Shruti KaushikSupergrow's closest replacement is ContentIn, also $39 a month, which plans your week and publishes through LinkedIn's official API. Postiv adds a planning agent, AuthoredUp is the cheapest editor at $19.95, LinkGenie starts at $19 with a free plan, and Taplio adds outreach automation. Klype AI, at $39, measures your voice from your own posts and checks every draft for unsupported claims before you publish.
Why people look for a Supergrow alternative
Supergrow does its job without drama: a "Content DNA" profile from your existing posts, drafts, a calendar, an auto first comment and suggested engagement you act on yourself. Pro is $39 a month with a 7-day trial. The reasons to look elsewhere are specific: a week planned for you rather than a calendar to fill, a cheaper tool if you write your own drafts, outreach automation that Supergrow deliberately does not run, or a check on what the drafts claim, which its site does not describe.

Klype AI: if credibility matters more than volume
Klype is our product, so weigh this section accordingly. It keeps one record of your product, buyer and plan, measures your voice as numbers from your own posts, and its Check scores any draft, including one from ChatGPT, for figures with no source, invented stories and machine-writing patterns before you post. $39 a month; the 7-day trial charges nothing until day 8. The checks are free at klype.ai/check.
Against Supergrow: both start from your past posts. Supergrow builds a profile and drafts from it; Klype measures rhythm, fragments, punctuation and contractions as numbers, holds drafts to them, and then scores the draft for claims that will not hold. Supergrow has scheduling and Klype does not.
Where it falls short: it launched on 1 October 2026, so its track record is short, and it does not schedule or post.
Best for: founders and consultants who write under their own name and care that every claim holds up.
ContentIn: a done-for-you weekly plan
ContentIn plans your week, drafts from a "Voice DNA" built from a profile import, an interview, your posts and your edits, and publishes through LinkedIn's official API. Growth is $39 a month; Pro at $59 adds a light leads view. The 7-day trial asks for a card, with a 30-day refund on the first payment.
This is the most direct swap.
Best for: founders who want a weekly plan handed to them and posts sent on schedule.
Postiv: a planning agent that fills the calendar
Postiv is built around Bob, a planning agent that suggests one idea per slot from your content pillars, sources and last week's results, then drafts posts, carousels and infographics in your brand kit and publishes through the official LinkedIn API with approvals. Public pricing is annual only: Creator Pro at $594 a year, shown as $49.50 a month, with a 7-day trial; its AI-instructions file lists $99 monthly. Admins can turn on team likes.
Postiv goes further on planning and formats: an agent fills every slot and drafts carousels as well as posts.
Best for: founders with plenty of source material who want a planner to turn it into a full calendar.
LinkGenie: the budget option
LinkGenie (linkgenie.one, not the unrelated linkgenie.co) is metered by posts. The free plan gives two posts with no card. Starter is $19 a month for 50 posts; Pro is $26 for 200 and adds scheduling, analytics, trend research and a Chrome extension; Premium at $36 removes the cap. It learns your voice from pasted posts or a questionnaire.
LinkGenie Pro at $26 covers drafting, scheduling and a Chrome extension with a 200-post cap, which is enough for most people posting a few times a week.
Best for: people who post a few times a week and want a fast first draft to edit at the lowest price.
Taplio: the all-in-one, if you accept automation
Taplio bundles AI writing, scheduling, an engagement feed and outreach. By its own pricing guide the Starter plan is $39 a month but AI writing starts on the $69 Growth plan, and the Pro plan can auto-send connection requests and follow-up DMs.
The upgrade path if you want Supergrow plus outreach.
Best for: people who want writing, scheduling and outreach in one place and are comfortable with automation on their account.
How to choose in one afternoon
Write one rough idea you would genuinely post this week and run it through two or three of the trials above, Supergrow included if you still have access.
Judge the drafts on two questions: does it sound like you, and does every claim hold up? Paste each into the free post checker to compare them on the same rules. The tool that needs the fewest corrections is the right one.

What is the best Supergrow alternative?
ContentIn is the closest like-for-like swap at the same $39 price, with a planned week and publishing through the official LinkedIn API.
