Pastery is a native macOS clipboard manager that turns everything you copy into a visualized timeline. Instead of a plain text list of clipboard history, every item becomes a rich visual card โ€” image and screenshot thumbnails, link previews, color swatches, code blocks, and formatted text โ€” so you can scan and recognize what you copied at a glance.

What makes Pastery stand out is the experience and the depth of features baked in. It's built natively in Swift (no Electron, no web wrapper), so it feels like a first-party Apple app: fast, fluid, and right at home on macOS, with system materials, smooth animations, light and dark mode, and a polished Overview Mode that gives you a full-screen, searchable grid of your entire clipboard timeline.

The headline feature is visual search. Using Apple's on-device Vision framework, Pastery lets you find screenshots and images by the text and context inside them โ€” so a screenshot you copied last week is searchable, not lost. Combine it with powerful filters to narrow your clipboard history by type, app, or date and jump to the exact paste you need in seconds.

Pastery is also a productivity toolkit. Transform text before you paste โ€” change case, format and prettify JSON, clean up spacing and line breaks, and more in one click. Pin and organize frequent snippets, browse a clear chronological timeline, and keep your workflow moving without leaving the keyboard.

Everything runs locally and privately on your Mac. Your clipboard never leaves your device โ€” no cloud, no tracking, no account required. A genuinely native, visual, and private clipboard manager and clipboard history app for macOS.

Questions & Answers

As answered by people managing ForthWrite and Pastery app.

Which are the primary technologies used for building your product?

ForthWrite's answer

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

Pastery app's answer:

Pastery is built entirely with native Apple technologies: Swift and SwiftUI (with AppKit where needed), Apple's on-device Vision framework for image and screenshot search, and GRDB/SQLite for fast local storage. There's no Electron and no web wrapper. It runs on macOS 13+ and is universal for Apple Silicon and Intel.

What makes your product unique?

ForthWrite's answer

ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.

Pastery app's answer:

Pastery turns your clipboard into a visualized timeline instead of a plain text list. Every item you copy becomes a visual card โ€” image and screenshot thumbnails, link previews, color swatches, and code blocks โ€” so you recognize what you copied at a glance. Its standout feature is visual search: using Apple's on-device Vision framework, Pastery lets you find screenshots and images by the text and context inside them, so nothing gets lost in your history. It's all wrapped in a fast, polished, genuinely native macOS experience.

Why should a person choose your product over its competitors?

ForthWrite's answer

Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.

Pastery app's answer:

Most clipboard managers are either bare text lists or slow Electron apps. Pastery is built natively in Swift, so it's fast, lightweight, and feels like a first-party Apple app โ€” with system materials, smooth animations, and light/dark mode. Beyond standard clipboard history, it adds a visual timeline, on-device visual search for screenshots and images, filters by type/app/date, a full-screen Overview Mode, and one-click text transforms (change case, format JSON, fix spacing). Everything runs locally and privately โ€” no cloud, no account, no tracking โ€” and there's a one-time lifetime option, not just a subscription.

How would you describe the primary audience of your product?

ForthWrite's answer

Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.

Pastery app's answer:

Mac power users who copy and paste all day โ€” developers, designers, writers, researchers, and support teams. It's especially useful for people who work with lots of screenshots, links, snippets, and reference material and need to find something they copied earlier without digging through a plain history list.

What's the story behind your product?

ForthWrite's answer

Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.

Pastery app's answer:

Pastery started as a solo, indie project out of frustration with existing clipboard managers: they were either ugly text lists or heavy, slow Electron apps that didn't feel native on macOS. The goal was a clipboard manager that's genuinely native, visual, and private โ€” one that treats screenshots and images as first-class items you can actually search, and that feels indistinguishable from an app Apple would ship.

Who are some of the biggest customers of your product?

Pastery app's answer:

Independent Mac users and developers in the macOS productivity community

    I built ForthWrite to fix generic AI email, and I still use it every day

    I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest endorsement I can give.

    The Chrome extension lives inside Gmail and Outlook on the web. Open a thread, hit Alt+Shift+D, and a draft comes back in your voice, not a template. The free tier is real: 10 drafts per week, no API key, no credit card. Voice matching is included on free, because that is the point.

    What keeps it useful compared to Gemini or a chat tab: it learns from what you actually send. Every edit you make before hitting send becomes a signal. Over time the drafts drift closer to how you really write, and the dashboard shows the improvement curve so you can see it happening.

    The web compose surface lets you draft from forthwrite.ai without installing anything, useful for people who want to try before committing to the extension.

    Standard adds recipient-aware and intent-aware drafting plus AI coaching. Pro adds auto-draft (replies waiting when you open Gmail), batch replies, and Prompt Lab for version-controlling your prompts. Teams adds a shared persona and seat-level analytics.

    ForthWrite is not for everyone. If you just need quick replies and tone does not matter, Gemini is free and already in your inbox. ForthWrite is for people where tone does matter: client communication, relationship-driven threads, external correspondence where sounding off costs something real.

    Disclosure: I am the founder and use it daily. Happy to answer questions in the comments.
