Rather than installing a heavy modeling suite with database access, it asks you to run one read-only query per DBMS — the project publishes a ready-made query for PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, ClickHouse, CockroachDB, Oracle, Snowflake, and BigQuery. Paste the output JSON and you get a full, interactive ER diagram that you can rearrange, annotate, and export. Beyond visualization, ChartDB works as an editor. You can add tables, subject areas, and sticky notes, edit relationships, use a DBML editor for text-driven modeling, and produce clean DDL scripts in your preferred SQL dialect. The AI ER diagram generator goes the other direction: describe what you want and get an editable, optimized schema draft. Diagrams are also exportable as images or embeddable previews for docs and wikis. The project is open source under AGPL and has accumulated tens of thousands of GitHub stars, which is why a self-hosted deployment is available alongside the Cloud product. Cloud plans add real-time collaborative editing, database auto-sync that keeps diagrams current as the schema changes, change logs and versioning, and an AI assistant. Teams get multi-user workspaces, 2FA, and priority support; larger organizations can request custom SSO and RBAC terms. **Pricing & Plans:** ChartDB offers a genuinely free open-source tier (self-hosted, AGPL) that includes all core features and up to two diagrams. Cloud plans run about US$25/month for a single user (Pro) and US$59/month for teams, with annual billing discounts of up to 40%. Custom enterprise pricing covers SAML SSO and granular permissions. - **One-query schema import:** Paste a single read-only query result and ChartDB renders the whole schema as an ER diagram, with no direct database access or local agent required. - **AI ER diagram generator:** Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL. - **DDL and diagram export:** Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation. - **Auto-sync and versioning:** On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift. - **Real-time collaboration:** Invite teammates to view and edit diagrams simultaneously, with multi-user workspaces and 2FA on team plans. **Strengths:** Truly open source with a generous free self-hosted option and no database access needed; Fast setup — a single query gets you a complete interactive diagram in seconds; Broad DBMS coverage including PostgreSQL, MySQL, SQL Server, SQLite, ClickHouse, Snowflake, BigQuery, and Oracle; AI generation works both ways: prompt-to-diagram and diagram-to-DDL **Limitations:** Cloud collaboration, auto-sync, and the AI assistant are paid; the free self-hosted tier limits you to two diagrams and ten tables each; Snowflake and BigQuery support sits on higher-tier plans; As a specialized ERD tool it does not replace a full data-governance or lineage platform [Profile (Markdown)](https://openaitools.app/tool/chartdb.md) ## Gauth Gauth is a study app that turns homework problems into teaching moments. A student photographs a question or pastes it into the web calculator, and the AI returns a structured solution that walks through the reasoning instead of just giving the final number. Coverage is deliberately broad: maths and calculus, statistics, physics, chemistry, biology, economics, literature, business, writing, social science and general-purpose subjects, which makes it useful across very different curricula rather than only for algebra drills. The platform pairs two layers of help. The AI layer answers quickly and free of charge for a limited number of questions, with detailed step-by-step explanations and tips on the concepts behind each step. On top of that sits a tutor service that connects students to real verified tutors around the clock; the company advertises tens of thousands of experts, high satisfaction rates, fast turnaround on hard problems and access to a large question knowledge base. Gauth also offers an Academy section with courses and a newer Gauth Atlas experience that turns subjects into explorable visual maps grounded in cited sources. Gauth is available on the web and as a mobile app on both iOS and Android, where it has a large review base. It follows a freemium model: a free tier covers everyday questions, while Gauth AI Pro unlocks unlimited answers and premium features via a free trial followed by a paid subscription. Exact plan prices and trial conditions should be confirmed on the official site. **Pricing & Plans:** Freemium. A free tier answers a limited number of questions, and Gauth AI Pro offers unlimited answers and premium features, typically starting with a free trial before a paid subscription. Check the official site for current prices and trial terms. - **Photo-based question solving:** Upload or paste a homework question and receive an answer in seconds, covering maths, sciences, business, writing and social sciences. - **Step-by-step explanations:** Solutions break the problem into clear steps with reasoning and conceptual tips, so students learn the method rather than only the result. - **24/7 human tutor service:** When AI output is not enough, students can escalate to verified human tutors for personalised guidance, including help with advanced problems. - **Gauth Atlas visual learning:** An explorable visual map turns a subject into zoomable layers of related ideas, with each image traced back to a real source. - **Cross-platform access:** Use Gauth in the browser or through the iOS and Android apps, with an Academy area for structured courses and a large study-resource library. **Strengths:** Works across a very wide range of subjects, not just mathematics; Step-by-step explanations focus on understanding rather than answer copying; Human tutors are available around the clock for problems the AI cannot resolve; Free tier plus mobile apps on iOS and Android make it easy to try **Limitations:** Unlimited answers and premium features require the paid Gauth AI Pro subscription; AI-generated solutions can still contain mistakes on unusual or ambiguous problems, so they should be checked; Reliance on instant answers can undermine learning if used without attempting the problem first [Profile (Markdown)](https://openaitools.app/tool/gauthmath-com.md) ## Frequently Asked Questions ### How do ChartDB and Gauth compare in monthly traffic?
