Draft alt text with Gemini, then edit before anyone else reads it
Alt text is for people who cannot see the image. A fluent sentence that invents a city, a brand, or a mood is worse than a short honest line. This page sends the image to Gemini and asks for visible facts only. The result lands in an editable box so you can delete guesses before you copy. There is no claim that the draft meets a specific accessibility standard or that every object was named correctly.
Why this is worth doing in the browser
Social captions reward invention. Alt attributes do not. The four styles stay narrow: short alt text, detailed description, social media description, and accessibility description. The instruction is the same across them: do not invent details that are not clearly visible. You still edit. Related tools include the image analyzer if you want a longer recap first, and the local image tools if the file should never leave the browser.
How to use the tool
Pick a style. Upload the image. Confirm it may be sent to Google Gemini. Generate alt text. Edit the draft in place, then copy or download TXT. Clear removes the session text and the file picker.
- Keep the sentence about what is visible, not what you wish the photo implied.
- Remove any name you cannot confirm from the pixels.
- Short alt text is usually one sentence.
- Do not upload photos of other people without considering cloud processing.
Privacy
The image and the draft travel through Google Gemini. DevNestro does not keep an alt-text archive. Logs should include token usage, not the description. This is cloud AI, not a local captioner.
