Pick
Relixir
Pick Relixir if you want the cheaper option ($500/mo vs $99/mo); and you need broader AI platform coverage (4 platforms vs 0).
Head-to-head review · Updated June 2026
Relixir vs Topic: which one wins in 2026?
Relixir and Topic 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. Relixir is the more-funded incumbent; Topic is the leaner challenger.
Topic is cheaper out the gate, but Relixir tracks more AI platforms. The right pick depends on which dimension matters most for you.
The verdict
Pick
Topic
Pick Topic if you want the cheaper option ($99/mo vs $500/mo); and you trust traction signals — they list 9 customers, Relixir lists 4.
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 Relixir
Relixir has raised $2M seed (Seed (November 2025)). Founded by Sean Dorje, Dennis Zax, based in San Francisco, CA. On their site they list 4 named customers including Rippling, Airwallex, HackerRank, Retell AI. They cover 4 AI platforms. Pricing starts at $500/mo.
YC-backed GEO platform that auto-produces optimized content to rank brands higher in ChatGPT, Perplexity, and other AI search engines.
What people praise
- Monitors brand visibility across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews in a single dashboard, not just one platform.
- Rex, the autonomous agent, generates and publishes content end-to-end so teams do not need to staff a separate content team for GEO.
- Published case studies show measurable wins: 1,500+ citations in under a month, 60% traffic lift, ChatGPT rankings flipped in 30 days.
- Visitor identification reveals which companies are arriving from AI search, which marketers cite as a differentiator versus pure monitoring tools like Profound.
Where it falls short
- Entry pricing starts at $500+/mo, which reviewers flag as too high for SMBs and agencies running tight content budgets.
- Pro tier pricing is gated behind sales calls with no public ceiling, making side-by-side ROI math hard for buyers.
- Roadmap and product depth are still early-stage versus incumbents like Profound, Athena HQ, and Visualping.
- No public G2 or Capterra review presence yet, so social proof relies on first-party Relixir blog case studies.
The case for Topic
Founded by Ryo Chiba, Nikhil Aitharaju, based in Toronto, Canada. On their site they list 9 named customers including Magoosh, Quizlet, BiggerPockets, Amerisleep. Pricing starts at $99/mo.
Content optimization platform that turns research into briefs and outlines.
What people praise
- Cuts content research time 45-50% by auto-parsing the top 30 Google results for headings, questions, and keyword targets.
- Simple Starter at $99/mo and $7 intro pack make it the cheapest serious entry point versus Surfer, Clearscope, and MarketMuse.
- Magoosh case study shows 300%+ year-over-year new-user growth on a single optimized post.
- Used by BiggerPockets, Magoosh, Quizlet, Amerisleep, Elementor, TrustRadius, and WSI.
Where it falls short
- Brief and optimization quotas (10 to 50 per month) are tight for agencies running multiple clients.
- No native AI article generator at the level of Surfer AI or Frase Pro; Topic positions as briefs, not full drafts.
- Pricing changes infrequent and no free trial beyond the $7 intro pack.
- Acquired by CafeMedia/Raptive in September 2021; roadmap pace has slowed compared to standalone Surfer or Clearscope.

When each one wins
When Relixir wins
- Platform coverage matters. Relixir monitors 4 AI platforms; Topic covers 0.
- Monitors brand visibility across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews in a single dashboard, not just one platform.
When Topic wins
- Budget is the constraint. Topic starts at $99/mo vs Relixir's $500/mo, so on a per-seat basis it's the cheaper way in.
- You're enterprise and need to call a reference. Topic lists 9 named customers; Relixir lists 4.
- Cuts content research time 45-50% by auto-parsing the top 30 Google results for headings, questions, and keyword targets.
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 Relixir 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 Relixir over Topic

- Wider integration ecosystem. Relixir integrates with 8 tools; Topic ships 3.
- What users praise most. Monitors brand visibility across ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews in a single dashboard, not just one platform.
Reasons to pick Topic over Relixir

- More plan flexibility. Topic offers 4 pricing tiers vs Relixir's 3, so there's a better chance one fits your team size.

Switching from one to the other
From Relixir to Topic
Export your saved queries and prompt panels from Relixir (most tools support CSV export). Most Topic setups can import the same query list in a single CSV upload. Expect 1-2 days of parallel running so you can validate Topic's data againstRelixir's; one to two weeks of full reconciliation before you cancel Relixir. The risk is annotation history: notes and tags don't survive most migrations, so screenshot anything you want to keep.
From Topic to Relixir
Same flow in reverse. Export from Topic, import to Relixir. 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 Relixir and Topicare 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, Relixir or Topic?
Honestly: neither one fully solves the problem. Relixir and Topic 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 Topic 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 Relixir and Topic cost?
Relixir starts at $500/mo. Topic starts at $99/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.
Which AI platforms do Relixir and Topic cover?
Relixir covers 4 AI platforms. Topic covers an undisclosed number of. Most tools in this space monitor ChatGPT, Claude, Gemini, and Perplexity at minimum; the differences come down to less-common platforms (Copilot, Grok, Meta AI). GrowthManager.ai monitors the same four primary platforms and acts on the data.
Do Relixir and Topic actually improve your AI visibility, or just measure it?
Both Relixir and Topic 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 Relixir and Topic?
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.
