Per-site settings: model lock, Markdown fixes, and Claude

Different AI platforms have different page structures, behaviors, and account models. Ophel lets you configure settings independently for each site rather than applying a single global configuration. Go to Settings → Site Settings: Page Layout and Model Lock apply to the site you are currently on, while the Gemini, AI Studio, ChatGPT, and Claude tabs hold each platform’s own options.

​

Model lock

Model lock solves a common annoyance: manually switching back to your preferred model every time you open an AI platform. Once configured, Ophel checks the model selector after the page loads and switches to your target model automatically. If the target model isn’t available on your account, Ophel leaves the current selection untouched. To set up model lock:

1. Open the target AI platform, then go to Settings → Site Settings → Model Lock
2. Toggle it on
3. Enter a keyword from the target model’s name (matching is case-insensitive)

Each site’s model lock setting is independent, so you can configure different target models for different platforms. You can also toggle model lock for the current site quickly from Toolbox → Model Lock. Supported sites:

​

Markdown rendering fixes

Some AI platforms have intermittent Markdown rendering bugs — bold text failing to render is a common example. Ophel provides site-specific toggles to patch these issues without affecting other platforms. The fix is off by default on all three platforms — enable it only when you actually see rendering problems.

​

Gemini watermark removal

When you export or screenshot a Gemini conversation, Gemini appends a “Created with Gemini” watermark. Ophel can strip this watermark automatically. Settings → Site Settings → Gemini → Remove Image Watermark The same watermark removal option is also available for AI Studio under Settings → Site Settings → AI Studio → Remove Image Watermark.

Gemini Enterprise: policy retry

​

AI Studio settings

Settings → Site Settings → AI Studio provides controls for the initial state of various sections on the AI Studio page, so you don’t have to collapse them manually every time you open it:

​

Claude session key management

Claude accounts have usage rate limits. When one account hits its cap, you normally have to wait for a reset. If you have multiple Claude accounts, Ophel can store Session Keys for all of them and let you switch instantly — keeping the conversation going without logging out and back in. A Session Key (sk-ant-sid... format) is the authentication token your browser session uses on claude.ai. Ophel injects the specified key into requests so you can switch accounts without a full logout cycle. Keys are stored locally in your browser and are never sent to Ophel’s servers. Adding a session key — go to Settings → Site Settings → Claude: Switching between accounts: After switching, Ophel refreshes the current Claude page to apply the new key. Managing the key list:

​

Usage monitor

For AI services with daily usage limits, Ophel provides a local counter that shows how many conversation turns you have used today and roughly how many tokens were consumed. The usage monitor runs entirely locally — it does not call any external APIs or rely on usage data from the platform. Ophel counts turns and estimates tokens by observing messages on the page. Settings → Features → Alerts → Local Usage Counter & Estimate: When enabled, the widget shows today’s send count, input/output character stats, rough token estimates, and progress toward your daily limit.
