AI Clipboard Assistant to Rewrite & Translate Mac

An AI Clipboard Assistant to Rewrite and Translate on Mac

Most clipboard managers do one thing: they remember what you copied. That is useful, but it leaves the actual work — rewriting, translating, cleaning up, summarizing — to you and a pile of other apps. ClipHistory adds an AI layer directly to the clipboard, so the text you just copied can be transformed before you paste it.

This post walks through what an AI clipboard assistant actually does, how ClipHistory implements it, and where it fits in a real workday.

What "AI clipboard assistant" means here

It is not a chatbot bolted onto a copy buffer. It is a focused set of transforms you can run on any clip:

Each one operates on a clip in your history and produces a new clip with the result. You trigger them from the ClipHistory window, which you open with Cmd+Shift+V.

The architecture that matters: your key, your provider, local data

The single most important design decision in ClipHistory is that it is bring-your-own-key. You connect one of five providers — Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint — and AI requests go straight from your Mac to that provider.

What this means in practice:

For people who copy sensitive material — code, contracts, customer data — the local-first model is the difference between a tool you can use at work and one you cannot.

A day with the assistant

Here is how the transforms stack up in normal use.

Morning: triage

A long email thread lands in your inbox. Copy it, hit Cmd+Shift+V, run Summarize. You get the gist in a few bullets without reading every reply. Pin the summary if you will reference it in a meeting later — pinned clips are unlimited and never roll off.

Midday: writing

You draft a reply but it is rough. Copy it, Rewrite for grammar and tone, paste it back. If the recipient speaks another language, chain Translate after the rewrite so the final text reads naturally in their language.

Afternoon: cleanup

You are assembling a document from a dozen sources. Each paste brings formatting baggage. Run Clean on each clip, queue them in the paste stack, and drop them in order. The document stays consistent because every fragment was normalized first.

Boards and snippets: organizing what the AI produces

Transforms create clips; boards organize them. A board is a named collection where you can group related clips — for instance, all the translated strings for one project, or every summary from one research session.

For text you reuse verbatim, snippets are the right home. A snippet does not need an AI call; it is a saved block you paste instantly. The practical split: use AI transforms for fresh, one-off text, and snippets for boilerplate you produce once and reuse forever.

How it compares to copying into a chatbot

You could paste into a chatbot app for each of these tasks. The friction adds up: switch apps, paste, wait, copy the answer, switch back, paste again. And your clipboard history is somewhere else entirely.

ClipHistory keeps the whole loop in one place. The text is already in your history, the transform is one menu away, and the result lands back in the same history ready to paste. No app-switching tax, and your 150 recent clips (plus unlimited pinned ones) are all searchable.
