Roadmap
What's coming
One schema running on desktop, browser, and phone, and over 1,400 commits since April. This is what is in flight, and where it goes after.
Working on now
Mobile catching up to the desktop app.
Mobile parity
Home, Library, Notebook, the reader, courses, annotations, and import are all built on iOS and Android. Spaced review, the connection graph, and the wikilink picker are not there yet, and Journal and Chat are empty on every platform. Closing that gap is the current work.
Where this goes
None of it is in the app today.
Sync and accounts
Local SQLite stays the source of truth, with a server as the shared authority between devices. Architecturally settled, entirely unbuilt, and the first thing that will ever cost money.
AI and chat
No part of this exists today — no prompts, no model, no server. What does exist is the part that is expensive to retrofit: every review is stored as a transition stamped with the scheduler parameters that produced it, highlights carry an anchor-provenance record, notes are readable files, and one schema runs on desktop, browser, and phone. The hard part is not the model. Anything that reads a personal library either runs on the machine holding it or sends it elsewhere, and that decision is not made.
PDF sources
PDFs as first-class sources, each page becoming readable, highlightable text. A prototype exists on a branch; nothing has merged.
Read-aloud
Narration that would run on the local machine, with no audio leaving it and no account involved. Also a branch prototype.
Domains and quick capture
Spaces for a topic or subject, and a fast way to get a thought into the vault without deciding where it belongs first.
Journal
A dated surface for reflecting on what you have been learning. The screen exists as a placeholder on desktop and mobile, with nothing behind it.
Browser extension
Saving the page you are on without copying its address first.
Plugins
A way for other people to extend Piper.
Nothing here carries a date. A month on any of these would be a guess dressed up as a plan.
For what has already shipped, see what's new. For what a paid tier will eventually cover, see pricing — sync is the first thing that will ever cost money.
