AI alt text generation for image SEO and accessibility
Computer vision analyses each image and produces a concise, human-readable description in the output language you select.
A free crawler inventories your pages and shows exactly which images are missing alt text before you start fixing them.
WordPress, WooCommerce, Shopify, BigCommerce, Magento, Contentful, DatoCMS, Storyblok, Webflow, Cloudinary, Dropbox and Google Drive connectors write alt text where your content already lives.
Process entire media libraries at once or trigger generation automatically on upload, with saved defaults per project.

Structured annotation, curation, model evaluation and human-in-the-loop review across vision, language and generative tasks, used to build the training and eval data behind production models.
Recursion agents start on their own from builds, alerts, commits, checkpoints and schedules, then work in the background until the task is finished and reviewable.
Specialist agents cover software engineering, reliability, security, ML research, evals, R&D, product and finance workflows, from flaky test fixes to postmortem drafts and vulnerability patches.
Every agent run is scored by a grader, and graded sessions leave memories, notes and skills that the next session reads before acting, so quality compounds over time.
SpecialistStreamlines end-to-end computer vision workflows from annotation to model deployment, but lacks Labelbox's general enterprise agent orchestration.
