FAQ
How does the tweet thread planner work?
Paste your long content (blog post, article, or rough thoughts), pick a tone, and the tool splits it into tweet-sized chunks (≤280 chars each, respecting sentence boundaries). It generates a hook tweet from the most engaging sentence, a CTA tweet asking for engagement (retweet/reply/follow), inserts transition words (But, And, So, Here's why, Plus) between tweets, and applies 1/, 2/, 3/ numbering.
Which tones are supported?
Five tones: informational (factual, clear), controversial (contrarian, debate-sparking), storytelling (narrative arc, hooks), listicle (numbered items, scannable), and thread-bois (casual, meme-aware, 'hot take' style). Each tone rewrites transitions and the hook to match its voice.
What is the engagement score estimator?
A heuristic score (0-100) based on hook strength (question/number/controversy), thread length (4-10 tweets optimal), presence of a CTA, average char count per tweet, and transition quality. Useful as a relative gauge when iterating — not a guarantee of virality.
