Sydium

Sydium learns a user's unique writing style, including cadence, vocabulary, and point of view, from existing content like posts, websites, or brand documents. This learned voice is then applied to all generated content and replies to ensure authenticity.

Content can be published to eleven social media platforms (Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, Bluesky, Threads, Mastodon, Google Business). The platform provides platform-specific previews and adapts content wording for each, allowing users to review changes.

Sydium includes built-in studios for creating visual content: Image Studio (AI image generation and editing), Video Studio (trimming, captioning, audio layering), and Carousel Studio (writes slides, designs them, and formats for each platform). These are integrated directly into the post composer.

The tool provides three daily content ideas derived from what people search around the user's niche, rather than trending topics. Each idea comes with a brief (angle, hook, what to show) and can be imported into the composer with one click.

Comments from eight platforms and DMs from Instagram and Facebook are consolidated into a single inbox. Sydium drafts replies in the user's brand voice, based on the recent conversation, which can be sent directly or edited first.

Users can schedule posts to the minute, drop them into recurring slots, or set them to repeat. An optional Autopilot mode drafts the coming week's content per brand, allowing users to review, approve in batches, or let it publish autonomously.

Sydium provides metrics reported by each connected platform, viewable per post and over time. Users can identify top-performing posts, sort them, and repurpose the best content. Shareable reports with expiry and password protection are also available.

For agencies, Sydium offers client workspaces, each with its own brand voice, dedicated portal, and approval workflows. This includes scheduled client reports and increased team seats and autopilot accounts.
