Neon + CHION

Text-to-SQL for Neon PostgreSQL

Connect your Neon serverless PostgreSQL database to Chion and ask questions in plain English. Chion generates verified SQL, executes it read-only against your Neon branch, and renders interactive charts. All credentials are encrypted in vault — Neon's connection string is parsed into six fields on paste.

Example question & SQL

See what Chion generates from a plain-English question.

You ask

"Show me signup trends by week for the last 3 months"

Chion generates

SELECT
  date_trunc('week', created_at) AS week,
  COUNT(*) AS signups
FROM users
WHERE created_at >= now() - interval '3 months'
GROUP BY 1
ORDER BY 1;

Neon troubleshooting

Common issues and how to fix them.

Serverless cold-start delay

Neon computes scale to zero after inactivity. The first query after a cold start may take 1–3 seconds while the compute wakes up. Subsequent queries run at normal speed. To avoid cold starts, enable Neon's "Always on" compute setting.

Branch confusion — wrong data

Neon uses branches. Make sure you selected the correct branch in the Connect modal before copying credentials. Each branch has its own endpoint hostname.

Connection pooling toggle

In the Neon Connect modal, toggle "Connection pooling" on for pooled connections or off for direct. Chion works with both modes.

Your credentials are encrypted

All connection credentials are encrypted with AES-256-GCM and stored in an isolated vault. Chion connects with read-only permissions — no INSERT, UPDATE, or DELETE is ever possible. Row-level security policies are honored on every query.

Frequently asked questions

Common questions about using Chion with Neon.

Can I connect Chion to a Neon branch?

Yes. Each Neon branch has its own endpoint. Select the branch you want in the Connect modal and copy those credentials into Chion.

Does Chion work with Neon's free tier?

Yes. Chion's read-only queries are lightweight and work within Neon's free-tier compute and storage limits.

What is the default database name on Neon?

The default database is "neondb". You can verify this in the Connect modal's database dropdown.
