Choose your access
Permanent Free License
No expiry • No device limit • Use KM AI with purchased tokens
Use the exact same name and email you registered with.
50 prompt generations + 10 Library actions daily
Your permanent key is always shown here. An email copy is also sent.
1. CHOOSE YOUR ACCESS
Permanent Free License
Enter your name and email, then select Get Free License. Save the key shown on screen; it is also sent to your email. Free access has no expiry and can use KM AI with purchased tokens. It includes 50 successful prompt generations and 10 combined Library actions each Manila calendar day.
Lifetime Access — US$50 one time
Buy at Store to receive a separate Lifetime License. It unlocks personal Gemini and ChatGPT API-key providers, has no device limit, and includes 2,500 promotional KM AI tokens. Your own Gemini or ChatGPT usage is billed separately by those providers.
KM AI token packs
Token packs are separate prepaid purchases. KM sends a separate email containing the one-time Purchase Redemption Code; the Gumroad receipt records payment only. The first signed-in KM account that redeems the code receives the tokens, so a code may be given as a gift. It cannot be used again.
2. SIGN IN AND REDEEM TOKENS
Enter the same full name, email, and app License Key used for Free registration or Lifetime purchase, then choose Authenticate.
After signing in, select Buy AI Tokens and choose one package; its direct Gumroad checkout opens separately. To add a purchased pack, open the AI Tokens wallet in the header, choose Redeem Purchase Code, and paste the code from the KM AI purchase email. The redemption shortcut in the purchase chooser opens this same wallet action. The purchase email does not need to match your KM account email.
3. CREATE A PROMPT
Choose the project type and configure location, style, time, weather, camera, scene elements, materials, and output intent.
A reference image is optional. Uploading it only loads the image. Turn Auto-Scan AI ON when you want a one-time KM AI scan; after you confirm the one-token charge, it turns back OFF when the scan finishes.
Select Generate Prompt for a structured architectural prompt. Select Optimize only after a prompt exists when you want a refined version.
Use Copy to send the final prompt to your clipboard for another image tool, or continue to rendering inside KM AI.
4. RENDER SAFELY
KM AI is the default provider and uses your secure KM AI token wallet. Select a model, quality, and aspect ratio; the cost and projected balance appear before rendering.
Tokens are charged only for a successful KM AI result. If a request fails, times out, or is blocked, the reserved tokens return to your wallet automatically.
Free accounts can use KM AI with tokens. Gemini and ChatGPT with a personal API key are available after signing in with a Lifetime License.
Helpful tips
• Advanced Settings keeps optional camera, motion, weathering, scene, and material controls out of the way until needed.
• Vehicle Plates are available only for Exterior and Interior projects. Auto Format adds a country-appropriate plate instruction; Manual adds only the plate text you enter.
• In downloads, 4K renders offer 1× and 2×; 1K/2K renders offer 2× and 4×. History, Upscale, Watermark, and Library remain available from their tabs.

User Guide - Prompt, Render & KM AI Wallet

Create refined architectural prompts, render with KM AI, and manage your images and token wallet in one place.

Quick Start

1. Upload a reference if you have one.
Use Browse or Screen Capture. Uploading only loads the image; it does not scan automatically. Turn Auto-Scan AI ON and confirm one KM AI token when you want a scan. The token is charged only after a useful result; otherwise no generic description is added to your prompt.
2. Configure the project.
Choose Exterior, Interior, or Floor Plan, then set your country, style, weather, camera, scene elements, materials, and output intent. Advanced Settings contains optional details; Floor Plan keeps scene-only controls out of the way.
3. Generate and refine the prompt.
Select Generate Prompt to build the final structured prompt from your settings. Use Optimize only after a real prompt exists. Copy sends the current final prompt to your clipboard.
4. Render with KM AI.
KM AI is the default provider. Choose a supported model, output quality, and aspect ratio. The screen shows the token cost and projected balance before rendering. A failed request returns its reserved tokens automatically.
5. Work with the rendered image.
Expand to inspect the whole image, use +, −, and Reset to control the view, download at an eligible scale, or send the image to Upscale or Watermark. You can also use it as the next reference image for edits.

KM AI Tokens and Access

Free License: permanent access with no expiry. It includes 50 successful prompt generations and 10 combined Library actions per Manila calendar day. Free users can render with KM AI when their wallet has purchased tokens.
Lifetime Access: US$50 one-time. This gives you a separate Lifetime License, no device limit, personal Gemini and ChatGPT API-key access, and 2,500 promotional KM AI tokens.
Buy and redeem tokens: Buy AI Tokens opens the package chooser. Select one package to open its own direct Gumroad checkout; each checkout has only the package you selected. KM sends a separate email containing the one-time Purchase Redemption Code; the Gumroad receipt records payment only. Open the AI Tokens wallet in the header, select Redeem Purchase Code, and paste it. The shortcut inside Buy AI Tokens opens that same wallet action. The first signed-in account to redeem it receives the tokens; it may be gifted and cannot be reused.
Personal API keys: Gemini and ChatGPT use your own key and are available only after you sign in with a Lifetime License. Your personal API charges come directly from Google or OpenAI.

Project-Specific Controls

Vehicle Plates: Exterior and Interior projects can add plate guidance. Auto Format adds a country-appropriate generic instruction. Manual mode adds only the exact plate text you enter. Floor Plan does not include Vehicle Plates.
Library and History: copy preset prompts, apply preset settings, save useful prompts, and revisit generated prompts or rendered images in this browser.
AI Launchers, Upscale, and Watermark: open external AI tools with your prompt, improve rendered images, and add your branding from the dedicated tabs.

KM AI Wallet

Redeem Purchase Code

Redeem in the AI Tokens wallet after signing in. Paste the one-time Purchase Code from the separate KM AI purchase email. The Gumroad receipt records payment only. The first person to redeem it receives the tokens, so you may use it yourself or give it to a friend. It cannot be used again.

Receiving account Sign in required
This is the giftable purchase code from the separate KM purchase email, not your KM app sign-in license. Only the first redemption succeeds.
