ivySCI is dedicated to providing thoughtful and intelligent literature reading and management tools for researchers, helping them save valuable time and focus more effectively on their research, rather than getting bogged down in time-consuming literature management, especially the tedious task of formatting references for graduate theses. As your helpful assistant, ivySCI offers a comprehensive range of services from the outset, including: 1. After you import PDF documents, we automatically identify the metadata of each paper, including titles, authors, abstracts, DOIs, journals, and important journal impact factors (CiteScore). 2. For each document, we provide built-in translation and dictionary lookup to overcome language barriers. 3. We offer AI-assisted reading for each document, providing quick answers to your questions. In the Mac version, we also provide AI proofreading and translation functions. 4. We analyze each document so that you can access references directly when needed, without flipping to the end of the paper. After viewing the references, you can decide whether to download them. You can customize the download engine to provide more channels to help you find the required literature faster. 5. We extract images from papers and provide side-by-side text and image viewing when necessary. You can zoom in or out on images to focus on specific details. 6. We analyze the PDF structure and present it in an outline format. Thumbnails are also available for viewing. 7. You can create notes on any device, and these notes are shared via the cloud for easy access anytime, anywhere. 8. Your literature and notes are associated with your account, so you can use them on any device (including iPhone, iPad, and Mac) after logging in. 9. When writing in Word or WPS, you can cite literature and notes at any time using the ivyCite plugin provided by ivySCI. This ensures that your thought process remains uninterrupted. ivySCI offers various client options tailored to research needs, including Mac and PC, iPad, and iPhone. Each device serves a different purpose, with desktop versions offering comprehensive management capabilities, iPad versions focused on reading and basic operations, and iPhone versions providing basic information access. Depending on the intelligence analysis capabilities and the limitations of different PDF formats, some features may not be available, but we continuously optimize the engine.

Verdict
The clearest difference is ratings volume: Prodrafts at 3.8K against ivySCI's 9. Prodrafts also leads on update cadence (every 4 days vs fortnightly) and rating (4.8 vs 4.6). ivySCI's advantage is review sentiment (80% vs 70%) and iOS requirement (15.5 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Prodrafts sells 2 in-app purchases, starting at $6.99 per year and ivySCI sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Prodrafts holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Prodrafts has 3.8K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 70% of Prodrafts's written reviews are positive against 80% of ivySCI's, so the app with the better star average is not the one people write more warmly about.
Prodrafts ships an update every 4 days, ivySCI fortnightly. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
