Alt Text Guru — an accessibility-first alt-text assistant for web designers
Alt Text Guru is a focused tool that generates concise, context-aware alt text and editorial guidance for images used on the web. It prioritizes active voice, the fewest words needed to convey meaning, and SEO-friendly phrasing while avoiding superfluous prefixes like "image of" when context already makes the media an image. The design purpose is to make alt text consistent, auditable, and easy to integrate into editorial and engineering workflows: for simple photos it emits one-line alt attributes (e.g., "Woman jogging along a lakeside path with a golden retriever"), for complex visuals it pairs a short alt with a structured long-description summary and suggested link text (e.g., short alt: "Bar chart: 2024 Q1 sales up 15%" plus a long description that lists exact values and axis labels). Alt Text Guru also enforces style templates (e-commerce, news, editorial, social), flags decorative images and suggests an empty alt (""), and offers batch/CSV processing so teams can apply consistent rules across hundreds of images. Example scenarios: 1) An e-commerce team uploads a product catalog and receives optimized, SKU-aware alt lines ready for the CMS; 2) AAlt Text Guru functions news desk publishes a data-driven explainer and receives a short alt plus a recommended longdesc that captures the chart’s key takeaways and numeric values.
Core functions and real-world application
Generate concise, context-aware alt text
Example
"Red leather ankle boot, side view, stacked heel"
Scenario
A product photographer uploads photos of shoes. Alt Text Guru reads product metadata (name, color) and produces a short, SEO-friendly alt that can be pasted directly into the product page’s <img alt=> attribute, keeping mobile screen-reader users informed without verbosity.
Batch processing and style templates (consistency at scale)
Example
"[SKU12345] Black cotton tee, front view" applied across 1,200 SKUs
Scenario
During a site migration, a retailer exports an image CSV. Alt Text Guru applies an 'ecommerce product' template that pulls title, color, view type, and SKU, then returns a CSV of prefilled alt texts and a report of items missing critical metadata so editors can prioritize fixes.
WCAG-aware guidance, long descriptions for complex visuals, and editorial checks
Example
Short alt: "Line chart: monthly active users, Jan–Dec 2024"; Long description: "Monthly active users rose from 12.1k in Jan to 28.7k in Dec; three seasonal dips in April, July, October; axis labeled 'months' and 'users (k)'..."
Scenario
A news organization publishes interactive data visualizations. Alt Text Guru produces a short alt for the visual element and a separate, detailed long description suitable for a linked 'Full data description' page, plus a QA checklist that confirms color contrast notes and stated data sources for accessibility reviewers.
Primary user groups and why they benefit
Web designers, front-end developers, and design systems teams
These users need consistent, concise alt text that fits component libraries and responsive patterns. Alt Text Guru speeds handoffs from design to code by producing ready-to-use alt strings, offering templates for hero images, thumbnails, and responsive srcset variations, and exporting CSVs or CMS-ready payloads. Designers use it to document accessibility guidance in pattern libraries; devs use it to automate alt injection during builds or data migrations.
Content editors, product managers, accessibility teams, and SEO specialists
Content and product teams need to meet WCAG requirements, reduce legal risk, and improve discoverability. Accessibility teams use Alt Text Guru to audit existing assets, generate compliant short alts plus long descriptions for complex visuals, and produce remedial content at scale. SEO specialists benefit from succinct, keyword-aware phrasing that improves image search. Product managers and editors use the tool to create editorial rules, train writers on alt-text best practices, and to produce reporting that tracks coverage and outstanding accessibility gaps.

Alt Text Guru — Q&A
What is Alt Text Guru and who should use it?
Alt Text Guru is an AI tool that generates concise, active-voice alt text optimized for accessibility and SEO. Ideal users include web designers, content editors, e-commerce managers, accessibility auditors, and social media managers who need consistent, screen-reader-friendly descriptions quickly.
How do I give the tool enough context for accurate alt text?
Provide minimal but focused context: the image role (hero, thumbnail, logo, chart, decorative), the target audience, the page intent (inform, sell, illustrate), and an optional SEO keyword. Example: 'Product detail page — female running shoe, blue, 8.5, keyword: "women's running shoe"' leads to a targeted, SEO-aware alt like 'Blue women's running shoe, size 8.5'.
How does it handle decorative images and complex visuals?
For decorative images, set the decorative flag so the tool returns an empty alt attribute (alt=""). For complex visuals (charts, infographics), request a short alt summarizing the purpose plus an optional longer description (caption or aria-describedby) that contains full data or insights. The tool can suggest both the short alt and a linked long description.
Can Alt Text Guru produce SEO-friendly alt text without hurting accessibility?
Yes—by prioritizing relevance and brevity. The tool inserts keywords sparingly and only when they describe essential content. Best practice: keep descriptions factual, avoid keyword stuffing, and ensure the alt complements (not duplicates) visible text. Example before: 'image of red mug on table'; after: '12oz red ceramic coffee mug on white table'.
Is my data private and what formats/batch features are available?
Alt Text Guru is privacy-focused: images are processed transiently and not retained after the session. Avoid uploading sensitive personal information. Commonly supported formats include JPEG, PNG, WebP, GIF, and SVG; batch upload and CSV/JSON export simplify large-site workflows. Check the site for exact file-size limits and integration options.
