Where PDF Guru Stumbles

Despite its strengths, PDF Guru can hit a few bumps:

Reliant on stable internet—offline work isn’t an option.
AI features are limited to simple summarisation.
No advanced AI chat for document queries.
Cloud storage options are basic.
Some tools sit behind paywalls, limiting the free tier.
