LiquidUser vs SuperX
SuperX is a growth suite for people building an audience on X: scheduling, AI writing, analytics, an engagement feed, Signal Agents that score people against an ideal customer profile, automatic DMs, and a Chrome extension that works inside X.
SuperX grows your audience on X. LiquidUser finds the one person describing the problem your product solves.
Where each one is better
What SuperX does better
SuperX is inside X today. Its Chrome extension has 10,000 users and lets you reply without leaving X, and it drafts replies from your own posts, so they sound like you. It also schedules posts, shows analytics, finds leads through the people an account follows or the members of a list, and has a 99-tool MCP server. For X growth as a whole, it does much more than LiquidUser.
Pick SuperX if growing and monetising an X audience is the whole job and you want it done inside X.
What LiquidUser does that SuperX doesn't
- It tells you a person is describing the problem your product solves, not only that they fit a customer profile.
- It maps each conversation to the claim on your own site it matches, with the page it came from, so you can check the fit in seconds.
- Memory carries your corrections, competitors and known customers across days, so tomorrow's list starts from what you taught it today.
- It also reads Hacker News, where many developer-tool buyers describe their problems. SuperX reads X only.
- It never sends anything for you: no automatic DMs and no automatic replies. You post every reply yourself.

Questions
- Is SuperX a direct competitor to LiquidUser?
- Partly. Both help founders find people on X and draft replies they post themselves. SuperX is a full X growth suite built around your audience; LiquidUser is built around the problem your product solves, starting from your website.
- Does LiquidUser post to X for me?
- No. LiquidUser never posts, likes, follows or sends a DM. For an X post, the draft opens in X's own composer and you press Post. It never asks for permission to post on your account.
- Does LiquidUser search X?
- Yes, through X's official API, read only, and Hacker News. When our X read budget runs out, the scan says X is unavailable rather than guessing. The details are on our sources policy page.
- What do the two cost?
- LiquidUser has one plan at $49 a month, and the scan is free with no account. SuperX Pro and Advanced are both $49 a month and Ultra is $199, as listed on superx.so/pricing on 29 September 2026.
