It also offers several chat modes that change how the model behaves, such as research‑focused, code‑focused, or summarization‑oriented conversations.
How does ChatPDF handle privacy and data security?
ChatPDF processes your documents and questions in the cloud to generate responses, so files are uploaded to its servers rather than staying strictly local; the service states that it applies privacy and data‑handling measures, but users should avoid uploading highly sensitive or confidential content unless explicitly approved by their organization’s policies.
Is there a free plan and what does it include?
Yes, ChatPDF offers a free plan that typically allows a limited number of document analyses per day, such as around two documents, suitable for occasional personal use. The free plan still gives access to core features like chatting with documents, summaries, and basic Q&A, but with lower daily usage limits than the paid tier.
What is the Plus subscription and what extra features does it unlock?
ChatPDF Plus is a paid subscription that removes daily document limits and unlocks higher usage quotas, more advanced analysis tools, and access to priority or higher‑tier AI models. It is aimed at power users, teams, and professionals who need to analyze large libraries of documents, run complex data‑extraction workflows, or generate charts and reports at scale.
Can ChatPDF generate charts and reports from my files?
Yes, ChatPDF includes an AI Chart Pro feature that can generate charts from data in CSV, Excel, Google Sheets, and similar formats by running multiple AI models in parallel to produce visualizations. It also offers one‑click document and video analysis reports that summarize key points, entities, and insights from your files.
How do the knowledge graph and sandbox features work?
The knowledge‑graph feature maps relationships between entities, concepts, and documents so you can visually explore connections across your knowledge base. The sandbox and Sheets‑style sandbox let you run calculations, pivot data, and experiment with transformations in a safe environment without altering your original files, which is useful for financial modeling, research data, and spreadsheet‑like analysis.
