FAQ
How does the social media post generator work?
Enter a topic, your key points (one per line), pick a tone (professional, casual, friendly, urgent, inspirational, or humorous) and a target audience, then select platforms. The tool composes a tailored post per platform — respecting each platform's character limit (Twitter 280, Mastodon 500, Instagram 2200, LinkedIn 3000, Facebook 63206), and appending platform-appropriate CTA, hashtags, and emojis.
Which platforms are supported?
Five platforms: Twitter/X (280 char max), LinkedIn (3000 char max, 1300 optimal), Facebook (477 chars optimal), Instagram (2200 chars max, 125 above fold), and Mastodon (500 chars max). Each platform gets its own CTA (e.g. 'Link in bio' for Instagram, 'Retweet' for Twitter), its own hashtag count (Instagram 10-30, LinkedIn 3-5, Twitter 2-3), and tone-aware emoji if enabled.
Can I generate multiple post variations?
Yes. The tool produces three variations per platform per generation, each with a different hook (question, statement, story-style). You can copy any variation or download the whole batch as a text or CSV report (platform, post_text, char_count, hashtag_count).

(12) History (localStorage, last 20). (13) Shareable URL (inputs encoded in hash). (14) Summary stats (total platforms, posts, total chars, avg chars). (15) Best-time-to-post suggestion per platform. (16) Live char count with platform color coding (green/yellow/red). (17) 3 variations per platform (different hooks).
Is my data sent anywhere?
No. All post generation runs locally in your browser. History is stored in localStorage on this device only.
