ひらめき庫 | LINE AI第二の脳

Hirameiki-ko is an "AI second brain" that develops your confirmed goals, preferences, and decision-making criteria through ongoing conversations with a LINE official account.

What You Can Do

• Consult, save, and search using your everyday language on LINE
• Review AI-organized candidates before reflecting them in long-term memory
• Confirm, correct, and forget memories
• Save text and URLs to your library
• Organize with tags and projects, and search using natural language
• Initial web questionnaire of approximately 8-10 minutes with 13 questions, followed by guided deep-dive dialogue on LINE

From the web management screen, you can also edit and delete library items, export data, manage contracts, and delete accounts. Currently, importing images, PDFs, and audio is not supported.

Pricing

The free plan includes 100 saved items, 2 projects, 20 AI questions/month, 10 URL saves/month, and 20 AI searches/month.

The paid plan costs ¥980/month (tax included) with a free trial for the first 14 days. Card registration is required at signup. If you do not cancel before the free period ends, the initial charge will be applied, and it will automatically renew every month thereafter. If you cancel during the free period, you will not be charged.

Using Safely

Only use content you have confirmed yourself for long-term memory, which you can correct or forget later. Card information is not retained by the service but is entrusted to Stripe. AI responses may contain errors, omissions, or biases, so do not make important decisions in medical, legal, financial, or similar matters based solely on AI. Do not send confidential information or detailed health information.
