Frequently Asked Questions
Projectmem vs Voyage AI: which should you choose?
Choose Voyage AI if you need enterprise-grade embedding models for accurate retrieval over finance or legal documents and have budget to negotiate. Choose Projectmem if you're a developer wanting a free, privacy-first memory layer for AI coding agents like Claude Desktop or Cursor — it's perfect for personal or small-team use.
Can Projectmem replace Voyage AI?
No, they serve different purposes: Projectmem provides memory for coding agents, not retrieval embeddings or rerankers.
Does Voyage AI offer a free tier?
No, pricing requires contacting sales; there is no free tier or self-serve option.
Is Projectmem compatible with non-MCP agents?
It's designed for MCP-compatible tools; non-MCP agents may require custom integration.
Which tool offers better data privacy?
Projectmem, since it stores everything locally with no telemetry. Voyage AI supports SOC 2 and HIPAA but is cloud-based.
Can I use Voyage AI with any vector database?
Yes, Voyage's API integrates with any vector database or LLM.
Does Projectmem support multimodal memory?
No, it stores text-based context (issues, decisions, gotchas).
Which is better for legal document retrieval?
Voyage AI, with its domain-specific legal embeddings and rerankers.
Can I self-host Voyage AI?
Voyage AI is a cloud API; it does not offer self-hosting like Projectmem.
