What has already been built
Substr is already much further along than a landing page and a pitch. Communities exist, threads are live, people can join corners, post in different formats, save things for later, tune the interface, and manage spaces with more intention.
This page is here so visitors can see that progress instead of guessing. It is not a promise board. It is a public snapshot of what is already real.
Discussion, Link, Media, Poll, Q&A
Bookmarks and collections are live
Recent polishing has been mobile-first
Built before monetization, shared in public
Community foundations
Substrs can be created, managed, moderated, joined, and shaped into spaces with their own identity and structure.
New conversation formats
Posting is no longer just one flat thread type. Substr already supports richer community-native formats.
Personal utility
People can keep track of what matters to them instead of losing good threads inside moving feeds.
Recent product milestones
Account and signer flow
Multi-account handling became more understandable, faster to switch, and better aligned with the mobile experience.
Polls
Substr now supports polls as a real post type instead of treating everything as generic discussion.
Q&A
Question posts now feel different from ordinary threads, with answer-driven UI instead of one flat reply stream.
Saved and collections
People can save posts for later and organize them into named collections without making the flow heavy.
Appearance and theming
The customizer has grown into a real product layer, with better persistence and more account-aware behavior.
Mobile polish
A lot of recent work has focused on making Substr feel intentional on phones instead of merely usable.
What this means
Substr is being shaped as something slower, more intentional, and more community-first than the usual social feed. That does not happen through one big launch. It happens through steady product work, testing, refinement, and a lot of small decisions that improve how the platform feels.
The goal is still the same: keep Substr free to use, light on noise, and aligned with a more open internet. This page simply makes the progress visible.
What we are refining now
Still early, already real
Substr is still early, but it is no longer just an idea. The community layer, posting system, personal utility, theming, moderation flow, and mobile experience are all being actively shaped into something people can actually use.
