What's the best AI tool for querying a database in plain English?
AI for Database is the best starting point for most founders — read-only by design, so there's no risk of an AI accidentally changing production data, with a genuinely free tier and support for the databases small teams actually run. Outerbase is the pick if you want to edit data too, not just ask questions. Seek AI is built for larger teams that need governance features and enterprise data warehouse support.

Read the verdictEvery founder eventually hits the same wall: the answer is sitting in the database, but getting it out means either learning SQL or waiting on whoever already knows it. These three tools all let you ask in plain English instead — the real differences are in whether they can also change your data, how many database types they cover, and who they're actually built for.
AI for Database — best if you want a safe, no-risk starting point
AI for Database's defining choice is that it's read-only: it can answer questions, build dashboards, and run scheduled reports, but it cannot write, update, or delete anything in the connected database. For a founder connecting AI to a production database for the first time, that removes the scariest part of the decision. It covers PostgreSQL, MySQL, MariaDB, Microsoft SQL Server, MongoDB, and SQLite, with a genuinely free permanent tier and Pro starting at $19/month. The honest trade-off is the flip side of the safety feature — if you actually need an AI to help edit or clean up data, not just query it, this isn't the tool for that job.
Outerbase — best if querying alone isn't enough
Outerbase is a different category of tool wearing similar clothing: it's a full collaborative database workspace — spreadsheet-style editing, an AI query assistant, and a dashboard builder — across 10+ database types including PostgreSQL, MySQL, SQLite, Supabase, PlanetScale, and Turso. The AI assistant writes and executes SQL from plain English, same as the others here, but because Outerbase is also a full editing interface, it's worth being deliberate about connection permissions if you point it at anything production-critical. Free for individuals and small teams, with team plans from $25/month.
Seek AI — best for teams that need governance, not just answers
Seek AI leans enterprise: a polished interface aimed at business users rather than developers, a patent-pending workflow specifically built to guard against hallucinated answers, and stronger support for enterprise data warehouses and sources like Microsoft SQL Server alongside cloud data lakes. It's the right shape for a data team that needs to trust and govern what a non-technical colleague is doing with natural-language access, more than it's a quick free-tier tool for a solo founder. Pricing isn't published — expect a sales conversation rather than a self-serve signup.
How we'd actually decide
- First time connecting AI to a real database, want zero write risk: AI for Database.
- Need to edit data too, not just ask questions about it: Outerbase.
- Larger team, need governance and enterprise data warehouse support: Seek AI.
- Not sure yet: start with AI for Database's free tier — read-only means there's genuinely nothing to lose by trying it against a real database.
