Swiftin vs Immersive Translate

Both tools translate pages side by side, that part is a tie. The difference is what powers it. Swiftin Free includes 50,000 AI tokens a month across four AI model families, plus unlimited Google and Bing translation that takes over automatically when the quota is spent, so a page never stops mid-translation. Immersive Translate's free tier runs its general translation models under fair-use daily caps; its stronger AI models sit on the Pro and Max plans, or behind your own API key.

Immersive Translate's input translation is a quick swap: press space three times and your draft is replaced. Swiftin treats writing as a first-class surface: a translate button lives in any input field, chat, email, social, forms, and Pro adds three tone styles, Normal, Business and Slang, so a reply to a client and a reply in a game chat come out sounding different. You type in your language and send in theirs, without leaving the field.

Immersive Translate splits its offer into Pro at $14.99 and Max at $39.99 a month, each with separate buckets: top-tier model tokens, advanced model tokens, PDF pages, comic images, subtitle minutes. Its 3-day trial is attached to the annual plan and renews at the full year price after the trial. Swiftin has one Pro plan at $6.99 a month with a single AI token pool, and the free Google and Bing engines stay unlimited on every plan.

Swiftin ships AI text-to-speech in 70+ languages: select a sentence or a translated paragraph and hear it spoken, which turns reading practice into listening practice and helps when you can read a language better than you hear it. Immersive Translate does not offer AI voiceover for translations.

Swiftin only charges tokens for translations that actually succeed. A provider error, a same-language page, a repeated request served from cache: none of it touches your quota. Translation history is off by default and strictly opt-in, so nothing is stored unless you turn it on. Simple rules you can hold us to.
