# Lucidchart vs ChatGPT

The clearest difference is review sentiment: ChatGPT at 70% against Lucidchart's 21%. ChatGPT also leads on update cadence (weekly vs every 2 months) and ratings volume (11M vs 5.3K). Lucidchart's advantage is iOS requirement (16.0 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Lucidchart sells 2 one-off in-app purchases and ChatGPT sells 8 in-app purchases, starting at $8.00 per month. Whichever you choose, the download price is not the number that matters.

ChatGPT holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: ChatGPT has 11M ratings behind it against 5.3K, so its average is the more settled of the two. Written reviews point the same way: 21% of Lucidchart's written reviews are positive against 70% of ChatGPT's.

Lucidchart ships an update every 2 months, ChatGPT weekly. The most recent releases landed on August 31, 2026 and September 24, 2026 respectively.
