AltGen
What it is
AltGen generates accessible, SEO-ready alt text for individual images or batches of up to 5,000. Images can be uploaded, supplied by URL, imported from CSV, or found on a page with the built-in scraper. Descriptions can be produced in up to 30 languages per image and adjusted using an industry preset, writing style, and target languages. Users can review and edit results in the dashboard, then export them to CSV. A REST API and webhooks provide ways to send results into a user's stack, and API keys can be scoped by workspace, given an optional expiry, or revoked from the dashboard. AltGen is available on the web and offers a free plan with 26 credits per month. The Pro plan costs $29.00 per month and includes 2,000 credits per month. Both plans list all languages, bulk upload, CSV import, page scraping, API access, webhooks, and an image library. A custom plan has pricing based on needs and lists higher volume limits, custom integrations, dedicated support, a custom SLA, SSO and team management, and white-label options. AltGen says it does not use submitted images or generated content to train AI models.
