Knowledge content data for humans and AI alike
Operator-reviewed, high-quality content delivered in HTML, TXT, Markdown, JSON, JSON-LD, RSS and more, across multiple languages. The same content is published as a human-readable page and machine-readable data files at the same time. On top of that, we expose embedding vectors that capture each article's meaning via API, so you can plug it straight into semantic search and AI pipelines beyond simple keywords. Each article can also be listened to as natural AI speech (mp3) generated on the server, so the content can be consumed even when reading is inconvenient. Content for readers, search engines, and AI systems alike.
One content, many formats
The same article is published as a human-readable page and machine-readable data files, so search engines and AI systems can easily collect, understand and cite it. Beyond text formats, we also provide embeddings that represent the content's meaning as vectors, enabling meaning-based search and recommendation that go beyond keywords. Add server-generated, high-quality AI speech (mp3) on top, and a single piece of content can be consumed in three ways: read it, take it as data, or listen to it.
Listen to content out loud
You can listen to published articles as AI speech. The audio is pre-generated on the server and starts instantly on most devices, including mobile, free with no login required.
- Instant playback - no model download or preparation wait
- Free · no login required
- Korean, English, Japanese and Spanish, with sentence captions, playback speed and resume
The voice is AI-synthesized (Korean/Japanese/Spanish: Supertonic 3, English: Kokoro 82M). Audio may not be ready yet for some articles.

For AI systems and crawlers
Every article on this site is also available as plain text, Markdown, structured JSON, and schema.org JSON-LD. Start with llms.txt or the data access guide.
If you need many records at once - model training, fine-tuning, RAG indexing - the paid API serves datasets normalized into training-ready schemas. The free data files above stay free exactly as they are.
