this channel is the reason I finally started filming
Comments YouTube holds for review or flags as likely spam show up in Alto with a clear label. Approve the real questions and answer them, or hide the rest.
Saving this for my desk makeover
The bounce-off-the-wall trick 🤯
Set rules for scam links, phone numbers, abuse or your own keywords, and Alto hides matching comments on the channels you allow. Banning someone is always your call.
YouTube comments sit beside your other channels’ comments and DMs, so your team can assign and answer in one place.

How far is the lamp from the wall?
About an arm’s length, angled up.
🔥🔥🔥
Would this work for a podcast?
Yes, just move the mic closer.
YouTube sometimes holds replies it thinks are spam. Alto checks after posting and tells you, instead of calling it sent.

Alto brings comments from your videos and Shorts into your inbox, answers them in your voice with AI, works through the comments YouTube holds for review or flags as spam, and hides comments that match your moderation rules. YouTube has no DMs, so comment-to-DM campaigns, sequences and AI DM agents aren’t available on this channel.
No. YouTube doesn’t let channels message viewers privately, so Alto answers in a public reply under the video. Its replies never ask viewers to DM you.
Yes. With You approve every reply, drafts wait in your inbox until you send or edit them. With Auto-send when confident, replies that clear your confidence bar post on their own and the rest can wait as drafts. Slack can let your team know when a draft is waiting.
You choose: only comments that need an answer, like questions, buying interest and complaints, or every comment. You can skip emoji-only, one-word and mention-only comments, and replies inside threads. Alto only replies to comments posted after you connect, and never to comments YouTube is holding until you approve them.
Yes. Comments on Shorts and regular videos arrive in the same inbox and get the same replies and moderation. Alto doesn’t set separate rules for Shorts.
It disappears from your video, along with the replies under it. Automatic hiding only runs on channels where you’ve switched it on, and banning someone is always your call.
Yes. YouTube comments arrive in the same inbox as your Instagram, Facebook, TikTok and WhatsApp conversations, so your team can assign and answer them in one place, with the same knowledge and brand voice.
No. YouTube doesn’t share commenters’ contact details, so Alto keeps their comments in your inbox but doesn’t add them to your contacts or email lists.
Sign in with the Google account that owns your channel and pick the channel you want to connect. Alto reads your comments and video titles, posts the replies you approve and hides what breaks your rules. It only posts or hides on its own once you switch that on.
You can create a free Alto account, but adding a YouTube channel needs Pro or the one-time UNLIMITED package. AI replies and automatic moderation are part of Pro and use its monthly AI Credits. With UNLIMITED, you reply and moderate by hand from the inbox.

A viewer asks. Alto knows which video they mean.
Comments from your videos and Shorts land in one inbox, each beside the video it came from. Alto picks out the ones that need you: questions, buying interest and complaints.

It’s a dynamic mic on a $12 desk arm, about a hand’s width from my mouth. That does most of the work 🎙️
The answer comes from what you’ve taught it.
Alto replies in your voice from your website, notes, files and Shopify products, with the video’s title and thumbnail for context. Replies it isn’t sure about can wait for you as drafts.

It does! I filmed this one at night. Bounce the lamp off a white wall and keep it just out of frame.
You approve it, or let the sure ones post.
Start by approving every reply, with a Slack ping when one is waiting. Once you trust it, let confident replies post on their own, a few minutes apart. Your edits teach Alto your tone.

Ordered the same arm after this, thank you!
One good answer helps the next viewer too.
Your reply stays public under the video, so the next person with the same question finds the answer already there instead of asking again.
