Where your files are processed
Files leave your device
We observed a file upload to robobraille.org.
A hosted service reached by email or a web form. The vendor's notice states that source documents are received on the RoboBraille reception server and handled by processing agents, that the conversion is entirely automated with no human interaction, and that the service runs on servers in Sensus's own data centre in Denmark. The file leaves your device, which is the fact this field carries.
What it does
RoboBraille takes a document and gives it back in a form somebody can actually use: contracted or uncontracted Braille in eighteen languages, MP3 or DAISY talking books, EPUB and Kindle e-books, or an accessible format such as tagged PDF, DOCX, HTML or plain text. You send the file by email or through a web form and get the result back, with no account needed. It is free for individuals, and institutions pay a subscription to run it under their own branding for their students and staff.
Best for: Individual users who need their own material in Braille, audio or a reflowable format and have nobody to ask, and universities and libraries that want a self-service conversion service for their users without building one. It produces Braille in eighteen languages and also returns audio, e-books and tagged PDF.
Worth knowing: It is a service, so the document is uploaded — the vendor's own notice describes source documents being received on their reception server, processed automatically and returned. That is the trade for needing no account and no software. Its accessible-format output is produced by conversion and OCR, so it is aimed at getting text out of an inaccessible document rather than at repairing a document that is already tagged: for a PDF with a structure problem rather than a text problem, this is not the tool. The institutional side is a different product from the free side, sold by subscription through Sensus rather than self-service, so a reader who needs it for an organisation should expect a sales conversation rather than a sign-up. And its Braille and audio quality depends on the source: the same limits that apply to any OCR step apply here. The free side has a condition worth reading: it is for individual, non-commercial users who are not affiliated with an institution obliged to provide support, such as a university, and institutions need a paid subscription. The vendor documents library and learning-management integration for the institutional side, which is a separate arrangement sold through a partner rather than a public API, so Programmatic access is not the right field to describe it.
Details, and where each comes from
Vendor statements, our own reading of their pages, and the things nobody has established yet, each answered separately. Where we have not confirmed something it says so rather than guessing, and a row nobody has established is greyed out.

What the redaction verdict rests on
From the vendor's own documentation, read 22 September 2026. Not tested by us.
“RoboBraille is an e-mail and web-based service capable of automatically transforming documents into a variety of alternate formats for the visually and reading impaired.”
What that does not establish: Recorded as `none` on absence: the service converts documents into other formats — Braille, audio, e-books, tagged PDF, Office formats, text — and nothing in its documentation describes removing content from a document. It transforms rather than edits. What it does not establish: what the converted output contains. A tagged PDF built from an untagged source is a new document, and neither the service nor this index makes any claim about hidden data carried across in the conversion; a reader treating it as a redaction step would be using it for something it does not describe.
What the vendor says
Claims are labelled rather than repeated as fact. Where we have checked something ourselves, it says so and shows when. Checked means we read the vendor's own page and it says what we recorded — not that we tested the behaviour, unless the note says we did.

How we checked: Read as rendered text in headless Chrome on 2026-10-01 and saved to the evidence archive, so the read can be repeated against the same file. Comparison ignores case, punctuation and hyphenation, which is why "open-source" on the record matches "open source" on the page.
