What is Yapzy?
Yapzy is a free Chrome extension that generates AI-powered replies and comments inside Twitter/X, LinkedIn, Facebook, YouTube, Instagram, Threads, Reddit and TikTok. Instead of switching tabs to ChatGPT, you pick a tone (agree, funny, hot take, supportive, clever, question, and more), click once, and Yapzy fills your reply box with a human-sounding response in under 5 seconds.
It supports 200+ AI models from 12+ providers — OpenAI (GPT-4o), Anthropic (Claude), Google Gemini, Groq, DeepSeek, Mistral, xAI (Grok), Perplexity and more — and you bring your own API key. The extension has no Yapzy backend and no database: requests go straight from your browser to your chosen AI provider. It works in 60+ languages, adapts its writing style to each platform's culture (casual on Twitter/X and Threads, professional on LinkedIn, community-aware on Reddit, punchy on TikTok), and actively avoids generic AI phrases so your replies sound like you wrote them yourself.
Writing social media replies takes forever
You see a post worth replying to. You start typing. Then you delete it. Retype. Delete again. Five minutes gone for one comment. Creators, marketers and founders lose hours every week on replies that could be generated in seconds.
Without Yapzy
- Stare at a blank reply box for 2 minutes
- Type, delete, retype, second-guess yourself
- Copy post → ChatGPT tab → prompt → wait → copy → paste back
- Reply sounds robotic or generic
- Give up and scroll past instead
With Yapzy
- Click one button — reply generated in under 5 seconds
- Pick your tone: agree, funny, hot take, clever
- Never leave the platform or switch tabs
- Replies match your voice and the platform's culture
- Actually engage instead of scrolling past
Features
An AI comment generator built for social media
Everything you need to reply on Twitter/X, LinkedIn, YouTube, Facebook, Instagram, Threads, Reddit and TikTok without ever leaving the platform.
Platform-aware voice
Casual on Twitter/X and Threads. Professional on LinkedIn. Engaged on YouTube. Familiar on Facebook. Emoji-friendly on Instagram. Community-aware on Reddit. Punchy on TikTok. Yapzy tunes tone, length and formality to how each platform actually talks.
8+ tones per reply
Agree, disagree, supportive, funny, clever, hot take, question, useful info. Pick the angle you want and Yapzy writes the reply that fits.
Sounds like you, not AI
Paste your bio in settings and replies match your personal voice. Yapzy blocks generic AI phrases (“absolutely,” “fascinating,” “indeed”) by default so nothing feels auto-generated.
200+ AI models, your key
Bring your own API key from OpenAI, Anthropic (Claude), Google Gemini, Groq, DeepSeek, Mistral, xAI Grok, Perplexity and more. Pick the model that fits your budget and taste.
Local-first, no Yapzy backend
No Yapzy server, no Yapzy database, no extension telemetry. Your API key is stored locally in Chrome and API calls go straight from your browser to your AI provider. We literally cannot see your replies.
60+ languages
Reply in English, Spanish, French, German, Portuguese, Japanese, Arabic, Hindi and 50+ more. Detects the post's language automatically or uses the one you set.
Nothing auto-posts
Yapzy fills your reply box — you stay in control. Edit, rewrite or toss the draft before you hit post. No autopilot, no bot behavior, no ToS risk.
Free forever tier
50 AI replies free, then 2 free replies every day — forever. No credit card, no signup. Pro is a one-time $19 for unlimited replies — never a subscription.

Testimonials
Loved by creators, marketers & founders
“I used to spend 30 minutes replying to comments after every video. With Yapzy it takes 5 and my audience actually thinks I'm more engaged, not less. Wild.”

“Engagement farming on LinkedIn is the whole job. Yapzy lets me comment on 10x more posts without sounding like a copy-paste bot. I'm seeing 3x the profile views.”

Growth marketer at a B2B SaaS
“The 'hot take' tone on Twitter is unreal. It writes the kind of replies that actually get impressions. It's like having a part-time ghostwriter for $19 one time.”

