Guide for Tenants & Owners

Last updated: 2026-03-17

Welcome to Baubiber! Whether you're a tenant reporting a maintenance issue or a property owner planning a renovation, this guide walks you through using the mobile app to capture your project, get AI-powered analysis, and find the right professionals — all from your phone.

Getting Started

  1. Download the app from the App Store (iOS) or Google Play (Android).
  2. Sign up with your Google, Apple, or Microsoft account — or use email OTP.
  3. Choose your role — select Baukuki (tenant / owner) when prompted.

Creating a Project

Baubiber supports three project types depending on the scope of your renovation:

Small Fix

For quick repairs like leaky faucets, broken doors, or cracked tiles. The fastest path from problem to solution.

  1. Tap New Project and select Small Fix.
  2. Take photos of the problem area — the more angles, the better the AI analysis.
  3. Add a voice note or written description if you want to provide extra context.
  4. Submit — AI analyzes your photos within seconds.

Small Update

For room refreshes like repainting walls, swapping fixtures, or updating flooring.

  1. Select Small Update and photograph the room from multiple angles.
  2. AI generates 2–3 distinct solution options at different budget levels.
  3. Review the options and select the one that matches your vision.

Full Renovation

For major construction work — kitchen remodels, bathroom overhauls, full apartment renovations.

  1. Select Full Renovation and complete the guided questionnaire.
  2. Upload photos of every room involved.
  3. AI generates solution options plus photorealistic moodboards showing what the finished space could look like — in styles like Modern, Scandinavian, Industrial, or Minimalist.
  4. Select your preferred option to move forward.

AI Analysis

After you upload photos, our AI (powered by Google Gemini) automatically:

  • Identifies issues — water damage, paint wear, plumbing problems, electrical concerns, structural issues, and more.
  • Classifies severity — Minor (green), Moderate (orange), or Urgent (red).
  • Shows confidence scores — so you know how certain the AI is about each finding.
  • Detects rooms — kitchen, bathroom, living room, bedroom, and others.

You can review the full analysis in your project's Current State tab.

Solution Options & Moodboards

For Small Updates and Full Renovations, AI generates 2–3 renovation approaches. Each option shows:

  • What is being preserved vs. replaced
  • Key materials needed
  • Scope level (cosmetic, moderate, extensive)
  • Estimated budget range

For Full Renovations, you also get AI-generated moodboards — photorealistic visualizations of your renovated space in different design styles.

3D Property Capture

On supported devices with LiDAR, you can create an interactive 3D model of your room:

  1. Open the 3D capture feature in your project.
  2. Follow the guided 8-shot camera flow — the app tells you exactly where to point.
  3. Our 3D engine (powered by WorldLabs) reconstructs an interactive model you can rotate and explore.

Finding Professionals

Once your project is ready:

  1. Tap Submit to Marketplace — AI generates a professional contractor report with effort estimates, required trades, and material specs.
  2. Our matching engine finds professionals based on skills, location, and availability.
  3. Matched professionals can view your project and submit offers.

Comparing Offers

As offers come in, you will see them on the Offer Leaderboard:

  • Range pricing — a min-max estimate
  • Capped pricing — a guaranteed maximum
  • Fixed pricing — an exact quote

Contractor profiles are anonymized during bidding to ensure fair comparison based on scope and price.

Messaging

Each project has its own conversation thread. You can message matched contractors to clarify scope, ask questions, or share additional photos and documents.

Managing Properties

If you own or manage multiple properties:

  • Add each property to your portfolio with address, type, and size.
  • Generate a QR code per property — scan it to instantly create a new project linked to that property.
  • View all projects grouped by property.

Property Finances

Track spending on each property with built-in budget and cost management:

Budgets

  • Create Ongoing budgets for recurring costs (utilities, maintenance, insurance) with a ready-made template.
  • Create Project budgets for renovations — organized by room and trade (e.g., Kitchen/Plumbing, Bathroom/Tiling).
  • Link project budgets to your Baubiber renovation projects for unified tracking.

Cost Tracking

  • Record expenses with amount, date, description, and vendor.
  • When a contractor sends you an invoice, tap "Add to Budget" — the amount, date, and vendor auto-fill from the invoice.
  • Browse all transactions in a filterable log.

Financial Dashboard

  • See total budget vs. actual spent at a glance with color-coded progress bars.
  • Dual-currency support — track in one currency, view totals in another.

Collaboration

  • Invite a partner, spouse, or property manager to view or edit your property's finances.

Settings

  • Language — switch between English and German at any time.
  • Dark mode — toggle light and dark themes.
  • Support — reach us at hello@baubiber.com.
