SocriFlow is an iPhone-first AI study app, not a generic chat tool. It starts from a source you will reopen (PDF, paper, notes), not a blank prompt. One source can continue into audio, flashcards, maps, and follow-up review after the first read. It fits second-pass study on iPhone. It does not replace NotebookLM's source-grounded notebook or ChatGPT's open-ended Q&A. Great for: • graduate students rereading papers on iPhone • students turning a PDF into flashcards and audio after the first read • anyone who needs the same source to stay usable after the first pass Use SocriFlow to: • upload a PDF, paper, or notes you will reopen • continue into audio, flashcards, maps, and follow-up review • keep second-pass study on iPhone Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ## Key features - AI-powered PDF analysis - Ask questions about documents - Generate concise notes - Create study flashcards - Listen to audio summaries - Supports various study materials ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Pro 专业会员 | $199.99 | per year | | Pro 专业会员 | $19.99 | per month | | Pro 专业会员 | $49.99 | per 3 months | | V5 Plus会员-月度 | $9.99 | per month | | V5 Plus会员-季度 | $24.99 | per 3 months | | V5 Plus会员-年度 | $99.99 | per year | **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Plus Monthly Subscription | $3.99 | one-time | | Plus Quarterly Subscription | $9.99 | one-time | | Plus Annual Subscription | $29.99 | one-time | | Pro Monthly Subscription | $6.99 | one-time | | Pro Quarterly Subscription | $19.99 | one-time | | Pro Annual Subscription | $49.99 | one-time | | 1st+20pts | $0.99 | one-time | | 20 points | $1.99 | one-time | | 80 points | $3.99 | one-time | | 200 points | $6.99 | one-time | ## Frequently asked questions about Socriflow ### What is Socriflow?
