Qast

What Qast does

Qast is an AI-powered knowledge management cloud platform operated by any Inc., a privately held Japanese software company headquartered in central Tokyo. Launched in 2018 as an internal Q&A system, Qast has evolved into a comprehensive enterprise platform that helps Japanese organizations convert tacit, individual knowledge into structured, searchable, AI-accessible organizational assets. As of 2026 the platform serves more than 98,000 users across a roster of named enterprise customers including Marui Group (5,500 seats), Tokai Riko (3,200 seats), Bandai, JR East, Elleair Paper, Dynam, Odakyu Fudosan, Digital Garage, and Shueisha, spanning manufacturing, retail, fintech, gaming, railway, real estate, and publishing verticals.

The platform combines generative AI, retrieval-augmented generation (RAG), natural language processing, and AI-OCR computer vision to ingest and operationalize organizational knowledge from heterogeneous sources. Core features include こましりchat (Komashiri Chat), an RAG-based conversational Q&A engine that returns source-cited answers; File to Knowledge, which converts dropped PDFs, Word, Excel, PowerPoint, and handwritten documents into AI-summarized, auto-tagged knowledge posts; Meeting to Knowledge, which transcribes meeting audio into structured records with auto-extracted next actions, plans, and assignees; and AI Knowledge Interview, a Japan-first patent-pending voice-based service that interviews experts to extract tacit knowledge. The platform integrates natively with Slack, Microsoft Teams, Microsoft 365, Google Drive, Azure Active Directory, and supports SAML2.0 single sign-on alongside two-factor authentication via Google Authenticator and Twilio Authy.

Qast operates a B2B SaaS model targeting Japanese enterprises via annual subscription contracts with tiered per-seat pricing (Professional, Professional Plus with AI Knowledge Interview, Premium), bank transfer or credit card billing, and auto-renewal absent 30-day cancellation notice. Distribution combines direct enterprise field sales, inside sales, a self-service 30-day free trial, free demo requests via the company website, and event presence at major Japanese industry exhibitions (DX総合EXPO, Japan IT Week, 産業DX総合展, バックオフィスWorld). The company invested in its first taxi advertising brand campaign on TOKYO PRIME in July 2025 and operates the annual Knowledge Creation Day conference and Qast Lab media platform as thought-leadership channels. Qast holds ISO 27001 certification (IS 754080, BSI Group Japan) and is certified as a METI IT導入補助金 vendor, making it eligible for Japanese SME government subsidies of up to ¥500,000. The company is private with no disclosed funding rounds or external investors in the source data.

Direct peers

• Atlassian (Confluence): Enterprise wiki and knowledge base with deep Jira integrations; the dominant incumbent Qast must displace or coexist with inside Japanese enterprises for internal Q&A and documentation.
• Notion Labs: All-in-one workspace combining docs, wiki, and AI-powered Q&A (Notion AI/Q&A). Competes directly with Qast for the internal knowledge base and search use case among enterprise buyers.
• Guru: Enterprise knowledge management platform delivering verified, in-workflow answers via browser extension and integrations; competes for the same single-source-of-truth internal knowledge use case.
• Tettra: AI knowledge base inside Microsoft Teams and Slack with Q&A and expert identification features that closely parallel Qast's こましりchat and Know Who capabilities.
• Slite: AI-powered knowledge base for distributed teams with similar Q&A, docs, and async decision capture; overlaps with Qast's core internal knowledge management positioning.
• Helpfeel: Japanese AI-powered FAQ and knowledge search SaaS (originally from Nota); competes with Qast's こましりchat for internal and customer-facing question-answering deployments.
• Stockmark: Japanese AI document and enterprise knowledge platform with summarization and search; the most directly comparable domestic competitor targeting similar Japanese enterprise DX budgets.

Others

• HENNGE: Cloud security and SSO provider (HENNGE One) commonly paired with Qast for SAML-based access; ecosystem enabler rather than competitor but indicates the broader Japanese SaaS stack Qast is sold into.

Emerging players

• Chatwork: Leading Japanese business messaging SaaS expanding into knowledge and AI features; competes for the same Japanese enterprise buyer budget and overlaps with Teams/Slack-style workflow integration.

Broad incumbents

• Microsoft (Viva / Loop): Microsoft's employee experience and knowledge platform sits inside Microsoft 365, leveraging Azure AD, Teams, and Copilot that Qast integrates with — represents both a partner channel and the most formidable competitive threat.
