Fledgling · Plain-text tools for structured thought
Write it. Compute it. Show it.
Four tools for documents, data and decks. Plain-text native, engine-first, built from scratch. So humans and AIs can author together at full speed.
Typewright
MARKDOWN + MDX EDITOR
A GFM engine, built from scratch. Live-preview editing and a streaming AI renderer.
Lattice
SPREADSHEET EDITOR
An XLSX-grade grid, formula engine and chart renderer. In the browser, built from scratch.
Lectern
AI-NATIVE PRESENTATIONS
Decks that generate on-brand and stream onto the canvas. Underneath, it's a real editor.
GridMD
OPEN SPREADSHEET FORMAT
Markdown for spreadsheets: full XLSX fidelity, in diffable plain text an LLM can author.
Open cores
MIT engines and an open format. Pro extensions fund the work.
Native where it counts
Typewright and Lattice ship as Swift-native apps on macOS, iOS and iPadOS.
One text family
Markdown for documents. GridMD for workbooks. Diff, merge and stream all of it.
