Free beta
Drafts for X, in your own voice.
Starling writes replies, quotes and posts on X the way you write. On your computer, press the Starling button on a post and the draft appears in X's own reply box. On your phone, paste the post and copy the draft into the X app. Either way, you press Post yourself.
It learns your voice from writing samples and from your own posts, when you ask it to. It never posts, likes, follows or messages anyone for you.

About this recording
It shows the real extension and website, recorded before launch. The X page in it is a stand-in copy and the AI's words are scripted, and the film says so on screen. A recording on the real X site is coming.
How it works
You stay in charge of every post
You use X as usual. Starling adds a button to each post and to X's composer, writes a draft in your voice, and leaves posting to you.
-
Install and connect
Add the Chrome extension and create an account. Before anything is sent, the extension shows what it shares and asks first.
-
Press the Starling button
On a post, one press drafts a reply or a quote. In X's composer, the same button drafts a new post or tightens a rough one.
-
Review and edit
The draft appears in X's own text box, where you change anything you like. A side panel helps with what to post.
-
Post it yourself
Starling never presses Post, Reply or Schedule. The extension refuses to click those buttons, and automated tests check that it does.
-
Teach it your voice
Writing samples and short notes shape later drafts, and one press on your own X profile adds your posts as samples. Learning while you browse is a separate choice, and it is off until you turn it on.
Screens from before launch

On your phone
Works with the X app
Chrome extensions don't run on phones, so Starling has a writing page that works in your phone's browser, with the same account and the same drafts.
-
Open the writing page
Go to app.starlingwriter.com/write and sign in. Add it to your home screen and it opens like an app: on iPhone, Share then Add to Home Screen; on Android, the menu then Install app.
-
Give it the post
In the X app, tap Share then Copy link, and paste it in. Starling reads the post for you. On Android you can share the post straight to Starling.
-
Get your draft
Tap Write it. The reply comes back in your voice. Tap Reply on X and the X app opens with the draft ready, or copy it.
-
Post it yourself
Change anything you like in X, then press Post. Starling never posts for you.

Questions
Common questions
Does Starling post for me?
No. It writes a draft into X's own text box. You read it, change it and press Post yourself. It never posts, likes, follows or sends messages.
How does it learn my voice?
From writing samples and notes you give it, and from your own posts when you press the button on your own X profile. Learning while you browse is off unless you turn it on.
When can I use it?
Now, on your phone: create your free account and open the writing page. The Chrome extension for your computer arrives when the Chrome Web Store approves it. Follow the launch on X to hear first.
What do I need?
An X account. On a computer, desktop Chrome with the Starling extension. On a phone, the Starling writing page at app.starlingwriter.com/write: paste the post or its link, get the draft, and open it in the X app. You can add it to your home screen like an app.
Is Starling part of X?
No. Starling is an independent product and is not affiliated with or endorsed by X Corp. You are responsible for what you post, and X's rules apply to every post.
