We just shipped Vex v0.8.4 – the biggest connector update yet.

What’s new in v0.8.4

5 new connectors – Vex now supports 12 vector stores:

Connector Type Direction
redis Redis / Redis Stack VSS export + import
milvus Milvus / Zilliz Cloud export + import
neo4j Neo4j / Aura export + import
claude-export Claude conversation JSON export only
chatgpt-export ChatGPT conversation JSON export only

Plus the existing 7: vektor, jsonl, pinecone, qdrant, chroma, weaviate, pgvector.

CLI fixes:

  • All box-drawing characters and symbols now use \uXXXX escape sequences – no more mojibake on Windows Terminal
  • --help output shows all 12 connectors cleanly
  • Redis, Milvus, Neo4j options sections added to help

Bug fixes from v0.8.2/v0.8.3:

  • parseFlags loop fix (i=1 → i=0) – root cause of all key/flag failures
  • buildPrompt slice increased to 8000 chars
  • Token budget increased to 1400 for Groq/OpenAI branches
  • Graph builder SQLite CAST(strftime) datatype mismatch fixed
  • Embed auth failures now surface key status instead of silent failure

Install / upgrade

npm install -g @vektormemory/vex@0.8.4
vex --version  # should show v0.8.4
vex --help     # shows all 12 connectors

Migrate Claude conversation history into VEKTOR

One of the most useful new features – migrate your full Claude export directly into your VEKTOR memory graph with LLM fact extraction:

# Export your conversations from claude.ai -> Settings -> Export Data
vex migrate --from claude-export --to vektor \
  --file conversations.json \
  --db ~/.vektor/slipstream-memory.db \
  --mode smart \
  --openai-key $OPENAI_KEY \
  --namespace my-history

Migrate to Redis, Milvus, or Neo4j

# VEKTOR -> Redis Stack
vex migrate --from vektor --to redis --db memory.db --redis-url redis://localhost:6379

# VEKTOR -> Milvus / Zilliz Cloud
vex migrate --from vektor --to milvus --db memory.db --milvus-url localhost:19530

# VEKTOR -> Neo4j / Aura
vex migrate --from vektor --to neo4j --db memory.db --neo4j-url bolt://localhost:7687
