Koast AI is an AI-powered tool designed to help users generate and schedule thoughtful LinkedIn comments to boost their visibility, engagement, and personal brand. Unlike tools focused on content creation, Koast AI operates in the comments section—helping users appear consistently across their network by offering authentic, value-adding responses to LinkedIn posts.
By allowing users to schedule AI-generated comments on posts from thought leaders, colleagues, or niche-specific creators, Koast AI automates a key but often overlooked aspect of social growth—replying. Whether you’re a founder, solopreneur, or content creator, Koast AI helps you stay visible without being online 24/7.
Features
1. AI Comment Generation
Koast AI creates context-aware, thoughtful comments tailored to LinkedIn posts, ensuring your replies feel authentic and relevant.
2. LinkedIn Post Integration
Paste a LinkedIn post URL into Koast, and the AI will generate a series of responses you can use or edit.
3. Scheduled Commenting
Choose when your comment goes live, letting you “engage while you sleep” or plan weeks of LinkedIn interaction in advance.
4. Tone and Intent Customization
Customize the tone (professional, casual, curious, etc.) or define a goal (add value, ask a question, express support).
5. Comment Library
Save and reuse previously generated or posted comments, allowing for brand consistency and faster scheduling.
6. Multi-Comment Queuing
Queue up comments on multiple LinkedIn posts to maintain daily engagement across your niche.

Comparison with Other Tools
vs. Taplio
Taplio offers a broader range of LinkedIn features (scheduling, CRM, analytics). Koast AI focuses solely on engagement via comments, making it simpler and more streamlined.
vs. TalkBackAI / ReplyDude
Those tools generate replies but do not offer scheduling or commenting at scale. Koast stands out with its planning and automation features.
vs. ChatGPT
While ChatGPT can write replies, it lacks the scheduling and platform-specific customization that Koast provides for LinkedIn growth.
Customer Reviews and Testimonials
Although Koast AI is relatively new, early users have shared enthusiastic feedback online:
“Game-changer for my daily LinkedIn presence.”
“I schedule my engagement for the whole week in under 10 minutes.”
“Finally, a tool that focuses on the part of LinkedIn that actually drives relationships—comments.”
As Koast grows, expect to see more user reviews on Product Hunt, G2, and in LinkedIn creator circles.
Conclusion
Koast AI is a focused, smart solution for professionals who want to grow their presence on LinkedIn through consistent, authentic engagement. By helping users generate and schedule meaningful comments, it fills a unique gap in the social media tool landscape—turning engagement into a strategy, not just an afterthought.
