Connect it to your SQL database and it extracts the schema, categorical values, column relationships and comments automatically, so it can start answering questions for technical staff immediately with very little setup. Non-technical users can then ask questions in plain language and receive query results, charts and dashboards. A defining feature is its self-learning loop: BlazeSQL learns from user feedback on its answers and measures its own accuracy, which is what allows an organization to roll it out to business users with some confidence. There is a knowledge base for adding table and column descriptions, example queries and business terminology, so the AI understands company-specific language. Insights can also surface proactively through scheduled summaries and job-specific suggestions. The product comes in both cloud and desktop editions. With the desktop app, query results stay local on your machine and can run in offline mode; by default the AI only needs table and column names to generate queries. Outputs range from simple charts to PDF and interactive reports, and integrations let users query through tools such as ChatGPT and Claude connectors, Slack and Microsoft Teams. There are APIs for generating queries and for managing users and databases, enabling white-label or embedded deployments, and a limit of 300 tables per connected database. **Pricing & Plans:** Free trial available, with paid plans for teams and individuals plus custom pricing for enterprise, white-label and embedded use. - **Natural-language SQL generation:** Ask a question in plain language and BlazeSQL writes and runs the SQL against your connected database, no query syntax needed. - **Self-learning with accuracy tracking:** It learns from your team's feedback and measures its own accuracy, so you can safely open it up to non-technical users. - **Dashboards and reports:** Turn answers into drag-and-drop dashboards, shareable PDF reports and interactive reports that update on demand. - **Works where you work:** Query your data from Slack, Microsoft Teams, or via the Claude database connector and ChatGPT plugin. - **Privacy-first desktop mode:** Run the desktop app so query results remain local to your computer, with an offline mode for sensitive data. **Strengths:** No manual schema setup needed — it maps your database automatically; Built-in accuracy measurement and feedback learning make rollout to non-technical users safer; Desktop edition keeps query results local, with offline mode for sensitive data; Broad delivery options including Slack, Teams, ChatGPT, Claude and an embeddable API **Limitations:** Requires an existing SQL database, so it is not useful for spreadsheet-only teams; 300-table limit per connected database may restrict very large warehouses; Pricing for teams, white-label and embedding is quote-based rather than published [Profile (Markdown)](https://openaitools.app/tool/blazesql.md) ## Postgres Sandbox Postgres Sandbox, available at postgres.new, takes an idea that sounds unlikely and makes it work: a real PostgreSQL database running entirely inside your browser. It is built on PGlite, a full build of PostgreSQL compiled to WebAssembly, so there is nothing to install and no server to configure. The moment you start writing SQL, a new database is created for you automatically. Around that core it adds a set of tools for getting things done quickly. An AI assistant helps turn natural-language requests into SQL and to reason about queries, which is valuable when you are sketching a schema or exploring unfamiliar data. You can import CSV files and query them immediately, generate charts from results, and draw ER diagrams to see how tables relate. Because the engine is genuine Postgres, the SQL semantics match what you would get on a real server, which makes the sandbox a natural place to prototype schemas, test a tricky query, teach SQL, or experiment with semantic search and RAG-style retrieval. It is best understood as a fast, disposable workspace rather than persistent production infrastructure — data lives in the browser rather than on a managed database. **Pricing & Plans:** Free. Postgres Sandbox runs in the browser at no cost — there is no install, no account requirement mentioned and no paid tier advertised. Just open the page and a PostgreSQL database is created as you start writing SQL. - **Instant in-browser Postgres:** A new PostgreSQL database is created automatically in your browser via PGlite — no server, no installation, no configuration. - **AI SQL generation:** An AI assistant helps generate and reason about SQL from natural-language prompts, lowering the barrier for schema and query work. - **CSV import:** Load CSV data and start querying it directly, which makes the sandbox handy for quick analysis and data exploration. - **Charts and ER diagrams:** Turn query results into charts and draw ER diagrams to visualise table relationships within the same workspace. - **Semantic search and RAG:** Explore RAG and semantic-search style workflows against your data, using the sandbox to prototype AI data features. - **Real Postgres semantics:** Because it is real PostgreSQL, SQL you write here behaves like SQL you write on a server, so results transfer. **Strengths:** Runs real PostgreSQL with no install or server setup; AI assistance lowers the learning curve for SQL; CSV import, charts, ER diagrams and semantic search in one place; Genuinely free and instant to try in the browser **Limitations:** Data lives in the browser session, so it is not a persistent production database; Persistent storage depends on browser/IndexedDB and can be cleared; Not a substitute for a managed Postgres server for real applications; AI-generated SQL should still be reviewed before running [Profile (Markdown)](https://openaitools.app/tool/postgres-sandbox.md) ## Frequently Asked Questions ### How do BlazeSQL and Postgres Sandbox compare in monthly traffic?
