I developed Antalogy - free and 100% local-first Word-like Markdown Editor for Windows and macOS

Hi everyone,

We often invest our efforts in what we ourselves lack. At the end of last year, in parallel with my main business, I decided to try to implement an idea I deeply and sorely needed - a desktop "Word for Markdown" with an integrated AI Assistant - Antalogy.

This side project was developed with some old colleagues in free time from the main business since the end of 2025.

I'm done overpaying for cloud subscriptions and AI tokens just to edit my own text. I don't want my private data silently processed in the background or ending up in someone else's training set. I want to write on a plane or at the beach without an internet connection. Business documents and financial figures are confidential - they should stay on your device, period.

Antalogy is 100% local. It reads and writes clean .md files. Word documents in .docx can be just opened to be converted and saved as markdown just in one-click. No telemetry. No vendor lock-in. No surprises.

The Tech Stack:

• Backend & Core: Built with Go, handling all local file I/O, .docx parsing, and LLM endpoint routing.

• Frontend & UI: Built with Svelte, allowing us to create a highly responsive, rich-text ribbon interface without Virtual DOM overhead.

• Desktop Architecture (Wails): We explicitly chose Wails over Electron to leverage the OS native webview (WebKit on macOS / WebView2 on Windows) instead of bundling a heavy, embedded Chromium instance. This keeps the binary lightweight and ensures a minimal RAM footprint.

• Supply Chain Security: We don't pull third-party libraries from npm during build time. All dependencies are strictly vendored and frozen locally within the repository. This guarantees 100% reproducible builds, eliminates supply chain vulnerabilities, and ensures no untrusted code can ever slip into the application.

This is a preview version. I might be wrong about the demand for this UI style. I’d love your honest feedback: would you use a local, ribbon-driven Markdown editor that bridges the gap between classic word processing and LLM optimization, or do you strictly prefer dev-centric/hotkey-heavy tools?

Cheers,

Serge

P.S. This is not just one more weekend vibe-coded app, with 30 years in software industry including Borland and Microsoft as well as created own startup from the idea to M&A, I undertand the product have to be deeply architectured, otherwise no way to have future. At the same time functionality have to meet user needs and your voice is highly important for me.
