How do I split tweets in the thread?

Add a line with just --- (three dashes) between each tweet. The formatter splits your content at those separators and shows each tweet separate card.

What is the Twitter character limit?

Each tweet is limited to 280 characters. The formatter counts characters per tweet (including the numbering suffix like '1/5') and highlights in red if a tweet exceeds the limit.

Does the numbering (1/5, 2/5…) count toward the limit?

Yes. The numbering suffix is appended to each tweet when calculating the character count. Keep this in mind when writing tweets that are close to 280 characters.

How do I copy the tweets to post?

Use 'Copy tweet' to copy a single tweet, or 'Copy all tweets' to get all of them separated by a divider. Then paste each one manually into Twitter/X.

Here's everything I know about building a great product in 2025:

---

Start with the problem, not the solution.

Most founders fall in love with their idea. Smart founders fall in love with the problem.

Ask: "Would people pay to make this pain go away?" If yes, keep going.

---

Talk to 10 customers before writing a single line of code.

You'll learn more in 5 conversations than 5 months of building.

The goal: find the pattern in their frustration.

---

Build the smallest possible thing that solves the core problem.

Not an MVP. A *single valuable thing*.

Cut features ruthlessly. If it's not essential, it's a distraction.

---

Charge from day one.

Free users give you vanity metrics. Paying users give you signal.

If nobody pays, the problem isn't painful enough.

---

Iterate weekly, not monthly.

Speed is your only advantage over larger competitors.

Ship. Measure. Learn. Repeat.

Write, format, and preview Twitter/X threads before posting

Twitter/X threads consistently generate more engagement, saves, and follower growth than standalone tweets because they let you develop ideas in depth. But writing a good thread is hard when you're counting characters manually and toggling between a notes app and Twitter's composer. This thread formatter lets you write your full thread in one place, automatically splits it at 280 characters, numbers each tweet, and gives you a tweet-by-tweet preview before you post.

What makes a thread go viral?

High-performing threads follow a predictable structure. The first tweet must hook the reader in the first 10 words — it is the only tweet shown in the timeline until someone taps "Show thread". Use a bold claim, a surprising statistic, or a direct promise. Tweets 2–5 deliver on the hook with specific, actionable content. The middle tweets (6–10) go deeper. The final tweet is a strong takeaway or call to action, since some readers jump straight to the last tweet. Always end with a question or a request to retweet to drive engagement signals.

Thread length — how many tweets is optimal?

Data from high-follower accounts suggests that 7–15 tweets is the sweet spot for most topics. Shorter threads feel incomplete. Longer threads (20+) lose readers around tweet 8 unless the content is genuinely exceptional or highly technical. Educational threads about finance, coding, history, and career advice tend to perform well at 10–15 tweets. Opinion threads and personal stories work best at 5–8 tweets with a punchy, memorable closing line.

Twitter/X character limit — what counts?

Each tweet has a 280-character limit. URLs always count as 23 characters regardless of their actual length (Twitter uses t.co shortening). Images, GIFs, and polls don't consume character space. Emojis count as 2 characters each in most cases. Line breaks count as 1 character. This formatter counts characters accurately using Twitter's rules, so you won't be caught off-guard when pasting into the composer.

Numbering conventions for threads

The most common convention is to add a tweet counter (1/, 2/, 3/ etc.) either at the start or end of each tweet. Starting with the counter (e.g. "1/ The biggest mistake founders make…") signals to readers immediately that this is a thread. Ending with the counter keeps the hook clean. This formatter supports both styles and adds numbering automatically so you can focus on writing, not formatting.
