Instead of producing generic one-liners, the extension reads the caption of the post in front of you and drafts a reply grounded in that specific content, which is why the results sound more like a person and less like a template. Setup takes about a minute. You install the extension from the Chrome Web Store, sign up with an email address to activate a free trial, and then tell the tool how you write: your own instructions, preferred tone and the objective of a given comment, such as agreeing, disagreeing or adding insight. From then on, each draft appears alongside the post for you to accept, tweak or discard. One design choice worth noting is that the extension never needs your platform credentials. It works as a layer on top of the site, and it always leaves the final action to you. The site also notes that comments are drafted in the language of the original post, so it works for languages beyond English. Paid plans and a developer API sit alongside the free trial. **Pricing & Plans:** A 7-day free trial with no credit card is offered, after which paid plans apply. Pricing and API terms are listed on the site's pricing page. - **Caption-aware drafting:** The extension reads the specific post before writing, so drafts reflect that content instead of a generic template. - **Custom voice instructions:** Tell it how you write and it aims for your tone or your brand's tone rather than a neutral AI register. - **Objective and tone controls:** Choose what the comment should do, such as agree, disagree or add insight, and how it should sound. - **No account access required:** It works as a browser extension layered on the platform and never asks for your login credentials. - **Multi-language support:** Comments are drafted in the language of the post, so it fits multilingual feeds. **Strengths:** Grounds drafts in the actual post caption rather than generic phrases; Learns your voice through custom instructions instead of default AI tone; Never requires your social account login credentials; Supports Instagram, LinkedIn and Threads, with multi-language drafting **Limitations:** It drafts but does not post, so it still requires your time on every comment; Works only in supported browsers as an extension, not as a standalone app; Free usage is limited to the trial window [Profile (Markdown)](https://openaitools.app/tool/comment-generator.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 Generator and RplyAI compare in monthly traffic?
