No technical knowledge required.

Powered by
// The Workflow

Three steps.
Zero complexity.

No infrastructure setup. No coding required. Upload your data and PromptMax handles the rest — at any scale.

01 /

Upload Data

Prepare a CSV with the data you want to process — one item per row. Upload it to PromptMax in seconds. Your file is stored securely and processed privately.

02 /

Configure Prompt

Give your job a name, write your instructions in plain English — tell the AI exactly what to do with each row — and choose your model. Sensible default values are pre-filled so you can get started straight away, even if it's your first time.

03 /

Download Results

PromptMax processes your entire batch automatically in the background. Log back in to check your dashboard when you're ready — your completed CSV with AI-generated responses matched to every row will be waiting, ready to download and use straight away.

// Capabilities
