Editor's note: This piece is part of a series in which we open up and examine AI apps and services making waves in South Korea. This instalment looks at Papago, Naver's translation service.

In January 2024, Naver disclosed that Papago had roughly 18.9m global monthly active users (MAU) across its app and web platforms combined, of whom some 5.1m were based outside South Korea. The figures underscore a broader shift: translation apps have evolved from emergency aids for the linguistically challenged into standard tools for international travel and business. In an era when ChatGPT and Gemini translate as a matter of course, the question is how far Papago has kept pace.

What It Is

Papago is Naver's neural-machine-translation service. It offers text, voice, conversation, image, document and website translation within a single app. According to data Naver released in June 2023, the service then supported 15 languages: Korean, English, Japanese, Simplified and Traditional Chinese, Spanish, French, German, Russian, Portuguese, Italian, Vietnamese, Thai, Indonesian and Hindi. Arabic was added in February 2024, bringing the total to 16.

The business model layers a paid subscription tier—Papago Plus—on top of a free core service. Launched by Naver Cloud in September 2024, Papago Plus targets workplace users with features such as document and image translation and shared team glossaries. In February this year, the Electronic Times reported that the Papago team had returned to Naver's parent company from Naver Cloud after three years.

Core Features

The first is image translation. Two modes stand out: "instant image translation", which translates text captured in a photograph, and "AR real-time translation", which overlays translated text directly onto a live camera feed without requiring a separate shot. Naver says it employs HTS technology to parse sentence structure, alongside inpainting to render translated text at the original font size and position. In July this year, the feature gained an "AI briefing" layer: point the camera at Japanese product packaging and a summary appears; aim it at a Japanese shop sign and location data surfaces via a tie-up with Tabelog, the Japanese restaurant-review platform.

The second is workplace functionality. At launch, Papago Plus supported most common document formats—PDF, HWP, PPTX, DOCX and XLSX—including translation of embedded images, tables and formatting. Last September brought real-time voice translation via the app's microphone; in December that capability extended to a Chrome browser extension, displaying foreign-language video audio as Korean subtitles. English, Chinese and Japanese are currently supported.

The third is a study mode. Papago Edu, introduced in 2021, lets users photograph a passage of text and receive a translation alongside key vocabulary. A word-list function for consolidating and reviewing those terms was added in February 2023.

Strengths and Weaknesses

Papago's chief strength is its reach beyond the act of translation itself. Handling images, voice and documents within one app, and linking image translation directly into information search, creates a coherent workflow rather than a series of separate steps. A Naver spokesperson described the goal not as selling AI as a product but as embedding it invisibly within services, framing the Tabelog integration as "the beginning of service convergence". The growing share of overseas users also challenges the perception that Papago is primarily a Korean-language tool.

The weaknesses are equally clear. First, as features multiply, the boundary between free and paid tiers grows harder to navigate. At launch, Papago Plus was priced at ₩13,000 a month for the Basic plan, ₩40,000 for Standard and ₩75,000 for Advanced. Those rates are a stretch for individual users and invite direct comparison with global rivals such as DeepL for corporate buyers. Second, real-time voice translation remains limited to just three languages: English, Chinese and Japanese. Third, in September 2024 Naver shut down its PC web-page translation service, citing difficulty in delivering accurate, stable translations in that environment; it pointed users towards the Whale browser, the Papago app and the Naver app as alternatives.

Verdict

Papago is broadening its identity as a translator into that of a travel assistant and workplace tool, without abandoning its translation core. For travellers, image translation and AI briefings make a compelling case; for professionals, document translation and live voice interpretation are the draws. Even so, as general-purpose generative AI treats translation as table stakes, Papago must keep making the argument for why it specifically is worth reaching for.

★★★★☆ (4.0/5.0)

In a word

"From translation app to travel assistant—Papago's next contest is the step that comes after the translated word."
