RESEARCH · EDUCATION

Read and annotate on your own machine.Keep the data in a place you can name.

Sigil opens, searches, annotates and redacts PDFs locally, and signs with your own certificate. Altovar Cloud holds the data in named regions. Auris signs your institution in, and Osprey publishes what you find.

IN THE PRODUCT

Four things you can check.

SIGIL
Desktop

Windows and Linux. PDFs are opened, searched, annotated and redacted on your own machine.

OCR
Tesseract

OCR works when Tesseract is installed on the machine. Without it, Sigil does not offer OCR.

STORAGE
S3 API

Object storage speaks the S3 API, from 250 GB to 5 TB. Storage Box covers the rest.

PEOPLE
SAML · OIDC · SCIM

Auris connects to the institution's identity provider and provisions accounts from it.

THE SITUATION

How research IT usually breaks.

The tools are fine. The seams are the problem.

Documents travel by email
A paper goes round with comments in five different files. Nobody can say which copy is the one that was signed.
Data lives where a student left it
A dataset sits on a laptop or in a personal cloud folder. When the person leaves, so does the only copy.
Access follows the person, not the project
Accounts are made one by one and removed when someone remembers. A directory-driven login fixes both ends.

THE PIECES

Four pieces, each with its own page.

Documents, data, people and publishing.

01 PDF

Sigil

PDFs on your own machine

Open, search, merge, split and annotate. Redaction removes the pixels underneath. Password protection uses AES-256. Sign with your own certificate; the check reports whether the file is intact.

Open Sigil
02 HOSTING

Altovar Cloud

Storage and servers in named regions

S3-compatible object storage, Storage Box, VPS, dedicated servers and managed databases. The region is shown on each order.

Open Altovar Cloud
03 IDENTITY

Auris

One login for the institution

SSO through SAML or OIDC, SCIM provisioning, custom roles per project, and an exportable audit log.

Open Auris
04 CMS

Osprey

Publish what you find

A headless CMS with a schema written in code. Public content is readable without a key, over REST, read-only GraphQL or a typed SDK.

QUESTIONS

Questions we get.

Do you offer GPUs or managed notebooks?

No. We do not offer GPU servers or a managed notebook environment.

Does Sigil run on a Mac?

No. Sigil is built for Windows and Linux.

Is a Sigil signature a qualified signature?

No. It is a PDF signature made with your own certificate. There is no trust store, revocation check or timestamp, so it is not an eIDAS qualified signature.

Can we keep data out of third-party services?

Sigil works on your machine. The cloud products run in the regions shown at order, and some network services in front of them run on a global network. Ask us for the data map of the pieces you want.

Can it handle thousands of accounts?

Auris provisions through SCIM from your identity provider, so accounts follow your directory. We have not published a load figure for it.

WHAT THIS PAGE DOES NOT PROMISE

No macOS

Sigil is built for Windows and Linux.

No qualified signatures

Sigil signs with your own certificate. It is not an eIDAS qualified signature.
