PowerPrompter support

Install, organize, refine, and troubleshoot PowerPrompter — written for everyday users.

PowerPrompter helps you save, organize, and inject prompts on Claude, ChatGPT, and Gemini. Super powers refine prompts before you send them—so you get more from the AI you already use.

What is PowerPrompter?

PowerPrompter is a Chrome extension that opens in a side panel next to your chat. You save prompts to a local library, organize them with folders and tags, and inject them into the chat input with one click. Before you send, super powers can minify, optimize, A/B test, and more.

Supported sites

  • Claude (claude.ai)
  • ChatGPT (chat.openai.com and chatgpt.com)
  • Google Gemini (gemini.google.com)

Good fits

  • You reuse the same prompts across sessions or models.
  • You want better results without learning prompt engineering from scratch.
  • You need folders and tags to keep dozens or hundreds of prompts findable.

Install

  1. Install PowerPrompter from the Chrome Web Store (link on the product page when live).
  2. Pin the extension icon in Chrome’s toolbar for quick access.
  3. Open Claude, ChatGPT, or Gemini in a tab.
  4. Click the PowerPrompter icon to open the side panel.

PowerPrompter works without signing in on the Free plan. Sign in from Settings when you want cloud sync or a paid plan.

First use

  1. Open the side panel on a supported chat page.
  2. Click Create prompt and add a title and body.
  3. Select the prompt and click Inject to chat to paste it into the input field.
  4. Optional: choose a super power from the dropdown to refine the prompt before injecting.

On first launch, a short onboarding tour walks through save, organize, super powers, and upgrading.

Your prompt library

Create and edit

Each prompt has a title and body. Use {{variable}} placeholders in the body—PowerPrompter prompts you to fill them in before injection.

Folders

Organize prompts in folders up to three levels deep. Drag prompts between folders or create subfolders from the folder menu.

Tags

Add tags to prompts for cross-cutting categories. Tags autocomplete as you type and can be used to filter the list.

Search and sort

Search by title or body. Sort by recently updated, name (A–Z or Z–A), or most used. The list paginates when you have many prompts.

Favorites and export

Star prompts as favorites for quick access. Export your library as JSON (powerprompter.export.v1) from Settings, or import a backup from another browser.

Super powers

Super powers refine your prompt before you inject it. Select a power from the dropdown, adjust any options, and preview the result. Core powers run locally; Pro and Max AI powers use your own API key.

Free — core super powers

  • Minify — strip filler and verbose phrasing (lite / full / ultra levels).
  • Convert format — reshape into bullets, numbered steps, or Markdown sections.
  • Inject role — prepend an expert persona.
  • Set output format — specify how the answer should be structured.
  • Set tone — append a tone-of-voice directive.
  • Set language — request answers in a specific language.

Pro — AI super powers

Requires a Pro or Max subscription and your own API key (OpenAI-compatible, Anthropic, or Gemini). See how to set up an API key.

  • Optimize — rewrite for clarity and LLM effectiveness.
  • Explain — analyze strengths, weaknesses, and suggested fixes.
  • Expand context — add constraints and success criteria to terse prompts.
  • Token estimate — approximate token count and API cost.

Max — advanced super powers

  • Variants — generate Direct, chain-of-thought, and few-shot variants.
  • Specialize — add domain terminology and disclaimers.
  • A/B test — compare two prompt versions side-by-side, with optional AI analysis.

Inject and save from chat

Inject to chat

Select a prompt in the side panel and click Inject to chat. PowerPrompter finds the chat input on the active tab and inserts the prompt text. If the prompt has variables, a fill-in modal appears first.

Save from chat

On a supported chat page, type or paste text in the input, then click Save from chat in the side panel. PowerPrompter captures the current input as a new prompt.

Plans and limits

Feature Free Pro Max
Prompts stored 25 500 Unlimited
Signed-in devices — 2 3
Core super powers Yes Yes Yes
AI super powers — Yes Yes
Advanced super powers — — Yes
Cloud sync — Yes Yes

Upgrade from Settings in the extension. After checkout, return to PowerPrompter and click Refresh subscription status so your plan updates.

