One post. Six platforms. Done.

ContentSplit is a platform-agnostic content repurposing tool designed to transform long-form content into optimized versions for multiple digital platforms. It accepts input such as blog posts, newsletters, interview transcripts, or any text-based content and generates tailored outputs for Twitter, LinkedIn, Instagram, TikTok, email, and Facebook. The tool is intended for content creators, marketers, and communications professionals who manage cross-platform publishing but lack the time or resources to manually adapt a single piece of content for each channel’s distinct format, length, and audience expectations.
Unlike generic paraphrasing tools, ContentSplit incorporates platform-specific structural conventions—such as Twitter thread formatting, LinkedIn professional tone norms, Instagram carousel framing, TikTok script pacing, email teaser hooks, and Facebook discussion prompts—while preserving core messaging and factual integrity. It operates entirely in-browser with no account requirement for initial use.
Users begin by pasting their source content into a text field. They then select a preferred tone of voice from the available options, which guides stylistic choices across all outputs. Upon submission, the system applies rule-based and AI-assisted transformations calibrated to each target platform’s best practices. For example, Twitter output follows thread logic with numbered points and line breaks; LinkedIn output emphasizes insight-driven phrasing and professional framing; Instagram output suggests visual-first language suitable for carousels; TikTok output adopts concise, spoken-word cadence; email output includes subject line and preview text; and Facebook output encourages open-ended questions or community-focused prompts.
The transformation does not involve external API calls or persistent storage—the processing occurs client-side or via secure server-side inference without retaining user content. Outputs are presented simultaneously in a side-by-side or scrollable layout, allowing users to review, copy, or further edit individual versions before publishing.
ContentSplit supports efficient content operations by eliminating redundant manual rewriting. Marketing teams use it to scale campaign assets from a single whitepaper or case study. Solopreneurs and freelance writers apply it to maintain consistent brand voice while meeting platform-specific engagement requirements. Educational creators repurpose lecture transcripts into digestible social formats. Internal communications teams adapt company announcements for both formal (email, LinkedIn) and informal (Facebook, Instagram) employee channels. Because outputs preserve key claims, data points, and narrative flow across variants, the tool supports message discipline without sacrificing platform appropriateness.
