# AI Assistant vs Build Foundation

The clearest difference is review sentiment: Build Foundation at 100% against AI Assistant's 50%. Build Foundation also leads on ads (none vs shown) and rating (5.0 vs 4.6). AI Assistant's advantage is ratings volume (70 vs 2). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. AI Assistant sells 2 in-app purchases, starting at $6.99 per 7 days and Build Foundation sells 3 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

Build Foundation holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: AI Assistant has 70 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of AI Assistant's written reviews are positive against 100% of Build Foundation's.

AI Assistant ships an update every 11 days, Build Foundation every 2 weeks. The most recent releases landed on October 15, 2026 and October 17, 2026 respectively.