If you downgrade and exceed your prompt limit, the library becomes read-only—only the newest prompts within your limit stay editable until you delete prompts or upgrade.

Common issues

Inject does nothing

  • Make sure you are on a supported chat page (Claude, ChatGPT, or Gemini).
  • Refresh the tab and reopen the side panel.
  • Click inside the chat input first, then try Inject again.

Super power is locked

  • Core powers are free. AI and advanced powers require Pro or Max.
  • Sign in and confirm your subscription in Settings.
  • For AI powers, set up an API key in Settings (BYOK).

AI super power failed or invalid API key

  • Confirm you have a Pro or Max subscription and are signed in.
  • Open Settings → LLM provider and paste your key. Click Test connection.
  • Match the provider to your key format: OpenAI-compatible (sk-…), Anthropic (sk-ant-…), Gemini (AIza…).
  • If you see a 401 error, create a new key at your provider and try again. See Set up an API key.

Subscription not updating after payment

  1. Open PowerPrompter Settings.
  2. Click Refresh subscription status.
  3. Wait a minute and try again if it still shows the old plan.

Prompt limit reached

Free accounts can store 25 prompts. Delete unused prompts or upgrade to Pro (500) or Max (unlimited).

Read-only library after downgrade

Delete prompts until you are within your plan limit, or upgrade again. Only prompts within the limit remain editable.

Set up an API key

Pro and Max AI super powers (Optimize, Explain, Variants, A/B test analysis, and others) call the LLM provider you choose. PowerPrompter uses a bring your own key (BYOK) model—you create an API key with OpenAI, Anthropic, or Google and use it from Settings.

Some providers offer free API keys and free usage tiers (with daily or monthly limits). You only pay the provider if you exceed those limits or choose a paid-only plan—PowerPrompter never bills you for LLM API usage. Check each provider’s current pricing before you rely on a free tier.

In PowerPrompter

  1. Open the side panel and go to Settings.
  2. Under LLM provider (BYOK), choose the provider that matches your key.
  3. Paste your API key and click Test connection.
  4. Select a model from the dropdown (or enter a custom model if your provider requires it).

Keys are encrypted and stored locally in your browser. They are sent only to the provider you configure—never to PowerPrompter servers. See Privacy for details.

OpenAI-compatible

Use this for OpenAI API keys (usually starting with sk-). Advanced setups (Azure OpenAI, local proxies) also use this option with a custom base URL in developer builds.

  1. Sign in to your OpenAI account.
  2. Create an API key on the OpenAI platform.
  3. Copy the key and paste it into PowerPrompter Settings.
  4. In PowerPrompter, select OpenAI-compatible as the provider.

Open OpenAI API keys page (official provider site). OpenAI API access is typically pay-as-you-go; a payment method is usually required. Check OpenAI’s site for any trial credits or promotions.

Anthropic (Claude)

Anthropic Console keys usually start with sk-ant-.

  1. Sign in to the Anthropic Console.
  2. Create an API key under Settings → API keys.
  3. Copy the key and paste it into PowerPrompter Settings.
  4. In PowerPrompter, select Anthropic (Claude) as the provider.

Open Anthropic API keys page (official provider site). New accounts may include free trial credits—see Anthropic’s pricing page for current offers.

Google Gemini

Google AI Studio keys usually start with AIza.

  1. Sign in with your Google account.
  2. Create an API key in Google AI Studio.
  3. Copy the key and paste it into PowerPrompter Settings.
  4. In PowerPrompter, select Google Gemini as the provider.

Open Google AI Studio API keys page (official provider site). Google AI Studio offers a free tier with rate and usage limits— a good option to try AI super powers at no API cost.

Privacy

Prompts are stored locally in your browser by default. On Pro or Max, signed-in users can sync prompts to the cloud.

API keys for AI super powers are encrypted and stored locally. They are sent only to the provider you configure (OpenAI, Anthropic, Gemini)—never to PowerPrompter servers.

You can opt out of analytics in Settings. See KyberFlow Labs privacy policies for broader data handling.
