Features
Every barrier has an answer.
Aletheia is built around the most common ways digital content fails people with disabilities: missing alt text, image-only PDFs, broken page structure, and forms with no labels. Each feature is a direct response to a specific failure that should not exist in 2026.
Core capabilities
What ships at launch
These are the features available the day Aletheia is released. No "coming soon" here.
AI Image Descriptions
When alt text is missing or meaningless, Aletheia uses AI vision to describe what the image actually shows. You can opt in per image, or set a default for the session. Images are sent only with your explicit choice and are not retained anywhere after the description is returned.
Scanned PDF Reading and OCR
Image-only PDFs are the most common inaccessible document in education and government. Aletheia runs OCR locally to convert pictures of text into real, searchable, screen-reader-navigable content with proper structure.
Content Restructuring
Pages with no headings, no landmarks, no logical reading order, and no skip links are restructured into properly organized content. Headings are inferred from visual hierarchy. Reading order is corrected. Landmarks are added so screen readers can navigate.
Form Assistance
Forms with missing labels, broken tab order, unlabeled inputs, and ambiguous error messages are analyzed and presented with clear labels, logical structure, and explicit error guidance. Multi-page forms get a progress indicator that screen readers actually announce.
Multi-Format Output
Save accessible content as semantic HTML, downloadable tagged PDF, braille-ready text that pairs with BrailleBuddy, simplified plain-language versions, and audio description metadata for embedded media.
Local Storage Library
Every accessible version you create is saved on your device, organized by source, taggable, searchable, and always available without rescanning. Export the whole library at any time. Wipe it at any time. It is yours.
Specialized modes
Tuned for the places content fails most
Three high-stakes domains where inaccessible content blocks access to education, healthcare, and government services. These modes ship after the launch version.
Student Mode Roadmap
LMS URL recognition for Canvas, Blackboard, and Moodle. Materials are organized by course. Assignment due dates are tracked. Direct connection to BrailleBuddy converts the fixed materials into braille-ready output for blind students.
Healthcare Mode Roadmap
HIPAA-aware local processing for patient documents. Patient portal navigation assistance with labeled forms and announced steps. Medical document plain-language translation that preserves the clinical meaning while removing the jargon.
Government Services Mode Roadmap
Pre-loaded templates for the most-failed federal and state forms. Step-by-step guided navigation for benefits applications, tax forms, and licensing. Progress saving for multi-page processes so a stalled session does not erase an hour of work.
Privacy and security
The safest data policy is not having the data
Aletheia processes your documents on your device. The architecture removes most categories of risk because there is no central place where your content lives.
On-Device Processing
Documents are parsed, restructured, and stored entirely in your browser. They are never uploaded to a server. They are never sent to a third party. They never leave your device unless you explicitly export them yourself.
Local Storage Library
Your accessible versions are written to your browser's encrypted local storage. They persist between sessions on the same device. They do not sync to a cloud account. Clearing your browser data clears the library, just like any other browser-local data.
Optional AI Image Description
AI image description is opt-in per image, with an optional global default. Each image you choose to describe is sent to the AI service only for that one description, returns the text, and is then discarded. No image is retained for training or any other purpose.
No Cloud Storage, No Tracking, No Telemetry
There is no server-side document store. There is no analytics package logging your browsing. There is no telemetry pinging home with your usage. Account data limited to email and scan count is the only thing stored outside your device, and only for paid tiers.
Accessibility
The tool that fixes accessibility is itself accessible
If a tool that promises accessibility is itself inaccessible, the promise is broken before the work begins. Aletheia's interface meets every standard the tool helps people enforce.
WCAG 2.2 AA
The interface meets WCAG 2.2 AA across every screen. Contrast ratios, focus indicators, target sizes, and structure are tested, not assumed.
Keyboard Navigable
Every action is reachable with Tab, Enter, and Escape. No mouse-only controls. No drag-only interactions. Full keyboard parity is the floor.
Screen Reader Compatible
Tested with NVDA, JAWS, and VoiceOver. Semantic HTML where possible, ARIA where needed, live regions where state changes need announcement.
High Contrast Mode
A built-in high contrast theme that goes beyond the default and respects forced-colors mode in browsers that expose it.
Reduced Motion
Animations and transitions respect prefers-reduced-motion. Decorative motion turns off when users have asked for stillness.
Large Touch Targets
Mobile interactive elements meet a 44 by 44 pixel minimum. No tiny taps. No fat-finger errors on a keyboard you cannot use.
