Docbrain

Stop writing docs after the fact. Capture knowledge where it happens.
DocBrain intercepts knowledge at the moment of creation — from PRs, Slack threads, CI pipelines, and IDE sessions — then scores, reviews, and publishes it before anyone has to ask "where's the doc for this?"

The Problem

You know this cycle. Every engineering team does.

Monday: Senior engineer explains the retry logic in a PR review. Three people learn it. The knowledge lives in a GitHub comment thread that nobody will ever find again.

Wednesday: New hire asks "how do I deploy to staging?" in Slack. Someone writes a 4-paragraph answer. It's accurate today. In three months it'll be wrong, and nobody will update it.

Friday: Incident war room. The team discovers that the runbook is 6 months stale. The person who wrote it left the company. Tribal knowledge saves the day, but only because the right people were online.

Next quarter: Leadership says "we need to invest in documentation." You schedule a doc sprint. Engineers write docs for two weeks. Six months later, 40% of those docs are stale. The ones that aren't stale are the ones nobody needed to change because nothing changed.

The root cause isn't laziness. It's timing.

Documentation written after the work is done is documentation written from memory, without context, under competing priorities. It's a tax that nobody wants to pay — and when they do pay it, the result decays immediately.

Every tool in the market solves the wrong problem. They index your existing docs and build a chatbot on top. Great — now you have a chatbot that surfaces your stale, incomplete, scattered documentation slightly faster.

The actual problem is that the knowledge was never captured in the first place.

How DocBrain Fixes It

DocBrain doesn't wait for someone to write a doc. It intercepts knowledge at the point of creation and turns it into documentation automatically. We call this shift-left documentation — the same principle that made shift-left testing work. Move the capture upstream, to where the knowledge actually exists.

                         WHERE KNOWLEDGE IS CREATED
                         ─────────────────────────

  queue low for review,  on every fragment   into full docs      → published
  discard noise          and document        when cluster ready  to your wiki

This is what makes DocBrain different. Other tools index existing docs and answer questions about them. DocBrain captures the knowledge that was never written down — the PR decisions, the Slack explanations, the deployment gotchas, the incident resolutions — and turns it into documentation that meets your team's quality standards.

The result: documentation that's born from real work, not written from memory. Documentation that's quality-scored the moment it exists, not left to rot. Documentation that gets better as your team works, not worse.

Why DocBrain

For Engineers

• Zero extra work. Knowledge is captured from PRs, commits, Slack threads, and CI pipelines you're already using. No context-switching to a wiki.
• Capture from your IDE. docbrain_annotate, docbrain_suggest_capture, and docbrain_commit_capture via MCP — works in Claude Code, Cursor, and any MCP-compatible editor.
• Quality gates in CI. Lint docs with custom style rules, enforce structure, catch stale content before it ships. POST /api/v1/quality/lint plugs into any CI pipeline.
• Ask, don't search. Query your entire knowledge base with confidence-scored answers that cite sources. No more digging through Confluence.

For Engineering Managers

• Know what's documented and what isn't. Governance dashboards show coverage per space, per team. See exactly where the gaps are.
• SLA enforcement. Per-space policies ensure gaps are acknowledged within 24h and resolved within 7 days. Automated breach detection with notifications.
• ROI tracking. Documentation velocity, time saved per query, resolution rates, and knowledge half-life — per team, in dollars.
• Review workflows. Multi-stage approval pipelines (SME Review → Writer Review → Publish) with threaded comments, so nothing goes live without oversight.

