This video completely changed how I approach editing. Do you use the same method for your Shorts too?

✦ AI suggestions — in your voice
Yes! Same approach for Shorts — I actually break it down in my editing series. Check the playlist!
Yep, it scales perfectly. Shorts just need tighter cuts in the first 2 seconds.
Honestly yes, but Shorts punish slow intros way harder so the first cut is everything.

How It Works

Three steps. That's it.

Vidtopia fits into your existing YouTube workflow without changing how you operate.

1

Click Suggest

A button appears next to every comment on YouTube and YouTube Studio. Click it and Vidtopia reads the comment, video context, and your voice profile.

2

Pick a Reply

Three AI-generated suggestions appear — written in your style, not generic output. Tap the one that fits or tweak it before using it.

3

You Click Submit

Vidtopia fills the reply box. You read it, edit if needed, then press the official Reply button. You are always in control.

Features

Everything a creator needs
to run their comments.

Built for the real workflow — not the ideal one.

🎭

Persona Voice Matching

Export your past comments with yt-dlp, import as a persona dataset. Suggestions start sounding like you actually wrote them — not a generic AI.

⚡

Instant Suggestions

3 tailored reply options generated in seconds. Results are cached for 72 hours so repeat comments don't burn your API credits.

📊

Real Engagement Rate

See your true engagement rate (Likes ÷ Views) overlaid on every video — not the vanity metrics YouTube hides behind in its dashboard.

🏷️

One-Click Tag Extraction

Copy all video tags to clipboard instantly. Useful for SEO research, competitor analysis, and building your own keyword library.

🌐

Multi-Channel + Anti-Detect

Built for AdsPower and BitBrowser operators. Each profile has its own isolated settings — zero cross-channel leakage, ever.

🔒

100% Local Storage

All settings, persona data, and caches live in your browser profile only. No cloud, no accounts, no telemetry. Full stop.

Who It's For

Built for every type
of creator operation.

🎬

The Solo Creator

10K – 100K subscribers

Your comment section is growing but your time isn't. Stay present with your community without spending 2+ hours a day in the replies.

📡

The Multi-Channel Operator

2–5 channels, anti-detect setup

Running multiple profiles in AdsPower or BitBrowser? Vidtopia works per-profile with complete isolation. No data leaks between channels.

🏢

The YouTube Agency

Managing creator accounts

Load each creator's comment history as a persona dataset. Every reply suggestion matches that creator's unique voice — not a shared template.

Why It's Safe

AI-Assisted.
Human-Executed.

Bots get flagged because they make automated HTTP requests to YouTube's servers. Vidtopia never does that — not once.

  • No automated clicks — you always press the Reply button
  • No HTTP requests to YouTube — only your LLM provider is called
  • No credentials stored outside your browser profile
  • Technically identical to typing the reply yourself
  • Safe inside anti-detect browser profiles

FAQ

Common questions

Vidtopia is a free Chrome extension that generates AI-powered comment reply suggestions for YouTube creators. It uses a "click-to-fill" model — the AI prepares personalized options based on your voice and the comment context, but you always click Submit. Zero bot risk, no automated requests to YouTube's servers.
Yes. The extension never makes automated HTTP requests to YouTube or clicks buttons on your behalf. It fills the text field with a suggested reply — exactly like autocomplete. You read it, edit if needed, and press the Reply button yourself. That's legally and technically indistinguishable from typing it manually.
Yes. Vidtopia is designed for multi-channel operators running AdsPower, BitBrowser, or any Chromium-based anti-detect browser. Each browser profile maintains its own isolated settings and persona data — zero cross-channel leakage.
Export your past YouTube comments using yt-dlp and import them as a persona dataset in the extension popup. Vidtopia uses this data to generate suggestions that match your speaking style, vocabulary, and tone — not generic AI output.
None. All data — settings, persona datasets, reply caches — is stored locally in your browser profile using Chrome's local storage APIs. There is no cloud sync, no telemetry, and no account creation required. Your data never leaves your machine.
Any Chromium-based browser (Chrome, Brave, Arc, Edge, or anti-detect browsers) and an API key from an OpenAI-compatible LLM provider — OpenAI, Anthropic, DeepSeek, Aliyun DashScope, or a locally hosted model all work.
Yes. Vidtopia is free and open source. You only pay for your own LLM API usage, which is typically fractions of a cent per suggestion batch.
