GalleryPlanner is a local-first web app for planning gallery walls with real measurements, real frame sizes, and your own photos.

Instead of guessing on the floor and hoping it translates to the wall, you can set your exact wall dimensions, add your frame inventory, and design layouts to the inch before you hammer a single nail.

The app combines manual control with AI assistance:

  • Smart Layout can generate balanced arrangements (Grid, Masonry, Skyline, Spiral, and more), then you can refine details manually.
  • Smart Fill can recommend which photos should go in which frames using local analysis for composition, color harmony, and faces.
  • Precision tools like snapping, nudging, spacing controls, and measurement-aware positioning help you move from idea to install-ready plan.

GalleryPlanner is built with privacy in mind. Your photos stay on your device (browser storage), and core planning workflows run in-browser. No forced cloud photo uploads.

When your layout is ready, you can export outputs for real-world execution, including a printable PDF hanging guide with exact coordinates and project bundles for backup/transfer.

SimpleX features and specs

  • Simple and intuitive interface
    SimpleX provides a clean, straightforward interface for decision-making that doesn't overwhelm users with unnecessary complexity, making it accessible to people without technical expertise.
  • Structured decision framework
    The tool helps users organize their thinking by providing a structured approach to evaluating options against multiple criteria, reducing the likelihood of overlooking important factors.
  • Free to use
    SimpleX appears to be a free web-based tool, making it accessible to anyone who needs help making decisions without requiring a financial commitment.
  • Web-based accessibility
    As a browser-based application, SimpleX requires no software installation and can be accessed from any device with an internet connection, making it convenient for quick decision-making on the go.
  • Visual comparison of options
    The tool provides a visual representation of how different options compare against each other across various criteria, making it easier to see which option comes out ahead overall.

Possible disadvantages of SimpleX

  • Limited advanced features
    SimpleX focuses on simplicity, which means it may lack more sophisticated decision analysis features such as sensitivity analysis, probability weighting, or Monte Carlo simulations that more advanced tools offer.
  • Low visibility and community
    SimpleX is a relatively niche tool with a small user base, which means limited community support, fewer tutorials, and less peer feedback compared to more established decision-making platforms.
  • Potential oversimplification
    For complex decisions involving many interdependent variables, the simplified framework may not adequately capture nuances, dependencies, or non-linear relationships between criteria.
  • Limited collaboration features
    The tool may lack robust collaboration capabilities for team-based decision-making, such as real-time co-editing, role-based access, or voting mechanisms for group consensus.
  • No offline functionality
    Being a web-based tool, SimpleX requires an internet connection to function, which can be a limitation in situations where connectivity is unreliable or unavailable.

What makes your product unique?

GalleryPlanner's answer:

GalleryPlanner blends precision + privacy + AI in one tool.

  • True-to-scale planning: design with exact wall and frame dimensions.
  • Local-first by default: your personal photos stay on-device.

Bottom line: it is not just a mood-board app, it is a practical planning workflow from idea to install.

Why should a person choose your product over its competitors?

GalleryPlanner's answer:

Choose GalleryPlanner if accuracy and execution matter.

  • More practical than generic mockup tools: built for real frame inventory and real wall measurements.
  • Privacy-first workflow: no forced cloud upload of family photos.
  • Faster design decisions: AI-assisted layout and photo placement.
  • Clear value model: free core planning, plus one-time Pro for advanced AI/export workflows.

Compared with tools like ArtPlacer and other broad visual planners, GalleryPlanner is optimized for people who want to actually hang the wall confidently.

How would you describe the primary audience of your product?

GalleryPlanner's answer:

Primary audience: people planning real gallery walls in real homes.

  • Homeowners and renters
  • Families using personal photos
  • Design-focused DIY users

It is especially useful for anyone who wants a measurable plan, not just visual inspiration.

What's the story behind your product?

GalleryPlanner's answer:

GalleryPlanner was created by Tim Straub, a data scientist, after a real home project: turning a growing family frame collection into a clean wall layout with exact spacing.

Existing options did not meet two core needs:

  • precision (exact nail placement and spacing),
  • privacy (no unnecessary cloud photo uploads).

So he built GalleryPlanner as a local-first, measurement-accurate planner for practical, confidence-first installs.

Which are the primary technologies used for building your product?

GalleryPlanner's answer:

Core stack

  • React 19 + TypeScript + Vite
  • CSS Modules UI architecture
  • IndexedDB/browser storage for local-first persistence

Feature stack

  • TensorFlow.js tooling for on-device photo analysis
  • Clerk for account/auth flows
  • Lemon Squeezy for Pro purchase and entitlement workflows

Who are some of the biggest customers of your product?

GalleryPlanner's answer:

  • DIY homeowners
  • families planning personal gallery walls
  • independent interior designers using client previews
