Learns your writing voice from past posts, then drafts and schedules across ten social networks
Sydium is a social publishing tool whose pitch is voice: it trains on your existing posts and site content and drafts in that register rather than in generic marketing prose. It covers Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, Bluesky, Threads and Mastodon, with autopilot accounts, approval steps and client portals on the agency tier. Plans are counted in posts rather than credits: about twenty-eight dollars a month on annual billing for three hundred posts and five autopilot accounts, seventy-nine for eight hundred posts, twenty accounts and ten seats, and four hundred and ninety-nine at the top. There is no free tier and the fourteen-day trial takes a card up front. It is built and run by a single founder in Brasov, Romania.
Pro $28/month billed yearly ($35 month-to-month) for 300 AI-generated posts and 5 autopilot accounts; Agency $79 yearly ($99 monthly) for 800 posts, 20 accounts, 10 seats and 20 client portals; Enterprise $499 yearly with custom terms. No free tier; the 14-day trial requires a card but charges nothing until day 14.
Use tool ↗Counting plans in posts instead of opaque credits is refreshing, and the voice training plus the ten-network spread including Bluesky, Threads and Mastodon covers more ground than most schedulers. The thing to weigh is concentration risk: this is one person's product, and the top tier sells a priority line to that person.
Watch out: Headline prices assume annual billing; month-to-month is $35 and $99, and the trial charges automatically on day 15 unless cancelled.
