The best AI writing tools for LinkedIn.

Supergrow is the value pick and the most visible tool in this lane. Its voice capture is a genuine strength: rather than only ingesting posts, it runs 'PostCast,' an adaptive AI interview that pulls your vocabulary, tone, opinions, and topics into a 'Content DNA' profile, which is a smart way to bootstrap voice for people who have not posted much yet. Around it sits drafting, scheduling, repurposing, and carousel and infographic makers, so it covers the whole LinkedIn loop cheaply.

Pricing is public and low: $19/mo Starter, $39/mo Pro (unlimited PostCast, carousels, analytics), $139/mo for a 4-account Teams plan. It advertises a strong G2 average, but the review count behind it is small (on the order of a dozen), so read the rating as an encouraging early signal rather than settled proof, and do not weigh it against a tool with thousands of reviews.

The gaps versus the top of this list are two. It is LinkedIn-only, so it does nothing for Twitter, and while its voice capture is real, it does not show you a per-draft match read, so you are trusting that 'Content DNA' worked without a signal to confirm it on each post. For a budget-conscious LinkedIn-only creator, it is still the strongest starting point in the category.

ContentIn's angle is improvement over time. It trains a personal model on your profile and past posts plus an onboarding interview, then refines from your edits, so its drafts should drift closer to your register the longer you use it. That week-over-week claim is ContentIn's own and not independently tested, but the learn-from-your-edits loop is a real feature. Around the writer it wraps scheduling to profiles and company pages, an idea manager, carousels, analytics, and a 1,000+ template library.

Pricing, from the live site, is Growth $39/mo ($31 annual, one profile, 12 AI drafts a month) and Pro $59/mo ($48 annual, company pages, higher AI usage), with a custom agency tier and no free plan (a 7-day trial plus a 30-day refund). It carries a verifiable 4.7/5 from 82 reviews on Capterra (mirrored on GetApp).

It is a competent, adaptive ghostwriter for a LinkedIn-only workflow. The same two caveats recur: no Twitter, and no per-draft match read, so you trust that the model is learning your voice without a number confirming it on each draft.

LinkGenius is the closest thing in this set to VoiceMoat's scoring thesis, and it earns its ranking for it: it writes LinkedIn posts in your voice and then exposes a per-post score with a one-click 'magic refine,' so you get a number and a next action rather than a black box. It pairs that with something the others lack, a built-in email-newsletter tool, so the content you write on LinkedIn can feed an audience you actually own off-platform.

Two honest caveats. First, the score's dimensions are unspecified and the feature is vendor-stated (the site blocked our automated checks), so treat it as a real but unverified capability, and note it is a post-quality score, not a voice-fidelity read. Second, pricing is murky: the vendor snippet shows roughly $19/mo Starter and a $29/mo main plan, but a third-party review lists custom-only tiers, so confirm the live pricing yourself before buying.

The list-building angle is the genuine differentiator. If your LinkedIn strategy is really an audience-ownership strategy, and you would otherwise bolt on a separate newsletter tool, having both in one place is convenient. Just go in knowing the score measures post quality, not how much the draft sounds like you.

ViralBrain is built around prediction. It analyzes viral patterns from top creators, personalizes to your profile, and then scores each draft 0 to 100 across hook, structure, value, CTA, and an 'authenticity' component, with specific suggestions to lift the number. For a creator whose goal is reach, that pre-publish signal is genuinely useful, and it pairs the score with a land-grab of 100-plus free tools.

The distinction that matters for this list: ViralBrain scores predicted virality, not voice fidelity. Its number tells you whether a post might travel, not whether it still sounds like you, and the site folds 'authenticity' into a virality score rather than measuring your voice against your own baseline. Those are different jobs, and conflating them is how a feed fills with high-scoring posts that all sound the same.

Pricing is €39/mo (Pro) and €69/mo (Premium), in euros, though the trial terms are inconsistent across its own pages (a 7-day €1 trial versus a 14-day free trial), so confirm before buying, and we found no verifiable third-party rating to cite. If your bottleneck is reach rather than voice, ViralBrain's score is a real tool. If it is sounding like yourself, a virality number will not tell you when you have drifted.

CiteVox owns a wedge nobody else in this set touches: credibility through sourcing. It turns a topic, a YouTube video, or a PDF into a LinkedIn post where the factual claims carry inline citations back to their sources, in a persona matched to your style. For consultants, analysts, and thought leaders whose authority rests on being right and being seen to be right, that is a real differentiator in a feed full of confident, unsourced takes.

