Visus

Visus is a web platform for individuals and businesses that want a custom ChatGPT-style assistant trained on their own documents and knowledge base for document Q&A and knowledge retrieval.

Key capabilities include:

• Document training and organization: Upload content (or connect sources) so it can be analyzed and used for fast retrieval.
• Conversational Q&A: Ask questions in natural language, get instant answers, and use follow-up questions to refine context.
• Verified, source-limited responses: Delivers answers based entirely on trained materials and enforces access control so users only see what they are authorized to access.
• Configuration and integrations: Tune sensitivity and accuracy, and connect tools such as Google Drive, Confluence, Notion, Slack, Microsoft Teams, Discord, plus a Chrome Extension.

Pricing: Visus offers a free plan at $0 per member, while its paid plans include a Standard plan at $20 per month per member, a Business plan at $50 per month per member, and a custom-priced Enterprise plan that requires contacting sales

What makes it notable: It focuses on security and permission enforcement (TLS 1.2+ in transit, AES-256 at rest) while keeping answers constrained to the user’s training data, a practical fit for internal knowledge bases and customer-support style assistants.
