Ryuk
postgres · mysql · your warehouse

your database,
in plain english.

connect a database, ask a question. ryuk reads your schema, writes the SQL, runs it, and shows its work — so you can verify and move on. no copy-pasting schemas into chatgpt.

SELECT revenue, region, quarter
FROM sales_metrics
WHERE year = 2026
GROUP BY region

the unsexy parts, already built

six things you don't have to build yourself.

bring your own database

paste a postgres, mysql, or warehouse connection string. read-only by default. credentials encrypted, never logged.

it learns your schema

tables, columns, types, and relationships indexed on connect. ryuk knows which user_id joins where before you ask.

ask in english

plain questions. ryuk drafts the SQL against your actual schema, validates it, and runs it. no prompt engineering.

shows its work

every answer comes with the SQL and the reasoning that produced it. accept, tweak, or copy it out to your own editor.

pin what matters

save a query as a metric. arrange metrics into dashboards that refresh on load. no chart library to learn.

reports, not screenshots

turn any conversation or dashboard into a clean PDF. share it without a login — or stop sending screenshots in slack.

why not just chatgpt

it knows your schema. chatgpt doesn't.

ryuk reads your actual tables before answering. the SQL references columns that exist, joins that are correct, and types that match. every conversation is saved — revisit the query, export the PDF, or share the result without pasting screenshots in slack.

show me Q4 revenue by region, compared to last year
reasoning

joining sales_metrics on region and quarter. filtering for Q4 2025 and Q4 2024. aggregating revenue with YoY delta.

real questions

things worth knowing before you paste a connection string.

can i actually point this at production?

yes, but connections are read-only by default. ryuk can't write, update, or drop unless you explicitly flip that off — and most people never do. if you're still nervous, point it at a read replica.

what happens when the generated SQL is wrong?

you see every query before it runs. reject it, edit it inline, or accept it. ryuk also validates its own output against your indexed schema before execution, so hallucinated columns and bad joins get caught before they hit your db.

how are my database credentials stored?

encrypted before they hit disk. never written to logs. never sent to the LLM in a prompt — only table and column names are. the credential itself stays on our infrastructure.

which databases actually work?

postgres and mysql are first-class. bigquery, snowflake, and redshift work through their standard drivers. mongo, dynamodb, and other non-SQL stores aren't supported and probably won't be — ryuk is built around SQL.

is my data used to train models?

no. queries go to the configured LLM provider (anthropic or openai) under their standard API terms. no training opt-in happens on our side, and result data never leaves the request/response cycle.

what if i stop paying?

everything stays. you drop to the free tier, keep your connections, metrics, and reports, and just get fewer credits per month. no lock-in, no export fee, no deletion threats.
