Choose VS Code when Markdown belongs inside a software project with source control, code and development tooling. Choose Telescopo when the task is writing, reviewing or reading the document on Apple devices, with fewer development controls around it.
Where Visual Studio Code fits
VS Code’s built-in Markdown preview supports Mermaid and KaTeX math, plus synchronized source and preview scrolling. Its Markdown tools include heading navigation and link assistance. You do not need to install a Mermaid extension merely to get the built-in rendering described in its current documentation.
VS Code Markdown preview, Mermaid and math
Compare the working day
| Decision | Visual Studio Code | Telescopo |
|---|---|---|
| Workspace | Code editor with development tools and extensions | Document library with reader, editor and export controls |
| Technical rendering | Built-in Mermaid and math preview | Built-in Mermaid, ZenUML and equations |
| Editing choice | Markdown source with preview | Markdown source, supported Visual editing and Read |
| A useful pairing | Maintain repository files and review source changes | Read the same downloaded files and prepare a shareable document |
Telescopo keeps the original Markdown in its chosen folder. Use Read for review, Edit with Visual or Markdown for changes, and Split when the layout is wide enough. Navigator offers Outline and Connections. These are built-in document controls; Telescopo does not run the other app’s plug-ins or project automation.

Compare access as well as features
VS Code is a free editor for macOS, Windows and Linux. Optional services and extensions can have separate terms; compare the actual setup you use. Visual Studio Code access details.
Telescopo’s complete Markdown reader and Quick Look are free on Mac, iPhone and iPad, including Mermaid, ZenUML and LaTeX rendering. Monthly or annual App Store access adds writing, conversion on supported hardware, and export. The sample project demonstrates these workflows without starting a subscription. Earlier paid Mac and lifetime access, and the Mac-only Setapp edition, have different platform limits. Check the full access guide and current in-app offer.
What carries over—and what needs checking
You can use both apps with ordinary project files. Keep VS Code settings, extension behavior and build commands in the development workflow; they do not run inside Telescopo. Avoid unsynchronized simultaneous edits and review external-change prompts.
Work on a copy first. Keep the original until the text, attachments, links and required output are verified. Portable Markdown does not guarantee identical rendering of every extension or a transfer of app-specific history.
Try the decision on one document
Use the brief from a real repository. Check its local image, Mermaid fence and equation in both previews, then inspect a diff in your development tools. Try Telescopo for reading and PDF handoff without assuming the whole development workflow needs to move.
