OptiEdit help

OptiEdit supports both everyday rich-text editing and advanced local-file/code workflows. Start with the action that matches what you want to edit.

New document

Create a browser document with rich formatting, autosave, tabs, Markdown mode, voice typing and DOCX/PDF export.

Open local file

Open text, Markdown, HTML, JSON, source files, Word DOCX and common images. Compatible browsers can save editable files directly back to disk.

Open folder workspace

Browse and edit real files in a selected folder. Workspace files are not copied into browser document storage.

AI Rewrite

Rewrite the current rich-text document. A successful rewrite is a single undoable change, so Undo restores the previous content.

Rich-text editing

  • Use Copy to copy the entire active document in one tap; rich text also preserves formatting when the browser clipboard supports it.
  • Use the formatting toolbar for headings, fonts, colors, alignment, tables, code and other rich-text controls.
  • Use headings, fonts, sizes, bold, italic, underline, strike, lists, checklists, alignment, indentation, quotes, links, images and tables.
  • Use text and highlight color controls for emphasis.
  • Open Document outline to jump between headings in long documents.
  • Use HTML source mode when you need direct HTML editing.

Markdown & voice typing

  • Switch a rich-text document to Markdown editor / preview for source editing with a live rendered preview, then return to rich text when needed.
  • Markdown files open directly in Markdown mode and save as Markdown.
  • Use Dictate / Voice typing to insert speech at the current cursor position when supported by your browser.

Code and developer tools

  • Choose a code language to apply syntax highlighting to rich-text code blocks.
  • Use Tab / Shift+Tab for code indentation and the formatter for pasted code.
  • Folder and local source files open in the dedicated code editor with Find, Wrap and Copy controls.
  • JSON and XML/HTML formatting tools are available from the rich-text toolbar.

Documents, files and export

  • Source icons identify browser documents, linked disk files and folder workspace files.
  • Browser documents support rename, duplicate, delete, tabs, autosave and full-library backup.
  • Import TXT, Markdown, HTML, DOCX, common image formats and OptiEdit JSON backups.
  • Export editable documents as Microsoft Word DOCX, PDF, HTML, legacy Word-compatible DOC, Markdown, plain text or OptiEdit JSON. Images open in a safe preview instead of being decoded as text.

Keyboard shortcuts

  • Save: Ctrl/Cmd + S
  • New: Ctrl/Cmd + Alt + N
  • Find & replace: Ctrl/Cmd + F
  • Undo / Redo: Ctrl/Cmd + Z / Ctrl/Cmd + Shift + Z
  • HTML source mode: Ctrl/Cmd + Shift + H

Storage, privacy and offline use

Browser documents are stored locally using IndexedDB. Folder workspace files remain in the folder you selected. OptiEdit can work offline after its app resources have been cached. Document text is sent to the configured enhancement service only when you explicitly run AI Rewrite.
