An interactive ER diagram with PK/FK icons and relationship lines — real constraints and the ones you only meant to add.
Every missing index, orphan table, and anti-pattern flagged with severity. Select what matters, let Gemini rewrite the DDL — then review the diff before anything lands.
ERD Factory separates FK relationships you actually defined from the ones your naming convention implies — so you can tell a guarantee from a guess at a glance.
Missing indexes on foreign keys, orphan tables, absent constraints — each detected automatically, ranked by severity, and queued for the same diff review as every other fix.
Skip the canvas when you just need answers: every table and column in full, filterable by any token. A naming-similarity inspector flags likely misspellings and duplicate names — the sloppy, inconsistent stuff convention-based matching alone can't catch.
Structural gaps and Gemini's own findings — normalization issues, anti-patterns, naming inconsistencies — land in one selectable checklist. Pick what to fix and Gemini rewrites the DDL to address just those, nothing else touched.
reviewed as a diff before it lands ↗Where AI Engineer patches what's broken, AI Designer builds what's missing. Describe a feature in plain language and Gemini proposes the tables, columns, and relationships to support it — revealed right on the canvas, highlighted alongside your existing schema instead of buried in a wall of SQL.
keep refining, or confirm when it's right ↗Organize schemas into Projects and Collections, mark one ready for review, and it shows up on your dashboard with a one-line summary of everything that's changed since it was created. Full version history means nothing gets lost between drafts.
