Shruti KaushikJasper Pro costs $69 a month, or $59 billed yearly, and is built for marketing teams: Brand Voices, knowledge assets, agents and a Canvas editor, with no LinkedIn scheduling. For one person on LinkedIn, Supergrow and ContentIn at $39 draft and schedule, Postiv adds a planning agent, Taplio adds outreach, and Copy.ai at $29 for 5 seats is the cheaper workspace. 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 Jasper alternative
Jasper is one of the oldest AI writing companies and now sells itself as a marketing platform. Pro gives one seat the Canvas editor, workflow agents, 2 Brand Voices, 5 Knowledge assets and 3 Audiences; Business is custom-priced for teams. LinkedIn writers look elsewhere because of the price, because Brand Voice is a managed setting the site does not say is derived from your own posts, and because there is no LinkedIn scheduling or calendar.

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 Jasper: Jasper flags tone that is off-brand; Klype flags figures with no source, invented scenes and machine patterns, and holds the draft to a voice measured from your own writing. Klype has nothing for campaigns, translation or bulk content.
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.
Copy.ai: a cheap team chat workspace
Copy.ai now calls itself a GTM AI platform. Chat is $29 a month for 5 seats with OpenAI, Anthropic and Gemini models, 20% less billed annually. Enterprise is custom-priced with workflows, Copy Agents, Infobase, API access and 20+ integrations, billed in credits. No free plan, trial or LinkedIn scheduling is stated on the pricing page.
Copy.ai is Jasper's closest rival in category and cheaper to start: $29 a month for 5 seats and three model families.
Best for: small teams who want a general multi-model chat workspace, or companies codifying sales and marketing workflows.
Supergrow: voice-matched drafts with scheduling
Supergrow drafts from a "Content DNA" profile built from your existing posts, then schedules with a calendar and an auto first comment. Engagement is suggested, never automated. Pro is $39 a month with a 7-day trial; Teams is $199 for employee advocacy.
Supergrow is what a single LinkedIn author usually wanted from Jasper: drafts from their own posts, a calendar, scheduling, at $39.
Best for: people who want drafting and scheduling in one tool without outreach automation.
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.
ContentIn plans a week of LinkedIn posts and publishes them through the official API, which is the part of the job Jasper never touches.
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 gives a LinkedIn-specific version of Jasper's agent idea: a planner that fills slots and drafts posts, carousels and infographics in a brand kit.
Best for: founders with plenty of source material who want a planner to turn it into a full calendar.
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.
Taplio is the all-in-one for LinkedIn, with AI writing from $69, the same price as Jasper Pro, plus scheduling, an engagement feed and automated 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 LinkedIn idea you would genuinely post this week. Draft it in Jasper's trial and in two of the trials above on the same afternoon.
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.
