PostAi: AI Posts & Auto Reply

PostAi is the AI post generator for Instagram: create the image, caption and hashtags in seconds, then turn comments into customers with auto reply and comment to DM automation.

Built for content creators, small businesses and entrepreneurs who want to post consistently and answer every comment, without a designer and without spending hours.

▸ AI post generator
• 20+ templates: product launch, sale, "comment to get it", reel cover, carousel, tips, quotes, behind the scenes, giveaway, testimonial, before and after, myth vs. fact, top lists, lead magnet, events, local business, food, seasonal and more
• Free-form post: describe your idea and AI creates the whole post
• AI posts ready to publish: image, caption and hashtags together
• 1:1, 4:5 and 9:16 formats for feed, stories and reel covers
• AI captions and hashtags in 6 languages: English, Spanish, Portuguese, French, German and Italian

▸ Auto reply and comment to DM (beta)
Someone comments "LINK" on your reel? PostAi replies publicly and sends them the link by auto DM, day and night. That's comment to DM.
• Keyword rules (LINK, PRICE, INFO) or auto reply to any comment
• On all your posts or on one specific post or reel
• Public reply, private DM or both
• 1 to 5 rotating versions so your auto replies don't sound like a bot
• AI writes your public replies and auto DM messages
• Rule templates: Link by DM, Price, Giveaway, Free resource and Thank every comment
• Test a rule before turning it on, and check every reply and DM in the activity log
• Alerts when an account needs to reconnect, so your Instagram automation never stops
Instagram automation is in beta: we're opening Instagram connections in phases. Launch offer: automate 1 account for free for a limited time.

Tip: create a "comment to get it" post with the AI post generator and turn on a comment to DM rule with the Link by DM template. Your followers comment, PostAi delivers the link by auto DM.
