Inkwell1.5.2

Inkwell lets you write, organize, and review local Markdown documents while displaying a rendered preview beside the source as you type. Built by 4Worlds for Windows x64, this portable, offline-first System Tools program keeps the writing workspace on the desktop rather than in cloud services. Its SQLite-backed persistence stores application data locally, and it is designed without user accounts or telemetry.

A workspace file tree, tabs, templates, find-and-replace, typewriter mode, and focus mode support drafting and navigation across multiple files. A command palette exposes editor actions, while four built-in themes and a custom theme creator let you adjust the writing environment. Mermaid diagrams and KaTeX mathematics render in documents, and file associations plus automatic saving when focus leaves the application suit regular file-based workflows.

Version history with a diff viewer helps inspect earlier edits, while Typst-powered PDF export and standalone HTML export present finished documents outside the editor; these export features require a one-time Pro license. Inkwell fits writers, developers, and documentation authors who maintain Markdown locally, including people preparing technical notes, shell-script prose, or documents for offline work, and it belongs to 4Worlds’ anti-SaaS portable app suite.

Version 1.5.2 corrects PDF ordered lists containing multi-paragraph items or embedded code, preserves Mermaid colors in PDF output, and supports :::mermaid fences for Azure DevOps, VitePress, and Docusaurus exports. It also adds a Render math toggle for dollar-heavy documents, PowerShell highlighting for powershell, pwsh, ps, and ps1 fences, clearer export errors with actionable suggestions, and fixes inline math pairing across line breaks.