For Platform Teams

• Self-hosted, single binary. Rust backend, no JVM, no Python dependency hell. Docker, Kubernetes, or bare metal. Sub-100ms API responses.
• 14 LLM providers. Anthropic, OpenAI, AWS Bedrock, Ollama (fully local), Gemini, and 9 more. Swap providers without changing a line of code.
• 13+ knowledge sources. Confluence, Slack, Teams, GitHub, GitLab, Jira, PagerDuty, and more. Connector SDK for anything else.
• Full OpenAPI spec. Swagger UI at /api/docs. Auto-generated OpenAPI 3.1 spec. 150+ API endpoints.
• RBAC, SSO, space isolation. GitHub/GitLab/OIDC SSO, 4-tier role system (viewer/editor/analyst/admin), per-space access restrictions.
• Event-driven. Real-time event bus with SSE streaming. Outbound webhooks with HMAC-SHA256 signing, exponential backoff, and circuit breakers.

Features

Shift-Left Knowledge Capture

The core of DocBrain. Every integration point captures knowledge where it's created — before anyone has to remember to document it.

Capture Point	How It Works
Merged PRs	POST /api/v1/ci/analyze — LLM extracts decisions, facts, caveats, and procedures from diffs and commit messages. Hook it into GitHub Actions or GitLab CI.
Deployments	POST /api/v1/ci/deploy-capture — Captures deployment context, environment changes, and rollback procedures.
Slack & Teams	Capture threads via message shortcut, @DocBrain capture mention, or /docbrain capture — distills conversations into knowledge fragments with confidence scoring.
IDE (MCP)	docbrain_annotate links knowledge to exact code locations. docbrain_commit_capture captures intent at commit time. 10 MCP tools total.
Conversations	Auto-distillation extracts fragments from Q&A sessions. When someone asks a question and gets a good answer, that answer becomes a fragment automatically.
Manual	POST /api/v1/fragments — Teams can submit fragments directly. CLI: docbrain capture.

What happens after capture: Every fragment is confidence-scored and routed automatically:

• High confidence (>0.7): Auto-indexed into search, immediately available for Q&A
• Medium confidence (0.4–0.7): Queued for human review
• Low confidence (<0.4): Discarded as noise

Knowledge Quality Pipeline

Every fragment and document is scored across three independent layers — no unscored content enters the system:

Layer	Method	What It Measures
Structural	Deterministic (no LLM cost)	Heading structure, section completeness, code examples, link density, readability
Style	Rule engine	Banned terms, heading depth, sentence length, required sections, custom regex
Semantic	LLM-assessed (budget-controlled)	Accuracy, clarity, completeness, actionability

Composite score: structural x 0.4 + style x 0.3 + semantic x 0.3

Quality scores drive automation: low-scoring docs trigger maintenance suggestions, stale docs trigger freshness alerts, and contradictions between docs are flagged automatically.

Custom Style Rules — Your Style Guide, Enforced Automatically

Every team has a style guide. Nobody follows it. DocBrain enforces it on every document and draft:

# Export your rules as YAML, version-control them, import across spaces
- rule_type: terminology
  name: no-simple
  description: "Don't assume expertise — avoid 'simple' and 'easy'"
  config:
    wrong: "simple"
    right: "straightforward"
    match_whole_word: true
  severity: warning

- rule_type: formatting
  name: short-sentences
  description: "Keep sentences under 40 words for readability"
  config:
    max_words: 40
  severity: info

- rule_type: structure
  name: require-intro
  description: "Every doc needs an introduction before the first heading"
  config:
    min_words_before_first_heading: 10
  severity: warning

- rule_type: custom_pattern
  name: no-internal-urls
  description: "Don't leak internal URLs in public docs"
  config:
    pattern: "https?://internal\\."
    message: "Remove internal URL before publishing"
  severity: error

Four rule types: terminology (banned/preferred terms), formatting (heading depth, sentence length), structure (required sections, intro paragraphs), and custom_pattern (regex for anything else).

Per-space scoping: Different rules for API docs vs. runbooks vs. onboarding guides.

YAML import/export: Version-control your rules. GET /api/v1/style-rules/export → commit to git → POST /api/v1/style-rules/import on deploy.

Lint any text on demand: POST /api/v1/quality/lint with raw text → get violations with line numbers, severity, and fix suggestions. Wire it into CI to block PRs that break your style guide.

