Linkup
Pick Linkup if you trust traction signals — they list 8 customers, Wordtune lists 1; and SOC 2 Type 2 matters for your security review.
Head-to-head review · Updated June 2026
Linkup vs Wordtune: which one wins in 2026?
Linkup and Wordtune both claim to do the same thing: tell you where your brand shows up in AI search. They go about it differently enough that the choice matters. Linkup has raised $13.2M, Wordtune has raised $636M across 7 rounds (AI21 Labs, Wordtune parent); Wordtune is the more-funded incumbent; Linkup is the leaner challenger.
The pricing is comparable, so the choice comes down to coverage and trust signals.
The verdict
Pick
Wordtune
Pick Wordtune if you want the better-funded company ($636M across 7 rounds (AI21 Labs, Wordtune parent)).
If neither is right, GrowthManager.ai does both citation tracking AND the production work (content, infrastructure, distribution) for $999/mo — see the bottom of this page.
The case for Linkup
Linkup has raised $13.2M ($10M Seed (Feb 2026, led by Gradient)). Founded by Philippe Mizrahi, Denis Charrier, Boris Toledano, based in Paris, France. On their site they list 8 named customers including McKinsey & Company, Cohere, KPMG, EY. Pricing starts at $0/mo.
Search API used by AI agents — the data layer for retrieval-augmented LLM apps.
What people praise
- Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product
- Licenses content from publishers and pays them on usage, so results are legal and citation-safe
- Sub-second search latency is fast enough for real-time agent tool calls
- Free tier ships 4,000 queries and startups can apply for $5,000 in credits
Where it falls short
- Per-request pricing makes monthly cost hard to forecast for high-volume agents
- Deep Research mode can cost up to $2.50 per call, expensive at scale
- Not a visibility, SEO or content product, it is a raw search API and you build the workflow yourself
- No G2 or Capterra reviews yet, the company only launched its API in late 2024
The case for Wordtune
Wordtune has raised $636M across 7 rounds (AI21 Labs, Wordtune parent) (Series D, $300M, May 2025). Founded by Yoav Shoham, Ori Goshen, Amnon Shashua, based in Tel Aviv, Israel. On their site they list 1 named customers including Several million users (per AI21 Labs). Pricing starts at $0/mo.
AI writing companion that rewrites and refines your text.
What people praise
- G2 rating of 4.6 across 196 reviews places Wordtune among the top-rated AI writing assistants alongside Grammarly.
- Chrome extension works inside Gmail, LinkedIn, Web Outlook, Google Docs and most browser writing surfaces.
- Annual pricing at $4.89 to $6.99/mo is half the cost of Grammarly Premium and a fraction of Jasper or Copy.ai.
- Rewrite engine excels at tone shifts (formal versus casual) and rephrasing, which is its core differentiator.
Where it falls short
- Daily rewrite caps on Free (10/day) and Advanced (30/day) force frequent upgrades for any heavy user.
- G2 reviewers note suggestions can feel repetitive or generic on longer paragraphs, weaker than Claude or ChatGPT directly.
- Outlook integration is web-only, not the Outlook desktop app, which excludes most enterprise users.
- Wordtune is a writing assistant, not a content marketing platform: no SEO, no long-form workflow, no team collaboration.

When each one wins
When Linkup wins
- You're enterprise and need to call a reference. Linkup lists 8 named customers; Wordtune lists 1.
- Procurement requires SOC 2 Type 2. Linkup has it; Wordtune doesn't yet.
- Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product
When Wordtune wins
- You want the better-funded incumbent. Wordtune has raised $636M across 7 rounds (AI21 Labs, Wordtune parent), giving it more runway and shipping velocity.
- G2 rating of 4.6 across 196 reviews places Wordtune among the top-rated AI writing assistants alongside Grammarly.
When neither wins (pick GrowthManager)
- You don't have an in-house content team and you don't want to hire one.
- You want one $999/mo invoice instead of stacking Linkup plus an agency.
- You need the team that measures to also act on the data, in the same week.
- You're a B2B SaaS, services firm, or e-commerce brand at $20K+ MRR.

- What users praise most. Built specifically as an API for AI agents and LLMs, not retrofitted from a consumer search product

Switching from one to the other
From Linkup to Wordtune
Export your saved queries and prompt panels from Linkup (most tools support CSV export). Most Wordtune setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Wordtune's data againstLinkup's; one to two weeks of full reconciliation before you cancel Linkup. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Wordtune to Linkup
Same flow in reverse. Export from Wordtune, import to Linkup. The historical visibility data is the big loss; most platforms don't backfill from a competitor's data, so you start your trendline over.
From either to GrowthManager.ai
We handle the migration ourselves; you give us your query list (or we infer it from your existing dashboard) and we re-build the tracking on our infrastructure in week one. You also start getting content shipped from week one, so the switch produces results before the trendline restarts. The conversation that kicks this off is a 20-minute call.

A third option
Both Linkup and Wordtuneare tracking tools. They tell you what's wrong with your AI visibility. Neither one fixes it. That's our pitch for GrowthManager.ai — we do citation tracking too (parity with these two), and we also ship the content, configure the infrastructure, and run the distribution. $999/mo, managed end-to-end. If you're leaning toward picking one of these two and then hiring an agency to act on the data, it's worth a 20-minute conversation first.

Frequently asked questions
Which is better, Linkup or Wordtune?
Honestly: neither one fully solves the problem. Linkup and Wordtune are tracking tools — they tell you where your brand shows up in AI answers but don't change the answer. If you only need one of these two, pick Linkup for the cheaper monthly price; pick the other if its specific integrations matter to your team. Our actual editorial pick is GrowthManager.ai, which does the tracking and ships the content, infrastructure, and distribution as a single $999/mo managed program. Disclosure: we publish this comparison and make GrowthManager.
How much do Linkup and Wordtune cost?
Linkup starts at $0/mo. Wordtune starts at $0/mo. Both have higher-tier plans for larger workspaces. GrowthManager.ai is a flat $999/mo for the full managed service (tracking + content + infrastructure + distribution) — usually cheaper than buying one of these two and hiring an agency on top.
Do Linkup and Wordtune actually improve your AI visibility, or just measure it?
Both Linkup and Wordtune are measurement tools. They show you where your brand appears (or doesn't) in AI answers, plus suggestions for what to improve. Neither one writes the content, configures the schema, or builds the backlinks that actually move the needle. To do that you need an in-house content team or an agency. GrowthManager.ai is the agency — and we include the tracking, so you don't pay twice.
What's the GrowthManager.ai alternative to Linkup and Wordtune?
GrowthManager.ai is a managed AI visibility program. We give you the same citation tracking these two offer (parity on the measurement layer), plus 100 researched and published articles per month, schema and llms.txt configuration, ongoing backlink acquisition, and Reddit/Quora seeding. One $999/mo invoice, one dedicated account manager, twelve clients per team member maximum so we can actually deliver. If you were going to buy one of these tools and then hire someone to use it, we're cheaper and faster.
