Good to know

Before you choose.

Are these subscriptions?

No. FairPDF is $10, FairPDF+ is $20, F-cubed BYOK is $12, and FairPhoto is $29.99. All prices are in USD for a one-time app purchase. F-cubed's cloud provider charges are separate.

Which PDF app keeps AI on my Mac?

FairPDF+ runs its AI locally on Apple silicon. FairPDF is a local editor without AI. F-cubed BYOK uses your cloud API key and sends AI requests and relevant document content to that provider.

What does “local” mean here?

FairPDF+ processes your documents with models on your Mac. Downloads, update checks and checkout require internet access. FairPhoto includes its AI engine; image and video models need an initial download. Optional cloud services in FairPhoto send selected content to the chosen provider. Optional connected features in FairPDF and cloud AI in F-cubed use the network.

Will every AI-filled field be correct?

No AI tool can promise that. Review names, dates, numbers, checkboxes and field placement before saving or sharing a completed form, especially on scans and flattened PDFs.

What hardware do I need?

FairPDF and F-cubed require macOS 13 or later. FairPDF+ 1.1 requires macOS 26.2 or later and Apple silicon; 32 GB memory is recommended. FairPhoto’s editor runs on macOS 13 or later. Its included AI engine requires Apple silicon and macOS 14 or later; MLX models require macOS 26.2 or later. Larger AI models need more memory and disk space.
