Evidence-first document intelligence

Ask your documents. Check every answer.

Scribe turns private PDFs, DOCX files, notes, and datasets into a searchable knowledge workspace. Every response is grounded in retrieved passages and linked back to its source.

Engineering decisions

Designed for the failure modes a demo usually ignores.

Scribe is a portfolio project with production-minded boundaries. The codebase includes migrations, route validation, webhook verification, ingestion policies, retrieval evaluation, and focused tests.

Security

Tenant isolation at every boundary

Files, chats, vector search, usage, and billing are scoped by the authenticated Clerk user, not filtered later in the UI.

Reliability

Background ingestion that can recover

Atomic job claims, bounded retries, exponential backoff, idempotent callbacks, and stale-job recovery keep document processing reliable.

Observability

Evidence users can inspect

Answers link to retrieved passages. The RAG inspector exposes chunks, similarity, latency, and grounding signals without cluttering the default workflow.
