An apparatus for preparing a personal smokable product includes: a grinder section comprising a grinder for grinding plant material; a holder section attachable to the grinder section and comprising a holder receiving a wrapper support for supporting a wrapper for receiving ground plant material when aligned with the grinder; and one or more removably attachable auxiliary modules, which may include a dry herb vaporizer, an oil vaporizer, an audio speaker, and/or a storage compartment. The grinder includes a cutter having wall blades projecting from a chamber-defining wall toward a central axis of the chamber; a motor-driven shaft rotatable about the central axis, and shaft blades projecting radially from the shaft. The grinder includes conical bun members with an adjustable gap for coarseness. Even when the grinder section and the holder section are attached to each other, the wrapper is user-accessible if the holder is in its non-aligned position.
