Delta Echo / Writing on X
Echo learns from your existing writing and saved edits to help new drafts start closer to how you actually write. Bring the idea, then make the final words yours.
Your writing → Voice → draft → your edit → publish or schedule.
Shipped this too early. Took me about a day to realize it.
We removed a feature after nobody used it for a week.
Shipped a feature last week. Nobody used it.
Removed it today. Should have asked whether anyone needed it first.
Next time I’m asking before I build.

Start with your writing
“Make it casual” leaves a lot unsaid. Your sentence rhythm, word choices, and way of making a point come from actual writing. Echo keeps that context in Voice for the next draft.
01 / Connect
Connect your X account. Echo automatically looks for up to 10 recent original posts, excluding replies and reposts, and analyzes their writing patterns. If no usable writing is found, retry or add your own writing samples during onboarding.
02 / Make it yours
Fine-tune Casual ↔ Professional, Friendly ↔ Direct, Short ↔ Detailed, and Safe ↔ Bold. Add writing guidance and choose your topics.
Your saved analysis and examples stay available across drafts. You can analyze your writing again.
03 / Keep editing
Saved edits to generated posts become examples for future Posts. Edits to generated replies guide future Replies.
The shared Voice sets the direction. Your review decides what is ready to publish.
Write in your own style
Posts
Give Echo an idea and context, or generate from your topics. Voice guides the draft. Edit the wording, rewrite it, or write from scratch.
Publish now, choose a specific time, or use your next recurring slot. Scheduled posts publish automatically. You can edit or reschedule queued posts and pause autoposting.
Replies
Echo uses the same writing analysis, controls, and guidance to draft replies to fresh posts from authors you choose. The original post provides the context.
Review and edit the reply in Echo, then open the prefilled X composer. You finish publication in X.
Is it for you?
You are a founder or individual writer with something to say on X. You want help drafting in your Voice and a place to revise and schedule. You bring the ideas, review the output, and decide what gets published.
Echo is a paid workspace that requires X setup. It currently supports link-free text, with monthly usage limits. If you need a free one-off generator, media publishing, or thread scheduling, it is not the right fit.
Simple starting point
Posts, Replies, Voice, and scheduling on every plan.

When you connect a new X account, Echo starts analyzing up to 10 recent original posts, excluding replies and reposts. It saves writing patterns and examples as your Voice. You can adjust four style controls, add writing guidance, choose topics, and run the analysis again.
If the initial analysis cannot find usable public writing, onboarding lets you retry or paste up to 10 representative writing samples. Choose original writing that reflects how you want to sound. You still need to connect your X account.
Saved changes to a generated draft become examples for later drafts of the same type. Post edits guide Posts, and reply edits guide Replies. This does not guarantee a closer match every time. Review the wording and facts before publishing.
Echo is a paid writing workspace, starting at $19/month. It keeps your Voice, drafts, and schedule together. If you only need one free tweet with no account setup, that is a different workflow.