Governance & Accountability

Documentation without ownership decays. DocBrain makes ownership and accountability explicit:

• Space ownership — Owners, maintainers, and topic stewards per knowledge space. Clear responsibility chains.
• SLA policies — Per-space deadlines for gap acknowledgment (24h), resolution (7d), draft review (48h), and document freshness. Configurable per space.
• Breach detection — Automated scanning surfaces SLA violations. Breaches trigger events, notifications, and webhook deliveries.
• Governance dashboard — Coverage percentages, SLA compliance trends, quality distribution, capture velocity, and top contributors — all in one view.
• Notifications — In-app notification center with unread tracking. SLA breaches, review assignments, and gap alerts delivered to the right people.

See Governance Guide for setup and configuration.

Review Workflows

Configurable multi-stage review pipelines for documentation drafts:

• Define stages per space — e.g., SME Review → Technical Writing → Publish Approval. Each stage has assigned reviewers and required approvals.
• Submit for review — Autopilot drafts, manually written docs, or composed fragments can all enter the review pipeline.
• Approve / Request Changes / Reject — Reviewers act on drafts with threaded comments for inline feedback.
• Personal review queue — Every reviewer sees their pending items in one place.
• Auto-publish on approval — When all stages pass, the document publishes to your configured target (Confluence, etc.).

See Review Workflows Guide for configuration and API details.

Intelligent Q&A (RAG)

• Confidence-scored answers — High confidence returns sourced answers with citations. Low confidence asks clarifying questions instead of guessing.
• Intent classification — Adapts response format to query type: find, how-to, troubleshoot, who-owns, explain. Each gets a different answer structure.
• Hybrid search — OpenSearch with both vector (k-NN) and keyword (BM25) retrieval, combined for precision.
• 4-tier memory — Working, episodic, semantic, and procedural memory that compounds over time. The system gets smarter with use.
• Document freshness — 5-signal scoring (time decay, engagement, content currency, link health, contradiction detection) with staleness alerts.

Documentation Autopilot

The autonomous documentation engine that finds and fills gaps without human intervention:

• Gap detection — Clusters unanswered questions and low-confidence answers by semantic similarity. Severity scoring based on user count, negative signal ratio, and recency.
• Draft generation — AI composes missing documentation grounded in existing docs, fragments, and conversation context. No hallucination — every claim must be sourced.
• Review routing — Generated drafts automatically enter the review workflow for human approval. Nothing publishes without oversight.
• Weekly digest — Summary of gaps detected, drafts generated, and coverage changes delivered to space owners.
• Forecast — Predictive gap analysis shows where documentation gaps are likely to appear next.

See Autopilot Guide for configuration and tuning.

Fragment Lifecycle

The full journey from captured knowledge to published documentation:

Capture → Confidence routing → Auto-index / Review queue / Discard
                                       │
                    Semantic clustering (DBSCAN on embeddings)
                                       │
                    Auto-composition when cluster is ready
                    (3+ fragments, 2+ sources, shared topic)
                                       │
                    Quality scoring (structural + style + semantic)
                                       │
                    Review workflow (configurable stages)
                                       │
                    Published documentation

Predictive Intelligence

DocBrain doesn't just document what exists — it predicts what's about to break:

• Cascade staleness — When one document changes, which other docs become stale? Dependency graph analysis surfaces cascade effects before they cause incidents.
• Seasonal patterns — Recurring documentation needs (quarterly reviews, annual compliance, onboarding seasons) predicted from historical patterns.
• Onboarding gap detection — Documents that new hires struggle with, ranked by friction score.
• Code change analyzer — Submit a PR diff, get back a list of documentation that needs updating. Wire it into CI to block merges when docs are impacted.