Yapzy is a free Chrome extension that generates AI-powered replies and comments directly inside Twitter/X, LinkedIn, Facebook, YouTube, Instagram, Threads, Reddit and TikTok. You pick a tone, click once, and the reply appears in the platform's native reply box in under 5 seconds.
Yapzy works on 8 platforms: Twitter/X, LinkedIn, Facebook, YouTube, Instagram, Threads, Reddit and TikTok. It automatically detects the platform you're on and adjusts tone, length and writing style to match each platform's culture.
Yes. Yapzy fully supports Threads (threads.net and threads.com). The Yapzy button appears in any reply or post box on Threads — pick a tone, click, and a conversational reply that matches Threads' casual culture is generated in under 5 seconds.
Yes. Yapzy supports Reddit across new Reddit, old.reddit.com, sh.reddit.com and m.reddit.com. The Yapzy button appears in any comment box on a post or reply — pick a tone like 'useful info,' 'clever' or 'hot take,' and Yapzy writes a community-aware comment that doesn't sound like a bot.
Yes. Yapzy supports TikTok on both tiktok.com and m.tiktok.com. The Yapzy button appears in any comment box under a video — pick a tone like 'funny,' 'hot take' or 'supportive,' click, and Yapzy writes a short, punchy comment that fits TikTok's fast-scrolling culture in under 5 seconds.
With ChatGPT, replying to a post means: copy the post, switch tabs, write a prompt, wait, copy the reply, switch back, paste it. Yapzy does all of that in one click, inside the platform, with the post context already loaded. It also knows each platform's culture — casual on Twitter, professional on LinkedIn — and actively blocks generic AI phrases so replies sound human.
Yes. Yapzy is free to install and you get 50 AI-generated replies upfront — then 2 free replies every day, forever. No credit card, no signup. If you reply more than that, Yapzy Pro is a one-time $19 payment for unlimited replies — never a subscription.
Yapzy itself is free for your first 50 replies, plus 2 free replies every day thereafter — forever. If that's not enough, Pro is $19 one-time for unlimited. You also pay your AI provider directly for API usage, which typically costs a fraction of a cent per reply. A full month of heavy use on GPT-4o mini or Groq usually costs under a dollar in API credits.
Natural. Yapzy blocks generic AI phrases like 'absolutely,' 'fascinating' and 'indeed' by default. Paste your bio into settings and replies match your personal voice — the people you reply to won't know it wasn't typed by hand.
200+ models from 12+ providers: OpenAI (GPT-4o, GPT-4o mini), Anthropic (Claude 3.5 Sonnet and Haiku), Google Gemini, Groq, DeepSeek, Mistral, Together AI, OpenRouter, xAI Grok, Fireworks, Perplexity and DeepInfra. You bring your own API key and pick the model you want.
The Yapzy extension is safe and local-first: there is no Yapzy server, no Yapzy database, no extension telemetry, and no logs of your replies. Your API key is stored locally in Chrome and API calls go straight from your browser to your chosen AI provider. (Like most software-product sites, getyapzy.com itself uses standard analytics — fully disclosed on /privacy.)
Yapzy is designed to keep you in control: it generates a draft that you review and post yourself — nothing is auto-posted, and no engagement is automated. AI-assisted drafting is generally accepted across the supported platforms (Twitter/X, LinkedIn, YouTube, Facebook, Instagram, Threads, Reddit and TikTok), but each platform sets its own content and automation policies, so what you ultimately post is your responsibility. We don't speak for any platform — check their current terms if you're unsure.
Yes. Yapzy generates replies in 60+ languages. It auto-detects the language of the post you're replying to, or you can lock in a preferred language in settings.
Any Chromium-based browser: Google Chrome, Brave, Microsoft Edge and Arc. Install it from the Chrome Web Store and it works in all of them.
Yes. If Yapzy Pro doesn't save you time, email support@yapzy.com and we'll refund you. No questions, no forms, no hoops.
