A local AI co-pilot
built to act.

Delta is an on-device AI system that understands context, invokes tools, and executes real work across your machine. No dashboards. No noise. Just an agent that operates where you do.

Request access Local-first · Developer-controlled · Private by design

Not another chatbot.

Delta is architected as an agent, not a UI novelty. It maintains internal state, understands intent, and calls tools with precision. You don’t prompt it endlessly. You direct it.

Local execution

Runs on your machine or private infrastructure. No external dependency chains.

Tool-native

Functions are first-class. Delta reasons about actions, not text.

Private by default

Your data stays where your code lives.

Delta operates where failures actually happen.

Complex systems rarely fail loudly. Delta is built to notice the quiet inconsistencies engineers miss.

Incident analysis
Our API latency spikes only under load. Logs look clean. Can you figure out what’s going on?

Observation
worker_processes auto;
keepalive_timeout 5s;
The latency spike isn’t coming from application code. Under load, Nginx is aggressively closing keep-alive connections while your Node containers are CPU-throttled. This causes connection churn that only appears at scale.
Data integrity check
Revenue reports don’t match between our dashboard and Stripe exports.
execute_python()
Comparing timezone normalization
The discrepancy comes from invoices generated near midnight UTC. One pipeline truncates dates pre-conversion. The other does not. Totals diverge silently over time.

Listening
“Why did the deployment rollback even though tests passed?”
search_logs()
window: last 30m
The rollback was triggered by a health-check timeout, not test failures. The new build increased cold-start time by 800ms, exceeding your load balancer threshold.
Internal trace

tool.read_file → Dockerfile
agent.infer → connection churn under CPU throttle
agent.respond → root cause identified

Designed like infrastructure.

Delta is modular, inspectable, and deterministic where it matters. You can trace decisions, instrument behavior, and extend capabilities without fighting abstractions.

Agent core

State management, planning, and decision flow.

Tool layer

Declarative function metadata with runtime awareness.

Execution surface

OS, services, scripts, APIs, and automations.

Where Delta fits.

Developers

Code generation, refactors, system introspection, and workflow automation without cloud lock-in.

Founders & operators

Automate internal tooling, data movement, and operational tasks with full control.

Researchers

Experiment with agentic systems locally and reproducibly.

Security-sensitive teams

Keep proprietary data off third-party inference pipelines.

Build with an agent that respects engineers.

Delta is currently private. Reach out if you’re building something serious and want early access.
