ChatGPT vs Perplexity vs Gemini: Which AI Platform Recommends You Most?

Teehoo Martech Research · March 23, 2026 · 6 min read

We ran the same purchase-intent queries across ChatGPT, Claude, Gemini, and Perplexity for 15 brands across 5 product categories. The results are remarkably different between platforms.

A brand can be #1 on Perplexity and completely invisible on ChatGPT. Here's what we found.

The experiment

For each brand, we asked 3 purchase-intent queries (e.g., "best robot vacuum 2026") across all 4 platforms. We recorded whether the brand was mentioned, its ranking position, and which competitors appeared.

Key finding: each platform has a different winner

Category	ChatGPT #1	Claude #1	Gemini #1	Perplexity #1
Portable Charger	Anker	Anker	Anker	INIU
Robot Vacuum	Roborock	iRobot	Roborock	Dreame
Wireless Earbuds	Sony	Sony	Sony	Jabra
USB-C Hub	Anker	CalDigit	Anker	Anker
Smart Lights	Philips Hue	Philips Hue	Philips Hue	Govee

Only 11% of domains are cited by both ChatGPT and Perplexity. They're essentially different search engines with different results.

Platform profiles

ChatGPT: the establishment pick

60% of queries answered from training data (no live search)
Strongly favors well-known brands (Apple, Sony, Anker)
Hardest platform for new or smaller brands to appear on
Most-cited sources: Wikipedia, Reddit, major publications

Claude: the objective analyst

Uses Brave Search
Favors structured data and multi-source verification
Penalizes pure marketing content (0.8x weight)
Rewards content that acknowledges limitations (1.7x weight)
Most likely to recommend niche/specialized brands

Gemini: the Google native

Uses Google Search
Most aligned with traditional SEO rankings
Good at surfacing brands with strong Google presence

Perplexity: the fresh finder

Best platform for newer brands to gain visibility quickly

Strategic implications

If you're a new brand: Focus on Perplexity first. Create fresh content, post on Reddit, and you can appear within days. ChatGPT will take months.

If you're an established brand: You're probably already visible on ChatGPT and Gemini. Check Claude and Perplexity — you might be missing from their results.

If you're a Chinese brand: Perplexity is your best bet. It uses real-time search and is less biased toward Western brands. ChatGPT is the hardest to crack.

The bottom line

Optimizing for one AI platform doesn't mean you're visible on all of them. Each platform uses different search engines, different source preferences, and different ranking logic. You need to track and optimize for each one separately.

ChatGPT has the largest user base (300M+ weekly active). But Perplexity users have higher purchase intent — they're specifically searching for answers, not chatting.

Perplexity is the only platform that consistently shows clickable citation links. You can track Perplexity traffic in Google Analytics via the referrer "perplexity.ai".

How often do AI recommendations change?

Perplexity changes daily (real-time search). ChatGPT changes slowly (training data updates every few months). We recommend scanning weekly to catch shifts.
