Can I sync my clipboard history across my Mac and iPad?

ClipHistory is macOS only and stores everything locally on your Mac. No iPad or cloud sync. If you need multi-device sync, this isn't the tool. If you want fast, private, single-machine clipboard management, ClipHistory is perfect.

How many formulas and equations can I store?

ClipHistory keeps your 150 most recent unpinned clips automatically, plus unlimited pinned items. Pin your essential formulas—stress equations, unit conversions, regex patterns—and they stay forever. That's 150 + ∞ slots.

Do I need an API key or account to use ClipHistory?

No. ClipHistory works completely offline with no account. If you want AI transforms (rewrite, summarize, clean), you bring your own API key to Anthropic, OpenAI, DeepSeek, or Google. Full control, zero forced cloud.

Is this a subscription? Can I use it forever after paying once?

Yes. $19.99 is a one-time lifetime license. Not a subscription. Not recurring. You own it on your Mac forever, with free updates. No cloud account required. Press ⌘⇧V and paste—that's it.

How Engineers Save Calculation Formulas to Clipboard on Mac: The Smart Way

As an engineer, your clipboard is a working tool. You paste formulas, equations, unit conversions, and code snippets dozens of times per day. But macOS clipboard only holds one item at a time—once you copy something new, yesterday's formula is gone forever.

That's where a clipboard manager changes your workflow.

Why Engineers Need a Clipboard Manager

When you're deep in calculations—stress testing load factors, converting between unit systems, or referencing dimensional analysis formulas—context switching is costly. Every time you leave your calculation tool to hunt down a formula you copied earlier, you lose focus.

A clipboard manager lets you:

Keep every formula you've ever copied so you never re-derive the same equation
Search instantly by formula name, variable, or context
Auto-organize by type so calculations stay separate from URLs and emails
Paste with one keystroke and get back to work

ClipHistory: Built for Engineers on Mac

ClipHistory is a lightweight macOS clipboard manager designed exactly for this workflow. Press ⌘⇧V, search your clipboard history, and paste. That's it.

Store Everything, Forget Nothing

ClipHistory keeps 150 unpinned clips in your history, plus unlimited pinned items. Pin your most-used formulas—structural load equations, thermodynamic constants, conversion factors—and they stay at your fingertips forever. No subscription. No cloud. No account. Everything stays on your Mac.

Auto-Detect Every Clip Type

Engineers work with mixed data types: code snippets, mathematical notation, CSV data, hex color codes, phone numbers for suppliers, URLs to documentation. ClipHistory auto-detects what you've copied—whether it's code, a formula, an email, or a color value—so you can filter and find items faster than scrolling.

AI Transform Your Formulas

Sometimes a formula needs cleanup. Maybe you copied a messy calculation from a PDF, or you need to convert a formula from one notation to another. ClipHistory's AI Transforms let you:

Rewrite a formula in cleaner notation
Translate between notational systems
Summarize complex multi-line equations
Clean OCR artifacts from scanned PDFs

Choose from 5 AI providers: Anthropic, OpenAI, DeepSeek, Google, or bring your own API key. You control which service processes your data.

100% Local, No Cloud

Your clipboard is private. ClipHistory runs entirely on your machine—no cloud upload, no sync to Slack, no telemetry. Your calculation history never leaves your Mac.

Real Engineering Workflows

Structural Engineer: Pin AISC steel design formulas (moment of inertia, shear stress, deflection limits) in a custom board. When a new project starts, open ClipHistory, search "deflection," and paste—no hunting through notebooks or retyping.

Data Scientist: Copy experiment parameters, loss function formulas, or data transformation snippets. ClipHistory keeps 150 items in history. When you want to compare two approaches, search "batch_norm" and find both versions instantly.

Software Engineer: Paste regex patterns, curl commands, SQL queries. Use AI Transform to rewrite a regex for readability, or clean a formula pasted from Stack Overflow.

Product Designer: Store color hex codes, spacing ratios, typography scales. Search "primary" and access every shade you've ever used, pinned to a board.

Why Not Alternatives?

Competitors offer different tradeoffs:

Paste and Pastebot are powerful but subscription-based ($30–50/year recurring).
Maccy is free but minimal—no AI, no pinning, no custom boards.
Alfred is a launcher with clipboard history as a side feature, not the focus.
Raycast requires a plugin ecosystem and account.

ClipHistory combines pinned unlimited storage, AI transforms with your own API keys, custom boards for organizing formulas, one-time $19.99 lifetime license, and zero account friction. You own it. It's signed and notarized. Works on any Mac.

Getting Started in 60 Seconds

Copy a formula, equation, or code snippet (like you normally do).
Press �CMD⇧V to open ClipHistory.
Search, pin, or transform it.
Paste with one click or arrow key.

That's the entire interface. No learning curve. No configuration required (unless you want to bring your own AI key).

Perfect for Teams of One (or Many)

If you're a solo engineer or researcher, ClipHistory eliminates clipboard friction. If you're on a team, each member runs it locally on their Mac—everyone benefits from 100% privacy, no shared cloud account, no sync delays.

Invest Once, Use Forever

At $19.99, ClipHistory is a one-time purchase. No recurring subscription. No upgrade nags. No feature gating behind a paywall. You get lifetime updates and access to all transforms (using your own AI keys).

Compare that to annual clipboard manager subscriptions that add up to $150+ over five years. Or compare to the time you spend re-deriving formulas you copied last month but lost.

Get ClipHistory — $19.99 and reclaim the 10+ minutes per week engineers waste looking for copied formulas.

macOS only. Universal binary. Signed and notarized. Works on any Mac.
