What is the Joshu Supabase connection?

You authorize your own Supabase account through Composio-managed OAuth. Joshu queries tables, counts rows, runs select statements, and reads database records. You work with an assistant who has a desk, a computer, and persistent memory, not a SQL editor you have to open just to check a customer status.

Is my Supabase data secure?

Yes. Every Joshu runs in its own isolated, sandboxed cloud computer. Database records Joshu reads stay in that private sandbox. Joshu only accesses the projects you authorize, and your data is never used to train public AI models.

Will Joshu write or delete data in Supabase without asking?

No. Every insert, update, delete, and schema change waits for your approval before it runs against Supabase. Joshu runs read queries and counts rows on its own to answer your questions.

What can Joshu access in Supabase?

The projects you authorize, including their tables, views, storage buckets, and project settings. Joshu can run queries, count records, and stage updates. Any change to data, schema, keys, or project settings waits for your approval.

What is the difference between Supabase SQL Studio and Joshu?

Supabase Studio requires writing manual SQL queries inside a dashboard tab. Joshu lets you ask questions in plain English, translates your intent into queries, and weaves live production numbers directly into your emails and investor updates.

Do I need a paid plan?

Joshu is $95 a month after a 14-day free trial. That includes your sandboxed cloud computer, a dedicated US phone number, an @joshu.me email address, persistent memory across your tools, and all tool connectors, including Supabase. There are no token fees. Paid data and media APIs from the tool catalog are extra, paid per call from a prepaid usage wallet.

What Joshu does

Joshu executes read queries across authorized Supabase tables, calculates customer metrics, and pulls specific record details when you research user issues. When drafting growth updates or checking payment states, it queries live data to ensure your numbers reflect reality.

What you do

Connect your Supabase account with OAuth and choose which projects Joshu may use. Joshu asks you to approve each data change or correction before it runs against live tables.

Why it sticks

Founders and operators frequently need basic numbers from their database, but writing SQL or asking developers creates bottlenecks. Joshu answers questions from your live tables in seconds.

Permissions and limits

Joshu works with the permissions of the Supabase account you authorize. Some actions use the project's service role and bypass Row Level Security. Joshu cannot write, delete, or change schema without explicit confirmation. You can revoke access anytime by disconnecting Supabase.
