AltGen

AltGen is a bulk and individual alt-text generator for teams that need accessible, search-friendly image descriptions. It suits accessibility, content, ecommerce, and development workflows that need multilingual output and ways to move results into existing systems. Its generous input options and automation controls make it a strong operational tool, while the 26-credit free allowance is mainly an on-ramp rather than a production quota.

Overview

AltGen accepts uploaded files, image URLs, CSV imports, or images discovered by its page scraper. That range is useful when a library is split between local files, spreadsheets, and live pages; you can bring each source into one workflow instead of preparing everything manually. Individual generation is available when only a few images need attention, while batches can contain up to 5,000 images for larger catalogues or site migrations.

Descriptions can be shaped with an industry preset, writing style, and target languages. AltGen supports up to 30 languages per image, so it is better suited to multilingual publishing than a tool limited to one output language. Generated text can be reviewed and edited in the dashboard before CSV export, giving editors a checkpoint between generation and publication.

Key features

• Multiple intake methods: Upload files, paste URLs, import CSV data, or scrape a page for images. This covers common starting points for content teams and developers.
• Large batch size: Up to 5,000 images per batch supports sizeable libraries, although your monthly credits still determine how much you can process.
• Multilingual and configurable output: Up to 30 languages, industry presets, and selectable writing styles help align descriptions with regional publishing requirements and brand conventions.
• Review and export: Dashboard editing and CSV export are practical for human approval and for handing finalized text to another publishing system.
• Automation interfaces: A REST API and webhooks can send results into your stack. Workspace-scoped API keys, optional expiry, and dashboard revocation provide useful control when credentials are shared across integrations.
• Privacy and account controls: AltGen says submitted images and generated content are not used to train AI models. After account deletion, personal data and generated content are deleted within 30 days, except records required for legal or accounting reasons. Passwords are hashed, payments are handled by Stripe, and cookies are limited to sign-in and account protection.

Pricing

The Free plan includes the core workflow and automation features, but 26 credits per month will constrain regular bulk production. Pro raises the allowance to 2,000 credits for $29 per month, making it the practical tier for ongoing team workloads; the appropriate consumption depends on how credits map to your image volume. Organizations needing larger limits, identity management, service commitments, or branded delivery must request custom pricing. Dedicated support is associated with the custom plan, while the site provides [email protected] as a contact address.

Platforms

AltGen is offered through a web interface and an API. The web dashboard handles intake, review, editing, and export; the REST API and webhooks are the route for embedding generation and result delivery in other systems.

Who it's for

The Free plan is appropriate for an individual evaluating multilingual alt-text workflows or processing occasional images. Pro is aimed at growing teams that need recurring batches, shared operational access, and integrations without negotiating a bespoke contract. The custom tier fits organizations with high volume, custom connectors, SSO, team administration, white-label delivery, or a formal SLA. AltGen is less compelling for a small user whose needs fit comfortably within a very low monthly allowance and do not require API or webhook automation.

Pros and cons

Pros

• Flexible image intake reduces preparation work across files, URLs, CSVs, and scraped pages.
• Up to 30 languages per image supports international publishing from one workflow.
• 5,000-image batches plus API and webhooks give teams a path from manual jobs to automated pipelines.
• Review, editing, and CSV export preserve an editorial approval step before publishing.
• Scoped, revocable API keys and stated non-training use address common integration and content-governance concerns.

Cons

• The free allowance is only 26 credits per month, so sustained or catalogue-scale use quickly points to Pro.
• Advanced organizational controls are reserved for custom pricing, adding a sales step for SSO, team management, custom SLAs, or white-label needs.
• Pro is a monthly commitment at $29, which may be more than occasional users need when cheaper, narrower tools are sufficient.

Alternatives

Altagonist is a lower-cost option when 50 credits and up to 50 alt tags per month on its Free plan are enough, with Windows support and 70 languages; its Personal plan is €5 per month billed annually.

ALTtext.org suits readers wanting a browser extension, iOS, and macOS coverage alongside web access, with a free allowance of 20 ALT texts per day.

AI Alt Text Builder is worth choosing when a low-cost web tool and an optional own OpenAI API key are preferable; its free tier provides 25 tokens.

Alt Text Pro offers a $0 per month tier with 15 credits plus 150 signup credits that never expire and includes a WordPress plugin, making it appealing for WordPress-focused, low-volume work.

AltText.io is an alternative for API, extension, and web users who need batch processing and advanced SEO; its Silver plan is $19 per month for 600 image credits.

AltTextAPI is better for a simple API-first setup: its free plan includes 50 images per month in English, while Pro is $9 per month for 1,000 images.

AltTextLab is a lower-priced choice when 25 monthly credits, 20-plus integrations and API access, and more than 130 languages matter more than AltGen's intake and review workflow.

Verdict

Choose AltGen if you need multilingual alt text at scale, editorial review, and API or webhook delivery in one workflow. Its strongest case is the combination of broad image intake, 5,000-image batches, and configurable language output. Look elsewhere if your workload is occasional, your budget is below $29 per month for regular use, or you need enterprise controls without moving to custom pricing.
