Quillium Is Now in Public Beta

Huge thanks to our private beta testers!

After ~4 months of work, Quillium has finally achieved public beta stability! It could not have gotten to this point without countless rounds of testing and feedback from private beta testers—Nicole Chin, Evan Zhou, and many others—it’s ready for the world.

As a writing app, I know that stability is paramount and any data loss is a total catastrophe. Actually, half of the months spent was on reliability and predictabilty alone: it’s that crucial to what we do.

That being said, this is still in beta as features may change any time.

What is Quillium?

Quillium is a prose editor built around one idea: revisions are the actual work of writing.

Most writing tools assume you know where you’re going. You don’t. You write a sentence, rewrite it three different ways, and lose two of them.

Quillium lets you fork your prose the way a programmer forks code. Every version stays alive. You navigate between them, compare them, and converge when you’re ready. No more draft_v3_FINAL_REAL.docx.

What “public beta” means

This means the core is stable. You can use Quillium for real writing today like branching, writing, commenting, and navigating your revision history. We’ll keep shipping improvements, but the foundation is solid.

If something breaks, we want to hear about it. That’s why it’s a beta.
