Chat with your Postgres databaseand trust the number

Ask your Postgres database a question in plain English and get a chart back with the verified, read-only SQL underneath it — Chion never improvises a query against your production data, it answers only from the SQL your team already trusts, and the whole skill set exports to Claude Code, Cursor, or Codex.

Stale dashboards. Disconnected AI. Blocked analysts. Chion closes the loop, from question to chart in seconds.

Chion compiles your team's verified queries into a portable skill library. Runs in Chion Studio or any LLM, with the same audit trail, the same row-level security, and every chart traceable to exact SQL.

Chion is your verified analytics team — finance, ops, growth agents, scoped by persona. From question to chart in seconds. Drop your agent + skills file into Claude Code, Codex, or Cursor — or chat with it inside Chion, where every answer routes to a verified query.

Close the loop — ask your database in plain English →

Your verified queries already exist.

One bulk-upload. Chion ships you a per-persona CHION.md agent. Domain-aware, table-scoped, ready for Claude Code, Codex, or Cursor.

No raw rows sent to the LLM.

The model only sees controlled summaries, counts, samples, and aggregations, not direct table access.

Read-only and encrypted by default.

SELECT-only credentials. AES-256 vault. Your data never moves.

Traceable SQL at every step.

Every answer shows the exact query that generated it.

Zero migration. Zero pipelines.

Connect to your database and query it where it lives.

Deploy on your terms.

Managed cloud today; dedicated infrastructure on the Enterprise roadmap. Same pipeline, same guarantees, wherever it runs.

Under the hood.

A multi-phase AI pipeline, not a wrapper around another LLM.

Read-only SELECT, row-capped, RLS-enforced — the LLM physically cannot mutate your data

We connect with the read-only role you give us. Your data stays in your database. We send schema metadata to the model, run the query, and render the chart. That's the entire data flow.

Encrypted credential vault

Credentials encrypted at rest. Decrypted in-memory only. Never logged.

Read-only by default

SELECT-only permissions. We will never modify or delete your data.

Row-level security honored

Your RLS policies are honored. Every query runs with your connection role's permissions.

Built by an analyst who got tired of waiting.

Founded in 2024 by Jonathan Dag, former Meta, Twilio, and American Express analyst.Read all

Jonathan Dag, Founder

After a decade building data infrastructure across Meta, Twilio, American Express, MasterCard, and Bosch, the pattern was always the same: analysts buried in SQL, business users waiting days for a dashboard update, and AI tools hallucinating the answer.

Chion is the analytics layer that should have existed from the start. Ask in plain English, get a verified answer backed by real, traceable SQL.

That's the tool I kept wanting someone else to build.

Choose how you deploy your portable SQL skills.

Quick Start

Connect PostgreSQL. Ask a question. Get a chart with the SQL behind it. Takes about two minutes.

  • Fast models for speed, advanced models for depth, selected dynamically
  • Search across your schema by meaning, not just column names
  • Connect your PostgreSQL database
  • Skip the ticket queue

Custom Setup

Pick your own model. Deploy on CoreWeave or your hardware. Same pipeline, same verification, just running where you control it.

  • PostgreSQL: the only language you need
  • Request your own model & infrastructure
    • Anthropic, OpenAI, Gemini, Mistral
    • On-prem or dedicated GPU options
    • CoreWeave cloud infrastructure

Agent Skills

Every verified query becomes a CHION.md skill: a portable SQL Analytics Agent file interchangeable with CLAUDE.md, AGENTS.md, and SKILL.md. Natively compatible with Claude Code and Codex.

  • One Markdown file, four idiomatic mirrors
  • Auto-promoted from your real queries
  • Per-domain, per-table, per-employee scoping
