## Napkin AI

Napkin AI takes a different approach to visualization: instead of prompting an image model, you bring your own words. Write, paste, or import text — from a doc, PDF, or notes — and Napkin analyzes the content to generate relevant diagrams, flowcharts, mind maps, infographics, and data charts. A single click on the Autospark icon produces visual options, and you choose the one that best expresses your idea.

Everything Napkin produces is editable. You can change colors, fonts, layouts, and icons, take a visual apart element by element, or swap it entirely. When your idea needs to become a deck rather than a single graphic, Napkin Slides collaborates with you before building, so the result feels like your own work rather than a generic template.

Finished visuals export as PPT, PNG, PDF, or SVG and drop straight into PowerPoint, Google Slides, Keynote, Notion, or a blog. Napkin supports 60+ languages and is aimed at professionals who need clear visuals quickly — project managers, teachers, consultants, marketers, and anyone who communicates complex ideas through slides and documents.

**Pricing & Plans:** Freemium. The free plan includes weekly AI credits, unlimited editing, unlimited file imports (PPT, DOC, PDF, HTML, MD), and unlimited PNG and PDF exports. Paid Plus and Pro plans unlock more AI credits plus PPT and SVG export, custom branding, and additional design options. Full details are on the Napkin pricing page.

- **Text-to-visual generation:** Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
- **Presentation decks:** Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
- **Fully editable output:** Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
- **Flexible export formats:** Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.

**Strengths:** No prompt engineering — it works directly from your existing text; Generates a wide range of visual types, from flowcharts to data charts; Everything stays editable and brand-matchable after generation; Free plan includes unlimited imports and PNG/PDF exports

**Limitations:** Free plan is credit-limited and some exports (PPT/SVG) and branding options sit behind paid tiers; Visual generation is not yet available on mobile; desktop is still the best experience; Generated visuals still usually need some manual styling to fully match a brand

## 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
