#3 avg. position

+16 ahead of QuantumByte

Lovable leads the early-startup AI app builder question, appearing in every single answer across all three assistants while no rival comes close to matching that universal reach.

Lovable is the only brand to hit 100% answer coverage and earns a score 16 points clear of the next-ranked QuantumByte, which itself never appears in ChatGPT's answers at all. Bolt shows up in 83% of answers but lands at an average position 5, limiting its weight despite broad recognition. The reasoning the assistants consistently surface is speed-to-prototype and ease of use for non-technical founders, the attributes that matter most at the earliest startup stage.

Slot score is position-weighted, 0 to 100: being recommended first counts far more than a trailing mention. "Appears in" is the share of answers naming the brand at all.

How this was measured

ChatGPT, Perplexity, and Gemini each answered this question in two phrasings, several times each, with live web access and citations: the closest API-reachable version of the real assistant experience (no personalization or account memory, which no vendor can provide). Model-memory answers (no web) are measured separately and shown above as a comparison surface. A brand counts once per answer that recommends it. The exact questions:

• "What's the best AI app builder for an early-stage startup?"
• "We're an early-stage startup, six people, moving fast on a tight budget. Which AI app builder should we use?"
