Four ways to work
Write how you think, not how Markdown thinks.
Switch modes anytime – your document stays the same plain .md file underneath every one of them.
Source
Full raw Markdown source with syntax highlighting. The mode for power users who want complete control.
Split
Source and live preview side by side. Write in Source and review the rendered result alongside it.
Visual
Block-based editing for headings, paragraphs, simple tables, checklists, and images. Complex blocks open in Source mode to preserve their Markdown.
★ Signature feature
Preview
Clean rendered output. Review your document before exporting or sharing; its appearance in another app depends on that app’s Markdown renderer.
What makes Nicostrata different
The features writers keep asking for.
Visual Mode
Write with guided blocks. Keep your Markdown.
Visual mode offers guided editing for headings, paragraphs, simple tables,
checklists, code, and images. Complex blocks open in Source mode so you can
preserve their Markdown. Your document remains a plain .md file.
Use Visual for everyday writing and Source when you need precise control.

Compatibility Checks
Check common formatting risks before you share.
Nicostrata’s Document Assistant checks common compatibility risks for
General Markdown, GitHub, Obsidian, Reddit, and Website targets.
These checks flag formatting that may need attention before you share;
they do not guarantee identical rendering in every destination.
Supported Fix actions make targeted changes for you to review.
Export
Four ways out. All of them clean.
Export HTML with local images embedded or copied to an assets folder,
create a PDF, package Markdown with its local assets, or copy rendered HTML.
Preview and export share the CommonMark/GFM renderer; export themes and
the destination app can change the appearance. Remote image references
remain remote in HTML and Markdown packages.
Also built in
Everything else you’d want from a serious writing app.
Folder Browser
Choose a folder you can access, then browse, create, rename, and delete Markdown files from the workspace. On iPad, use Files to choose local, iCloud Drive, or supported provider locations.
Focus Mode
Reduce the surrounding controls with Focus mode. Typewriter scrolling helps keep the current source line centered while you write.
7 Built-In Templates
Start from a GitHub README, blog post, meeting notes, product spec, release notes, or documentation page. Save your own templates too.
Find & Replace
Search the Markdown source with case-sensitive and whole-word options. Review matches, replace one at a time, or use Replace All.
Custom Preview Themes
Choose Default, GitHub, Minimal, or Solarized. Or paste your own CSS. Preview styling never bleeds into your exports unless you explicitly choose a theme at export time.
Word Goals & Session Tracking
Set a target word count per document. Watch a live progress bar fill as you type. A daily session counter resets at midnight so you can track how much you wrote today.
Table Tools
Insert a table visually, then add and remove rows and columns by clicking – no pipe characters or manual cell spacing required. The saved file is always clean, standard Markdown.
Link & Image Validation
Local checks flag missing images and fragile paths. Remote URL checking is off by default; enabling it sends link and image URLs directly to their servers for advisory reachability checks.
Syntax Highlighting
Source mode colors headings, bold, italic, links, code fences, blockquotes, and list markers so the raw source is readable at a glance – without changing the file.
See it in action
Every mode. One clean window.
Who it’s for
One app. Three very different reasons to use it.
