Reddit, Hacker News, YouTube, Stack Overflow, GitHub, Lemmy
What users praise
- • Open-source Synthetic Data SDK under Apache v2 lowers barrier to try.
- • Multi-table synthesis with referential integrity suits complex relational data.
- • Differential privacy with temperature control gives granular privacy tuning.
- • Agentic data science layer automates training and sampling workflows.
What frustrates them
- • Near-complete absence of real user feedback after years of availability.
- • No evidence of community trust or third-party validation in reports.
- • Pricing is hidden behind contact sales – a barrier for small teams.
- • Name ambiguity with 'mostly AI' phrase makes it hard to find discussions.

Feature-by-feature
Mostly AI is a synthetic data platform featuring agentic data science, natural-language AI assistant, multi-table synthesis with referential integrity, time-series support, and differential privacy. It integrates with major data warehouses (Databricks, Snowflake, BigQuery) and can be deployed on Kubernetes or OpenShift. The open-source SDK (Apache v2) allows local generation. In contrast, Attention Insight is a design analytics tool that generates AI attention heatmaps (96% accuracy), Clarity and Focus Scores, contrast maps, and AI recommendations. It offers side-by-side comparisons, shareable reports, and video attention testing (1s per credit on Pro, 30 min on Hero). Integrations include Figma, Chrome, Adobe plugins, and API. Notably, Attention Insight's latest interviews (2026) emphasize UX and conversion-focused design, while Mostly AI's recent news highlights LLM + Python for smart datasets.
Pricing compared
Mostly AI requires contacting sales for pricing, with no publicly available tiers. It targets enterprises and data teams that can afford custom licensing. Attention Insight operates on a freemium model: a free tier exists, with paid Pro/Hero plans that introduce credit-based usage (e.g., video testing limits). For users needing quick design validation, the free tier may suffice, but high-volume usage will incur costs. Given Mostly AI's opaque pricing, budget-conscious buyers may find Attention Insight more accessible, but the tools serve different needs.
