Blog Post Image Generator From Your Text
Paste your article and get images made for the passages that need them, placed in the text with a caption and alt text for each.
Paste a blog post, newsletter or guide. River reads it to find the passages where a picture would help a reader: a process that is easier to see than describe, a before and after, a scene that sets the mood. It creates an image for each and places it in the document straight after that passage, with a short caption and alt text for screen readers. You can also name the paragraph you want illustrated and River will work on that one alone.
Most image generators start from a prompt you have to write. This starts from your text, so each image is tied to what the passage actually says rather than a generic picture of the topic. River also skips passages where an image would only decorate, because a picture after every heading slows readers down. Each image comes with the description used to create it, so you can regenerate it in another tool or adjust it in the chat.
It is for bloggers, newsletter writers and small business owners who publish regularly and do not have a designer or the budget for stock photos on every post. Use it once the words are final, so the images match the finished text. Check every image before you publish, especially anything showing people, products or data. Generated images can get details wrong, and a chart or diagram must match your real figures.
When an image helps a reader
Images earn their place when they show something words struggle with. A sequence of steps, a comparison, the size of a change, or what a finished result looks like are all easier to take in visually. Decorative images that repeat the heading in picture form add scrolling without adding understanding. A useful test is to cover the image and ask whether the reader lost anything. If not, it is decoration, and one strong image beats four weak ones every time.
Take an illustrative café article about cutting food waste. The paragraph explaining that waste fell from 14 kilos in March to 6 by June suits a simple bar chart built from those two numbers. The paragraph describing two smaller croissant batches suits an illustration of two half-filled trays. The opening paragraph about why waste matters does not need an image at all. Picking the right passages matters more than making the images beautiful.
Alt text describes the image for people using screen readers and for anyone whose images do not load. Describe what the image shows and why it is there, in a sentence, rather than starting with image of. Skip alt text only for purely decorative images. Captions are read far more than body text by people skimming, so use them to state the point the image makes, such as waste fell by more than half in three months.

Common questions
How many images will it add?
As many as the article needs, which is usually one for every few hundred words at most, and often fewer. River places images only where they help a reader understand or remember something. If you want a specific number, or an image for a particular paragraph, say so in the chat and it will follow that instead.
Can I use the images commercially?
Check the terms of the service you publish under and your own policies, especially for advertising or products. Generated images can also contain mistakes, such as odd hands or text that is not quite readable, so review each one before publishing. For anything showing a real person, product or place, a real photo is usually the safer choice.
Can it make charts from my numbers?
It can make simple visuals from figures that are in your text, such as a before and after comparison. Check that every number shown matches your article exactly, because a generated image can misdraw values. For precise charts with several data points, ask River in the chat to build a proper chart from the numbers instead.
Why does it skip some paragraphs?
Because an image after every paragraph makes an article slower to read without making it clearer. River looks for steps, comparisons, results and scenes that are easier to see than to read. Introductions, opinions and transitions rarely need one. If you disagree with a choice, ask for an image on any paragraph you like.
What is alt text and do I need it?
Alt text is a short written description of an image, read aloud by screen readers and shown when an image fails to load. It makes your content accessible to people with visual impairments and helps search engines understand the image. Each image here comes with alt text you can paste into your blog or newsletter platform.
