Supported Platforms
Platform specifications, character limits, and image ratios.
Brandmanna generates content for 8 platforms. Each platform has its own character limits, image ratios, and content adaptations. The AI automatically adjusts your content to fit each platform's requirements when you generate drafts.

Platform Details
Professional networking content with up to 3,000 characters. The AI optimizes for LinkedIn's algorithm by including strong opening hooks, structured formatting with line breaks, and professional CTAs. Posts are formatted for readability in the LinkedIn feed, where the first two lines determine whether readers click "see more".
Image ratio is 1:1 (square). You can attach images from your media library or generate AI images.
Visual-first content capped at 2,200 characters. The AI generates caption-style text with hashtag clusters positioned at the end, engagement-focused CTAs, and a conversational tone suited to Instagram's audience. Captions are structured to complement the visual content rather than stand alone.
Recommended image ratio is 3:4 (portrait), which takes up more screen space in the Instagram feed.
Twitter/X
Short-form content limited to 280 characters. The AI condenses your message into punchy, high-impact posts that work within the strict character limit. Hashtags are used sparingly (1-2 maximum) to preserve character space. The AI prioritizes clarity and impact over detail.
Image ratio is 16:9 (landscape), which displays well in the Twitter/X timeline.
Community-oriented content with a 3,000 character limit. The AI adapts tone for Facebook's conversational style, incorporating engagement prompts (questions, polls, calls for comments) and shareable hooks. Posts are structured to encourage interaction and sharing within Facebook groups and pages.
Image ratio is 1:1 (square).
Blog
Long-form content with no character limit. The AI generates structured articles with H2/H3 headers, body paragraphs, bullet points, and SEO-friendly formatting. Blog posts include meta descriptions, structured introductions, and clear conclusions with CTAs.
Featured image ratio is 16:9 (landscape).
LinkedIn Carousel
Multi-slide content for LinkedIn, with each slide limited to 300 characters across up to 10 slides. The AI structures your content into a visual narrative flow — typically an attention-grabbing title slide, supporting points across middle slides, and a CTA on the final slide.
Slide ratio is 4:5 (portrait) at 1080x1350 pixels. You can export carousels as branded PDF files ready for upload to LinkedIn. Requires the Creator tier or higher.
Landing Page
Full landing page copy with no character limit. The AI generates headline, subheading, feature sections, benefit blocks, social proof placeholders, and CTA blocks structured for conversion. The output is formatted as copy sections that you can drop into your landing page builder.
Hero image ratio is 16:9 (landscape). Requires the Creator tier or higher.
Newsletter
Email newsletter content with no character limit. The AI generates a subject line, preview text, greeting, body sections with headers, and a sign-off with CTA. Content is structured for email readers who scan quickly — short paragraphs, bold key points, and clear action items.
Header image ratio is 16:9 (landscape). Requires the Creator tier or higher.
Platform Adaptation
When you generate content for multiple platforms from the same brief, the AI creates a unique draft for each platform. It does not simply truncate or copy the same text. Each draft is independently written and adapted for the platform's:
- Audience expectations — Professional tone for LinkedIn, casual for Instagram, concise for Twitter/X.
- Formatting conventions — Hashtag placement, line breaks, emoji usage, CTA style.
- Character constraints — Content is written to fit, not cut to fit.
You can also transform an existing draft from one platform to another using the Platform Adaptation feature in the draft editor. This rewrites the content for the target platform rather than reformatting it.
Choosing Platforms
When generating content on the Generate page, you select your target platforms before generating ideas. The AI then produces platform-specific ideas — each idea is tailored to the platform it targets. You can select multiple platforms from the same brief to generate a cross-platform content set.
For Content Plans, you choose platforms at the plan level. The AI distributes content across your selected platforms according to your cadence and timeline.
