Capture Knowledge From Everywhere
Kioku integrates with the tools you already use, automatically capturing architectural decisions without changing how your team works.
Slack Integration
Automatically detect architectural discussions in your Slack channels. Kioku identifies decision-making conversations and captures them with full thread context.
GitHub PR Mining
Extract decisions embedded in PR descriptions, review comments, and issue discussions. Never lose context buried in closed PRs again.
Meeting Intelligence
Upload meeting transcripts or connect your recording tool. Kioku extracts key technical decisions and action items automatically.
Semantic Search
Ask questions in plain English. "Why did we choose PostgreSQL?" returns the exact decision, discussion context, and participants involved.
Decision Timeline
Visualize how your architecture evolved over time. See which decisions superseded others and understand the full decision chain.
Team Onboarding
Generate personalized onboarding paths. New engineers get a curated tour of the decisions most relevant to their projects and role.
Three Steps to Institutional Memory
Get started in minutes. Kioku works in the background so your team can focus on building.
Connect Your Tools
Link Slack, GitHub, and meeting platforms with one-click OAuth. Kioku starts monitoring for architectural discussions across all your channels.
Decisions Auto-Captured
AI identifies and structures decisions into Architecture Decision Records (ADRs) with context, reasoning, alternatives, and consequences.
Search & Discover
Ask questions in natural language. Get instant answers with full decision history, participant context, and related discussions.
See Decisions in Action
Every decision is captured with full context — who made it, why, what alternatives were considered, and what the consequences are.
Use PostgreSQL with pgvector for Semantic Search
Context
We need to implement semantic search across millions of code snippets and documentation. Traditional full-text search isn't sufficient for understanding user intent and returning contextually relevant results.
Decision
Use PostgreSQL with the pgvector extension for vector similarity search, combined with OpenAI embeddings for vectorization of all content.
Consequences
Works With Your Stack
Connect the tools your team already uses. Kioku pulls in context from everywhere, so nothing falls through the cracks.
Loved by Engineering Teams
See how teams are using Kioku to preserve their institutional knowledge and accelerate onboarding.
“We cut our onboarding time from 6 months to 3 weeks. New engineers can understand years of architectural decisions in days, not months.”
Sarah Chen
VP of Engineering at ScaleOps
“Every time someone asked "why did we build it this way?", we'd spend hours searching Slack. Now it takes 30 seconds with Kioku.”
Marcus Rodriguez
Staff Engineer at Dataflow
“Kioku is like having the institutional memory of your most senior engineer, available 24/7. It's become essential to how we work.”
