Of 777 spoken Korean sentences put through Papago in a study indexed by Korea's national citation database, 434 came back correct and 343 did not. That is a 44.1% error rate on speech, from the app that Korea guides routinely describe as the one that "just gets Korean." The difference between the two apps is real. It sits somewhere other than where the forums put it.
Install both. Papago is built Korean-first and translates offline in Korean, English, Japanese and Chinese. Google Translate covers nearly 250 languages, has no paid tier, and sets no monthly cap on photo or voice translation. In Korea, open Papago first for Korean text and switch to Google the moment a free quota runs out or the source language is not Korean.
Four things decide it in practice:
- Papago's free tier stops at 30 image translations a month. Google's camera mode has no published cap.
- Papago's offline packs cover four languages. Google's catalogue runs to nearly 250.
- No published benchmark scores both engines head-to-head on Korean to English. Anyone quoting a percentage gap is inventing it.
- Desktop web-page translation now favours Chrome. Papago moved that feature behind its paid app.
Who builds each app, and why that shapes what you get
Papago is a NAVER Corp. product, named after the Esperanto word for parrot, and it left its trial phase on 19 July 2017. The US App Store listing describes it as free with advertising and lists 14 languages, including Korean, English, Japanese, both Chinese scripts, Vietnamese, Thai, Indonesian and Arabic. Encyclopedia entries list 16, adding Portuguese and Hindi. NAVER has not reconciled the two counts in one public place, so treat 14 as the floor.
Google Translate turned 20 in 2026. In a company blog post dated 28 April 2026, Rose Yao, VP of Product for Search, put the service at nearly 250 languages, more than 60,000 language pairs, over a billion monthly users and about a trillion words translated per month, reaching roughly 95% of the world's population. The same post names English to Spanish as the top pair and "Thank you" as the most-translated phrase.
That contrast is the whole story. Korean is one of 250 languages for Google and it is the entire product for Papago. It explains why Papago's interface assumes Hangul input, why its handwriting pad exists, and why its offline packs stop at Korea's four most relevant languages. It does not, by itself, prove better Korean output.
Papago vs Google Translate: the feature table
This table answers one question: which app can actually do the thing you need, for free, while standing in a Seoul restaurant. Figures checked 14 August 2026.
| Feature (Aug 2026) | Papago | Google Translate | Edge |
|---|---|---|---|
| Languages | 14 listed (16 per encyclopedias) | Nearly 250 | |
| Offline Korean | Yes, 4 languages only | Yes, downloadable pack | Tie |
| Photo translations, free | 30 per month | No published cap | |
| Voice translation, free | 30 minutes per month | No published cap | |
| Document translations, free | 20 per month | Via Docs and Drive | Papago |
| Consumer paid tier | ₩13,000–₩75,000/month | None | |
| Desktop web pages | Requires Papago Plus | Built into Chrome |
On mechanics alone Google takes most rows, and that is the honest reading of the published limits. Papago's case rests on Korean-specific behaviour that no public benchmark has scored, plus an interface designed around Hangul rather than adapted to it. Papago's offline pack, added in the 5 November 2019 update, covers Korean, English, Japanese and Simplified Chinese and nothing else, which matters on a KTX carriage or in a basement restaurant with no signal.
The web-translation story is worth knowing before you sit down with a laptop. From September 2024 NAVER moved Papago's web-page translation into its mobile apps and the Naver Whale browser, launching Papago Plus in the same month; a desktop button returned in 2025 but requires the Papago Plus app. Chrome translates a Korean page in one click with nothing installed.
What the accuracy research shows, and what it does not
There is no published Korean-to-English benchmark scoring both engines with BLEU or COMET on the same corpus. That absence is the single most useful fact in this comparison, because the confident claims circulating online have nothing underneath them.
What does exist points three ways. The spoken-Korean study above put Papago at 55.9% correct across 777 sentences. A separate Korean study using dialogue from the novel Pachinko scored ChatGPT at 343 correct out of 590 (58.1%) against Papago's 223 out of 590 (37.8%), which says more about literary dialogue than about either app's handling of a menu. A third study, on Korean interview interpretation, found accuracy for Google Translate and Papago high in word-choice syntax and concluded that the two machine translators perform almost the same.
So the defensible position is narrow: on ordinary written Korean the two are close, both fall apart on spontaneous speech, and Papago's genuine advantages are product features rather than a proven quality gap.
One change could move this. In a post dated 12 December 2025, Google began rolling Gemini-powered text translation into Translate for users in the US and India, covering English paired with nearly 20 languages, alongside a live speech-to-speech beta on Android in the US, Mexico and India spanning over 70 languages. Korean is not named in that language list, and Google has not said whether it is included. If Korean lands in the Gemini tier, the folk wisdom about Papago's edge needs re-testing.
