Korean (한국어) is a full-coverage language on Free.ai. Every public tool accepts Korean: AI chat at /chat/, translation at /translate/, audio transcription at /transcribe/ko/, text-to-speech at /voice/ko/, writing tools at /write/blog/ and /write/email/, image generation at /image/generate/ (prompts in Korean work but English prompts produce best results), and code generation at /code/. Currently active surfaces: chat, search, assistant, write, summarize, paraphrase, grammar, humanizer, detect-ai, expand, simplify, rewrite, email, cover-letter, resume, essay, story, poem, code, coder, translate, image, image/anime, image/logo, image/poster, image/meme, image/wallpaper, video/generate, music/generate, transcribe, tts.
Yes — /chat/ accepts Korean prompts and replies in Korean. Free signups get 10,000 tokens immediately plus a daily refill pool (resets every 24 hours) that covers normal conversational use. When the daily pool runs out, paid tokens start at $1 = 750,000 tokens; a $5 top-up adds 200,000 tokens at the entry tier. Per-message cost in Korean is roughly the same as English on modern multilingual models — no language surcharge.
Yes — append `?lang=ko` to any URL (e.g. /?lang=ko or /chat/?lang=ko) and the Free.ai chrome (menus, buttons, tooltips, footers) renders in Korean. The selection persists via cookie. Hreflang tags in <head> tell Google to serve the Korean version to Korean-speaking searchers. AI model output itself follows whatever language you write your prompt in — independent of the UI setting.
It varies by engine. Free.ai exposes multiple TTS engines at /voice/ko/ — Kokoro and Piper for fast on-device-quality synthesis, Chatterbox for expressive long-form, and MeloTTS for multilingual coverage. For Korean, MeloTTS and the premium engines give the most natural prosody; the smaller models trade naturalness for speed. Paste a sample on /voice/ko/ and the page renders the same text across engines so you can pick by ear.
Yes — /transcribe/ko/ runs Whisper-large on Korean audio. Word error rate (WER) on clean studio audio is typically 5-12%; noisy phone calls or heavy regional accents push WER higher. The API endpoint `/v1/transcribe/?language=ko` lets you pin the language so Whisper does not autodetect wrong on short clips. Output formats: TXT, SRT, VTT, JSON with word-level timestamps.
Yes — /translate/ does both directions. Free.ai uses a mix of NLLB-200 (Meta's 200-language model) and premium models depending on the pair. Popular pairs have dedicated landing pages — try /translate/en-ko/ for English→Korean or /translate/ko-en/ for Korean→English (where available). The API endpoint is `/v1/translate/?target=ko` — POST your source text in the request body. There is no per-character minimum; short strings and full documents both work.
Yes, with a caveat. /image/generate/ accepts prompts in Korean, but every major open and commercial image model (Flux, SDXL, Seedream, Ideogram, etc.) was trained primarily on English-captioned images. Korean prompts work, but the tightest prompt-following comes from English. If quality matters, run your prompt through /translate/ first (or use /v1/translate/?target=en in the API) and feed the English version to /image/generate/. Rendering Korean text inside images requires Ideogram or a similar text-aware model — most other models will produce gibberish glyphs.
Yes. Free.ai serves UTF-8 everywhere, and Korean (CJK characters) renders cleanly in all tools — including chat history, transcription output, TTS scripts, and PDF/document exports. Our system fonts include CJK fallbacks (Noto Sans CJK), so even mixed Latin + Korean text in /write/blog/ exports without tofu boxes.
Yes. /write/blog/, /write/essay/, and /write/email/ all accept a topic in Korean and produce output in Korean. Under the hood these route to the same chat models, so anything /chat/ does in Korean the writing tools also do. SEO tools (/seo/, /write/title/) generate Korean-language titles and meta descriptions when you set the target locale.
Same rates as every other language. $1 buys 750,000 tokens; a $5 top-up gets 200,000 tokens at the entry tier; free signups receive 10,000 tokens immediately plus a daily free pool that covers everyday chat and translation. Korean input and output tokenizes at roughly the same rate as English on modern multilingual tokenizers (BPE / SentencePiece), so a Korean chat costs about the same as the equivalent English chat. No language carries a surcharge.
Yes. The same endpoints used by the web UI accept Korean input transparently — `/v1/chat/` takes a `messages` array in any language and replies in the same one. For translation, POST to `/v1/translate/?target=ko` with the source text. For transcription, pin the language with `/v1/transcribe/?language=ko` so Whisper does not autodetect wrong on short audio. For TTS, POST to `/v1/tts/` with `language=ko` to pick the right voice automatically. Auth: Bearer token from /api/. See /api/ for SDK snippets and rate-limit details.
Free.ai supports 100+ languages with dedicated landing pages at /languages/. The full list covers every language Whisper, NLLB, and the major chat models handle — including all official EU languages, every major Asian language, Arabic and Hebrew, and a growing roster of African and Indigenous languages. Each language page (like this one for Korean) lists which surfaces currently support it.
