# What HeyMark does, one job at a time.

Replying to comments and DMs with AI, comment-to-DM automation, moderation, scheduling, agencies, and running your social media from Claude or ChatGPT. Each page answers one question.

## Features and use cases

- [AI agent for social media: what it does on its own and what you decide](https://heymark.ai/en/solutions/ai-agent-for-social-media/): What an AI agent for social media does and how it differs from an assistant: it plans, writes in your voice, publishes, replies and reports, with your approval.
- [Instagram DM automation: auto DM everyone who comments your keyword](https://heymark.ai/en/solutions/instagram-dm-automation/): Instagram DM automation for comments: anyone who comments your keyword gets a public reply and a DM with your link. On every HeyMark plan, no credits spent.
- [Instagram comment auto reply, written by AI in your brand's voice](https://heymark.ai/en/solutions/ai-comment-replies/): Set up Instagram comment auto replies with AI that writes in your brand's voice, with approval and handoff to a person. When to use keywords, AI or neither.
- [Social media comment moderation with AI, and nothing deleted without you](https://heymark.ai/en/solutions/comment-moderation/): Social media comment moderation with AI: spam, insults and outside links get hidden or held for review, and deleting a comment always needs your approval.
- [Unified social media inbox: every comment and DM, answered in your voice](https://heymark.ai/en/solutions/unified-social-inbox/): A unified social media inbox for the comments and DMs on your accounts, with AI replies in your voice, handoff to people and access from Claude or ChatGPT.
- [Social media management tool for agencies, with client approvals](https://heymark.ai/en/solutions/agencies/): A social media management tool for agencies: one brand per client, client approval links on every plan, an AI inbox in each brand's voice and MCP for Claude.
- [Schedule social media posts with every network's options](https://heymark.ai/en/solutions/schedule-social-media-posts/): Schedule social media posts on Instagram, TikTok, LinkedIn, Facebook and YouTube with each network's options, from where you plan them or from Claude.
- [Social media MCP vs API: which one you need](https://heymark.ai/en/solutions/social-media-mcp-vs-api/): Social media MCP vs API: software that posts for many users needs an API. If your AI assistant posts and replies for your brands, an MCP server is enough.
