Alto’s capabilities.

Work with campaigns, conversations, and customer insights from a compatible AI assistant.

Connect Meet Alto to Claude Code for me.

If a meet-alto server is already set up, keep it. Otherwise run:

claude mcp add --transport http --scope user meet-alto 'https://app.meetalto.ai/mcp'

Then tell me to run /mcp, choose Meet Alto and sign in. I’ll pick my workspace and approve access in the browser. Stop if sign-in fails.

Then read my Meet Alto workspace name and tell me what it is. If the tools haven’t loaded yet, tell me to start a new session. Don’t change anything in my workspace yet.

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.

  • Which mic is this? Sounds so clean 🎧

    • 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.

    • 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.

Replies that don’t read like a bot

Skip the emoji and one-word comments, and let replies go out gradually, the way you’d answer them yourself.

  • 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.

Know if YouTube holds your reply

YouTube sometimes holds replies it thinks are spam. Alto checks after posting and tells you, instead of calling it sent.

YouTube comment automation FAQs

Have something else in mind?
Talk to the Alto team.

What can Alto do on YouTube?

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.

Can Alto DM people who comment on my videos?

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.

Can I approve replies before they post?

Yes. Drafts can wait in your inbox until you send or edit them. Once you trust Alto, let the replies it’s sure about post on their own, and the rest wait for you. Slack can let your team know when a draft is waiting.

Which comments does Alto reply to?

You choose: only comments that need an answer, like questions, buying interest and complaints, or every comment, and you can skip the emoji and one-word ones. Comments YouTube holds for review wait for your approval first.

Does it work with YouTube Shorts?

Yes. Comments on Shorts and regular videos arrive in the same inbox and get the same replies and moderation.

What happens when a comment is hidden?

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.

Can I manage YouTube alongside Instagram and Facebook?

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.

Will YouTube commenters become contacts in Alto?

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.

What access does Alto need to my channel?

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.

Can I start for free?

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. With UNLIMITED, you reply and moderate by hand from the inbox.
