Brand-specific moderation

BrandBastion moderation adapts to post context and can be customized with brand-specific models, sensitivity levels, and comment categories. You control what gets hidden by platform, campaign, or post type, while real-time alerts and AI summaries help your team spot emerging risks fast. It is not a one-size-fits-all model.

Advanced sentiment and AI insights

BrandBastion sentiment analysis uses your brand context and business goals to classify sentiment based on real impact. It captures industry nuance, sarcasm, and subtext, so a negative-sounding comment can still be recognized as positive when it signals real customer value.

Powered by Astra, our AI Analyst, teams can extract actionable insights from their social media interactions, from improving product feedback loops and managing crises to planning the next ad campaigns.

"Before BrandBastion, tracking conversations on social media and agent activity was a huge challenge. BrandBastion has been a game-changer for us. We've saved over 450 hours monthly in moderation and in responding efforts."

FAQs

 

How are BrandBastion replies different from AI reply suggestions?

BrandBastion prepares replies in advance and queues them in your inbox for review and batch approval. Replies are grounded in your website and help center content with sources visible, and they use full post context so they stay accurate, relevant, and on-brand at scale.

Can we keep humans in the loop and still move faster?

Yes. Human approval is the default. Agent+ drafts replies and holds them for review and batch approval. If you choose, you can automate only low-risk scenarios, like exact phrase matches or predefined intents, while keeping sensitive topics pending review.

What channels does BrandBastion cover that matter for modern social CX?

BrandBastion supports unified workflows across paid and organic comments, DMs, mentions, and reviews. This matters during spikes, influencer partnerships, and paid campaigns where coverage gaps create risk and manual load.

What insights and performance data does BrandBastion provide?

BrandBastion provides actionable insights across sentiment trends, conversation topics, reviews, paid and organic engagement, community growth, and operational performance. Teams can track everything from TikTok trends and post-level risk signals to moderation actions, reply performance, and CX agent productivity, all in one platform built to turn insights into action.
