Presenter portrait: a smiling man in a green T-shirt behind a podcast microphone

A young man sitting at a podcasting desk. He has a joyful expression, showcasing a broad smile. The man has voluminous, curly hair with hints of light brown highlights, and he is wearing a fitted green t-shirt. The scene should be bright and modern, featuring a sleek black microphone in front of him. Include a pair of professional headphones resting on the table beside the microphone. The background should be minimalistic with soft lighting. Use a color palette that combines warm tones with pops of green. The composition should be centered on the man, with the microphone and headphones as key elements.

Cut by deletion only, as the editing steps below suggest: the label line, the opening instruction to create a digital illustration and four phrases about mood and theme.

Behind the button

What happens after you click Generate

  • Your picture is encoded

    Your browser turns the file into text and sends it through our server to OpenAI. Keep it under 5 MB, because larger requests are rejected before the model sees them.

  • GPT-4o mini describes it

    The model is asked for a prompt covering style, composition, colors and key elements. In our tests it wrote about 120 words of flowing sentences rather than a keyword list.

  • You clean it up

    The answer can arrive with a bold label line and quote marks around it. Strip those, copy the rest, and edit it before pasting it into your image tool.

Why bother

Four jobs for a reverse-engineered prompt

  • Name a look you can see but not describe

    You know you like a reference, but not why. The description hands you the words for it, such as "softly blurred studio background" or "warm tones balanced with green", which you can reuse in your own prompts.

  • Check what a model notices

    If the description skips the thing you care about, an image model reading your own prompt will probably skip it too. That tells you which detail to state first and more plainly.

  • Keep a series on one look

    Pull the style sentences out of the description and keep them as a block you paste under every new subject. A channel whose thumbnails and scenes share a palette is easier to recognize in a feed.

  • Brief a person, not just a model

    The output is plain text, so it also works as a written brief for an illustrator or an editor: a neutral description of the reference that everyone on the project can read the same way.

Making videos rather than single images?

Pick the closest of Blipix's 39 art styles first, then add the leftover details from your prompt as image guidance. Try it on a 30 to 60 second video.

Editing the Prompt You Get Back

We ran the presenter portrait from our AI avatar page through this tool. The answer opened with a bold label, then a quoted paragraph that included lines like “sitting in front of a professional microphone on a sleek white table” and “the background is a softly blurred modern studio setting.” Accurate, but written for a person to read. Here is how to turn that kind of output into a prompt that works.

  1. Split subject from style

    Read the description and mark two halves: what is in the picture (a young man, a microphone, headphones on a table) and how it looks (soft studio light, white backdrop, green and warm tones). Keep them as separate blocks. Swap the subject block to make something new in the same look, or swap the style block to redraw the same scene differently.

  2. Cut the instructions to the model

    Phrases such as "create an engaging portrait" or "the overall composition should convey" tell the reader what to feel, not what to draw. Image models get little from them. Delete them and keep the concrete nouns, colors, materials and light sources.

  3. Match the format your tool prefers

    Newer models with large text encoders, such as Flux, cope well with full sentences. Many Stable Diffusion checkpoints were trained on short, tag-style captions and often respond better when you rewrite the description as a comma-separated list, most important terms first.

  4. Set the frame for where it will be used

    The description never mentions shape, so add it yourself: 9:16 for Reels and TikTok scenes, 16:9 for a YouTube thumbnail, 1:1 for a profile picture. Some tools take it as a parameter typed after the prompt, such as --ar 9:16; most have an aspect ratio setting next to the prompt box.

  5. Describe a style, do not copy a work

    Borrowing a general look, like soft watercolor washes or grainy 35mm film, is how styles spread. Feeding in a specific artist’s piece to clone it, or a real person’s face to recreate them, is where you run into rights problems. If you want a painted look for a video, a ready-made preset such as the watercolor style is the cleaner route.

OpenAI's GPT-4o mini, a vision model. It gets your picture plus one instruction: describe the image as a prompt for an AI art generator, covering style, composition, colors and key elements. Its answer is capped at 300 tokens, roughly 200 words.

Most likely the file is too big or in a format the model does not read. Keep it under 5 MB and use JPG, PNG or WebP; convert iPhone HEIC photos first. A JPG around 1,000 pixels wide gives the model enough detail.

Two per day, counted by IP address. The counter resets at midnight UTC, not at midnight where you live. Uploads that fail with an error do not use up a try.

Blipix doesn't save them. The image is passed to OpenAI for that one request and the answer comes back to your browser. The only thing we log is your IP address and the date, to enforce the daily limit.

No. It describes the image, and an image model reading that description makes something new with a similar subject, mood and palette. Think of it as a starting brief. You can test it with the models listed on our AI image generator page.

Yes, with some trimming. In Blipix's Preset template, the AI Image Guidance box takes up to 200 characters of instructions that apply to every scene. Paste the style half of your prompt there. The faceless video generator page walks through the rest of the setup.

That is a different job: a prompt describes how a picture looks, while a caption speaks to the people scrolling past it. Use the image caption generator for post text.

It will describe them, but image generators are poor at redrawing exact lettering and logos, so expect misspelled words in the result. Leave brand marks out of the prompt; reproducing someone else’s logo can also create trademark trouble.
