Hi! Before we release your payment, could you send your invoice details — company name, GSTIN and bank account?
Pay with card
A live demo.
The everyday hunt
And every answer starts with digging — through a Notion doc, an old email, a photo of a card.
Hey! What’s your portfolio link?

Dozens of times a day, every day. OnePaste makes it one double‑tap.
How it works
No shortcuts to learn, no abbreviations to remember. If you can find it, you can paste it.
Add your links and details — or import them from your website, your Contacts card or a list in seconds.
Mail, Slack, a form in Chrome — OnePaste opens right next to your text cursor.
Could you send me your calendar link?
cal.com/yourname
Type two letters, press Return. Your clipboard stays exactly how you left it.
Designed for Mac
Every detail is built so you never break your flow — or your privacy.
Here’s my portfolio: yourname.com/work
Like native autocomplete — the overlay appears at your text cursor, and the paste lands exactly there.
Type “ig” for Instagram or “cvv” for your card. Aliases and smart ranking built in.
Hold ⌥ to peek
PAN, Aadhaar and card numbers stay hidden until you hold ⌥.
Checkout wants the number, then the expiry, then the CVV. Keep them together and paste each part where it goes.
Pasting your PAN on a call? The overlay stays on your screen only — it’s left out of screen shares and recordings.
OnePaste borrows it for a blink, then puts back what you’d copied.
Native apps, every browser, Slack, Notion and Figma — without stealing focus.
Point it at your portfolio or link-in-bio page — Linktree, Zaap, Bento — or your Contacts card. Your profiles move in.
Your details live on your Mac — not on our servers, not in someone’s cloud. The sensitive ones stay masked, even from clipboard managers and screen shares.

Why it exists
“I was answering the same questions a thousand times a day — my portfolio, my PAN, my calendar link. Every answer meant digging through a Notion doc. So I built the thing I wanted: double-tap, pick, done.”Kailash Saravanan, product designer and maker of OnePaste · Read the story

Requires macOS 14 Sonoma or later on Apple silicon.
OnePaste is a native Mac app for the things people keep asking you for — your portfolio and social links, calendar link, email, phone, address, PAN or Aadhaar, UPI and card details. Save them once, then double-tap the Option key in any app, pick one from a small overlay at your cursor, and it’s pasted where you were typing.
Text expanders replace abbreviations you type, so you have to remember every shortcut. OnePaste is visual: double-tap Option, type a few letters to search, press Return. There’s nothing to memorize, which makes it ideal for the dozens of links and details you share all the time.
Clipboard managers keep a history of everything you copied, so the thing you need has to be copied first and found among everything else. OnePaste is a small, curated library of the answers you give all the time — always there, masked when sensitive, and opened right at your cursor. Many people happily use both.
Yes. It works anywhere you can type on your Mac — native apps, browsers like Chrome, Safari and Arc, and Electron apps like Slack, Notion and Figma. The overlay never takes keyboard focus away from the field you’re typing in, so the paste lands exactly where your cursor is.
Everything stays on your Mac in a local file — there’s no account, no cloud and no tracking. Sensitive items like PAN, Aadhaar and card numbers are masked in the overlay, hidden from clipboard managers when copied, and wiped from the clipboard after a minute.
The OnePaste overlay is excluded from screen sharing and recordings using macOS’s window-sharing setting, so you can paste details during a call without broadcasting them.
A Mac with Apple silicon running macOS 14 Sonoma or later. OnePaste asks for Accessibility access once, so it can notice your double-tap and paste into other apps.
Yes — Smart Fill. Double-tap in any field of a form and OnePaste shows every field it recognises — name, email, phone, links, address, PAN, GSTIN, card number, expiry, CVV — with the answer it will use. Press Return and they’re all filled. It never fills password or hidden fields and never submits for you. Safari and Mac apps work straight away; Chrome, Edge, Brave and Arc need one setting.
No. It’s a one-time purchase of $19: pay once and it’s yours, with a 14-day money-back guarantee.
Everything you get asked for, one double‑tap away.
