CAPER Releases Major Update to AI HR Assistant 'OpenSeek', Enabling Full Recruitment Operations via Slack

CAPER (Headquarters: Shibuya-ku, Tokyo; CEO: Shun Yamashita) has released a major update to its AI-powered HR assistant, 'OpenSeek'.

With this update, recruiters can now manage their entire recruitment workflow—including organizing requirements, sourcing candidates, generating outreach messages, executing actions, building relationships, and scheduling interviews—simply by conversing with OpenSeek within Slack. This enables companies without a dedicated recruitment team to conduct attentive hiring practices by deeply understanding the experience of each candidate. (A dedicated chat UI is also available for companies that do not use Slack.)

Background: The Increasing Complexity of HR Roles
Since its release in April 2025, our service has been utilized by over 70 companies. Through this support, we have observed the reality that the job of 'HR recruitment' has become increasingly complex due to the proliferation of numerous tools and services.
While AI-powered development tools like ClaudeCode and Cursor are becoming standard in engineering, HR departments still rely heavily on labor-intensive tasks and outsourcing. Furthermore, outsourcing is often costly and inaccessible to many firms.
CAPER believes that by delegating recruitment tasks to an AI HR assistant within Slack, anyone can realize high-quality, attentive hiring practices regardless of resource constraints.

Update Details: Just Chat in Slack; Humans Make Final Decisions
Traditional recruitment services often require logging into dedicated management screens and manually assembling search criteria. With OpenSeek, recruiters simply speak to the AI in Slack. The AI understands their intent and assists with candidate research, proposals for outreach, message drafting, and execution.
Crucially, the decision of who to approach and how remains entirely with the human. The AI handles research and proposals, and tasks are only executed once the recruiter approves them. The design philosophy of OpenSeek is not to replace human judgment, but to extend human recruitment power.

Six Things the AI HR Assistant Can Do
1. Articulating Recruitment Requirements: Simply by saying, 'I want to hire a senior engineer strong in AI with an annual salary range up to 10 million yen,' OpenSeek delves into requirements and articulates the ideal candidate profile.
2. Cross-platform Searching & Proposals: The AI searches across 15+ sources, including recruitment social media, GitHub, blogs, technical articles, presentation materials, and research papers. It analyzes actual outputs to assess fit, proposing only the best-suited candidates.
3. Drafting & Sending Scout Messages: The AI automatically generates 1-to-1 messages that reference the candidate’s specific outputs or activities. Outreach is executed via the optimal channel (e.g., SNS or email) upon approval.
4. Mid-to-Long-term Follow-up: Top talent cannot always be hired immediately. The AI proposes maintaining relationships with candidates who didn't reply or weren't available at the time, triggering follow-ups based on career changes. It executes this faithfully with your permission.
5. Interview Scheduling & Preparation: The AI manages scheduling based on responses, completing the process within Slack. It can also automatically prepare interview materials (e.g., questions inferred from candidate interests and past output).
6. Automating Other Media and Services: The AI also consolidates initial responses to candidate recommendations from recruitment agents and manages existing recruitment services within Slack.
