Question: I'm looking for a platform that allows users to share their experiences and knowledge about cars, and creates a collective knowledge base.

If you're looking for a platform to let people share their experiences and expertise about cars, building a collective knowledge base, Rewise is a strong contender. Rewise indexes and interlinks millions of car owner questions, answers and comments with Natural Language Processing (NLP) technology. The service has more than 4 million users per month and has a deep semantic knowledge graph covering all aspects of vehicles. The service fills in gaps in data by turning small-scale discussions into large-scale knowledge, and it lets people quickly find what they're looking for.

Another strong contender is Document360, an AI-powered knowledge base tool for building, managing and publishing knowledge bases. It's got a lot of features, including a knowledge base portal, category manager and analytics. Document360 is good for technical writers, product owners, customer support teams and developers who want to expand customer support without expanding support costs. The service integrates with more than 120 tools and has powerful search and AI-powered suggestions, so it's a good tool for managing and sharing knowledge.

If you want a service that combines file storage with AI-powered chat, check out Knowbase. The service lets you store and retrieve files, including video and audio recordings, by asking conversational questions. It can handle many file formats and transcribe video and audio recordings in many languages. Knowbase is good for keeping information organized so it's easier to find, remember and share, a useful ability for carmakers and others in the automotive industry who need to manage huge knowledge bases.
