Show up where people look
TikTok users who say they read comments, as a global average across eight surveyed markets. A relevant comment enters a surface people already inspect.
TikTok commenting from real US phones
Comments drafted by AI in your voice, or supplied verbatim through the API, posted onto any public TikTok video from physical devices. Randomized pacing, device-confirmed, proof screenshot on every one.
The comment is only the opening move.
Viewers open the comments to decide what they make of a video. The rows below follow one brand comment through that sheet.

Be present as the brand
Agree that brands posting or replying to comments feel like part of the TikTok community. For clearly identified brand accounts, fit and voice matter more than volume alone.

Enter the consideration layer
Read video comments to gauge community opinion about a product or brand after a creator ad. This shows where opinions form, not that a controlled comment becomes independent community opinion.

Let a reply extend the moment
Average engagement reported for proactive brand comments when the original creator replied. The analysis combines TikTok and Instagram, so treat it as directional rather than a TikTok-only guarantee.
What ships with commenting
Real US phones
Every comment posts through the TikTok app on a physical device in the fleet. No API bots, no emulators.
Voices
A reusable writing style: a prompt plus example comments. The AI drafts in your voice and learns from your feedback.
Monitors
Watch any creator. When a video crosses a view milestone, comments fire automatically.
Boost Post
Paste a link, edit the AI drafts inline, hit Boost. Nothing posts until you do.
API and MCP
Send exact text programmatically: up to 500 comments per request, status polling, signed webhooks. API reference.
How commenting works
Voice
Define the writing style: a prompt, example comments, and what never to post.
Watch
Monitors track creators and fire at view milestones. Or boost a single post by link.
Post
Each comment lands at its own random moment inside the posting window, from its own phone.
Prove
The device confirms every published comment and captures a proof screenshot.

Commenting questions, answered straight
TikTok only today. Instagram, YouTube, and Reddit appear in the picker but are disabled, and we would rather tell you that than sell you a checkbox.
Each comment posts at its own independent random moment inside a posting window, 5 minutes to 24 hours by default. A monitor in the dashboard can set its own window anywhere from 1 minute to 7 days; API requests can set theirs per request but never beyond 24 hours. Per-video caps and a minimum-existing-comments guard apply either way.
Yes. Any public TikTok post link works, including competitors' and creators' videos. Monitors watch any public creator and fire at view milestones.
Yes. POST /api/v1/comments with a bearer key posts your text verbatim, up to 500 comments per request, and the MCP tools do the same. Each request can set its own placement window, up to 24 hours. Text already queued or published on the same post is skipped rather than billed, so retries are safe. Status polling and signed webhooks report posted, failed, or blocked, and monitor membership is managed through the same API.
You are charged only when a comment actually posts. Queued, failed, and blocked comments are never charged, and monitors auto-pause at zero balance.
Published means the device confirmed it, and every published comment has a device-captured proof screenshot in the Activity tab. If TikTok later removes it, the screenshot is the record.
It retries automatically on a different device after a short randomized delay, on up to 3 distinct devices, before it is marked Failed. Failed comments are never charged.
doublespeed also runs device-native posting networks on TikTok, Instagram, Facebook and YouTube
