Buffer

Buffer is a social media management platform designed to help individuals and businesses plan, schedule, and publish content across various social media channels. It aims to streamline social media presence and engagement.

Buffer is a strong match for SmartPost Scheduler. It explicitly offers multi-platform scheduling, a calendar view for planning, and tools for content creation including an AI assistant for text suggestions. It also supports managing multiple social media accounts and has various subscription tiers, including a free plan. While mobile app access is implied for a social media management tool, it's not explicitly stated in the provided content, leading to a slightly lower confidence score.
