The spreadsheet done right.

TukeySheets is the spreadsheet built for the way data works now. Publication-ready plotting, live connections to the warehouses and lakes where your data lives, and an application that humans and AI can both work in naturally — all at native speed on your machine. The spreadsheet is still the right interface for data. TukeySheets is the spreadsheet built for it.

Layered plotting
Pick a chart for the everyday work, or compose anything bespoke by layering plots. The same grammar is exposed to AI via MCP.
Bring your own AI
Built-in MCP server. Works with Claude Desktop, ChatGPT, Cursor, or anything that speaks MCP. Your data stays local.
Live data connections
Query CSV, Parquet, Postgres, Snowflake, and BigQuery with SQL. Schemas auto-discover. No extracts, no copies.
Native performance
GPU-rendered macOS app. Heavy data and complex plots stay responsive. No Electron, no browser tab.

Plotting

Pick a chart.
Compose anything.
Publication-ready.

Chart picker for the common cases: line, bar, scatter, histogram, candlestick, and more
Compose anything else: layer series, overlays, trendlines, error bands, and annotations on a single canvas
Same grammar drives the AI: agents read and write your plots through MCP, no screenshots required

AI Integration

Bring your own AI.
Keep your data local.

TukeySheets ships an MCP server that exposes your sheets, queries, and plots to whichever AI you already use — Claude Desktop, ChatGPT, Cursor, or anything else that speaks MCP.

No lock-in
Works with Claude Desktop, ChatGPT desktop, Cursor, or anything that speaks MCP.
Standard MCP
Tools and resources expose cells, ranges, formulas, and queries to your LLM.
Local-first
The MCP server runs on your machine, not in the cloud. Your spreadsheet stays on your machine.

Live Data

Your data stays live.
No copy-pasting.

Point TukeySheets at CSVs, Parquet, or external databases and write SQL across all of them. Schemas are auto-discovered, and a full language server delivers completion, hover docs, and inline errors for every backend.

SQL across CSV, Parquet, and external databases. One query language for all of them
Schemas auto-discovered, tables and columns appear the moment you connect
Full LSP per backend: autocomplete, hover docs, inline error squiggles
Spreadsheet formulas operate directly on query results

Native application

A native app.
Not a browser tab.

TukeySheets's UI stays fluid on datasets that bog down web and Electron apps. The reason: TukeySheets is a native desktop app that renders straight to your GPU, the same hardware that draws modern games, with no browser engine, no DOM, and no Chromium runtime in the way. Every scroll, redraw, and cell update goes directly to silicon built for exactly this.
