Introducing Kronvex: Persistent Memory for AI Agents — GDPR Native, Built in Europe

Your AI agents are amnesiac by design. Every session starts from zero. Kronvex fixes that — a persistent memory API that lets agents remember, recall and grow smarter over time. EU-hosted, GDPR compliant out of the box.

The problem: AI agents forget everything

You're building a sales assistant that learns your prospect's preferences. Or a support agent that remembers past tickets. Or a legal AI that recalls previous case context.

The LLM is stateless. The context window is finite. Every new session, your agent is a blank slate. You patch it with RAG, you store summaries in Redis, you hack together something that half-works — until it doesn't.

This is the memory problem in AI. And it's unsolved in the tools most teams reach for.

What Kronvex does

Kronvex is a dedicated memory layer for AI agents. Three operations, one API:

/remember — Store any piece of context. User preferences, conversation summaries, facts, decisions. Tagged with type (episodic, semantic, procedural), session ID, and optional TTL.
/recall — Semantic search over stored memories. Pass a query, get back the most relevant memories ranked by embedding similarity.
/inject-context — One-call convenience: recall + format as a ready-to-inject prompt block. Drop it directly before your LLM call.

from kronvex import Kronvex

client = Kronvex("kv-your-api-key")
agent = client.agent("agent-id")

# Store
agent.remember("User prefers formal tone", memory_type="semantic")

# Recall before LLM call
ctx = agent.inject_context(query="user preferences")
prompt = f"Context:\n{ctx.context}\n\nUser: {user_message}"

Why EU/GDPR matters here

🇪🇺 Data hosted in Europe · GDPR native · No config needed

Memory APIs handle sensitive data by definition. User preferences, conversation history, behavioral patterns — this is PII in most jurisdictions.

Every major memory API is US-hosted. For a European SaaS, using them means cross-border data transfers, SCCs, DPAs, and compliance overhead that kills velocity.

Kronvex stores all data in Supabase EU (Frankfurt). GDPR compliance isn't a checkbox — it's the default. No data leaves Europe, no additional configuration required.

For B2B SaaS, GDPR compliance is a sales argument. Your enterprise customers' DPOs will ask where memory data is stored. "Europe, encrypted at rest and in transit, no US transfers" closes that conversation in one sentence.

Built for B2B verticals

Generic memory APIs don't have a wedge. Kronvex does: we're building specifically for B2B AI agents in three verticals where persistent memory has measurable ROI:

CRM & Sales agents — remember lead preferences, past conversations, deal context across weeks of engagement
Customer support agents — recall ticket history, user profile, previous resolutions without re-querying your CRM every call
Legal & compliance agents — store case precedents, client context, regulatory interpretations with full auditability

If your AI agent talks to humans repeatedly, Kronvex gives it the memory to get better at it over time.

SDKs and integrations

We're shipping with Python and Node.js SDKs available today on PyPI and npm:

pip install kronvex    # Python ≥ 3.9
npm install kronvex   # Node ≥ 18

LangChain, CrewAI, n8n and LangGraph integrations are in progress — see the integration docs for the current patterns while we work on native plugins.
