echooo is a calm place to write—and a public place to read.

Writers draft in Workspace. Readers discover chapters in Resonance. AI is here for momentum, not replacement.

Principles

Protect flow. Invite imagination.

echooo stays quiet while you write, then helps you share finished chapters when you want an audience.

Highlight

Intentionally Quiet

echooo stays quiet while you’re writing: clean typography, fewer distractions, and blocks that let you keep momentum without losing structure.

Highlight

The Shadow Writer

I designed the AI to be a partner, not a replacement. It acts as an extension of your mind—quietly unblocking thoughts or echoing your rhythm, but never speaking until spoken to.

Highlight

You Steer, It Rows

I draw a clear line: You define the taste and direction; echooo provides the momentum. It never hijacks your voice—it only amplifies the rhythm you set.

Highlight

Resonance, Shared

When a chapter is ready, publish it to Resonance. Readers see a read-only snapshot and can leave kudos on the lines that hit — republish keeps kudos on unchanged blocks.

FAQ

Quick answers.

If you’re unsure about something, start here—then the rest is best learned by writing and reading.

Where does my writing live? Is it safe?

Your drafts are saved to the cloud, encrypted at rest, and protected by Cloudflare’s infrastructure. I built this to be a sanctuary, so I treat your data security with the same paranoia I treat my own.

Is echooo free?

Currently, yes. We are in a Public Test phase where my priority is polishing the UX, not making money. You can use the built-in AI for free (subject to a generous 5-hour sliding window quota to keep the servers from melting).

Am I locked in?

Never. Your words belong to you. You can export to Markdown at any time. Whether you want to move to Obsidian, VS Code, or just keep a local backup, the door is always open.

Is this like Notion? Do I need to learn 「blocks」?

It’s block-based, but not that kind of block-based. No databases, no kanban boards, no complexity. I designed a simplified block system solely for writing—so you can rearrange paragraphs easily without fighting the UI.

Can I use it offline or on multiple devices?

echooo is currently a web-only experience, so you’ll need an internet connection to write. The upside is that your library syncs automatically—log in from your laptop, desktop, or tablet, and your drafts are always right there.

Which model do you recommend?

I personally recommend Gemini 2.5 or 3 Flash. In my experience, it simply performs the best within echooo—it feels snappy and natural. Gemini 3 Pro is undeniably powerful, but it is significantly more expensive. Flash is the sweet spot.
