🚀 Mayhem Browser - Ultimate AI Flashcard Companion & Embedded Web Browser for Anki

Mayhem Browser brings the power of frontier AI models and medical/academic reference databases directly into your Anki flashcard reviewing workflow. Featuring a draggable Reviewer HUD, persistent logins, verified 1-click card context prompting, answer capture straight back into your notes, multi-layout display modes, and instant text-selection queries.

✨ Key Features

1. 🎯 Draggable Reviewer HUD

• Main Action Button: Displays the crisp brand badge of your currently selected AI site (ChatGPT, Gemini, Claude, Grok, Perplexity, DeepSeek, etc.). Clicking it opens/toggles the browser loaded directly with that site — or sends the current card instead, if you would rather it did that.
• ⚡ Send Button: Fires your default prompt preset at the active site in one click.
• ⬇️ Grab Button: Lifts the AI's latest reply off the page and into the scratchpad.
• Switcher & Settings: Opens a sleek, glassmorphic Quick-Switcher modal directly in the reviewer. Selecting any site immediately transforms the main button in real-time, changes the active provider, and updates the browser view!
• Speed-Dial Chips: Put your most-used prompt presets — including ones you wrote yourself — on the HUD as 1-tap chips.
• Drag it anywhere (position is remembered across card flips), minimize it to a compact bubble, scale it, or dial its resting opacity down so it fades into the card until you hover it.
• 8 Themes: Glass Dark, Cyberpunk Neon, Dracula Neo, Emerald Mint, Sunset Glow, Nordic Frost, OLED Pure Black, and Porcelain Light (for those of you on white cards).

2. 🤖 27 Built-In AI Providers & Reference Engines (+ Custom URLs)

Enable only the ones you actually use — the rest stay out of the switcher, the HUD and the Tools menu.

3. ⚡ 1-Click "Send Card to AI" — Verified, Not Hopeful

Extracts question, answer, and notes (stripping Anki cloze syntax, HTML, sound, and image tags) and formats it into proven active-recall prompt templates.

The prompt is confirmed to actually be present in the site's chat box before Send is pressed. No more silent half-sends into a page that was still loading. If it cannot be confirmed, the page shows a notice and the prompt stays on your clipboard, ready for Ctrl+V.

Injection is provider-aware and React-safe, retries while a single-page app is still booting, and can fall back to the Enter key when no Send button exists. Auto-submit is optional — turn it off to read the prompt before it goes.

13 built-in presets:

• 👶 Explain Simply (ELI5): Breaks down complex concepts with intuitive real-world analogies.
• 🧠 Memory Mnemonic: Generates creative, vivid mnemonics and mental imagery for tough cards.
• ⚡ High-Yield Exam Summary: Isolates core high-yield buzzwords, testable points, and common traps.
• ❓ Active-Recall Practice Questions: Generates 3 challenging practice questions with hidden answers.
• 🔬 Deep-Dive Mechanism: Breaks down physiological, biochemical, and logical mechanisms step-by-step.
• ⚖️ Compare & Contrast: Differentiates look-alikes and common confusions in a clear summary.
• 🩹 I Got This Wrong - Fix My Gap: Diagnoses the misconception behind a lapse and patches it.
• 🃏 Draft Follow-Up Flashcards: Turns one card into a set of new atomic cards, table formatted.
• 📌 Condense to Note Block: Produces a tight bullet block sized for pasting into a field.
• 🗺️ Structured Breakdown: Nested outline across the standard axes of a topic.
• 🌍 Translate & Explain: Translation plus a glossary of the technical terms.
• 📚 Verify With Sources: Fact-checks the card and asks for citable sources.
• 📝 Direct Card Content: Sends only the raw cleaned card text, with no instructions attached.

4. ✏️ Prompts Are Fully Yours to Edit

• Write your own from scratch, or duplicate a built-in and tweak it.
• Edit any built-in preset. Your wording is stored as an override, so an add-on update never clobbers it — and "Revert" always restores the shipped text.
• Hide the presets you never touch so the menus stay short.
• Promote any preset — yours or ours — onto the HUD as a speed-dial chip.

Template placeholders: {card_text} {front} {back} {selection} {deck} {tags} {note_type} {field:YourFieldName} {date}. Anything else in braces is left alone, so JSON, LaTeX and code inside a template survive intact.

Fine-grained control over what actually gets sent: cap the character count, label each field with its name, exclude specific fields (Audio, Source…), skip the field Mayhem writes into so old AI answers are not fed back, and choose whether the answer side travels with the question.

5. ⬇️ Grab Answer & Save It Into the Card

Press Ctrl+Shift+G (or the HUD's ⬇️ button) and the AI's latest reply drops straight into the scratchpad. Pick any field on the current note, choose Append / Prepend / Replace, and save. The card redraws immediately, so you see the result without waiting for the next review.

The AI's Markdown is converted into clean, Anki-safe HTML by a real block parser:

• Headings, bold, italic, ~~strikethrough~~, inline and fenced code
• Ordered, unordered and nested lists, plus task lists
• GitHub-style tables, honouring per-column alignment
• Blockquotes, horizontal rules, links and images
• Everything else is HTML-escaped, so a stray < in an answer stays visible instead of being swallowed as markup

Three note styles: Adaptive (translucent greys that stay readable on light and dark cards), Dark (vivid palette), or Plain (bare semantic HTML you style yourself from your note type's CSS via .mayhem-ai-note). Optionally wrap each note in a labelled, timestamped callout box.

6. 🔒 Persistent Logins & Cookies

Uses a dedicated persistent QWebEngineProfile stored outside the add-on folder, so you stay permanently logged into your ChatGPT, Claude, Gemini, and Grok accounts across Anki restarts — and an update never trips over a locked file. The AI Login Hub gets you signed into every site from one place.

Mayhem also remembers the last page you were on per site, so a Custom GPT, a Gem or a NotebookLM project reopens exactly where you left it.

7. 🖥️ Multiple Window & Layout Modes

• Docked Side Panel (Split Reviewer): Docks seamlessly beside your card with adjustable width percentage (25% to 75%) without obscuring the flashcard.
• Floating Glass Overlay: Draggable, resizable overlay directly above the reviewer.
• Independent Standalone Window: Complete multi-tab desktop browser with omnibox, find-in-page, zoom controls, and always-on-top toggle.

8. 🔍 Highlight-to-Search & Native Right-Click Menus

When you highlight text on any flashcard, a floating ⚡ Ask AI chip pops up to query the active AI site with 1 click. Mayhem also adds entries to Anki's reviewer right-click menu — ask the active site about your selection, run any prompt preset against it, toggle the browser, send the whole card, or grab an answer — without ever reaching for the HUD.

⌨️ Default Keyboard Shortcuts
