Mermaid diagram rendering
Some AI platforms display Mermaid code blocks as raw text instead of rendered diagrams. When Ophel detects an unrendered Mermaid block, it renders the diagram in place automatically. Settings → Features → Content → Render Mermaid in AI replies (default: on)This only activates when the platform itself has not rendered the Mermaid
block. It will not interfere with native diagram rendering.
Formula rendering and source copy
When an AI reply contains math, Ophel recognizes LaTeX delimiters and renders the formulas inline. To copy the source from any supported rendered formula, double-click it — Ophel copies the selected source format to your clipboard immediately. Settings → Features → Content → Double-click to copy formula (default: on)Formula copy format
Choose whether double-clicking a formula copies:- LaTeX source — best for Markdown notes, TeX editors, Obsidian, Typora, and most AI prompts
- MathML source — best for accessibility workflows, web documents, and tools that preserve structured math markup
Some sites expose only visual formula HTML and no stable source. In that case,
Ophel shows a message instead of copying an unreliable result.
LaTeX delimiters
When the copy format is LaTeX source, Ophel can add delimiters before placing the text on the clipboard:- Inline formulas use
$ ... $ - Block formulas use
$$ ... $$
User message Markdown rendering
Markdown syntax you type in the AI input box —**bold**, `code`, - list item — normally appears as plain text in your message bubble after sending. With this feature enabled, Ophel renders Markdown formatting inside your messages so they’re easier to read.
Settings → Features → Content → Render Markdown in user messages (default: on)
Markdown table copy
A Copy button appears on tables inside AI replies. Clicking it copies the table as standard Markdown table syntax, ready to paste into any Markdown editor. Settings → Features → Content → Copy Markdown tables (default: on)Conversation export
Export any conversation to a file from Toolbox → Export. The quick button exports Markdown; the Conversations tab row menu also lets you choose JSON or TXT.Markdown (.md)
Markdown (.md)
Exports the full conversation with speaker labels and message content
formatted as Markdown. Useful for pasting into notes apps, wikis, or
documentation.
JSON (.json)

Exports structured data including metadata. Useful for programmatic
processing or archiving.
Plain text (.txt)
Plain text (.txt)
Exports a clean, unformatted transcript.
| Setting | Description |
|---|---|
| Custom user name | Replaces “Me” in exported files; leave blank to use the default |
| Custom AI name | Replaces the AI’s name in exported files; leave blank to use the platform name |
| Include timestamp in filename | Appends a timestamp to the filename to avoid overwriting existing exports |
| Include chain of thought | Include the AI’s reasoning content in exports (Claude, Kimi, Qwen Studio, Yuanbao, Z.ai, ChatGLM, Ima) |
| Packaging mode | Markdown only exports a single .md file; Zip package bundles the Markdown with referenced images and files as a .zip |
Platform-specific fixes
Markdown fix (Gemini, AI Studio, ChatGPT)
Markdown fix (Gemini, AI Studio, ChatGPT)
These platforms sometimes fail to render bold text correctly —
**text** appears as literal characters instead of formatted output. Ophel includes a patch for each affected platform.- Settings → Site Settings → Gemini → Markdown fix

Watermark removal (Gemini, AI Studio)
Watermark removal (Gemini, AI Studio)
Gemini and AI Studio can attach “Created with Gemini” watermarks when exporting or screenshotting certain content. Enabling this removes those watermarks.This feature requires the optional
<all_urls> permission (used to fetch images and convert them to base64). The browser will prompt for permission the first time you enable it.Settings → Site Settings → Gemini → Remove watermark
