Abstract: We define a general class of superconformal inflationary attractor models [R. Kallosh et al., Phys. Rev. Lett. 112, 011303 (2014); J. High Energy Phys. 11 (2013) 198; A. Linde, arXiv:1402.0526, R. Kallosh, arXiv:1402.0527], which include, among others, inflationary models of ``induced gravity'' which were argued to retain perturbative unitarity up to the Planck scale [G. F. Giudice and H. M. Lee, arXiv:1402.2129]. The choice of the function $f(\ensuremath{\phi})$ in superconformal attractors for the models introduced by Giudice and Lee [arXiv:1402.2129] is $f(\ensuremath{\phi})={\ensuremath{\phi}}^{n}\ensuremath{-}{\ensuremath{\xi}}^{\ensuremath{-}1}$. We present both superconformal and supergravity versions of these models, which were derived by Kallosh et al. [Phys. Rev. Lett. 112, 011303 (2014); J. High Energy Phys. 11 (2013) 198]; Linde [arXiv:1402.0526], Kallosh [arXiv:1402.0527] for arbitrary $f(\ensuremath{\phi})$, together with the universal conditions required for stabilization of the extra three moduli present in the superconformal attractors, in addition to the inflaton.
