How it works

You only do the first two

You already do them every day. Before, the browsing evaporated. Now it stays.

1

Search

Set the filters as prompted and scroll. The panel counts how many notes are still needed.

2

Open

Open a few notes to read. 15 on Xiaohongshu, 6 on Douyin is enough; the panel keeps count for you.

3

Get the brief

Everything else is automatic. What comes out is a brief you can hand straight to whoever shoots.

What's in the report

That viral post —
can you actually copy it?

Spotting what went viral is easy. Knowing whether you can get in is the hard part.

SectionThe question it answers
Template libraryContent that genuinely blew up recently, broken into patterns you can reuse
Rising signalsTopics just starting to move, not yet worn out by copycats
Keyword diagnosisSome keywords look busy but are propped up by big accounts. On “supplements” the top 10% of notes took 74% of likes and half got under 100. A new account should stay away
Engagement structure100k likes driven by shares and 100k driven by saves are two different things. Copy the wrong one and the shoot is wasted
Search intentWhat people type into search engines around the keyword. “Can I take liver pills long-term” and “which liver pills are good” call for completely different videos

It comes down to one thing

What to shoot next. No charts you can't read. Each topic gets three lines: what to make, roughly what the cover looks like, and why it can work.

Spend the rest of the time shooting.

New

Video notes are captured too:
voice-over as text, key frames in the brief

Most winning posts are videos now, and a title plus a like count does not tell you why they work. Play a video note as you normally would and the side panel turns the voice-over into text and saves a few key frames. Both go into the brief next to the title and engagement numbers.

  • Shooting referenceWhat the first three seconds say, how the shots are ordered, when the product close-up appears. The brief lists it per video so you can check your own script against it.
  • Ad creative referenceOpening lines and selling-point order of the high-engagement videos, side by side, so you know which hook to test first.
  • Material breakdownFull voice-over text lands in the spreadsheet and is searchable. See how others phrase the same selling point.

Only videos you opened and played yourself are processed. Transcription is included in each run at no extra charge, and you can switch video capture off in Settings.

AI video · sample Coming soon

From the script in your brief plus product photos you provide, generate a short video: preview the direction before a real shoot, or use it as test creative for ads.

About AI-generated content
This sample uses a fictional blue ceramic mug and AI-generated product images, footage and voice. The website preview is watermarked and muted. When you publish or advertise with AI-generated video, add the labels required for your market and platform, and only use product photos you have the right to use.

Why it's built this way

Still usable next year

We write these down so you can use it with peace of mind.

You browse; you choose what to collect. We do not ask for your platform password, log in for you, or automate scrolling, clicking or posting. Compared with account handover or bulk scripted activity, this reduces credential exposure and automated-action risks. Third-party tools remain subject to each platform's rules; account status cannot be guaranteed.

Desktop edition: data never leaves your machine. You use your own AI keys; our servers never see your content.

Cloud edition: anonymised before upload. Author names and user IDs are stripped in your browser; we never receive them. Raw content is deleted after analysis; reports stay for 7 days.

We don't make another business out of your data. No merging, no resale, no model training. Analysed, then deleted.

FAQ

The questions you were going to ask

What is Infomelt and what does it do?

A browser extension for people who run content on Xiaohongshu (RedNote) and Douyin. You search a keyword, scroll and open notes exactly as you normally would; the side panel records what you saw — title, author, likes, saves, comments, body text — into an Excel with cover thumbnails. Submit it and about 20 minutes later you get a content brief: which directions are rising under that keyword, the title patterns that work, the 5 posts to make this week, and a side-by-side comparison of several keywords.

Will it affect my Xiaohongshu / Douyin account?

You browse and choose what to collect. The extension organises content already displayed on pages you open. It does not ask for your platform password, log in for you, or automate scrolling, clicking or posting. Compared with account handover or bulk scripted activity, this reduces credential exposure and automated-action risks. Third-party tools remain subject to platform rules; we cannot guarantee your account will not be restricted.

Which platforms and browsers?

Xiaohongshu (xiaohongshu.com) and Douyin (douyin.com) web versions. Desktop Chrome / Edge are recommended. Tested versions of Brave and Comet (macOS), and 360 Extreme X (Windows), passed basic checks and can use the manual package. QQ Browser is still being verified and is not recommended yet. Firefox, Safari and mobile browsers are not supported. The 360 checks apply to Extreme X only. TikTok support is on the roadmap.

How is this different from data platforms like Xinhong or Huitun?

Those sell site-wide rankings and market dashboards for hundreds to thousands of yuan a month. Infomelt only works on what you browsed yourself, and answers a concrete question — what to make next under the keywords you care about. Plans start at ¥39 for a weekly pass.

Where does my data go?

Everything stays on your computer by default; the Excel lands in your Downloads folder. Only when you click Cloud analysis is content uploaded, and author names and IDs are stripped in your browser before upload. Raw content is deleted as soon as the analysis finishes; reports stay downloadable for 7 days. We never merge, resell, or train models on your data.

Pricing? Can I try first?

Start with a weekly pass: ¥39 for 2 runs in 7 days. Monthly plans, billed per run: Small ¥188 for 10 runs, Large ¥328 for 20, XL ¥698 for 60. Pay for six months and one of them is free. Alipay and WeChat Pay accepted. One run is one full analysis of a batch, any number of keywords. Subscribe within 7 days of buying a weekly pass and its ¥39 is credited in full; one pass per account every 90 days.

How do I install?

Chrome Web Store or Microsoft Edge Add-ons — search “Infomelt” or use the buttons on this page. Other browsers listed as tested can load the manual package from this site. See the guide for tested versions and installation steps.
