AI Alt Text Generator (Bulk)

Set the CSV format to 'Shopify Alt CSV', upload your product images, enter target keywords, run the generator, download the generated CSV file, and import it directly into your Shopify admin panel to update your product listings in bulk.

It compiles a standardized CSV containing image file titles, alt texts, and descriptive captions. You can import this CSV into WordPress using any bulk media metadata importer plugin to automatically associate alt texts with media library attachments.

Standard mode focuses on concise visual summaries under 125 characters, which is ideal for e-commerce and standard web pages. Descriptive mode generates detailed, multi-sentence summaries (up to 250 characters) designed for complex infographics, charts, and highly detailed visual art.

By specifying target search terms, the AI naturally weaves these keywords into the generated alt text without keyword stuffing. This helps search engines index your images for relevant search queries while maintaining accessibility.

No. All file processing runs locally in your browser memory. Your images are never uploaded, stored, or processed on our backend servers, guaranteeing complete privacy for sensitive product catalogs or personal photos.

No. The API connections run client-side to public developer pipelines. Your uploaded media assets are not used for public training of models, keeping your intellectual property safe.

The tool is 100% free with no login or subscription required. You only need to configure your own Gemini or OpenRouter API key in the settings panel to power the vision analysis.

Most screen readers for visually impaired users stop reading alt text around 125 characters. Keeping text concise ensures compatibility with accessibility tools while satisfying search engine guidelines.

Check that your API key is correctly copied without extra spaces and has active billing. If you are uploading a large batch of heavy images (e.g. over 50 files), process them in smaller batches to avoid browser timeout limits.

Vision AI can occasionally misinterpret abstract or highly blurred graphics. You can manually edit any generated text directly in the interactive results table before downloading your CSV export.
