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) ## ReplyGPT ReplyGPT is a lightweight Chrome extension created for people who want to stay visible on social platforms but find writing comments tedious. Once installed and connected to a ReplyGPT subscription, it places AI drafting tools directly inside the interfaces you already use — Facebook, LinkedIn, X/Twitter and Quora — so a reply can be generated without leaving the page. The workflow is prompt-based: you describe the style or message you want, and the extension produces a reply that you can edit before posting. The product is aimed at social media managers, sales and marketing professionals, community builders and creators who comment at volume. Rather than replacing human judgement, it speeds up the first draft so users can focus on the parts that actually need a personal touch. The extension is published by an independent developer and distributed through the Chrome Web Store. The Chrome Web Store listing shows a small but non-zero install base and a version history reaching 2024. The publisher requires a paid ReplyGPT subscription for use, so the free element is limited to installing the extension. Specific plan pricing is published on the ReplyGPT website rather than in the store listing. **Pricing & Plans:** Freemium-style access: the Chrome extension itself is free to install, but an active subscription on replygpt.com is required to generate replies. Current plan tiers and prices are shown on the ReplyGPT website. - **AI comment generation on four platforms:** Generate context-aware comment suggestions directly on Facebook posts, LinkedIn feeds, X/Twitter threads and Quora answers. - **Prompt-driven replies:** Type a short prompt describing the tone or angle you want, and ReplyGPT turns it into a ready-to-post reply. - **In-page drafting, no tab switching:** Drafts appear inline where you are already reading, so you never have to switch tabs or copy text between tools. - **Editable before you publish:** Suggestions are inserted as editable drafts, letting you adjust wording and voice before publishing. - **Chrome-native and privacy-conscious:** A lightweight Chrome extension that follows the developer's recommended data practices and does not sell user data. **Strengths:** Speeds up comment writing across four major social platforms from one extension; Prompt-based tone control lets you match the voice of each platform; Suggestions appear inline, so no copy-pasting between apps; Editable drafts keep a human in the loop before posting **Limitations:** Requires a separate paid subscription on replygpt.com before the extension is usable; Small user base and a very limited number of reviews, so community feedback is thin; Works only inside supported sites (Facebook, LinkedIn, X/Twitter, Quora) via the Chrome browser; AI-written comments can feel generic if prompts are not specific [Profile (Markdown)](https://openaitools.app/tool/replygpt.md) ## Frequently Asked Questions ### How do Comment Generator and ReplyGPT compare in monthly traffic?
