What can I do with v0.1 today? +
Open, edit, and save `.flexstats` bundles. The Markdown editor has a live preview of prose — headings, paragraphs, lists, tables. Chart, table, and KPI blocks show placeholders; they're parsed and preserved on save, but rendering lands in v0.3+. Data import, chart rendering, and PDF export arrive in v0.2–v0.6.
Is the file format open? +
Yes. `FILE_FORMAT.md` is published under CC BY 4.0. Any tool can read or write `.flexstats` bundles in any language. The format is a macOS package with `dashboard.md` as the source of truth and CSV data under `data/` — no proprietary container.
Does my data stay on my Mac? +
Yes. No cloud, no telemetry on file contents, no column names leaving the device, no third-party analytics. All AI features (when they land) run through Apple's Foundation Models framework on-device. If a file goes somewhere, it's because you sent it.
Can I edit the Markdown directly? +
Yes. `.flexstats` is a package — Finder shows it as one file, but it's a folder with `dashboard.md` inside. Power users can edit the Markdown in any editor, diff it in Git, and commit it. Round-trip is tested: parse → serialize → parse yields an identical AST.
Is this a replacement for Tableau, Power BI, or Excel? +
No. flexStats is a dashboard authoring tool for people who don't want to learn a BI platform — not a live-data dashboarding service, not a multi-user collaboration suite, and not an Excel competitor. It's the tool for people who stare at a quarterly report and wish they could just "make it look good."
What chart types are supported? +
Eleven: bar, line, area, scatter, pie, donut, heatmap, waterfall — plus scatter3d, bar3d, and surface on macOS 26 via Chart3D. Six palettes, eight themes. Multi-series, tooltips, and responsive sizing across every chart view.
What macOS version do I need? +
macOS 26 (Tahoe) for the v1.0 build. The app uses Chart3D, Foundation Models, and Liquid Glass — all of which require macOS 26. Earlier builds may run on older systems, with 3D charts and on-device AI hidden where not supported.
What about Windows, Linux, or the web? +
No. flexStats is a macOS-first app using Swift, SwiftUI, Swift Charts, and PDFKit. The file format is open — a Windows implementation could exist; we just won't be the ones to write it.
