Use cases

What your AI can do with Neruva that it can't do alone.

Frontier LLMs are powerful, stateless, and forgetful. Neruva gives your agent a brain that persists, reasons, and replays. Here's what that unlocks in practice.

01 · Across sessions

Your agent picks up where it left off.

· The pain today

Today's Claude Code session knows nothing about yesterday's. Every new chat starts at zero. You re-paste context, re-explain the codebase, re-state decisions you already made.

· With Neruva

Neruva stores typed events — decisions, mistakes, tool calls, LLM turns — with auto-embedded semantic search. Next session, your agent recalls what it learned in milliseconds. Every project. Every repo. Forever.

100 recalls/day free, sub-100ms p95, no card required.
02 · Learning from mistakes

The same bug doesn't bite twice.

· The pain today

Your agent makes a mistake, you fix it, you move on. Three weeks later it makes the same mistake again. The lesson didn't stick because there was nowhere to put it.

· With Neruva

Auto-record every fix as a typed mistake event with context. When the agent hits a similar situation, it pulls the past failure mode and works around it. We call this CBR (case-based reasoning) — it's standard in industrial AI, brand new to coding agents.

99.1% retrieval accuracy on 10k stored episodes at 617µs/query.
03 · Cross-project knowledge

Your codebase conventions travel.

· The pain today

Every new repo is a cold start. The agent doesn't know your naming conventions, your testing style, your way of structuring services — even though you've taught it twenty times in other projects.

· With Neruva

Federated agent_recall sees across all namespaces (every project) in a single call. Your agent answers "how do we handle pagination?" with what your team actually does, pulled from real past decisions — not what's average on the public internet.

Unlimited namespaces, every tier. One call, every project.
04 · Causal reasoning

"What if I'd done it the other way?"

· The pain today

Frontier LLMs can paraphrase "if X had happened" but they can't actually compute the counterfactual differently. The answer to "what if we'd shipped without the migration?" is the same as "we shipped with the migration" — just reworded.

· With Neruva

Pearl's do-operator, native in the substrate. Observing and intervening on the same variable return arithmetically distinct answers. Your agent can reason about cause and effect, not just describe them.

0.49 vs 0.01 gap on causal probe — observation vs intervention.
05 · Theory of mind

Track what each teammate believes.

· The pain today

When a sub-agent (or a human collaborator) holds a wrong belief, your top-level agent has no way to represent that without confusing it with ground truth. Multi-agent systems devolve into one big context window.

· With Neruva

Nested belief encoding: Alice believes Bob believes Carol believes X. Each layer is independently queryable. Validated to depth 1000 — far past anything you'd actually use.

Bit-identical replay at every depth. Recursive self-reference supported.
06 · Customer-grade memory

Multi-tenant agent memory, per end-user.

· The pain today

You're building a product on top of an LLM and every user needs their own persistent memory. You're trying to glue together a vector DB, a session store, an auth layer, and a key-value cache — and it's brittle and slow.

· With Neruva

user_id auto-folds to tags=["user:<uid>"] at ingest, auto-ANDs at recall. One namespace, infinite end-users, isolated by tag. Federation rolls up to your agent in one call. Drop-in for B2B2C.

Startup tier: 10M records, 500K calls/day soft cap, $149/mo.
07 · Compliance + audit

Replay any session bit-for-bit.

· The pain today

The customer asks: "why did your AI tell my user that?" Your support team has no way to reconstruct what was in context. The transcript is gone, the embeddings have drifted, the model version has moved on.

· With Neruva

Every Neruva op is deterministic from a seed. The .neruva file is a complete brain snapshot. Replay produces bit-identical output. The audit story regulators want, the debug story your team needs.

Deterministic across 20 reruns. Export → re-import → identical recall.
08 · Rule induction

Learn a rule from three examples.

· The pain today

Your agent keeps formatting outputs wrong. You correct it three times. Twenty messages later it forgets and starts formatting wrong again. Few-shot prompting doesn't persist.

· With Neruva

agent_induce_rule lifts a named transformation rule from a few demos. agent_persist_rule stores it durably. agent_recall_rule pulls it back next session. Survives 1000+ distractors at 100% recall.

Probe 34: 100% from 3 demonstrations across 28 synthetic ARC rules.

These aren't demos.
They're shipped, today.

Every capability above is exposed via the same MCP server, the same API key, the same billing. No research-paper download required — just npm install -g @neruva/mcp and you're live.
