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

Configure model lock, Markdown rendering fixes, Gemini watermark removal, Claude session key management, and usage monitoring on a per-site basis.

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 and select a site from the left sidebar to see its available 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 Settings → Site Settings
2. Select the site you want to configure
3. Find the Model Lock section and toggle it on
4. Enter a keyword from the target model’s name (matching is case-insensitive)

You only need part of the model name. Entering flash matches Gemini 2.0 Flash. If multiple models match, the first match is selected.

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 the Toolbox menu.

If you manually switch to a different model during a session, model lock only kicks in again on the next page load — it won’t override your manual selection mid-session.

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.

Site	Setting	Default
Gemini	Markdown fix — fix intermittent bold text rendering failures	On
AI Studio	Markdown fix — fix bold text rendering failures on AI Studio	Off
ChatGPT	Markdown fix — fix intermittent bold text rendering failures	Off

Enable the fix for a site only if you actually see rendering problems — it is off by default on sites where the issue is less common.

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 watermark

Watermark removal requires the <all_urls> host permission, which Ophel will ask you to grant the first time you enable this setting. This permission lets Ophel intercept and modify the export request before it reaches the page. The setting is off by default.

The same watermark removal option is also available for AI Studio under Settings → Site Settings → AI Studio → Remove watermark.

Additional Gemini settings

Settings → Site Settings → Gemini:

Setting	Description	Default
Follow page theme	Automatically sync the Ophel panel theme with Gemini’s light/dark mode	On

Settings → Site Settings → Gemini Enterprise only:

Setting	Description	Default
Policy retry	Automatically retry requests blocked by enterprise content policies (for false-positive triggers)	Off
Max retries	Maximum consecutive retries when policy retry is enabled	3

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:

Setting	Description	Default
Collapse left nav	Auto-collapse the left project navigation bar on load	Off
Collapse run settings	Auto-collapse the entire right-side run settings panel	Off
Collapse tools panel	Auto-collapse the “Tools” subsection inside run settings	Off
Collapse advanced options	Auto-collapse the “Advanced” subsection	Off
Enable search tool by default	Auto-enable Google Search when entering Prompt or Free mode	On
Default model	Model ID to auto-switch to when AI Studio loads	(empty)

The Default model setting on the AI Studio page is separate from the general Model Lock feature. Configure AI Studio’s default model here in the site-specific settings, not on the Model Lock section.

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:

Auto-import (recommended)

Click Import current session. Ophel reads the Session Key for your currently logged-in Claude account directly from your browser’s cookies — no manual copying required.

Auto-import requires the cookie access permission for claude.ai. Ophel will prompt you to grant it if needed.

Manual add

Click the Add button and paste a Session Key string in sk-ant-sid... format. You can add a label to each key to identify which account it belongs to.

Switching between accounts:

Toolbox menu

Open the Toolbox menu, click the currently active key, and select a different one from the list.

Keyboard shortcut

Press Ctrl+Alt+S (Mac: Cmd+Option+S) to switch to the next key in your list.

After switching, Ophel refreshes the current Claude page to apply the new key.

Managing the key list:

Action	Description
Set as current	Make a specific key the active account
Test single	Send a lightweight request to verify the key is valid and not rate-limited
Test all	Validate all keys in sequence, with 500 ms between tests to avoid triggering rate limits
Export	Export all keys as a JSON file for backup
Import	Restore a key list from a JSON file
Delete	Remove a single entry — does not affect the Claude account itself

Exported JSON files contain the full Session Keys. Anyone with the file can use your account’s quota. Be careful when sharing WebDAV backups or local files that contain exported keys.

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 → Usage Monitor:

Setting	Description	Default
Enable	Show the usage monitor widget near the input field	Off
Daily limit	Your expected daily usage cap (used for the progress bar)	100
Auto reset	Automatically reset the count at midnight	Off

When enabled, the widget displays:

• Number of conversation turns today
• Estimated input token count
• Estimated output token count
• A progress bar showing used / daily limit

Token estimates are based on character counting and may differ from the platform’s actual billing. Treat them as a rough reference, not an exact measure.
