Kagi
Pick Kagi if you want the cheaper option ($0/mo vs $140/mo).
Head-to-head review · Updated June 2026
Kagi vs Semrush: which one wins in 2026?
Kagi and Semrush 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. Kagi has raised ~$5.5M, Semrush has raised Acquired by Adobe for $1.9B (2026); Semrush is the more-funded incumbent; Kagi is the leaner challenger.
Kagi is cheaper out the gate, but that's not the only thing that matters. The right pick depends on which dimension matters most for you.
The verdict
★ Our pick
Pick
Semrush
Pick Semrush if you want the cheaper option ($140/mo vs $0/mo); and you trust traction signals — they list 6 customers, Kagi lists 1; and you want the better-funded company (Acquired by Adobe for $1.9B (2026)); and SOC 2 Type 2 matters for your security review.
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 Kagi
Kagi has raised ~$5.5M ($2.5M from 93 angel investors (2023-2024)). Founded by Vladimir Prelovac, based in Palo Alto, CA. On their site they list 1 named customers including 50,000+ individual paying members as of June 2025. Pricing starts at $0/mo.
Paid ad-free search engine with AI assistant.
What people praise
- No ads, no tracking, no sponsored content, the business model is funded by subscriber payments not data harvesting
- Lenses let you filter searches to academic, programming, recipes, or custom domain lists for cleaner results
- Block, boost, or bury domains like Pinterest at the personal account level so your results improve over time
- Question mark suffix triggers an AI summary of results at the top, useful for quick research without leaving search
Where it falls short
- Paying $10/mo for search feels unusual when Google is free, sticker shock is the most common reason to churn
- Starter plan caps at 300 searches, easy to blow through in a single research session
- Local business searches are weaker than Google Maps, fall back to Google for restaurants and directions
- Orion browser is Mac/iOS only, Windows and Linux users get Chrome and Firefox extensions instead
The case for Semrush
Semrush has raised Acquired by Adobe for $1.9B (2026) (Adobe acquisition closed April 2026). Founded by Oleg Shchegolev, Dmitry Melnikov, based in Boston, MA. On their site they list 6 named customers including Decathlon, Quora, Booking.com, Samsung. Pricing starts at $140/mo.
All-in-one SEO and content marketing platform with a growing AI search visibility module.
What people praise
- Largest SEO database in the category with 25B+ keywords and 43T+ backlinks per Semrush's own reporting.
- Toolset breadth is unmatched: keyword research, rank tracking, backlinks, site audit, content marketing, PPC, and social all in one.
- AI Overviews tracking and AI search visibility features were rolled out earlier than most legacy competitors.
- Sheer volume of integrations (HubSpot, Google, Wix, Zapier, Trello) makes it easy to wire into existing workflows.
Where it falls short
- Per-seat pricing is brutal: additional user seats cost $45 to $100/month each on top of the base plan.
- Add-ons like the Trends toolkit add another $289/month, so real-world cost is far above sticker.
- Pro plan has hard 500-keyword tracking limit, forcing upgrades long before features are needed.
- Site audit is capped per project and crawl, making it weaker than dedicated crawlers like Screaming Frog at scale.

When each one wins
When Kagi wins
- Budget is the constraint. Kagi starts at $0/mo vs Semrush's $140/mo, so on a per-seat basis it's the cheaper way in.
- No ads, no tracking, no sponsored content, the business model is funded by subscriber payments not data harvesting
When Semrush wins
- You're enterprise and need to call a reference. Semrush lists 6 named customers; Kagi lists 1.
- You want the better-funded incumbent. Semrush has raised Acquired by Adobe for $1.9B (2026), giving it more runway and shipping velocity.
- Procurement requires SOC 2 Type 2. Semrush has it; Kagi doesn't yet.
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 Kagi 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.
Reasons to pick one over the other
Reasons to pick Kagi over Semrush
- Lower entry price. Kagi starts at $0/mo vs Semrush's $140/mo.
- More plan flexibility. Kagi offers 4 pricing tiers vs Semrush's 3, so there's a better chance one fits your team size.
- Built for the LLM era. Kagi was founded in 2018, built around AI search from day one; Semrush dates back to 2008 and is retrofitting.
- What users praise most. No ads, no tracking, no sponsored content, the business model is funded by subscriber payments not data harvesting
Reasons to pick Semrush over Kagi
- Better-funded incumbent. Semrush has raised Acquired by Adobe for $1.9B (2026), giving it more runway and shipping velocity than Kagi (~$5.5M).
- More named customers. Semrush lists 6 customers vs Kagi's 1, including Decathlon, Quora, Booking.com.
- SOC 2 Type 2. Semrush carries SOC 2 Type 2; Kagi does not yet, which can hold up procurement.
- More verified reviews. Semrush has 3,434 G2 reviews vs Kagi's none on file, so the average rating carries more weight.
- More mature platform. Semrush (founded 2008) has had more time to harden the product than Kagi (2018).
- Wider integration ecosystem. Semrush integrates with 12 tools; Kagi ships 8.
- What users praise most. Largest SEO database in the category with 25B+ keywords and 43T+ backlinks per Semrush's own reporting.
Switching from one to the other
From Kagi to Semrush
Export your saved queries and prompt panels from Kagi (most tools support CSV export). Most Semrush setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Semrush's data againstKagi's; one to two weeks of full reconciliation before you cancel Kagi. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Semrush to Kagi
Same flow in reverse. Export from Semrush, import to Kagi. 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 Kagi and Semrushare 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, Kagi or Semrush?
Honestly: neither one fully solves the problem. Kagi and Semrush 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 Kagi 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 Kagi and Semrush cost?
Kagi starts at $0/mo. Semrush starts at $140/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 Kagi and Semrush actually improve your AI visibility, or just measure it?
Both Kagi and Semrush 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 Kagi and Semrush?
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.
