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) ## OpenRepli OpenRepli is a small Chrome extension aimed at one repetitive job: writing comments and replies on social networks. Instead of switching tabs to a chatbot, you click the OpenRepli icon in the reply box on LinkedIn, Twitter/X or Instagram and it produces a ready-to-edit comment based on the conversation in front of you. The design philosophy is bare-bones and privacy-first. There is no signup and no account: you paste your own OpenAI API key into the extension and it calls the API directly from your browser. The developer's Chrome Web Store disclosure states that data is not sold to third parties and is not used for creditworthiness or unrelated purposes, which is a meaningful contrast to tools that route your social activity through their own servers. OpenRepli is a niche, early-stage utility rather than a full social media suite. The store listing shows version 0.1.1 (updated April 2024), a footprint of roughly 24 KB, and a very small user base with no ratings yet. That makes it attractive for individuals who want a lightweight reply helper at no extra cost beyond their own API usage, but a poor fit for teams needing scheduling, analytics or multi-seat management. Note that this is an independent third-party extension and is not an official OpenAI product, even though it relies on the OpenAI API. **Pricing & Plans:** Free. OpenRepli is a free Chrome Web Store extension with no subscription; you supply your own OpenAI API key and pay OpenAI directly for the API usage you generate. - **One-click reply generation:** Open the extension icon in the comment interface on LinkedIn, Twitter/X or Instagram and it drafts a reply for that specific thread. - **Bring your own OpenAI key:** Paste your own GPT API key in the extension settings — no account, no proxy server, and no data collection per the developer's disclosure. - **Customizable instructions:** Write instructions to match your brand voice or personal persona so generated comments sound like you rather than a default chatbot. - **In-browser, cross-platform:** Runs as a lightweight Chrome extension (about 24 KB) directly in the sites you already use, so there is nothing heavy to install or manage. **Strengths:** Completely free extension with no subscription tier; No signup or account required; Works inside LinkedIn, Twitter/X and Instagram without leaving the page; Custom instructions adapt replies to your brand or persona **Limitations:** Very small install base (about 7 users as shown on the store listing) and only version 0.1.1; No ratings yet, so quality signals from other users are essentially absent; Requires your own OpenAI API key and the associated usage costs; Limited to LinkedIn, Twitter/X and Instagram, with no scheduling, analytics or team features [Profile (Markdown)](https://openaitools.app/tool/openrepli.md) ## Frequently Asked Questions ### How do Comment-AI and OpenRepli compare in monthly traffic?
