Context

PastaBot is a conversational assistant designed to help users prepare recipes and manage their ingredients day to day. Built as a true kitchen sidekick , PastaBot embodies a strong personality — at once bossy and endearing — guiding users while keeping a humorous, warm tone.

Run as a team with Salomé Lagarde, Jolan Gouret Piat, Thibault Guitard, Brittany Remigereau and Clara Plateau , the project set out to explore the potential of conversational language within a voice assistant built with Voiceflow. The goal: deliver a smooth, natural and entertaining experience, true to the culinary world.

Project goals

- Define the bot's full personality : tone, speech style and behaviours.
- Design a coherent conversational journey with Voiceflow.
- Test user engagement with an assertive bot identity.
- Analyse the emotional reception of the tone used and its impact on the experience.

My approach

With the team, I began by creating the bot persona : a chef with an assertive, funny and slightly grumpy character, speaking a casual, direct language . This identity work anchored PastaBot in a coherent, memorable experience.

Next, I developed several conversational scenarios with the team, centred on fridge management, recipe search and daily reminders. Each dialogue was tested and adjusted for the bot's flow and tone of response.

User feedback highlighted a smooth delivery and a striking personality: « I love the bot's personality » or « The humour works well ». A few critiques also let me optimise dialogue length and soften some responses felt to be too curt.

The outcome

An embodied voice assistant — funny, effective and simple to use. PastaBot shows that a conversational AI with strong personality can make interaction more human, engaging and memorable. The project also explored the creative potential of Voiceflow in designing rich, narrative voice journeys.
