Local models process PDF text on your Mac. You can ask questions and request summaries without using your AI allowance.
Download a Qwen model in Settings. JemPDF shows models that fit your Mac’s memory. Once prepared, ask questions and get summaries with citations offline, without an account.
Use Apple’s on-device model on a compatible Mac with macOS 26 or later and Apple Intelligence enabled. Optional offline fallback can use a prepared local model when the internet is unavailable.
Choose how much reasoning Jemy uses for each chat and model. GPT-6 in Cloud offers levels up to High; compatible Qwen models let you turn thinking on or off.
Reading and annotating PDFs is free. Cloud-based Jemy includes a free initial allowance. JemPDF Plus renews the allowances at a reference price of US$3 per month. Local text models work without a subscription.

JemPDF is a native Mac app for Apple Silicon and Intel. It requires macOS 14 or later.
You can add text, notes, highlights, underlines, strokes and shapes, organize pages and save changes. Editing uses annotations: this version does not modify the PDF’s original text or images and does not include OCR or permanent redaction.
Local reading, editing and local-model text questions work without an account. Cloud text, cloud dictation and Live conversation need a JemNotebook account, internet and their respective available allowances.
Download a compatible Qwen model or prepare Apple Intelligence before going offline. Select it in Jemy, or enable optional offline fallback in Settings. Local PDF text questions and summaries work without an account or AI allowance. Jemy stays on the local model after reconnection until you choose Cloud.
GPT-6 in Cloud lets you choose no reasoning, Low, Medium or High. Compatible Qwen models offer thinking on/off. The choice is remembered for each chat and model. More Cloud reasoning may use more AI allowance; local reasoning does not use it.
Local models process Jemy text on your Mac. Sending with Cloud shares the sources and relevant conversation context needed to answer, including local turns in a mixed chat. Local dictation keeps audio on your Mac; cloud voice uses its service. Cloud-library files keep their normal synchronization.
AI can make mistakes. Follow the citations back to the PDF and check the facts before using an answer.
