DeMinds Editor: Keep working on what you read

Edit visually in Rich, make precise changes in Markdown, and check the result in Preview.

An imported article or a note in progress often needs another sentence, a better heading, or an image. DeMinds Editor keeps those changes in the same Working Markdown, so you can finish reading today and return to refine it later.

DeMinds 1.0.45 adds Rich editing and the ability to insert and reuse project images, making everyday updates more direct. Markdown source, Preview, and Universal Mind Map remain available to help you check both the content and its structure.

One document, different ways to work

You do not have to choose between being a “source editor” person and a “visual editor” person. Open Preview to read, use Rich when available to refine the text, and switch to Markdown when you need to inspect syntax or image paths.

Both editing surfaces work on the same Working Markdown. There is no separate rich-text file for you to keep in sync.

Use one editor at a time: Markdown or Rich. During editing, Preview lets you read the draft. The Working Copy and Universal Mind Map update only after a successful save.

Where does Universal Mind Map fit in?

Universal Mind Map helps you see the overall structure and find the part you want to read. The document area handles reading and editing, so the two work together.

With enough document space, you can open the text and mind map side by side, then choose Preview, Markdown, or Rich in the document pane. While you edit, the mind map shows the last saved content. It reflects your changes only after a successful save.

Try a small edit, from reading to saving

Start with one of your own ordinary Markdown notes, or an imported project you can edit. A small, easy-to-check change is a good way to get familiar with the three surfaces.

1. Find something to refine in Preview

Open the current Working Copy and read through it. Perhaps a section needs a subheading, or an explanation needs updating. If you are viewing the Baseline or a historical version, return to the current Working Copy before editing.

2. Choose Rich and edit the content directly

Select Rich from the surface menu. Once the document passes compatibility checks, you can edit the text visually and use the available actions in Format to adjust headings, emphasis, lists, and more.

For example, turn a short section title into a level-two heading and add a sentence with your own interpretation underneath. When editing an ordinary table, use the row and column controls that appear when the table has focus.

If Rich is unavailable, choose Markdown to continue. Rich availability depends on the actual contents of the document; there is no need to remove important content just to enable it.

3. Return to Markdown for precise control

Markdown shows the actual source when you need to check a heading level, change a link destination, or inspect a relative image path.

If you have unsaved changes when switching between Markdown and Rich, follow the prompt to save, explicitly discard those changes, or cancel the switch. Save first if you want to keep your edits. Switching surfaces does not, by itself, mean the document has been saved.

4. Check Preview, then confirm your save

During editing, you can switch to Preview to check how the current draft reads. Previewing a draft does not save it. When you are satisfied, save and wait for confirmation that it succeeded.

Saving updates the Working Copy and Universal Mind Map in DeMinds. It does not directly rewrite the external file you originally imported. You can return to the project and keep editing after saving.

If saving fails or the result has not yet been confirmed, keep the editing session open and follow the guidance shown. Seeing an image or an updated preview does not confirm a successful save.

Add an image and use it again

Both Markdown and Rich can insert supported images into a writable project. You can enter an image URL or a relative resource path, or choose an image from your device.

Add an image from your device

1. While editing, open the image insertion control and choose one image from your device.
2. Check the preview and alternative text. Use the alternative text to briefly describe the image.
3. Confirm the insertion to add the image reference to the current draft.
4. Save the document to commit the new images used in the draft together with the Working Markdown.

Device image selection currently supports PNG, JPEG, GIF, and WebP. If you close the picker after selecting an image but before confirming, that selection is not inserted into the document.

Reuse an image within the same project

The next time you insert an image, you can choose from the project's existing images. Images you have already confirmed and inserted in the current session are also available before saving, with an unsaved label.

Select a thumbnail to see a larger preview, then confirm to insert it. You can also select the same thumbnail again to confirm. Reusing an image adds another reference to it; you do not have to choose the device file again.

The project image picker is for selecting and reusing images within the current project. It is not a library shared across projects, and it does not provide cropping, bulk management, or general attachment management.

Why is Rich unavailable for some documents?

Imported content may include special HTML, complex blocks, anchors, or other protected structures. Being able to read that content in Preview does not mean it can all be edited directly in Rich.

DeMinds checks whether the current document can reliably make the round trip between Rich and Markdown, and checks the reading and mind map results. If those checks do not pass, you can still maintain the content in Markdown source.

Some documents can open in Rich while parts of their content remain read-only. For example, frontmatter metadata can be preserved as written; use Markdown to edit its fields. An available Rich surface does not mean every block is directly editable.

Rich currently has a 256 KiB limit for both its input and the Markdown output it produces. This is a byte limit, not a word or character count; use Markdown source for larger documents. Rich editing may also normalize some Markdown syntax, so the source is not guaranteed to remain byte-for-byte identical.

Save now, pick up where you left off

Return to Continue Working and open the same project to keep reading and refining it. When you need to review earlier changes, use Version History to view, compare, or restore the Working Copy.

Version History has a retention limit; it is not a record of every keystroke. It currently retains the Baseline, the three most recent automatic historical versions, and one Pinned Version. Undo and redo while editing serve a different purpose from saved version history.

To continue in another tool, export a Markdown File or a Standard Markdown Bundle. For documents with images, check the export options to confirm which resources are included. Images referenced by remote URLs may still depend on a network connection and the original site.

Where can you use it?

Both editors, Preview, and the project image workflow described here are included in Standard. Plus users can use them too.

Side-by-Side requires an actual document area of at least 900 × 600. When the window becomes too narrow, DeMinds returns to a single surface. This requirement refers to the document area, not the device's screen size.

The Apple app can use a Local Workspace or an iCloud Workspace; Web does not provide a native iCloud Workspace. Files and images in iCloud must be ready to use. A successful save or a visible image does not mean another device has received the content immediately.

Open something you want to keep working on and start with one paragraph. Use Rich for visual edits, Markdown for precise control, and Preview to read the result.
