Threaditor v2: building the best thread editor


10 min read

The centerpiece of ThreadStart is with no doubt it's powerful thread editor. The all-new version 2 has finally arrived. Before, only beta testers and then Pro subscribers had access. Now, the brand new editor is available to all. Yay!

Here are the major improvements arriving with the new version.

Writing Experience

One of the biggest changes happened under the hood. A complete rewrite of how the editor takes the text and converts it into a thread.

While this change isn't visible, it provides a much smoother writing experience. And, it allows the user to have common text editing features directly in the editor, like lists and images.

The new thread editor makes it easy to spot where tweets end and new ones begin.

It also makes it possible to distinguish separate tweets easier. The new editor shows you horizontal lines between tweets. Before, it could be hard at times to know exactly where one tweet stopped and the next one began. Now, you will immediately know.

(For the technically interested: the biggest change was moving from a textarea to a contenteditable div. This makes it possible to put other DOM elements within the editor.

This might not sound like a big deal. But it is. In a regular textarea you can really only put text. No lists. No images. Only plain text. With contenteditable you can put any HTML into the editor.)

Media Management

Managing images and videos is much easier now. In the new editor, you can quickly add new media by either

  • selecting the image icon, which opens your local files

  • dragging and dropping an image into the editor or by

  • copy & pasting it directly into the editor

Add and move images between tweets.

ThreadStart takes care of uploading & storing your files. The files will remain visible in the editor as well. If you want to move them to another tweet, it is as easy as dragging them there. That's how simple managing your Twitter images should be!

Preview & Snippets

When you write a thread, you want to know how it will look once it gets posted to Twitter. For this purpose, ThreadStart provides you with a real-time preview. It shows you exactly how your thread is split, where the attached images are and the character limit.

But there is more! The preview also shows you information about tagged users. Hover over their name and you can see their info. This is great to make sure you are tagging the right person.

It also shows you the contents of quoted tweets. Every time you paste a link into the editor, ThreadStart makes sure to show you the quoted tweet.

But what about links to your website? As you know, Twitter shows little boxes of the websites you are linking to below your tweets. And so does ThreadStart!

The interactive real-time preview shows how tweets will be displayed.


Once you finish your thread you want to post it. In a perfect world, you would schedule it for the best time possible. When your audience is most active, and the chances of success are highest.

Lucky you, because that is very much possible. ThreadStart can tell you exactly when your audience prefers to engage with you and recommend you the right time to schedule.

But what about folks in different times zones? Time is relative and all that. Yup, they deserve to see your content just as much! Here is where the audience boost comes into play. By boosting you will retweet your content automatically at a later time. This puts your content back at the top of your followers' feeds. Awesome!

Quickly schedule your postings for the perfect time.

"What about when I go viral?" you ask. I've got two more cherries for the top of your thread sundae: plug & retweet-first tweets.

Plug tweets

It does not matter if you have a Soundcloud or an ebook. Once you go viral, it is a good time to tell the people about your work. There might be someone interested after all. The perfect time to plug your product!

Instead of looking at the like counter of your thread, waiting patiently for the perfect opportunity to post your plug, let ThreadStart do exactly that. You tell ThreadStart what to plug and it will take care of posting it at the right time.

Have a plug tweet ready for when your posting becomes viral.

RTF tweets

RTF stands for retweet-first. These tweets link back to the first tweet of your thread. You put them at the end of a long thread, so that the reader can quickly jump back to the top. Like how a lot of websites have a "back to the top" button.

These tweets are a good place to ask your supporters to give your first tweet a little push by retweeting it. Think of it as the call-to-action of your thread.

Add a retweet-first tweet at the end of your thread.


Lists are one of the standard elements of writing. They help readers scan the content. They are great to give your posting structure. And they should not be hard to add to a thread.

Twitter itself does not support lists. But you can easily work around this limitation by creating lists through emojis. And while that works, it is also cumbersome.

The new editor lets you create lists quickly and easily. Exactly like you already know it from your standard text editor. And with the click of a button, you can change the style of your lists.

Quickly add a list to your thread.

Thread Options

Writing threads often requires a few extra tools that ThreadStart brings to the table.


The first of them is the thread marker. It helps you highlight your tweet is in fact a thread. While this might not seem like a big deal, it is. If a reader scanning the feed does not realize your tweet is the beginning of a thread, they will not click on it. They might like it, but then they will keep scrolling. Without ever reading what was below the initial tweet.

With ThreadStart's marker tool you can add a short indicator that your posting is a thread.

Indicate the beginning of a thread with a thread marker.


Another best practice, especially for longer threads, is numbering the tweets. Imagine a thread containing 50 postings. A reader does not know how long your thread is before reading it. They might drop off right before the end, just because they thought it would never end.

By numbering your tweets, you set the expectation of how much they can expect. How much time they need to invest in reading. And how close they are to the end. There are different formats for numbering a thread. Showing how much is left, showing the "page" you are on, etc. They have one thing in common, though, it is a huge amount of work to number them by hand.

ThreadStart can number them for you with the click of a button. Easy & fast!

Easily number the tweets of your thread.

Text Splitting

Arguably the most important thread helper. Splitting the text into tweets is the heart of the editor. This is what it is all about. Twitter's native thread experience is seriously lacking in comfort. You cannot move quickly from one tweet to the next. It is cumbersome to create new tweets. And copying text from one to the other is annoying.

In ThreadStart splitting the text is a natural part of writing. You can split it automatically or use the hotkeys to start a new tweet. And you will still always know exactly where the borders of each tweet are. They are marked with horizontal lines inside the editor.

Text splitting helps you create a thread out of your long texts.

There's even more to come soon...

The editor v2 is already a 10x improvement on the previous one. But, I still have some ideas left, to take it to the very next level. I have already hinted at them on Twitter. So, if you want to make sure you are not missing the latest updates, make sure to follow me. I am sharing sneak peeks at what is currently under development and I often look for beta testers.

Now there is only one more thing to do for you...
