SuperX is a broader OS. CometX is the loop you approve.
SuperX’s public site (September 2026) packages discovery, writing, scheduling, engagement, and analysis, sells automations, and offers a Chrome extension. If you want that surface area, buy SuperX.
Buy CometX if you want to stay on X’s official API, draft from your own work, and never let software speak to a stranger for you. Creator is $29/mo. You approve every word.
A wide workflow plus advertised automations and an overlay in the Chrome store (10,000 users, 4.2/5 from 55 ratings, version 0.8.11, updated 18 September 2026).
Your voice, your data, your timing. Every reply to someone else is one you approved. Nothing sends itself to a stranger. When you are going fast enough to look automated, it says so.
SuperX figures below are from their public pricing, FAQ, Chrome listing, and founder posts as of September 2026. We did not enter the paid app. If they moved a number, the jobs below are still the comparison.
| Job | SuperX | CometX |
|---|---|---|
| What it is | A creator workflow that packages discovery, writing, scheduling, engagement, and analysis, plus advertised automations and a Chrome overlay. | X-only growth loop. Voice, peak window, daily plan, sized reply openings. No extension. |
| Whose words | Public product copy includes inspiration and remix. The September 2026 scorer launch says the paid engine uses the customer’s own posts; the free tester uses a population baseline. Launch thread. | Your own best posts. It refuses to learn from AI drafts you never edited. |
| Replies to strangers | Advanced advertises 750 engage replies a month; Ultra advertises 3,000. Public pricing. We have not used the paid Engage product. | We draft. You send. A send-all button is out of scope — volume replying is how accounts earn labels. |
| DMs and agents | Developer docs cover signal agents. Automations are advertised on the public site. | No auto-DM. Nothing sends itself to a stranger. That is a product rule, not a platform guarantee. |
| When you look automated | Not independently verified from public pages. | Near-dupe drafts get rewritten before you see them. A burst inside one hour is named while you can still slow down. |
| Evergreen | Public pages advertise scheduling and related workflow tools. | A repeat is a rewrite, never the same text twice. |
| Links | You decide. | Links allowed: X's published ranking code doesn't penalise them. A bare link gets a nudge to add context, and one click moves a link to the first comment if you want it there. |
| Scoreboard | Public Tweet Tester (September 2026) returns a 0–100 score with contributing factors. Founder-reported pairwise accuracy is about two in three; that is not probability calibration. | Historical comparison against your own posts of the same format. Sample size and basis are the honest limit. No claimed forecast interval. |
| API | Official X API. Public developer docs also cover content, audience, analytics, scheduling, articles, and signal agents. | Official X API. No scraping, no unofficial endpoints. Narrower tool set today. |
| Price (typical plan) | Public pricing, September 2026: Pro $49/mo (5 accounts, 500 posts). Advanced $99 listed, $49 launch (750 posts, 750 engage replies). Ultra $199 (10 accounts, 3,000 posts). A free trial is advertised; duration is not stated in the fetched FAQ. | Creator $29/mo. 3 accounts · 92 posts / mo shared. Hard spend ceiling. The number on the tin is the bill. |
| Cancel | Refunds are described as case-by-case, with contact within seven days (pricing FAQ). We do not have a representative review corpus for SuperX billing. | One-click cancel when billing is live. Keep the period you paid for. |
- Auto-DM, bulk DM, or a send-all on replies to strangers.
- A library of other people’s posts as claimed personal experience.
- A score presented as a calibrated probability without a measured calibration.
Is CometX a SuperX clone?
No. SuperX is a broader growth OS with a Chrome extension, advertised automations, and a public scoring demo. CometX is the loop that turns your own work into a post you approve. We will not ship auto-DM or a send-all on replies to strangers.
Does CometX auto-send replies or DMs?
No. Nothing sends itself to a stranger. AI drafts; you click send. That is our product rule. Human approval is a control in the app, not a promise about how X will treat the account.
Does SuperX use my own posts for scoring?
Rob Hallam’s September 2026 launch thread says the free tester uses a population baseline and the paid engine uses the customer’s own posts. CometX still refuses to learn voice from AI drafts you never edited.
What does CometX cost?
Creator is $29/mo for 3 accounts and 92 posts a month shared. Pro is $59. Agency is $149. Every plan is built to start with a 3-day trial. Post caps exist because X bills per write. We do not hide that.
