Why it's different
A director that understands the brief, writes a professional prompt, generates, checks the result against your base image, and refines — while you stay in control.
Faithful by design
Every round is compared to your original. Building form, floor count, windows, straight lines and text are locked — the model improves materials, light and entourage, not your geometry.
Quota-saving iteration
Local flaws are fixed by an incremental edit on the previous render instead of re-rolling a whole image. Defects converge instead of reappearing.
Confirm gate
The AI first explains what it understood and shows an editable prompt. Approve or adjust — then it starts spending credits.
Hands-on region edits
Mark exactly what to change with freehand, line, rectangle, lasso, smear or eraser — the AI edits only inside the mark.
Two engines, your account
Generate with ChatGPT or Gemini's nano-banana — both drive a browser you're logged into, on your own subscription. No API key.
Curated ArchViz library
Precise material vocabulary (board-formed concrete, Shou Sugi Ban, Corten, zinc standing seam…), lighting scenarios and camera guidance.
Offline vision, no account
The Prompt Assistant can read your image with a local Ollama vision model — fully offline, no account, no VPN.
Local quality boost
Final deliverables upscale to 2K/4K/8K with a local super-resolution model and de-watermark locally — offline, on the final image only.
Bilingual UI (中 / EN)
Work in Chinese; the prompt sent to the model is always English (image models are more reliable in English). Your choice is remembered.
How it works
One director chat runs the whole loop; you review at every checkpoint.
- Describe & upload. A few sentences plus a base image (kept faithful) and optional reference images for mood, material and light.
- Confirm the prompt. The AI paraphrases your intent and shows an editable, professional prompt before any credits are spent.
- Auto-iterate. Generate → tamper/quality check against the base → refine the previous render, or redraw from base if the form drifts.
- Review & export. Pause every N images to leave feedback, mark a region to fix, or export to your Desktop. Every step is saved.
