BitSphere Private Document Chat 1.0
Private Document Chat helps you get clear, reliable answers from your own documents without reading them end-to-end or uploading them to public AI tools.
Requires .Net Desktop Runtime & Microsoft Visual C ++ redistributable to be installed.
Add your files and ask questions in plain English. The app reads and understands your documents locally and answers using only the information inside them. Your files never leave your computer.
There are no accounts, subscriptions, usage limits, or cloud services.
Private Document Chat is designed for people who need privacy, accuracy, and control over their documents. All processing happens on your own device.
Documents are processed locally. No data is uploaded or shared. No tracking or telemetry is used. An internet connection is not required.
The app works with Word documents, PDFs, and text files.
You can ask questions such as
- Summarise this document in bullet points
- What is the hybrid working policy?
- When do I need to provide a fit note?
- Explain this section in plain English
- What does this contract say about termination?
Answers are based only on the content of your documents.
Private Document Chat shows where answers come from so you can verify them. You can see which document was used, open the original file, and view highlighted sections that support each answer.
- The app is suitable for
- HR, legal, and compliance teams
- Consultants and professional services
- Professionals working with confidential files
- Students and researchers
Anyone who cannot upload documents to cloud-based AI tools
Private Document Chat runs AI models entirely on your own computer. Performance depends on your hardware and may be slower than cloud-based AI services, especially on older machines. This is the trade-off for full offline use and zero data sharing.
Designed for Windows desktop use.
