## pdfy.ai

pdfy.ai targets the everyday problem of too much material and too little time. Instead of scrolling through a 200-page script, a two-hour YouTube tutorial or a lengthy Wikipedia article, you drop the source in and start asking questions. The product handles four input families — PDFs, audio, websites and videos — and returns answers together with the passages they came from, which is what makes it usable for citing in academic or professional work.

The interface is deliberately minimal: a landing area to add sources, a chat surface for follow-ups, and a summary view. Limits are tied to your plan — the free tier allows a small number of sources and questions per month, while paid tiers raise both ceilings and unlock OCR so scanned documents can be read. File size is capped at 50 MB across plans, and support moves from self-service on the free tier to email on paid plans.

Because the tool is aimed at students, researchers and office workers, the emphasis is on understanding and quoting rather than bulk automation. Prompt suggestions cover summarizing, finding a specific fact, comparing sections and producing study-style notes. It is a focused utility rather than a full document-management suite, so teams that need shared workspaces may want to pair it with something else.

**Pricing & Plans:** Freemium. There is a free forever plan, a Premium tier around EUR 8.99/month billed monthly (list price shown as EUR 17.98 discounted), and an Ultimate tier around EUR 12.99/month (list EUR 25.98). Annual and half-year billing can cut the effective rate further. Paid plans raise source and question limits and include OCR.

- **Four source types in one chat:** Upload PDFs and audio, paste website URLs or YouTube links, and query all of them from the same conversational interface.
- **Answering with quotable passages:** Responses point back to the regions of the source they came from, so you can verify claims and reuse exact wording in your own writing.
- **Summarization and question limits by plan:** Free accounts get a handful of sources and questions each month, while paid tiers scale up to hundreds of sources and thousands of questions.
- **OCR for scanned documents:** Paid plans include optical character recognition so image-only PDFs and scans become searchable text instead of dead weight.
- **Audio, video and web comprehension:** Lecture recordings, meetings, tutorials and long articles are handled the same way as documents, making it useful beyond academic reading.

**Strengths:** Covers documents, audio, video and web pages in a single tool instead of four separate apps; Answers include the source passages, which makes verification and citation practical; Transparent, tiered limits that are easy to reason about before you commit; Free plan is usable for occasional light reading and testing

**Limitations:** Monthly source and question caps can be reached quickly by heavy users; Maximum file size is 50 MB on every plan, which rules out very large uploads; No free-tier email support, so troubleshooting relies on self-service

## SciSpace

SciSpace began as a typesetting and paper-formatting service called Typeset and has since grown into a broad AI research platform. Its core promise is that a researcher can move from finding a paper to understanding it to citing and writing about it without leaving one workspace. The platform indexes scholarly content from sources such as Google Scholar, PubMed and arXiv, and layers AI agents on top for reading, extracting data and synthesis.

The signature capability is conversational reading: you upload or open a PDF, then ask questions, highlight confusing sentences for plain-language explanation, or request structured summaries of methods, results and limitations. Around that sit task-specific tools — Literature Review, AI Writer, Paraphraser, Citation Generator, AI Detector, AI Humanizer, Extract Data and a Plagiarism Checker — plus a Chrome extension that adds the same assistant on top of publisher pages and a mobile app for reading on the go.

Access follows a freemium model: exploring and limited usage are free, while paid Premium, Advanced, Max and Enterprise plans raise model quality, credit limits and parallel agent capacity. The company is registered as PubGenius Inc. in Milpitas, California, and markets the product to individual researchers as well as universities and enterprises with SSO and admin controls.

**Pricing & Plans:** Freemium. A free tier with limited usage sits alongside paid Premium (~$12/month billed annually), Advanced (~$70/month) and Max (~$160/month) plans; monthly billing is higher. Enterprise pricing is custom. All plans advertise a 24-hour money-back guarantee, and annual billing carries a discount.

- **Chat with PDF:** Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
- **Literature Review and paper search:** Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
- **Writing, paraphrasing and citations:** An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
- **Extract Data and AI Detector:** Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
- **Chrome extension and mobile app:** Use the same assistant on top of publisher sites and PDF pages via the browser extension, or read and query papers from the mobile app.

**Strengths:** Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions; Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work; Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv; Free tier plus a Chrome extension make it easy to evaluate before paying

**Limitations:** Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans; Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models; AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity
