Free tools
Free tools, no account needed.
Four free tools for founders who post on LinkedIn and X, each running in your browser with no AI and no account: a post formatter for bold, italic, bullets and line breaks with the see-more fold drawn live, a post preview that shows the fold and counts what matters, an X thread splitter that runs the product's own splitting code, and a calculator that counts the post-worthy moments in your week.
The tools
Three jobs, done in the browser.
Nothing you type is sent anywhere. The formatter and the preview share one text box, so a post moves between them without retyping.
- Free
LinkedIn post formatter
Bold, italic, monospace and underline for a word or a line, bullets and arrows, a character count against the 3,000 limit, and the see-more fold drawn live.
- Free
LinkedIn post preview
Paste a post and see where the fold falls, what the first line shows, the paragraphs, hashtags and mentions, at desktop and phone width.
- Free
Posts in your week
Five numbers about your week, and back comes how many post-worthy moments it holds and which day each one should land on. No AI.
- Free
X thread splitter
Paste a take and see the tweets it becomes, split by X's own 280-character limit, with the Premium cap as a switch. The product's own splitter, in the browser.
Sonar
The tools finish a post. Sonar starts it.
Sonar reads your calendar, meetings and Slack, keeps the moments worth saying, and drafts LinkedIn and X posts in your voice. You approve each one. How it works.
