  • Privacy Concerns
    Despite efforts to anonymize feedback, there may still be concerns about data privacy and the potential for identifying anonymous contributors.

Questions & Answers

As answered by people managing Matter and Postilae.

What makes your product unique?

Postilae's answer:

Postilae is a single container for the whole lifecycle of a reading-based project. Most tools cover one slice — a reference manager, a note app, a PDF annotator, a word processor — so your sources, quotes and drafts end up scattered. In Postilae you import PDF, EPUB and DOCX sources, annotate and highlight them, capture quotes with auto-formatted citations (MLA, APA, Chicago), connect ideas on a mind map, track milestones from research to submitted, and export a Word-ready draft — without leaving the workspace. Everything is private by default: your library stays on your device, and optional cloud sync is end-to-end encrypted with a passphrase only you hold.

Why should a person choose your product over its competitors?

Postilae's answer:

Because it replaces a fragmented stack (reference manager + note app + annotator + word processor) with one continuous workflow, so a highlight you make while reading is already linked to the quote, the idea and the project chapter it belongs to — no re-typing, no copy-paste archaeology. It also has a genuinely comfortable reader (reflowable text, dual navigation, page-flip thumbnails, bookmarks, in-page search, pinch-zoom, three calm themes) instead of treating reading as an afterthought. And privacy is structural, not a policy promise: sync is encrypted client-side, so nobody — including us — can read your library.

How would you describe the primary audience of your product?

Postilae's answer:

Researchers, PhD and graduate students, academics, writers and serious non-fiction readers — anyone who reads a lot of long-form sources and has to turn that reading into something: a thesis, a paper, an essay, a book, a report. It also fits self-directed learners who want their reading to accumulate into structured knowledge rather than a folder of forgotten PDFs.

What's the story behind your product?

Postilae's answer:

The name comes from postillae — the marginal glosses medieval readers wrote beside a text. That's the idea: the value of reading lives in the margins, in what you note, question and connect. Postilae started from the frustration of a scattered workflow — annotations in one app, citations in another, the actual writing somewhere else, and half the thinking lost between them. It was built to keep reading, annotating and writing in one calm, private space, from the first source to the finished draft.

Which are the primary technologies used for building your product?

Postilae's answer:

React 19 with TanStack Start and TanStack Router, TypeScript, Vite 7 and Tailwind CSS on the frontend; pdf.js, epub.js and docx for reading and exporting PDF/EPUB/DOCX; IndexedDB for local, offline-first document storage; Web Crypto (AES-GCM-256) for client-side end-to-end encryption; and a Postgres backend with row-level security for accounts and encrypted sync. Deployed as a PWA on an edge runtime.
