Saves time on LinkedIn replies.
Needs your own API key, but works fine.
Handy tool.
A bit clunky UI sometimes.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Generate suggestions for LinkedIn, Instagram and Twitter/X from a single extension, each with its own tuned default prompt.
Choose how many comments to produce and how many words each one should have, then move between options with arrow controls.
Generate in the language of your audience and save, edit or delete your own reusable prompt templates.
Click the refresh control next to the post, accept a draft with the check icon, tweak the wording and publish directly in the feed.
Comment-AI is built around a simple observation: most people want to reply to interesting posts but stall when it comes to phrasing. The extension sits inside Chrome and injects a small control menu next to the text you select, so the act of commenting happens in the same tab where you are already reading.
Its workflow is deliberately staged. You pick LinkedIn, Instagram or Twitter/X, name a prompt, decide how many comments to generate and how long each should be, and choose an output language. From then on, selecting any post text and clicking the generate control produces a set of drafts you can page through with back and forward arrows, accept with a checkmark and refine before posting.
Comment-AI is an independent extension offered by the Comment-AI publisher and is not affiliated with LinkedIn, Meta or X. It uses your own OpenAI API key, which means the extension itself has no separate token budget — you bring the key and pay OpenAI for usage. The listing shows a stable feature set and a 4.6 rating from a modest number of reviewers.
Reply to posts in your feed faster while keeping control over tone, length and language with reusable prompt templates.
Draft casual, on-brand replies to Instagram posts so you can stay present in comments without burning time on phrasing.
Generate comment options in your audience's own language and pick the one that reads most naturally.
