Visual finishing for existing HTML.
Chiselo is a native macOS editor for the moment after an HTML page already exists. Open the original file, select what you see in the browser rendering, make a precise visual change, review it, and deliver the original format.
中文：Chiselo 不是从零建站工具。它服务于“已有 HTML 做最后一轮精修”的工作流：打开原文件，直接选中页面上的对象，修改文字、图片、样式或布局，复核变更后安全交付。
| Work | Chiselo approach |
|---|---|
| Find the right object | Select the rendered DOM object instead of searching source first. |
| Make a local correction | Edit text, images, tables, typography, color, spacing, geometry, and layers. |
| Keep control of the source | Preserve untouched HTML byte-for-byte; write HTML and local CSS with rollback-capable saving. |
| Review before delivery | Compare visual changes, inspect responsive widths, and run delivery checks. |
| Deliver the right format | Save HTML, export high-fidelity PDF, or use best-effort editable PPTX. |
- Download the signed macOS build from Latest Release.
- Open an existing
.html,.htm, or.xhtmlfile. - Select a visible object, make the adjustment, then review the change before saving or exporting.
Current release: 0.1.25 for Apple Silicon Macs. See the installation guide and usage guide.
Chiselo is designed for static pages, reports, dashboards, visual documents, and conventional HTML generated by people or other tools. It is not a website builder, hosting product, site manager, general-purpose IDE, or prompt-to-page generator.
Scripts, forms, remote resources, cross-origin embeds, animations, canvas, and framework runtimes are diagnosed as compatibility risks. Documents open in static-safe mode by default; dynamic compatibility requires an explicit trusted document choice. PDF and PPTX export retain the safe default unless that choice has already been made.
- Product strategy: scope, primary workflow, and maintenance rules.
- Install and usage: end-user guides.
- Architecture and testing: how the app is built and verified.
- Roadmap and changelog: what is next and what changed.
- Release notes: current packaged build details.
Requirements: macOS 13+, Xcode command-line tools, Swift 5.9+, and Node.js for the helper scripts.
