Business problems it solves
About "LINE WORKS AiNote"
What is LINE WORKS AiNote?
LINE WORKS AiNote is an AI meeting-minutes and transcription tool from LINE WORKS Corp., the company behind the business chat app "LINE WORKS". In a single service, it transcribes meeting audio, tells speakers apart, summarizes the discussion with a template that matches the meeting's purpose, and shares the result with colleagues via a link.
It started as "CLOVA Note β", a free service for individuals. After its registered users passed one million, the official version was launched as LINE WORKS AiNote in November 2024. On February 4, 2025, CLOVA Note β restricted features such as creating notes and switched to a data-migration service into AiNote (the service ended at the end of July 2025).
The official site highlights three strengths: speed—about one minute to transcribe a one-hour meeting, speaker diarization technology that placed third in the world in an international competition, and a low price made possible by in-house development. The paid version was adopted by more than 2,900 companies within one year of launch (announced in May 2026).
Your recorded meeting comes back as text, split by speaker
At its core, AiNote turns a recorded meeting into a transcript separated by speaker. Each utterance carries the speaker's name and a timestamp, and the transcript view also shows each participant's share of the conversation and the main keywords.
According to the official site, the technology that separates speakers (speaker diarization) placed third in the world at the international competition "DIHARD3" (2021).
On the business plans, automatic speaker identification is also available: AI determines who is speaking during the recording. It covers members of your organization who have registered their voice. External participants cannot register voice information for privacy reasons, so they are not identified automatically.
Registering company names, product names and jargon as frequently used words makes them easier to recognize. Each member can register up to 1,000 words per language, and administrators can register up to 1,000 words per language for the whole tenant.

Set a summary format for each type of meeting
For AI summaries, you either pick a purpose-specific template or create a custom template with the headings you need. The official screenshot shows templates such as "Decision-making meeting", "Progress check" and "Sales meeting notes".
The official explanation is that by keeping the same template, the key points are recorded in the same structure even when the person taking minutes changes. This suits meetings where you check the same items every time—regular meetings, sales meetings, committees and so on.
AI summaries have a monthly limit: 12 on Solo, 120 on Team, 360 on Business and 1,200 on Enterprise. They are not available on the Free plan.
Find past meetings by what was said
Notes can be shared with stakeholders via a link and work together with LINE WORKS. Because your accumulated notes are searchable by what was said, you can check "how did we decide that last time?" without reopening old minutes.
The screen on the right shows a search for "pamphlet"; matching utterances are listed with the word highlighted.
You can add bookmarks, memos and highlights to notes, and create notes by importing calendar events (according to the user guide in the Help Center).

How to use
- Set up a LINE WORKS service environment Installing the app alone is not enough to start. Even for individual use, you need to open a LINE WORKS platform account and subscribe to AiNote in the admin console. The Free plan can be set up from a form on a PC, or from "Create service environment" in the smartphone app. For the business plans, apply via the free-trial or application form; after exchanging an application form, the environment is provided within five business days.
- Set frequently used words and the target language Register your company names, product names and industry terms as "frequently used words", and choose the meeting language under "target language". To use automatic speaker identification on a business plan, register members' voice information as well.
- Record the meeting Record in-person meetings with the smartphone app or a browser. For online meetings, enter the meeting URL in "Web meeting recording" and let the bot join. You can also import an existing recording.
- Review the transcript and summarize When transcription is done, check the speakers and content and edit as needed. Then choose a template that fits the meeting and create an AI summary.
- Share Share the note's link with stakeholders. On the Team plan and above, you can also send minutes data to internal systems via the API.
Web meeting recording works in conjunction with services such as Zoom, so "temporarily unavailable" may be displayed while AiNote adapts to changes on their side. During such periods, the Help Center suggests placing a smartphone near the speaker and recording with the app.

Track record and reputation
The paid version was adopted by more than 2,900 companies within one year of launch (announced May 21, 2026). The same announcement reported that AiNote placed third in the Rookie of the Year category of "ITreview Best Software in Japan 2026", a category for products released in 2024 or later that received many highly positive user reviews.
On the Japanese App Store, the app "LINE WORKS AiNote - 文字起こし・議事録" is rated 4.5 out of 5 (4,833 ratings, as of October 16, 2026).
The official site presents three case studies from different industries.
01Healthcare: minutes in about one-third of the time
At Hakodate Goryokaku Hospital (社会福祉法人 函館厚生院 函館五稜郭病院) in Hakodate, Hokkaido, important meetings had to be recorded accurately, and minutes for a one-hour meeting sometimes took more than 15 hours to finish. The hospital reports that AiNote cut the time, which had been up to 15–16 hours, to about one-third.
02Building maintenance: chosen after comparing five tools
Harima Bistem (株式会社ハリマビステム) compared and tested five AI minutes tools for usability, processing speed, cost and security, and chose AiNote for its transcription speed and its operating environment with single sign-on (SSO).
03Car dealership: toward "meetings focused on discussion"
The case of Mie Toyopet (三重トヨペット株式会社) is presented as an effort that greatly reduced the burden of taking minutes, turning "internal meetings spent chasing the record" into "meetings focused on discussion".