When Papago's free tier runs out: the arithmetic
The Papago Plus pricing page sets the free allowance at 30 image translations a month, 20 document translations, 30 minutes of voice and one glossary of 10 terms, with limited text translation. Paid tiers, VAT included as of 14 August 2026, run ₩13,000 a month for Plus Basic, ₩40,000 per member for Standard, and ₩75,000 per member for Advanced, which raises the ceiling to 1,000 images and 150 documents a month.
Run a normal trip through those numbers. Six days in Seoul, seven photographed items a day between menus, ingredient labels and shop signs, is 42 image translations. The free 30 are gone partway through day five (30 ÷ 7 = 4.3 days), leaving 12 photos short.
Buying Plus Basic to cover those 12 costs ₩13,000, which at the 14 August 2026 USD/KRW rate of 1,416.50 is about US$9.18. That works out to ₩1,083 per remaining photograph. Google Translate's camera mode does the same 12 for nothing, with no tier to buy.
Verdict: for any trip shorter than a month, do not pay. Use Papago until it stops, then finish the trip on Google. Plus Basic starts making sense for residents doing sustained document work, and Advanced only for someone handling volume in the hundreds of files, which is a business expense rather than a travel one. At ₩75,000 a month, Advanced is about US$53 at the same rate.
If you are calling these as APIs rather than tapping an app
Papago's free developer API ended on 29 February 2024 and the service moved to NAVER Cloud Platform as a paid product. Per the NAVER Cloud API guide, text translation supports 29 language pairs, document and website translation 15, and language detection 15 languages, with a ceiling of 300,000 characters and 100 MB per document. Billing counts requested characters in units of one million. NAVER does not surface the won-per-million figure on the guide pages, so the number comes from the console quote.
Google publishes its Cloud Translation price list openly. Third-party pricing trackers put it at about US$20 per million characters for both the Basic and Advanced editions with the first 500,000 characters each month free, and the Translation LLM tier at $10 per million in and $10 per million out. Those figures come from trackers rather than Google's own page, so treat them as indicative of the order of magnitude, not as a quote.
Where both apps fail
Spontaneous speech is the shared weak point, and it is the one situation travellers most want to trust. The 44.1% error rate cited above was measured on spoken Korean, not written. Conversation mode works far better if the speaker delivers one short declarative sentence and stops.
Honorifics vanish in both directions. Korean marks politeness grammatically and English does not, so a reply that was blunt in Korean arrives in English sounding neutral. Nothing in either app warns you that the sentence you just sent reads as curt.
Dish names are the second trap. Korean food words are frequently proper nouns, and machine output literalises them, which turns a specific dish into a vague description of its main ingredient. For allergies, neither app is a safe single source; carry the Korean word for the allergen written out and show the text itself.
Handwritten and low-contrast signage defeats camera OCR in both apps. Typing the Hangul, or drawing it with the handwriting input, gets a result when the photo will not.
Finally, neither output is a certified translation. Offices that require one for immigration, court or academic filings will not accept an app screenshot, whichever app produced it. This article is general information about two consumer products; prices and tier limits carry the date they were checked and change without notice.
FAQ
Is Papago better than Google Translate for Korean?
There is no published benchmark scoring both engines on the same Korean dataset, so the claim cannot be verified. The one Korean study that assessed both on interview interpretation concluded their accuracy is almost the same. Papago's advantages are concrete but structural: Korean-first interface, handwriting input, and offline packs weighted to Korea.
Does Papago work offline?
Yes, since the 5 November 2019 update, and only for Korean, English, Japanese and Simplified Chinese. Download the pack on Wi-Fi before you land, because the underground stretches of the Seoul network are where you will want it.
Is Papago free?
The app is free with advertising. The free tier allows 30 image translations, 20 document translations and 30 minutes of voice per month; Papago Plus starts at ₩13,000 a month as of 14 August 2026.
Does Google Translate work in Korea?
Yes, fully. The Korean restriction people remember applies to Google Maps driving directions, which is a map-data issue and unrelated to translation. For getting around, a Korean mapping app is the better tool anyway; see Naver Map vs Kakao Map.
Do I need a translation app for subway signs?
Rarely. Seoul, Incheon and Gyeonggi station signage and announcements already run in Korean, English, Japanese and Chinese. The apps earn their keep on menus, ingredient labels, pharmacy boxes and handwritten notices.
Can either app replace learning Hangul?
No, and the alphabet is a weekend of study rather than a project. Once you can sound out a sign, you stop photographing half of them. Free official study material is listed in our guide to Korean for beginners PDFs.