Knowledge Graph & Analytics

• Entity graph — Relationships between documents, people, teams, and topics. BFS/DFS traversal, blast radius analysis, and shortest-path queries.
• Expert finder — "Who knows about Kubernetes networking?" → ranked list of contributors by topic, based on authorship and review activity.
• Documentation velocity — Gap resolution rate, knowledge half-life, ROI in USD, capture velocity per team. Grade-based scoring (A–F) per space.
• Freshness scoring — 5-signal composite score with contradiction detection. Two docs that say different things about the same topic? Flagged automatically.
• Autonomous maintenance — Contradiction fixes, link repairs, version updates — surfaced as suggestions with one-click apply.

See Knowledge Intelligence Guide for details.

Connector SDK — Plug In Any Source

Build a connector for any knowledge source in any language. DocBrain handles scheduling, retries, circuit breaking, and ingestion — your connector just serves three HTTP endpoints:

GET  /health           → { "status": "ok", "connector_name": "notion" }
POST /documents/list   → Return document IDs (paginated, incremental via "since")
POST /documents/fetch  → Return full document content for given source IDs

Register it in DocBrain, set a cron schedule, and every document flows through the same quality pipeline as built-in sources. Includes SSRF protection, circuit breaker (auto-disable after 5 failures), and incremental sync. Connector Protocol Docs →

MCP IDE Capture

10 tools for Claude Code, Cursor, and any MCP-compatible editor:

The LLM is required — it powers RAG, intent classification, quality scoring, and draft generation. You choose where it runs:

Option	Data leaves your network?	Best for
Ollama (local)	No. Zero egress.	Air-gapped, regulated, maximum control
Bedrock / Azure / Vertex	Stays in your cloud account	Enterprise — your KMS, your VPC, your audit trail
Anthropic / OpenAI / etc.	Query + chunk context sent via TLS	Fastest setup, best model quality

What data goes where:

Data	Stays in your infra	Sent to LLM
Documents, embeddings, indexes	Yes (PostgreSQL + OpenSearch)	No
User queries	Yes (episodes table)	Yes — needed for answer generation
API keys, passwords	Yes (Argon2 hashed)	No
Chunk context for answers	Yes (OpenSearch)	Yes — relevant chunks only, not full corpus
Analytics, gap clusters, feedback	Yes (PostgreSQL)	No

Security controls:

Control	Implementation
Authentication	API keys with Argon2 hashing, OIDC/SSO (GitHub, GitLab, generic OIDC)
Authorization	4-tier RBAC (Viewer → Editor → Analyst → Admin) enforced on every endpoint
Space isolation	Per-key allowed_spaces hard-filters search results — users only see their team's docs
Rate limiting	Per-key RPM limits with sliding window
Secrets	Keys shown once at creation, stored as hashes. Bootstrap key written to file with 0600 permissions
Audit	All admin actions logged with user, action, timestamp, and target
SQL injection	Compile-time verified parameterized queries (sqlx) — no string interpolation
Prompt injection	XML delimiter sanitization on all untrusted content entering LLM context
Webhook verification	HMAC-SHA256 signed payloads for inbound webhooks (Confluence, GitHub, GitLab)

For the full threat model with 10 analyzed attack vectors and an operator security checklist, see THREAT_MODEL.md.

Deployment

Docker Compose

docker compose up -d

Starts the API server (localhost:3000), web UI (localhost:3001), PostgreSQL, OpenSearch, and Redis. Migrations run automatically on first boot.

Kubernetes

helm install docbrain ./helm/docbrain \
  --set llm.provider=anthropic \
  --set llm.anthropicApiKey=sk-ant-...

See Kubernetes Guide for production configuration, scaling, and monitoring.

Configuration

DocBrain uses a config-first architecture:

File	Purpose
config/default.yaml	Non-secret defaults — all features, thresholds, intervals
config/local.yaml	Credentials and local overrides (gitignored)
.env	Infrastructure secrets: DATABASE_URL, LLM API keys

Environment variables always override config files. See Configuration Guide.
