How do we talk to partners who are on Chatwork?
In INARY you can invite external people into a shared space. If a partner stays on Chatwork, email can be brought into INARY with several people running the same address.
Chatwork is for messages. INARY is where you decide, with AI.
Chatwork is a Japanese business chat widely used by small and mid-sized companies. INARY is built on the premise that the AI is inside the conversation. Here is the comparison on pricing, free-plan limits, and AI, using each company's published figures.
Pricing (official sites, as of September 28, 2026)
Chatwork lists Business at ¥700 per user per month (annual; ¥840 monthly) and Enterprise at ¥1,200 (annual; ¥1,440 monthly). The free plan shows the latest 5,000 messages posted within the last 40 days, allows up to 100 users per organization, and 5GB of storage per organization.
INARY is free to start with unlimited members (90 days of history). Paid plans are US$4.79 per user per month (annual) for 1 to 30 people, US$4.31 for 31 to 100, and US$3.35 for 101 to 299. AI is billed by usage rather than by seat, and an administrator can set a cap.
How AI is handled
Chatwork's pricing page does not describe AI features. In INARY, the AI is inside the conversation on every plan. It researches with the thread's context, and the answer appears in the same thread for everyone to read. ChatGPT, Claude, Gemini, and Grok are available in one account.
When Chatwork is the better fit
Chatwork is simple to use, and many Japanese business partners already have it. If you want external conversations on a chat your partners already use, and you do not need AI, staying on Chatwork is the sensible choice.
When INARY is the better fit
Teams that want to research, organize, and decide in the shared space, not just exchange messages, and want AI for everyone rather than a few, are a better fit for INARY. It is free with unlimited members, so one team can try it first.
Can we use INARY alongside Chatwork?
Yes. Start by moving only the discussions that use AI into INARY and keep messaging on Chatwork.
Where can I check the prices?
INARY's prices are on the pricing page. Chatwork's prices are on Chatwork's official site. The figures on this page are as published on September 28, 2026.
