## Mathpix

Mathpix combines a highly accurate OCR engine with a document conversion pipeline tuned for scientific and technical content. Snap a screenshot of an equation, a page of a textbook or a chemical structure diagram, and Mathpix returns editable LaTeX, Markdown, MathML, SMILES or ChemDraw — including tables, which most general OCR tools handle poorly. The company reports more than 5 million users, 3,000+ organisations and tens of billions of converted PDF pages.

The product line spans several audiences. Researchers and students use Snip, a snip-and-convert desktop app on macOS, Windows and Linux plus a Chrome extension, alongside a Markdown editing environment designed for collaborative scientific writing. Developers reach the same engine through the OCR API and Files API, billing per page or per request and embedding conversion directly into their own applications.

For large-scale work, Mathpix offers a Private Cloud OCR deployment and a Secure Conversion Service that processes whole PDF and image libraries on dedicated capacity — the pitch being millions of pages per hour instead of months of manual work. Pricing is freemium: Snip and the APIs have free tiers with usage limits, with paid individual, team and enterprise plans on top.

**Pricing & Plans:** Freemium. Free tiers exist for Snip and the APIs with usage limits; paid individual and team subscriptions plus contact-for-quote enterprise, Private Cloud OCR and Secure Conversion Service options.

- **Scientific OCR:** Recognises printed and handwritten math, chemistry diagrams, tables and text across many languages and returns editable output such as LaTeX, Markdown, MathML, SMILES or ChemDraw.
- **Snip desktop app and Chrome extension:** Screenshot any region of your screen or a web page and copy the converted math, chemistry or text straight to your clipboard with a keyboard shortcut.
- **Developer APIs:** The OCR API and Files API let you embed the same conversion engine in your own product, with support for Python and CLI workflows and full PDF document processing.
- **PDF and image conversion:** Convert PDFs to LaTeX, Word, Excel, Markdown, HTML or Overleaf-ready output, and images to LaTeX, AsciiMath, CSV or other structured formats.
- **Enterprise-scale services:** Private Cloud OCR and a Secure Conversion Service handle large document libraries on dedicated capacity for model training, accessibility and archival projects.

**Strengths:** Exceptional accuracy on equations, chemistry notation and tables where generic OCR fails; Covers many output formats and multiple entry points: desktop app, browser extension, API and CLI; Free tiers make it easy to test on real documents before paying; Established, widely used tool with enterprise-grade hosted conversion services

**Limitations:** Heavy or bulk usage is metered, so costs rise quickly with volume; Advanced enterprise options such as Private Cloud OCR require a sales conversation and custom quote; Focused on STEM content; not the cheapest option if you only need plain text OCR

## PDF.ai

PDF.ai is an AI document assistant that turns static PDFs into something you can talk to. You upload a file, then ask questions in natural language and receive answers grounded in the document, with citations pointing back to the relevant passages so you can check the source. This makes it practical for long reports, research papers, contracts, manuals and any dense document where you need a specific fact rather than a full read-through.

Beyond Q&A, the platform handles common document chores. It can summarize long documents, extract specific fields or structured data, and help you locate details quickly across multiple files. Because answers include citations, it suits readers who need to verify what the AI says rather than trust it blindly.

For teams that build their own tools, PDF.ai also ships a developer API. The API can parse documents, extract structured data and split PDFs, letting you embed document understanding directly into your own applications and pipelines. The combination of a polished chat interface for end users and an API for developers makes PDF.ai useful both as a standalone reading assistant and as a building block for document-heavy products.

**Pricing & Plans:** PDF.ai uses a freemium model with a free trial. Free access is limited in how many documents and questions you can use each day, while paid subscriptions raise those limits and unlock heavier usage plus API access. Check the official pricing page for current tiers and rates.

- **Chat with PDFs, with citations:** Ask questions in plain language and get answers drawn from your document, with citations back to the source passages.
- **Summaries and instant answers:** Generate quick summaries and find specific answers in long reports, contracts and papers without reading every page.
- **Data extraction:** Pull structured data and fields out of documents to reuse in spreadsheets, apps or other automations.
- **Developer API for parsing and splitting:** Use the API to parse documents, extract data and split PDFs programmatically inside your own workflows.
- **Multi-question document workflow:** Ask follow-up questions to dig deeper into a document, or jump between multiple uploaded PDFs in one workspace.

**Strengths:** Chat with PDFs and get answers with source citations; Handles summarization, Q&A and data extraction in one tool; Developer API for parsing, extracting and splitting documents; Free tier and trial make it easy to evaluate

**Limitations:** Free usage is limited in the number of documents and questions per day; Heavier workflows and API usage require a paid subscription; Answer quality still depends on the clarity and formatting of the source PDF; Scanned or image-only PDFs may need good OCR to be understood accurately
