Do I need a ClipHistory account or subscription to use custom AI prompts?

No. ClipHistory is 100% local with no cloud or account. You pay $19.99 once for a lifetime license and bring your own API key from OpenAI, Anthropic, DeepSeek, Google, or a custom endpoint. No recurring fees ever.

Can I store multiple custom prompts and reuse them across my clipboard history?

Yes. Create as many custom prompts as you need—each one is a template you apply to any clip. With ⌘⇧V open, select a clip and choose your prompt. ClipHistory saves all 150 unpinned clips plus unlimited pinned ones for easy access.

Will my clipboard history and API keys be synced to the cloud or stored on ClipHistory's servers?

No. Everything stays on your Mac. Your clipboard history, custom prompts, and API keys are 100% local. ClipHistory sends text only to the AI provider you explicitly choose—never to ClipHistory servers.

Which AI providers can I use with custom prompts in ClipHistory?

ClipHistory supports five providers: Anthropic (Claude), OpenAI, DeepSeek, Google Gemini, and custom endpoints. You control which one to use per prompt and bring your own API key for full privacy and cost control.

How to Create Custom AI Prompts for Clipboard Transform on Mac

Your clipboard holds fragments of information throughout the day—email drafts, code snippets, research notes, meeting transcripts. Transforming them manually takes time. But what if your clipboard manager could intelligently rewrite, summarize, or translate any clip on demand using custom AI prompts tailored to your workflow?

ClipHistory, a lightweight macOS clipboard manager, makes this possible. With support for five AI providers and the ability to define custom prompts, you can shape how your clipboard content is processed without relying on cloud services or subscriptions.

Why Custom AI Prompts Matter for Mac Users

Most clipboard managers on macOS—like Paste or Maccy—store and retrieve clips. ClipHistory goes further. When you press ⌘⇧V to open your clipboard history, you can instantly apply transformations powered by AI. Instead of copying text, pasting it into ChatGPT, waiting for a response, and copying back, you define the exact instruction once and reuse it forever.

Custom prompts let you:

Enforce consistency: "Rewrite this in our brand voice"
Extract actionable data: "Pull out all dates and deadlines"
Save repetitive work: "Summarize in three bullet points"
Localize content: "Translate to Spanish (formal tone)"

For developers, writers, analysts, and support teams, this reduces context-switching and speeds up routine text tasks by 50–70%.

How ClipHistory Custom AI Prompts Work

ClipHistory stores your full clipboard history—up to 150 unpinned clips plus unlimited pinned ones. It auto-detects clip type (URL, email, code, color, phone, image) and makes each one transformable.

When you create a custom prompt, you're defining a reusable instruction that ClipHistory sends to your chosen AI provider. Here's the workflow:

Save a clip via normal Mac copy (⌘C)
Open ClipHistory with ⌘⇧V
Select the clip you want to transform
Choose a custom prompt from your library
ClipHistory sends it to your AI provider (Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint)
Result appears instantly — paste the output or save it as a new clip

Setting Up Your First Custom Prompt

Because ClipHistory is 100% local and stores nothing in the cloud, you control the entire pipeline. You bring your own API key—whether that's OpenAI, Anthropic's Claude, DeepSeek, Google Gemini, or your own custom endpoint.

Example 1: Email Reply Helper

Prompt Name: "Draft Professional Reply"
Instruction: "Take this incoming message and draft a brief, professional response acknowledging the request and next steps."
Provider: OpenAI (or your preference)
Your API Key: Stored locally on your Mac

Example 2: Code Cleaner

Prompt Name: "Format & Comment Code"
Instruction: "Clean up this code: fix formatting, add clear comments, remove unused variables, suggest one optimization."
Provider: Anthropic (Claude)

Example 3: Content Translator

Prompt Name: "Translate to French"
Instruction: "Translate the following text to French (formal register), preserving all formatting and line breaks."
Provider: Google Gemini

Each prompt is a template. Once defined, you never re-type the instruction—just select the clip and apply the prompt.

Bring Your Own AI Keys (No Subscriptions)

A key difference between ClipHistory and cloud-dependent tools: you're not locked into ClipHistory's pricing or limits. You manage your own relationship with AI providers.

Have a free tier with OpenAI? Use that. Already paying for an Anthropic subscription? Plug in your key. Want to route everything through a custom endpoint or local LLM? ClipHistory supports that too.

You pay only for the API calls you make—often a few cents per month for typical clipboard transforms. No recurring fees, no forced upgrades.

Security & Privacy Considerations

Because ClipHistory runs locally on your Mac with no cloud sync or user accounts:

Your API keys never leave your machine
Your clipboard history never touches external servers (except the AI provider you explicitly choose)
No account creation, no email, no tracking
Signed and notarized by Apple—proof of integrity

This is crucial for teams handling sensitive data, passwords, or proprietary code. Your clipboard is yours alone.

Real-World Workflow Examples

For Writers & Content Teams: Pin a lengthy first draft → apply "Summarize in 100 words" → compare with original → iterate. No tab-switching.

For Developers: Copy a stack trace → apply "Explain this error and suggest fixes" → read the explanation inline → fix faster.

For Support & CS: Paste customer message → apply "Categorize as bug/feature/question and draft response" → batch replies in 10 minutes instead of 30.

For Researchers: Collect quotes from articles → apply "Extract key findings and cite source" → build a structured reference doc.

Alternatives on macOS

Competitors like Paste, Raycast, and Alfred offer clipboard management and some automation, but they either require subscriptions (Paste), don't focus on clipboard history (Alfred, Raycast), or lack flexible AI transform with custom prompts. ClipHistory's lifetime $19.99 license and local-first design make it uniquely lightweight for this specific use case.

Next Steps

If you're manually transforming clipboard text multiple times per week, custom AI prompts will save hours. ClipHistory makes this frictionless on macOS—just press ⌘⇧V, pick your prompt, and get results.
