Sheetkiln

A spreadsheet editor with a built-in AI assistant. Auto-fill formulas, work offline, and keep your data private.

Excelkiln is a spreadsheet editor with a built-in AI assistant — no internet connection or extra installation required. Smart formula help works right out of the box.

KEY FEATURES

• Built-in AI formula assistant: ask in plain language and get formulas auto-filled into your selected cells
• Zero-install AI engine: the language model ships inside the app, so AI features work fully offline and keep your data private
• Import & export Excel (.xlsx) and CSV files
• Insert images directly into your spreadsheet
• Rich editing tools: bold/italic/underline, alignment, number formats, cell merging, row/column operations, and more
• Available in Traditional Chinese, Simplified Chinese, and English

WHO IT'S FOR Whether you're managing a budget, analyzing data, or building quick reports, Excelkiln is your on-the-go spreadsheet companion.

All AI processing happens entirely on your device — your spreadsheets are never uploaded to any external server.

DEVICE RECOMMENDATION For the best AI performance, we recommend iPhone 14 Pro or newer (or any device with 6GB+ RAM). Older devices can run the app but AI generation may be slower.
