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. **Pricing & Plans:** Free to install. Comment-AI does not charge its own subscription; you supply your own OpenAI API key and pay OpenAI for the tokens consumed, which requires billing enabled on your OpenAI account. - **Multi-platform comment generation:** Generate suggestions for LinkedIn, Instagram and Twitter/X from a single extension, each with its own tuned default prompt. - **Comment count and word count control:** Choose how many comments to produce and how many words each one should have, then move between options with arrow controls. - **Multilingual output and custom prompts:** Generate in the language of your audience and save, edit or delete your own reusable prompt templates. - **On-page menu workflow:** Click the refresh control next to the post, accept a draft with the check icon, tweak the wording and publish directly in the feed. **Strengths:** Works across LinkedIn, Instagram and Twitter/X in one extension; You control comment count, word count and output language; Reusable custom prompts that can be added, edited or deleted; Each platform ships with a sensible default prompt **Limitations:** Requires your own OpenAI API key with billing enabled, so costs sit outside the extension itself; Only supports GPT-3.5 Turbo at present, not newer models; Comment generation can be blocked if you don't confirm or cancel a previous comment first; Version has not been updated since November 2023 [Profile (Markdown)](https://openaitools.app/tool/comment-ai.md) ## RplyAI RplyAI is a browser extension built around one narrow, practical job: helping you show up in social conversations without staring at a blank comment box. When you open a post, an AI Assist control appears next to the comment area. The extension reads the post's content and proposes a relevant, professionally worded response, which is placed into the comment field for review. The pitch is personal branding rather than brute-force automation. The extension is aimed at people who want to stay visible and engaged in professional networks but who find writing a meaningful comment on every relevant post time-consuming. Because the draft lands in the normal comment box, you stay in control of the final wording before anything is published. The listing covers LinkedIn as the supported platform and advertises a 14-day free trial, with support handled through the developer's own site. It is a small, single-purpose companion tool rather than a full social media management suite. **Pricing & Plans:** Free trial (the Chrome Web Store listing advertises a 14-day free trial); continued use requires a paid plan arranged through the developer. Verify current pricing on the developer's site. - **AI comment generation:** Produces a context-aware comment based on the post you are viewing, so replies stay on topic instead of generic. - **One-click insert:** An AI Assist button sits inside the comment section and places the generated draft directly in the comment box. - **Draft-then-edit flow:** Nothing is posted automatically — you review and adjust the suggested wording before it goes out. - **LinkedIn-oriented:** Optimised for professional network conversations where tone and wording matter. - **Privacy-conscious handling:** The developer states user data is not sold to third parties or used outside the extension's core functionality. **Strengths:** Removes the blank-page problem when you want to comment but have nothing ready to say; Keeps a human in the loop by inserting drafts rather than auto-posting; Simple, single-purpose interface with no steep learning curve; Free trial lets you test the output quality before paying **Limitations:** Narrow platform coverage compared with broader social engagement suites; Very small user base and no ratings, so long-term maintenance is unproven; Generated comments still need editing to avoid sounding formulaic [Profile (Markdown)](https://openaitools.app/tool/rplyai.md) ## Frequently Asked Questions ### How do Comment-AI and RplyAI compare in monthly traffic?
