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.

Each tweet is limited to 280 characters. Red border = over limit, trim that tweet. Numbers like "1/5" count toward the character limit.

Write and format Twitter/X threads

Threads are one of the highest-engagement formats on Twitter/X. Use the separator (---) to break your long-form content into individual tweets, check none exceed 280 characters, and copy them to post in sequence.

Frequently asked questions

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 as a 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.
