AI-Powered Knowledge Base
The ancient library,
reimagined.
Ask questions in plain language. Get answers sourced only from your organization's documents — never from general knowledge, never fabricated.
Capabilities
Everything your team needs to
unlock institutional knowledge
AI-Powered Q&A
Ask questions in plain language and get real-time streaming answers with cited sources. Every response is grounded in your documents through semantic search — never hallucinated.
Document Management
Upload PDF, DOCX, TXT, and Markdown files. Documents are automatically extracted, chunked, and embedded as vectors with real-time progress tracking.
Access Control & Roles
Four permission tiers from Super Admin to User. Control who sees what with category-based document access and secure invitation-based onboarding.
External Sources
Add external URLs as supplementary knowledge with automatic web scraping. Power users can toggle external sources on or off per query for precise control.
Simple by Design
Three steps to answers
Upload
Add your documents — PDFs, Word files, text, Markdown. Alexandria extracts, chunks, and indexes everything automatically.
Ask
Type your question in plain language. The AI semantically searches your entire document library to find the most relevant passages.
Get Answers
Receive precise, cited answers streamed in real time — grounded only in your content, never fabricated from general knowledge.
Enterprise-Grade
Security is not an afterthought
Every layer of Alexandria is built with security as a first-class concern.
Row-Level Security
Every database table is protected by RLS policies. Users only see what they're authorized to see.
Grounded Answers
AI responses are sourced exclusively from your documents. No hallucination from general knowledge — ever.
JWT Authentication
Secure token-based auth via Supabase with password strength enforcement and invitation-based onboarding.
CORS & Rate Limiting
Hardened edge functions with explicit origin allowlisting and rate limiting on every API endpoint.
Input Validation
Server-side validation on every input — message length limits, file size limits, and sanitized uploads.
Production Monitoring
Sentry error tracking catches issues before your users do. Continuous monitoring keeps the system healthy.
