This paper studies undergraduate students' perceptions about using Google Docs® for guided writing of the final assessment in an Academic Writing course at a Higher Education level. Qualitative data have been collected through a Moodle survey and analysed employing Thematic Analysis. The aim is to see if students' perceptions matched with their teacher's aims, which were to reduce assessment anxiety toward a new and complex writing assignment such as a Literature Review; help working more effectively and reduce procrastination; and possibly enhance success rate. Results show that overall, students liked the technical features (autosaving, accessibility), the guidelines and examples contained in the template shared, and the role of the teacher as controller and provider of feedback and feedforward. Yet some few divergences between the teacher's aim and students' perceptions emerged: some students did not like working on-line, expressed preference for Microsoft Word®, found the procedure time-consuming or constraining, or even too easy. Most importantly, some students felt stressed about being watched. Therefore, if teachers want to adopt the same procedure, they should make sure they explain as clearly as possible the aims of the use of technology to maximize effectiveness and minimize students' resistance.
