From download to your first image
Four steps. All on your PC.
Start your trial and download
Complete card setup at checkout, then save your activation key and choose Download for Windows. Your 14-day trial starts when checkout completes. When the download finishes, open the installer from Downloads.
Install and open
Follow Windows setup, then open Lemon Latitude from the Start menu. The installer includes the app and supporting software. AI models are a separate download.

About model setup ↗Activate and create
Open Trial & license, paste the key from checkout, and choose Activate this device. Create an image or import a photo to edit. The same key becomes your paid license after the one-time charge succeeds.
Model downloads
Your tools, prepared locally.
Does the installer include the AI models?
No. Local tools downloads the models you approve after installation, with progress, verification, and repair. These downloads are several gigabytes per tool; review the exact sizes in the app. No separate ComfyUI or Python installation is needed.
What if a model download is interrupted?
Return to Local tools and retry setup. Verified cached files can be reused. For a prepared tool, choose Verify / repair. You do not need to purchase again or download the Windows installer again.
When does the trial start?
When Stripe confirms card setup at checkout. Download and model preparation time are included in the 14 days. Reinstalling does not reset it. Cancel from your receipt or manage your trial before the displayed deadline to stop the $79 charge.
I already purchased. How do I activate?
Open Trial & license and enter the activation key from your purchase receipt. No second purchase is needed for the same device. Contact support if you need help recovering your key.
Before you install
Know what your computer needs.
The Windows installer includes the app, Creative Compute Fabric host, and WebView2 installer. AI model cold setup, installed upgrade and crash behavior, and supported GPU, VRAM, memory, and disk requirements are being qualified. A development machine’s specifications are not minimum requirements.
Create, prompt Edit & AI Sharpen
These tools need prepared model packages. In-app setup handles installation, verification, and repair. AI hardware requirements will be published after qualification.
Development measurements
How long does local take?
Sharpen (Tikhonov), ten runs per image on an Intel Core i9-13900HX with 32 GB RAM in September 2026.
| Image size | Measured processing time |
|---|---|
| 1.6 MP · 1536 × 1038 | 0.59–0.63 seconds |
| 25.1 MP · 6160 × 4080 | 11.9–17.2 seconds |
These are native sharpening measurements, not end-to-end AI timings. Performance depends on image dimensions and available memory. AI performance will be reported separately.
