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.

Which social media platforms does Yapzy support?

Yapzy works on 8 platforms: Twitter/X, LinkedIn, Facebook, YouTube, Instagram, Threads, Reddit and TikTok. It automatically detects the platform and adjusts tone, length and writing style to match each platform's culture.

Does Yapzy work on Threads?

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.

Does Yapzy work on Reddit?

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.

Does Yapzy work on TikTok?

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.

How is Yapzy different from ChatGPT for social media replies?

ChatGPT requires you to copy the post, switch tabs, write a prompt, wait, copy the output and paste it back. 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 gives you 50 AI-generated replies to start. After that, Yapzy Pro is a one-time $19 payment for unlimited replies — no subscription.

Do Yapzy's AI replies sound natural or robotic?

Natural. Yapzy blocks generic AI phrases like 'absolutely,' 'fascinating' and 'indeed' by default. You can paste your bio into settings to make replies match your personal voice.

Which AI models does Yapzy support?

Yapzy supports 200+ models from 12+ providers: OpenAI (GPT-4o, GPT-4o mini), Anthropic (Claude 3.5 Sonnet, Haiku), Google (Gemini), Groq, DeepSeek, Mistral, Together AI, OpenRouter, xAI (Grok), Fireworks, Perplexity and DeepInfra. You bring your own API key.

Is Yapzy safe? Does it collect my data?

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. The getyapzy.com marketing site itself uses standard analytics, which are fully disclosed on the privacy page.

Does Yapzy work in languages other than English?

Yes. Yapzy generates replies in 60+ languages. It will automatically detect the language of the post you're replying to, or you can set a preferred language in settings.

Is Yapzy against Twitter, LinkedIn, YouTube, Reddit, TikTok or Threads' terms of service?

Yapzy is designed to keep you in control: it generates reply text 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.

How much does Yapzy cost?

Yapzy is free for your first 50 replies. Unlimited Pro is a one-time $19 payment — not a subscription. There are no hidden fees. You also pay your AI provider directly for API usage, which typically costs pennies per reply.

Privacy Policy

The short version

The Yapzy Chrome extension itself is local-first. It runs entirely in your browser — there is no Yapzy server, no Yapzy database, no extension telemetry, and your API key never leaves your machine to anything other than the AI provider you chose. Your replies are not logged anywhere by us.

This marketing website (getyapzy.com) is separate. Like most software-product sites, it uses standard third-party analytics so we can see which pages convert. Those tools are listed below in full, with what each one collects and how to block them.

What Yapzy stores

All data is stored locally in your browser using Chrome's built-in storage. This includes:

Your API key for your chosen AI provider
Your selected AI model and provider
Your language preference
Your optional bio/context (used to personalize replies)
A reply counter (to track free tier usage)
Your license key (if you upgrade to Pro)

This data never leaves your browser except as described below. You can clear it at any time by removing the extension.

What leaves your browser

Yapzy makes two types of external requests:

1. AI reply generation

When you generate a reply, the text of the post you're replying to and your selected tone are sent directly from your browser to your chosen AI provider (e.g., OpenAI, Anthropic, Google, etc.) using your own API key. Yapzy does not proxy, intercept, or store these requests. The data handling is governed by your AI provider's privacy policy.

2. License validation (Pro users only)

If you have a Pro license key, Yapzy validates it with Polar.sh (our payment provider) every 7 days. Only your license key is sent. No personal data, usage data, or browsing data is transmitted.

What the Yapzy extension does NOT do

The extension does not phone home to any Yapzy server (there isn't one)
The extension does not send telemetry, page-view pings, or usage analytics
The extension does not track your browsing history
The extension does not store or log your generated replies anywhere outside your own browser
We do not sell or share any data

These statements describe the extension only. For what the marketing site (getyapzy.com) uses, see the next section.

Third-party services on this website

The marketing site you're reading right now uses three third-party services. None of these run inside the Yapzy extension — the extension stays local-first as described above. We use these tools on the website to keep the site accountable: chat so you can reach us, analytics so we know what people read, and session recordings so we can fix broken pages.

Tawk.to — live chat. Loads from embed.tawk.to. Sets cookies and records your IP, browser user-agent, page URL, and (if you open a chat) the chat content. Governed by Tawk's privacy policy.
Google Analytics 4 — page-view and event analytics. Loads from googletagmanager.com with property ID G-D6K72C8NPH. Sets cookies and records page URLs, referrer, device category, approximate geographic region (derived from IP; GA4 truncates and discards full IP by default), and standard events. Used to understand which pages bring readers in and which lose them. Governed by Google's privacy policy.
Microsoft Clarity — session replay and heatmaps. Loads from clarity.ms. Records anonymous session recordings (mouse movement, clicks, scroll position) and aggregates them into heatmaps. Clarity masks form inputs by default; it doesn't see anything you type. Sets cookies and assigns a per-visit ID. Governed by Microsoft's privacy statement.

If you don't want any of this running:use an ad-blocker (uBlock Origin blocks all three out of the box), turn on Brave's built-in tracker shield, or disable JavaScript — every page on this site is statically rendered and reads fine without it.

What these tools never see: anything inside the Yapzy extension. They run only on the public getyapzy.com pages; they have no way to reach into your extension settings, your API key, or the replies you generate.

Permissions

Yapzy requests the following Chrome permissions:

Storage — to save your settings and API key locally
Scripting — to add the Yapzy button to social media pages
Host access to social platforms(Twitter/X, LinkedIn, YouTube, Facebook, Instagram, Threads, Reddit, TikTok) — to inject the reply button into comment boxes and read the post you're replying to
Host access to AI providers(OpenAI, Anthropic, Google Gemini, Groq, Together, Mistral, DeepSeek, OpenRouter, xAI, Fireworks, Perplexity, DeepInfra) — to send reply-generation requests directly from your browser using your own API key
Host access to Polar.sh(api.polar.sh, buy.polar.sh) — to validate Pro license keys and process one-time purchases
Host access to raw.githubusercontent.com— to fetch the latest list of supported AI models without shipping a new extension update

Third-party services

Yapzy integrates with AI providers (OpenAI, Anthropic, Google, Groq, Mistral, DeepSeek, and others) and Polar.sh for license management. Each of these services has its own privacy policy. Yapzy sends the minimum data required for each service to function.

Disclaimer

Yapzy is not responsible for how third-party AI providers handle the data sent to them via your API key. By using Yapzy, you acknowledge that AI-generated content is sent to and processed by your chosen provider under their terms. We are not liable for any data processing, storage, or breaches by these third-party services.
