Free AI Image Describer

How it works

Add one image or a whole batch. The tool reads each file locally in your browser and passes it to the AI that ships inside Chrome. There is no upload step because there is no server that receives your pictures.

For each image it writes a description of who or what is in the frame, where things are, what is happening and which text is visible. You can ask for a short two-sentence summary or a more detailed paragraph, and switch the output language.

Descriptions are drafts. Click any result to edit it, copy it, or add alt text and hashtags from the same pass if you also need them. Nothing is saved anywhere except in your own browser.

The first time you use it, Chrome downloads its on-device AI model. The download size varies, and Chrome needs about 22 GB of free disk space to install it. The model is shared by every site that uses it, so you only set it up once. It needs desktop Google Chrome (Windows, macOS, Linux or ChromeOS) with its built-in AI available. Phones and other browsers are not supported yet.

What the image describer does

• Writes a full description of each image: subject, setting, actions, colours and any readable text.
• Short or detailed length, so you can get a caption-sized summary or a paragraph.
• Optional alt text and hashtags from the same run if you want all three.
• Output in English, Spanish or Japanese.
• Add a line of page context to steer the wording toward what matters for your page.
