Could you build this?

Partial Enterprise AI search platforms like Glean require complex distributed connectors, permission-aware indexing, and a unified enterprise knowledge graph across dozens of SaaS APIs.

What it would actually take: A true open-source Glean alternative requires building a distributed multi-tenant ingestion engine with OAuth connectors for Slack, Google Drive, Jira, and GitHub, maintaining access-control lists (ACLs) per document in a graph database (e.g., Neo4j or HydraDB). The retrieval layer must perform real-time permission-filtered hybrid search combining BM25, dense vector indexing, and graph-traversal reranking before sending context to an LLM. This requires deep systems architecture expertise in data synchronization, rate-limiting queues, enterprise security boundaries, and search engine infrastructure.
