About Denys Kandyba

Founder of SwiftIn. I built the tool I wished existed when I was trying to work across languages.

Why SwiftIn exists

A few years ago I was spending half my day copy-pasting messages into Google Translate — replying to clients on Upwork, chatting with teammates on Slack, messaging friends on Discord, reading threads on Reddit. It worked, but it was ugly. Every conversation was two tabs and a tab switch every thirty seconds, and none of the translations actually sounded like me.

SwiftIn is the tool I wished existed back then. You type where you're already typing, it translates as you go in the style you pick (casual, formal, or neutral), it reads the result aloud if you want to double-check how it sounds, and it never asks you to leave the page. No copy-paste, no tab switching, no robotic translations that make you sound like a tourist phrasebook.

How I build SwiftIn

  • One voice, no committee. I make every product decision, shape the features I'd use myself, and ship weekly.
  • Transparent pricing. Every number on the pricing page is the real number — not a “starting at” teaser. Yearly billing saves 20%, crypto is VAT-free, and every plan lists exactly how many characters you get per month.
  • Your data isn't the product. No ads, no reselling, no training models on your translations. Payments go through Paddle (cards) or NOWPayments (crypto). Product analytics via PostHog, which you can opt out of in one click.
  • I ship features I actually use. Input translation, chat auto-translate on 8 platforms, AI text-to-speech, text selection — all of them started because I needed them, not because a roadmap spreadsheet said to.
  • Support is me. When you email support@swiftin.dev, I read the email. There's no tier-one queue to escape.
