Length, formatting and free credits
Guests receive 5 credits per day. Sign in with your email for 20 daily credits and saved projects. Taglines use 5, 10 or 16 words per idea; headlines and subject lines have their own character limits. Longer drafts support up to 300 words for guests or 700 when signed in. Summaries stay shorter than the source. Optional explicit line limits apply only to replies and social captions. One generation or rewrite costs one credit; failed requests are refunded. Credits reset at midnight UTC.
Choose plain text, Markdown or WhatsApp formatting. Copy preserves the output’s line breaks and formatting markers. A line means an explicit line break, not wrapping on your phone.
Before you use the output
Review offers and availability before publishing. The tool drafts text; it does not publish to social accounts.
Your work stays yours to manage
Guest history stays in the current browser. Signed-in work is saved privately in the dashboard, where you can search all saved history, filter by tool, date and project, manage projects, continue editing, save versions or delete an item. Drafts are sent to our AI provider to generate the result. Do not submit passwords or sensitive personal data.