It does not, however, show a score of any kind, so voice matching here is a claim rather than a visible read. Pricing is credit-based (one credit per post), starting with a free two-credit trial; its own page's structured data points to roughly $1.50 per credit and a Pro tier near $24.99/mo, but the visible prices render blank and third-party sources disagree, so verify the live tiers. A G2 product page exists but with no confirmable rating or review count.

Treat CiteVox as a specialist rather than an all-purpose writer. If your posts live or die on credibility and you want citations done for you, it is worth a look. If you want to see your voice matched, or you want scheduling and analytics in one place, pair it with a tool that provides those.

Oiti (at ghostwriting-ai.com) leans furthest into the autonomous-ghostwriter framing. It reads your LinkedIn profile and website to build a persona 'clone,' keeps long-term memory so it sharpens from your tone and style feedback over time, and adds a newsjacking agent and infographics, aiming to be a near-hands-off content engine for personal and company accounts.

Pricing is public and mid-market: Creator $49/mo and Pro $79/mo, with a 7-day trial. There is no independent rating we could confirm (the site shows user-count testimonials rather than a G2 or Trustpilot number), so we are not quoting one.

The 'clone' claim is the thing to weigh. It is an appealing promise, but it is exactly the kind of claim that benefits from a visible check, and Oiti does not show one, so you are trusting the resemblance without a per-draft signal. For someone who wants ghostwriting handled and is comfortable editing the output, it is a capable, higher-touch option; for someone who wants to verify the voice, it leaves that to your own eye.

RedactAI competes on price and throughput. It analyzes your profile details and last 100 posts to build a personal model, then generates drafts in your style at a volume and price point below almost everything else here. Its free funnel is generous, which makes it an easy, low-risk way to test whether AI drafting fits your workflow at all.

Pricing is public and cheap: Essential $11.90/mo (15 posts, 1 profile), Creator $24/mo (unlimited posts), Copywriter $66/mo (multi-profile, agency). Its impact stats (tens of thousands of creators, hundreds of thousands of posts) are self-reported marketing rather than independently verified, and we found no third-party rating to cite.

The honest read is that RedactAI is a strong cheap unblocker, not a precision voice tool. It will get on-style drafts on the page fast for very little money; it will not show you a match read, and at high volume the usual risk applies, that speed becomes a way to publish more posts that blur together. Use it to beat the blank page, then edit for the voice it cannot verify for you.

EasyGen's angle is data-driven hooks. It is built on performance data from top creators and claims to learn your tone, intensity level, and the kinds of examples you like, delivered mostly as a Chrome extension so it lives where you write. For creators who want their drafts shaped by what has actually worked on the platform, that grounding is a reasonable pitch.

The practical friction is pricing and scope. The official pricing page 404'd during research, and third-party sources put it around $59.99/mo (roughly $49.99 billed annually) with a small free-post allowance, so confirm the live number; at that price it is one of the more expensive tools in this set. It is also strictly LinkedIn-only, which reviewers flag as its main limit, and we found no verified rating.

It is a competent, speed-first drafter with a performance-data twist, best for someone who values fast hooks over precision voice control. As with the rest of this tier, there is no visible match read, so the voice remains a claim you verify by eye.

Jasper is the outlier here, and it belongs on the list because marketing teams genuinely use it for LinkedIn. It is a general AI content platform 'built by marketers for marketers,' with a Brand Voice feature: upload writing samples and Jasper analyzes and mimics the tone, with two voices on Pro and unlimited on Business. For a team producing content across email, blog, ads, and social from one place, that breadth is the draw.

It is priced and built for that team context, not for a solo LinkedIn creator. Pro runs $69/seat/mo ($59 annual), with a custom Business tier, and it has no LinkedIn-native scheduling, analytics, or algorithm awareness, and no LinkedIn voice-fidelity score. Its Brand Voice mimics samples but does not show you how closely a given draft matches.

Choose Jasper when LinkedIn is one channel in a wider marketing operation and a shared brand voice across many surfaces matters more than LinkedIn-specific depth. For a creator whose whole game is sounding like themselves on LinkedIn, a LinkedIn-native, voice-first tool higher on this list will fit better and cost less.
