No — complementary. Supabase hosts your Postgres and provides Auth/Realtime/Storage. AI2SQL is the AI layer that writes SQL for queries and migrations against that Postgres.
Yes. Copy the connection string from Supabase Settings → Database, paste into AI2SQL, and start generating queries. Works over SSL by default.
Supabase's AI assistant is improving but scoped to their platform. AI2SQL is a dedicated SQL generation tool with deeper schema context, multi-database support, and query optimization built in.
AI2SQL can generate CREATE POLICY statements and ALTER TABLE ... ENABLE ROW LEVEL SECURITY. For visual RLS management, Supabase Studio is still the better UI.
For query writing — yes, it's faster because of AI generation. For admin tasks tightly integrated with the Supabase dashboard (auth settings, storage, project config), keep using Supabase Studio.
