concepts, generate summaries, build custom flashcards, and let you interrogate the content through natural-language chat—all while preserving citations and technical nuance.
