Frequently Asked Questions

Everything you need to know about CommentOne safety, features, and plans.

CommentOne is built to be a low-risk writing assistant, not a bot. No tool can guarantee LinkedIn will never restrict an account, but using it the way we recommend keeps your risk low.

LinkedIn only flags accounts that use dangerous automated background bots—tools that scrape private APIs, auto-post hundreds of comments while you sleep, or spam identical copy-paste templates.

How CommentOne is fundamentally different:

  • 100% Human-in-the-Loop: CommentOne never auto-posts. It acts like an intelligent writing assistant right inside your comment box. You review the draft, edit it if you want, and click LinkedIn's native Post button with your own mouse.
  • Zero Internal API Scraping: We do not touch LinkedIn's private backend APIs or run headless bots. You are the one reading each post, reviewing the draft and deciding whether to post it.
  • Unique Contextual Thoughts: Every comment is original and tailored to the post's text and images. No repetitive spam patterns.
  • Zero Password Access: We never ask for or touch your LinkedIn password, cookies, or session tokens.

🛡️ Best Practice: For natural, sustainable profile growth, we recommend pacing your comments to 30–60 comments per day spread naturally across your browsing sessions.

Yes, you have full control over your subscription through your Lemon Squeezy portal. You can upgrade, downgrade, or cancel at any time with zero lock-in or cancellation fees.
When you comment on a post with an infographic, slide deck, or chart, CommentOne uses multimodal Vision AI to extract actual data points, percentages, and takeaways, weaving them seamlessly into your comment with exact metrics.
