Ninecast turns the content calendar you already keep in Notion or Airtable into a live Instagram grid preview, then publishes each post to your social accounts on its date. Multi-platform scheduling from one plan, Canva designs as artwork, and captions published exactly as written. Instagram reach, likes, comments, saves and views are written back into the row that planned the post. Nothing to migrate: it reads your own fields. The grid preview is free forever.
