Sigil Stay close to the document
Put editing, notes and review where they make sense: alongside the content.
Paperwork deservesa better workspace.
Sigil brings editing, annotation and signature workflows together around the document that matters.
A document rarely ends when you save it. Someone needs to read it, make a correction, leave a note or add a signature. The work continues around the page.
Sigil is Altovar’s space for that work. Its desktop app brings PDF editing and annotations close to the file. Its web workspace connects document storage, signature requests and the people involved.
For organizations building their own workflows, the public API and JavaScript / TypeScript SDK connect Sigil to existing applications. AI assistance adds another way to work with document content, under organization access controls.
