😫 The Problem

You've spent hours crafting the perfect prompt. It works beautifully. But then...

• 📋 It's buried in a note app you'll never find again
• 🔄 You rewrite it from scratch every single time
• 🤦 You paste it, then realize you forgot to change the [topic] placeholder
• 🚫 You can't share that killer prompt with your team without copy-pasting

Prompt Ark fixes all of this.

2. Click the 🧩 Puzzle icon in your toolbar → Click 📌 Pin next to Prompt Ark

💡 Prompt Ark also supports Side Panel mode — click the extension icon to dock it as a persistent sidebar.

Step 2: Zero Config — It Just Works

Prompt Ark ships with Gemini Web as the default AI backend. As long as you're logged into gemini.google.com, all AI features work immediately:

Feature	Status	What you do
✨ Prompt Picker	✅ Always works	Just click
⚡ Quick Actions (Rewrite, Translate...)	✅ Always works	Just click — uses the platform's own AI
🔮 AI Prompt Optimization	✅ Works by default	Be logged into Gemini
🏷️ Auto-extract title/category/tags	✅ Works by default	Save a prompt without filling in a title

💡 No API key. No setup wizard. Just install and use.

Want faster responses or a specific model? Go to Settings → Models → + to add a Web-session provider, Gemini API, or any OpenAI-compatible API. See Model Configuration.

Step 3: Create Your First Prompt

Prompt Ark uses a structured category system. You can choose from system categories, reuse your own custom categories, or review AI recommendations when the match is uncertain.

⚡ Power Moves

One-click text transforms

The ⚡ button appears next to every AI chat input. Click it to instantly:

✏️ Rewrite · 📋 Summarize · ➕ Expand · 🌐 Translate · 💡 Explain

No API key needed — these use the platform's own AI.

Dynamic variables — 3 types

Write variables in your prompt content and they become fill-in forms at use time:

Syntax	Type	Example
{{topic}}	Free-text input	Any text
{{lang:EN|ZH|JP}}	Dropdown (enum)	Pick one option
{{style:formal}}	Pre-filled default	Editable, pre-filled

Prompt taxonomy

Prompt Ark now separates prompt organization into:

Layer	What it means
Output modality	Text · Image · Video
System categories	10 stable domains such as Productivity, Writing, Marketing, Coding, Data, Design
Custom categories	Your own reusable labels
AI review state	Low-confidence AI classifications are marked for confirmation before sharing/publishing

Context variables ({{@...}})

Use {{@page_title}}, {{@page_url}}, {{@selection}}, {{@date}} to auto-fill live context from the current browser tab — no typing needed.

Grab Context (Ctrl+Shift+G) creates a Smart Convert prompt card with source context from the current page. {{@variable}} context variables still resolve from the current tab when the prompt runs.

Slash commands

Type /email in any chat box → Your "Professional Email Writer" prompt expands instantly. Like text shortcuts, but for AI.

AI Prompt Optimizer

Click ✨ Optimize on any prompt → Get 3 professional rewrites (Concise / Enhanced / Professional) with diff view. Accept with one click.

AI Prompt Translation

Translate any saved prompt into 7 languages with one click — directly from the prompt list or the edit modal.

• Click the 🌐 button on any prompt card in the list
• Choose: English · 中文 · 日本語 · Español · Français · Deutsch · 한국어
• The title, category, tags, and content are all translated and auto-saved
• If your Gemini session expires, the login page opens automatically

Uses your configured AI provider (Gemini Web by default — no API key needed).

🪄 Smart Convert

Select any text on any webpage → Right-click → "Smart Convert to Prompt". AI infers the intent, adds a role, structures it with variables, and saves it as a reusable prompt — no manual editing needed.

One-click Social Sharing

Share a prompt with an AI-generated post — tailored per platform: Twitter · Reddit · Zhihu (知乎) · WeChat (微信) · Xiaohongshu (小红书)

Right-click to save

See a great prompt on a webpage? Select text → Right-click → "Add to Prompt Ark". It's saved with AI-generated title, category, and tags.

Page-aware prompts

Use {{@page_title}}, {{@page_url}}, {{@selection}}, {{@page_text}} in your prompts — they auto-fill with live content from the current tab.
