LightPDF

What is LightPDF?
LightPDF lets you upload PDFs, Word files, Excel spreadsheets, PowerPoint decks, and scanned documents, then ask questions and get cited answers back. The ChatPDF feature runs on GPT-4, supports multi-document chats, OCR for scanned files, and follow-up questions. You can upload a file up to 100 pages on the free web tier before upgrading.
Unlike standalone ChatPDF clones, LightPDF bundles document chat into a wider PDF toolkit with conversion, editing, e-signatures, and a dozen other AI tools like mind map creation, PDF translation, and presentation generation. One premium subscription covers Windows, Mac, Android, iOS, and the web app, with AI credits allocated monthly or as a one-time pool on the perpetual plan.
Researchers, students, and office workers use LightPDF to summarize contracts, extract tables from financial reports, and pull outlines from long readings. Business teams can also use it for document Q&A on proposals and compliance files. The company behind LightPDF has operated since 2015 and holds ISO/IEC 27001, ISO/IEC 27701, and GDPR certifications.
PDF Pals

What is PDF Pals?
PDF Pals lets you open any PDF on your Mac and ask questions about it in plain language, with answers tied to specific pages in the source file. The native macOS app indexes documents locally instead of uploading them to a cloud server, which makes it a fit for researchers, developers, legal teams, and product managers handling long technical or legal PDFs.
Most ChatPDF tools run in the browser and send your files to their servers for indexing. PDF Pals embeds documents on your machine with an open-source model, so a 2,000-page PDF costs nothing to process beyond your own API usage. You buy a perpetual license once ($60 to $300) instead of paying a monthly SaaS fee for document hosting.
You bring your own API key from OpenAI, Azure OpenAI, or OpenRouter, or point the app at a custom OpenAI-compatible endpoint. PDF Pals supports multi-document chats with no file size cap, OCR for scanned PDFs, and automatic redaction of emails, phone numbers, and credit card numbers before prompts leave your Mac.
The app is built by Podzim LLC, the team behind BoltAI and KTool. Files stay local, API keys sit in the Apple Keychain, training data lives in a local SQLite database, and the app ships without in-app analytics.
