Reviewers mostly see Spline as an accessible, capable 3D tool that makes it easy to create polished assets quickly, especially for beginners, with strong tutorials and a growing asset library. Several users still note a real learning curve, particularly for people without 3D experience, and one review says the tutorial pacing misses both true beginners and advanced users. Criticism is sharpest around billing and support, with complaints about confusing cancellation, renewal handling, slow responses, and one user also calling the AI rendering inconsistent.
