Chat your way to a finished .docx (or .pptx, or .xlsx)

What it does

OfficeDex is a desktop workspace—built with Wails v2, React 19, and Go—that generates native .docx, .pptx, and .xlsx files from natural language prompts. You describe a Q3 sales report or a pitch deck, and a separate officecli subprocess (communicating via JSON-RPC) assembles the actual OOXML file. The app renders a live preview inline, so you never need to open Microsoft Office to check the result.

The interesting bit

Instead of exporting HTML and praying, OfficeDex treats document generation like software development: it claims to understand OOXML “syntax,” template “frameworks,” and layout “design patterns,” with multiple agents handling structure, content, and formatting separately. It also remembers your style choices across sessions, so your fiftieth report inherits the same heading hierarchy and color scheme as your first.

Key highlights

• Native OOXML output—no HTML intermediates or manual copy-paste cleanup
• Inline preview for Word, PowerPoint, Excel, and PDF without an Office install
• Bring-your-own-LLM: works with OpenAI, Anthropic, Azure, or self-hosted models, and can run fully offline with a local officecli binary
• Notion-inspired UI (purple #5645d4, 8 px buttons, DM Serif Display) wrapped in a Wails desktop shell the README claims is under 30 MB
• Multi-agent pipeline where the AI asks clarifying questions mid-flight if it is unsure about structure or content

Caveats

• The macOS binary is not Apple-notarized, so Gatekeeper blocks first launch and requires manually stripping the quarantine attribute
• The generation engine relies on a separate officecli binary that must be present or auto-downloaded; it lives in a separate repository

Verdict

Worth a look if your job involves repetitive templated documents and you would rather describe intent than wrestle with slide masters. Skip it if you need a collaborative, browser-based editor—this is a local-first desktop experience.
