The verdict: can you vibe code Slab?
Build a personal documentation wiki with markdown editing and basic vector search, but bypass the complex multi-app OAuth sync pipelines and realtime multiplayer CRDT infrastructure.
Creating a clean documentation repository with markdown topics, folder trees, and an AI assistant is entirely feasible as a solid side project using modern web frameworks. However, replicating Slab's exact multi-app unified search engine—which indexes live data streams from Slack, GitHub, and Google Drive while maintaining strict permission boundaries—involves immense maintenance friction for a solo builder. Furthermore, implementing robust realtime cursor co-editing without dedicated infrastructure libraries will eat up your weekends debugging race conditions.
Estimated effort: 2-3 weeks part-time
What you can't replicate
- Unified OAuth ingestion sync across Slack, GitHub, and Google Drive
- Enterprise SOC 2 compliance and rigorous SAML/SCIM directory provisioning

Build guide
01Project Scaffolding and Database Schema
Initialize a Next.js project with Tailwind CSS, configure Drizzle ORM connected to Neon Postgres, and define the core relational models for users, teams, topics, posts, and document versions.
Create a new Next.js project using App Router and TypeScript. Install Drizzle ORM and configure it to connect to a Neon serverless Postgres database using the connection string from environment variables. Define database schemas in `db/schema.ts` for: `users` (id, email, name, avatar), `teams` (id, name, slug), `topics` (id, team_id, name, description, parent_id), `posts` (id, topic_id, author_id, title, content, status, version, updated_at), and `post_history` (id, post_id, content, edited_by, timestamp). Run migrations and ensure a clean project layout.02Authentication System
Integrate better-auth for secure credential and Google OAuth login, attaching user sessions to organizational workspaces.
Install and configure `better-auth` in the Next.js application to handle user authentication with email/password and Google OAuth providers. Create the required database tables via better-auth schema extensions. Build a sign-in and sign-up page under `app/(auth)/` with validation states. Set up session middleware protecting dashboard routes and ensure user records link cleanly to team workspaces.03Topic and Folder Tree Navigation
Implement a sidebar navigation tree supporting nested Topics, folders, and privacy markers for internal knowledge categorization.
Build a responsive sidebar component for the application dashboard that renders hierarchical Topics and folders fetched from the database. Implement server actions to create, rename, and delete topics and nested folders. Add UI indicators for private topics and pin your favorite topics to the top of the tree view. Ensure optimistic updates update the sidebar immediately upon action execution.04Rich Text Document Editor
Integrate a modern headless markdown or rich-text editor (such as TipTap) with autosave capabilities and document version history logging.
Create the post editor view at `app/posts/[postId]/page.tsx` utilizing an open-source rich text editor library like TipTap or a robust markdown textarea wrapper with toolbar formatting (headings, lists, code blocks, callouts). Implement a debounced autosave server action that persists post title and content changes to the database every 2 seconds. Add a version history drawer that displays past revisions saved in the `post_history` table and allows restoring previous versions.05Verification Workflows & Stale Content Flagging
Add verification tracking to posts so designated maintainers can mark documentation as verified or stale after elapsed time windows.
Add verification attributes to posts: `verified_at` timestamp, `verifier_id`, and `verification_interval_days`. Build a status banner inside the post viewer component that alerts readers if a document is stale (exceeding its interval). Include a 'Verify' action button for designated maintainers to update the verification timestamp and log the review event. Create a dashboard widget listing stale documents across all topics.06AI Assistant and RAG Search Integration
Implement Vercel AI SDK to power document auto-summarization, autofix grammar corrections, and semantic Q&A over internal documentation.
Integrate the Vercel AI SDK (`ai` and `@ai-sdk/anthropic`) into the application. Create an API route for 'AI Ask' that accepts user queries, computes embedding matches or queries pgvector on the documents table, and streams back synthesized answers with citations referencing specific posts. Add an 'AI Autofix' button inside the editor toolbar that sends the current document content to Claude Haiku for grammar correction, clean formatting, and concise summary generation, streaming the result directly back into the editor.
