AI App Builders: AI Visibility Ranking

AI-native platforms that turn plain-language prompts into working apps. Right now, Lovable is the brand AI assistants recommend most, with a Visibility Score of 64 and the #1 spot in 17% of answers. Head-to-head: Lovable vs Replit →

These rankings are measured from what the three models know from training, not a live web search. When the models DO search the web, see which sources they cite. Methodology.

Three AI models, three different winners in App Builders.

ChatGPT leans toward Replit at 56.3 while Claude breaks hard for Bolt at 68.3, and Gemini sides with Replit at 60.4, leaving no consensus leader across the three models. Lovable wins the overall index score at 63.5 and the broadest mention rate at 79%, but that aggregate masks genuine model-level disagreement rather than reflecting a clear default choice. Cursor is the sharpest outlier: it earns the highest first-pick rate at 25% yet sits fourth overall, meaning when a model does choose it first, competitors rarely agree.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.

Just below the cutoff: Windsurf (6), Retool (5.7), Microsoft Azure AI Studio (5.6), Microsoft Azure AI (4.2), Adalo (4). 87 brands were scored in this category; the leaderboard shows the top 15.

Visibility Score: position-weighted presence across all measured answers, 0 to 100. A score of 100 means the brand was the first recommendation in every answer. Every point in a trend line is a live monthly measurement; there is no modeled or backfilled history. Full methodology.

Openness 37/100: the share of this category's recommendation weight not held by the leader.

Who wins for what

AI buying questions are long tail: real buyers ask for their size, industry, budget, and situation, not just "what's the best ai app builders". Each column is one of those qualified questions, scored the same way as the main ranking but measured on the lived surface: real assistant answers with live web access. The slot score is position-weighted: being recommended first counts far more than a trailing mention.

The first column is the overall (unsegmented) pick; the rest are segmented questions — a full row is breadth, a single dot is a niche a brand owns. Overall = the headline model ranking; segment dots = the live, web-grounded surface.
