Will the replies sound like a bot?

No — you configure your tone, channel context, and custom instructions. The AI reads each comment individually and writes a reply that fits. Most viewers can't tell the difference.

Is it safe for my YouTube channel?

Yes. Replai uses the official YouTube Data API v3 with OAuth authorization. It only posts replies — it never deletes, edits, or modifies anything on your channel.

What if I don't like a reply before it goes out?

You can enable "Approval mode" in your rules. Any reply matching that rule goes to a pending queue for you to review before posting.

How many comments can it reply to?

Free plan: 50 replies/month. Starter: 400/month. Pro: unlimited — no caps, no slowdowns.

Does it work for any YouTube channel size?

Yes. It's useful from 100 subscribers (start building habits early) to 500,000+ (where manual replies become impossible).

Can I cancel anytime?

Yes, no contracts. Cancel from your account settings in one click.

The problem

The daily frustration every creator knows

Hours lost every week

Replying manually to 200+ comments takes time you don't have. So you don't. And the algorithm notices.

Engagement drops quietly

YouTube rewards creators who reply. Every unanswered comment is a missed signal to the algorithm.

Growth left on the table

Loyal viewers become fans when you reply. Ignoring comments means leaving retention and revenue on the table.

How it works

Three steps to autopilot

Step 1

Connect your channel

One-click OAuth. Replai reads unanswered comments automatically.

Step 2

AI writes the reply

Picks tone, context and language. Filters spam and one-word comments.

Step 3

You approve or auto-post

Review in Preview mode or let Auto mode handle everything.
