What is the Prompt Assistant?

The Prompt Assistant is an AI chat interface built into every session. It goes beyond simple prompt enhancement — it can plan multi-step generation workflows, recommend models, and help you iterate on your creative vision through conversation.

​
How it works

1

Open the assistant

The Prompt Assistant is accessible from the chat panel in your session. Click the chat icon or use the keyboard shortcut to open it.
2

Describe what you want

Tell the assistant what you’re trying to create. You can be as vague or specific as you like:
  • “I need a hero image for a fitness app landing page”
  • “Create a series of product shots for a coffee brand”
  • “Help me generate a cinematic sci-fi scene”
3

Review the plan

The assistant generates a plan with recommended models, aspect ratios, and refined prompts. You can review and adjust before executing.
4

Execute and iterate

Apply the plan to generate images directly, or continue the conversation to refine your direction.

​
Key features

​
Plan tool

The Prompt Assistant’s primary capability is the Plan tool — it creates structured generation plans that include:
  • Recommended AI models based on your use case
  • Optimized prompts with style, composition, and technical details
  • Suggested aspect ratios and settings
  • Support for both image and video generation
Plans can be applied directly to the generation bar with one click.

​
Model-aware suggestions

The assistant understands the strengths and limitations of each available model. When you describe your goal, it recommends the most appropriate models:
  • Photorealistic needs → Flux 2 Max, Imagen 4
  • Text-heavy designs → Ideogram V3
  • Cinematic video → Kling V3 Pro, Veo 3.1
  • Fast exploration → Flux Schnell, Nano Banana

​
Reference image support

You can attach reference images directly in the chat using drag-and-drop or paste. The assistant will factor these references into its plan, using them to guide model selection and prompt refinement.
Reference images attached in chat are tagged with @image1, @image2, etc., and can be referenced in follow-up messages.

​
Streaming responses

The assistant streams responses in real time, so you see suggestions as they’re generated rather than waiting for the full response.

​
Tips for effective use

Be specific about your end use: Telling the assistant “this is for a social media ad” vs. “this is for a print poster” leads to very different recommendations.
Iterate through conversation: Don’t expect the perfect plan on the first try. Respond with feedback like “make it more dramatic” or “try a wider aspect ratio” to refine.
Attach references: Drag and drop reference images into the chat to give the assistant visual context alongside your text description.
