Postkey automates Instagram DMs and comments and schedules posts, so a post and the DMs it brings in live in one place. A business, a creator or an agency can run it by hand, or let an AI assistant like ChatGPT, Claude or Cursor run it.
Rabbithole LLC makes it, and it's live at postkey.pro.
What we built
Comment to DM: someone comments a keyword and gets your link by DM. Keyword flows, follow to unlock and email capture work the same way.
An inbox for Instagram conversations, with AI replies to DMs and comments.
DM automation on Instagram, Messenger and X today. TikTok, WhatsApp and Telegram are next.
A post scheduler and calendar for 21 networks, from Instagram, TikTok and YouTube to LinkedIn, Google Business and Bluesky.
Many accounts on one plan: clients connect by invite link, and the team works from one inbox.
A remote MCP server, a REST API and webhooks, so ChatGPT, Claude, Cursor, Grok and other AI agents can set up automations, answer DMs and schedule posts.
Safe to hand to an AI agent
Replies can wait for your yes before they go out.
Every connection has its own limits.
A DM can never give your agent orders.
Built to be found
More than 60 guides, comparisons and blog posts as of November 9, 2026. Each comparison is built from the other tool's own pages, dated and with sources.
A page for each AI assistant it works with, and a file for answer engines (llms.txt) that describes the whole product.
How we use it ourselves
Before anyone else used it, we tested every DM path live on Rabbithole's own Instagram: DMs, comment replies and hiding a comment all passed on October 19, 2026.
Rabbithole's Instagram runs a comment-to-DM automation in Postkey.
Results
Postkey is new. We'll add its numbers here once there's a full month to report. No numbers until they're real.
