Head-to-head review · Updated June 2026

OnCrawl vs Writesonic: which one wins in 2026?

OnCrawl and Writesonic 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. Writesonic is the more-funded incumbent; OnCrawl is the leaner challenger.

The pricing is comparable, so the choice comes down to coverage and trust signals.

The verdict
Pick

OnCrawl

OnCrawl is the right pick if your team prefers their approach and pricing fits.

Pick

Writesonic

Pick Writesonic if 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 OnCrawl

Founded by Francois Goube, Tanguy Moal, based in Bordeaux, France. On their site they list 10 named customers including Adidas, L'Oreal, Ticketmaster, Harrods.

Enterprise SEO data platform combining crawl, logs, and AI insights.

What people praise

  • JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
  • Log file analyzer processes 500M+ log lines per day, surfacing how Googlebot, Bingbot, and AI crawlers actually behave on the site.
  • Cross-references crawl data, server logs, GSC, GA4, Adobe Analytics, and Majestic backlinks in one analysis - few competitors integrate all five sources.
  • 100% unsampled data analysis appeals to enterprise SEOs frustrated with GA4 sampling and Search Console limits.

Where it falls short

  • No public pricing - book-a-demo gating means SMBs and indie consultants are filtered out before evaluation.
  • Capterra rating of 3.8 is the lowest among major technical SEO crawlers, with reviewers citing UI complexity and pricing opacity.
  • Steep learning curve - the platform assumes data-science fluency, which leaves marketers needing a technical SEO specialist to extract value.
  • Self-serve onboarding is limited; complex multi-source setups (logs plus crawl plus analytics) typically need OnCrawl's customer success team.

The case for Writesonic

Writesonic has raised $2.72M raised (Seed (September 2021, $2.6M)). Founded by Samanyou Garg, based in Bengaluru, India. On their site they list 10 named customers including Amazon, Unilever, Acer, OECD. Pricing starts at $0/mo.

AI content platform with SEO, GEO, and agent workflows.

What people praise

  • Generates a 3,000-word draft in roughly five minutes, useful for fast first-pass blog and ad copy production.
  • Library of 100+ ready templates covers ads, emails, landing pages and social posts so non-writers can start without prompt engineering.
  • Built-in SEO keyword tools and content optimizer reduce the need to bounce between Surfer or Semrush during drafting.
  • Chatsonic gives ChatGPT-style conversational access with real-time web data on every paid tier, useful for research and quick brainstorms.

Where it falls short

  • Long-form blog output frequently reads generic or 'obviously AI' and requires heavy human editing before publish.
  • Multiple Reddit threads describe difficulty cancelling subscriptions and continued charges after cancellation requests.
  • Credit and word limits deplete faster than users expect, forcing mid-month upgrades on the Lite tier.
  • Hallucinations and factual drift on niche topics remain frequent enough that Factual Mode is positioned as a fix rather than a guarantee.

Feature parity

What each one ships that the other doesn't. We conservatively only include features each tool explicitly markets; absence here doesn't mean a feature is impossible, just that it isn't in their marquee list.

Only on OnCrawl
  • SEO Crawler. JavaScript-capable cloud crawler that audits 300M+ URLs, mapping site architecture, internal linking, and orphan pages.
  • Log File Analyzer. Processes 500M+ log lines daily to show how Googlebot, Bingbot, and AI bots interact with the site.

When each one wins

When OnCrawl wins
  • JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
When Writesonic wins
  • Budget is the constraint. Writesonic starts at $0/mo vs OnCrawl's $∞/mo, so on a per-seat basis it's the cheaper way in.
  • Procurement requires SOC 2 Type 2. Writesonic has it; OnCrawl doesn't yet.
  • Generates a 3,000-word draft in roughly five minutes, useful for fast first-pass blog and ad copy production.
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 OnCrawl 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 OnCrawl over Writesonic

  1. More mature platform. OnCrawl (founded 2013) has had more time to harden the product than Writesonic (2020).
  2. What users praise most. JavaScript-capable crawler scales to 300M+ URLs per project, putting it in the same league as Botify and DeepCrawl for enterprise sites.
  3. EU data residency. OnCrawl is HQ'd in Bordeaux, France, which simplifies GDPR data-processor agreements for European buyers.

Reasons to pick Writesonic over OnCrawl

  1. Lower entry price. Writesonic publishes a clear entry tier at $0/mo; OnCrawl gates pricing.
  2. Public pricing. Writesonic publishes 4 tiers on its website; OnCrawl requires a sales conversation.
  3. SOC 2 Type 2. Writesonic carries SOC 2 Type 2; OnCrawl does not yet, which can hold up procurement.
  4. HIPAA-ready. Writesonic is HIPAA compliant; OnCrawl is not.
  5. Higher G2 rating. Writesonic averages 4.7/5 on G2 across 2,065 reviews; OnCrawl averages 4.4.
  6. Built for the LLM era. Writesonic was founded in 2020, built around AI search from day one; OnCrawl dates back to 2013 and is retrofitting.
  7. What users praise most. Generates a 3,000-word draft in roughly five minutes, useful for fast first-pass blog and ad copy production.

Switching from one to the other

From OnCrawl to Writesonic

Export your saved queries and prompt panels from OnCrawl (most tools support CSV export). Most Writesonic setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Writesonic's data againstOnCrawl's; one to two weeks of full reconciliation before you cancel OnCrawl. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.

From Writesonic to OnCrawl

Same flow in reverse. Export from Writesonic, import to OnCrawl. 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.

  • BrightEdge ownership raises long-term roadmap questions for customers who prefer best-of-breed technical SEO over consolidated suites.

Writesonicwhat users praise

  • Multiple Reddit threads describe difficulty cancelling subscriptions and continued charges after cancellation requests.
  • Credit and word limits deplete faster than users expect, forcing mid-month upgrades on the Lite tier.
  • Hallucinations and factual drift on niche topics remain frequent enough that Factual Mode is positioned as a fix rather than a guarantee.
  • GEO module is layered on top of a content tool, so AI visibility analytics feel less detailed than purpose-built platforms like Profound or Otterly.

A third option

Both OnCrawl and Writesonicare 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, OnCrawl or Writesonic?

Honestly: neither one fully solves the problem. OnCrawl and Writesonic 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 OnCrawl 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 OnCrawl and Writesonic cost?

OnCrawl starts at Custom. Writesonic 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 OnCrawl and Writesonic actually improve your AI visibility, or just measure it?

Both OnCrawl and Writesonic 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 OnCrawl and Writesonic?

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.
