Every option in the catalog for when you need to ask a question in English and get correct SQL — 4 AI database and SQL copilots, 4 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 4 of them, ordered free tiers first: Chat2DB, Vanna AI, Wren AI and Outerbase. Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score.
2 on this page are marked fully free with no paid plan at all: Chat2DB and Vanna AI. The remaining 2 are freemium, trial or paid, and each is labelled with its exact tier so nothing surprises you at sign-up.
Free tools first, then freemium, then trial, then paid, and alphabetically inside each tier. Nobody pays to appear higher: Flocci AI Tools carries no ads, no sponsored slots and no paid listings, so the order reflects price and nothing else.
Chat2DB and Wren AI all work in a browser tab with no install needed — just open the site and go. 2 of the 4 free AI database and SQL copilots listed here are browser-based.
Chat2DB supports Google sign-in, so you can start without creating a new account. That's 1 of the 4 free AI database and SQL copilots on this page.
