Ophel

Hi, I'm the independent developer behind Ophel.

Ophel was born from the real pain points I faced when using AI in my daily work. As a heavy AI user, I switch between ChatGPT, Claude and Gemini every day to handle tons of code debugging, document writing and creative brainstorming tasks.

As I used these tools more, I ran into three unbearable issues:

1. Too many "floors" to get lost in: Long conversations often have dozens of rounds. If I wanted to go back and find a specific knowledge point or code snippet, I had to scroll frantically, which was extremely inefficient.
2. Messy session lists: Official sidebars only list sessions by timeline, so hundreds of historical conversations get piled together. Finding that architecture plan I discussed last week was like looking for a needle in a haystack.
3. Subpar reading experience: The narrow middle of the screen not only wastes monitor space, but is also unfriendly for reading long-form content.

I started thinking: why does AI have to be just a simple chat window? Shouldn't it be a more powerful productivity tool?

So I decided to develop Ophel. My original goal was simple: turn linear, fragmented AI conversations into structured, easy-to-manage knowledge assets.

🧩 What problems does it solve?

Ophel is dedicated to solving the "last mile" experience issues in AI interaction:

• Say goodbye to "elevator-style" searching: Visualize long linear conversations with a smart outline, so you can browse conversations just like reading an e-book.
• End "one-off" sessions: Use folder classification, tags and search to turn your AI sessions into a well-organized private knowledge base, no more disposable chat logs.
• Break "platform" barriers: Whether you prefer Gemini's long context window, Claude's strong reasoning, or ChatGPT's all-round capabilities, Ophel delivers a unified, top-tier enhanced experience for all mainstream platforms.

✨ Core Feature Highlights

Ophel is not just a simple UI beautification script, it's a full-featured AI interaction enhancement suite:

1. 🧠 Smart Outline & Quick Navigation

This is Ophel's most popular feature. It automatically parses user questions and AI replies to generate a clickable directory structure in real time.

• Bidirectional navigation: See every one of your questions clearly in the outline, and jump to them instantly with one click.
• Lifesaver for long content: Whether it's a long paper, code explanation or novel draft, the outline gives you a clear view of the content structure, no more frantic scrolling to find context.

2. ⚡ Prompt Library

No more copying and pasting prompts from notepads. Ophel has a powerful built-in prompt management feature:

• Variable support: Use preset templates to generate prompts by filling in blanks.
• One-click send: Favorite commonly used instructions and send them with one click.
• Categorized management: Organize your prompts like "academic polishing" and "code audit" neatly into categories.

3. 💬 Powerful Session Management

If the official features aren't enough, Ophel has you covered. It takes over your sidebar to provide:

• Folder system: Archive sessions by project or topic.
• Full-text search: Instantly find key information in historical conversations.
• Batch management: Clean up or export sessions with one click.

4. 🎨 Immersive Reading & Customization

• Auto wide-screen: Makes full use of large screen space for more comfortable reading of code and long-form content.
• Theme customization: Comes with 20+ beautiful color schemes (dark/light), supports custom CSS to make your AI interface one of a kind.
• Reading progress recovery: Automatically returns you to your last reading position even after refreshing the page.

5. 🔒 Privacy & Sync

• Seamless sync: Supports WebDAV (such as Nutstore, iCloud, etc.) to achieve seamless sync of configuration and session data across multiple devices.
• Privacy-first: All data is stored locally first, no user chat content is collected.

🛠️ Why choose Ophel?

• All-in-one: One plugin works for all mainstream platforms including Gemini, ChatGPT, Claude, AI Studio, Grok and more.
• Extremely lightweight: Built on React + Plasmo, silky smooth performance with no intrusive feel.

I hope Ophel can be your capable assistant in exploring the AI world, making every conversation more valuable.
