The leaderboard — Feature flag platforms by share-of-model

Which feature flag and experimentation platforms do AI engines recommend when teams ask what to use to roll out, target and test features safely? We ran 10 buyer prompts × 10 runs across 5 engines (Perplexity, Google Gemini, ChatGPT (OpenAI), Claude (Anthropic), Grok (xAI)) — 500 total AI answers. Last updated June 20, 2026.

LaunchDarkly leads our AI Visibility Index for Feature flag platforms at 20% share-of-model across 5 AI engines.

Share of model = % of all recommendations (across every prompt and engine) that named the product. Per-engine columns show how often each engine recommends the product. CI = Wilson 95% confidence interval on share-of-model.

Methodology — reproducible, not vibes

A single AI screenshot is one sample from a distribution. This Index treats AI visibility as the statistical question it is: every buyer prompt is run 10+ times per engine, and we report the median rate with a 95% confidence interval.

Buyer "money prompts"

10 real buyer questions a person would ask an AI when choosing feature flag platforms (e.g. "best feature flag platforms for a Series A startup"). Each prompt is run 10+ times per engine.

5 engines, measured separately

We query Perplexity, Google Gemini, ChatGPT (OpenAI), Claude (Anthropic), Grok (xAI) independently, because the engines disagree — being strong in one says nothing about the others. Per-engine columns expose that spread.

Share-of-model + Wilson CI

For each product we report its share of all recommendations in the field, with a 95% Wilson confidence interval — the honest way to summarize a small, noisy sample.

Heuristic detection, disclosed

A product is "recommended" when its name or a known alias is named in the answer (boundary-aware); a citation is counted when its own domain appears in the answer's sources. A mention is not always a positive endorsement — we say so.

API answers approximate, but do not exactly replicate, the consumer apps (different system prompts, tools, browsing defaults). We treat each edition as a point-in-time measurement and re-run on a cadence.

FAQ

Which feature flag platforms do AI engines recommend most?

This feature flag platforms page is an illustrative methodology preview, not a live measurement. In this mock-data sample LaunchDarkly shows the highest share-of-model (19.8%) to demonstrate the format — the first public edition will be a real multi-engine run. See the table above for the layout.

What is share-of-model?

Share-of-model = the percentage of all product recommendations, across every buyer prompt and engine, that name a given product. It answers: when an AI recommends something in this category, how often is it this product?

How is the AI Visibility Index measured?

Each buyer prompt is run at least 10 times per engine across Perplexity, Google Gemini, ChatGPT (OpenAI), Claude (Anthropic), Grok (xAI); we detect which products each answer recommends, compute share-of-model, and report a Wilson 95% confidence interval. The method is reproducible — the same one Clear Cited uses in its paid audits. Note: this category page is currently an illustrative preview generated in mock mode, so the numbers shown are placeholders that demonstrate the method, not measured results.

Why do different AI engines recommend different products?

AI answer engines draw on different training data, retrieval sources, and ranking — so the 'best tool' a buyer hears depends heavily on which assistant they ask. That is why the Index measures and reports each engine separately.

Is this ranking sponsored or pay-to-play?

No. The AI Visibility Index is free, independent original research. Products are not charged to appear and cannot pay to rank higher. It reflects what AI engines actually say, measured transparently.

Want your product's real share-of-model?

We measure where ChatGPT, Perplexity, Gemini, Claude & Grok send buyers in your category — reproducibly — and map the fastest way in.
