10 Best AI Assistants 2026

The 10 best AI Assistants in 2025 are ChatGPT, Gemini, fonio AI Phone Assistant, Claude, Microsoft Copilot, Perplexity, Breeze Copilot, Adobe AI Assistant, Canva AI Assistant, and Notion AI. AI Assistants are virtual assistants that increase productivity and reduce workload.

AI-supported assistants take on time-consuming, repetitive tasks that are assigned to them and would normally be performed by a human. Examples of tasks that personal AI Assistants take on include answering customer questions, managing email inboxes, writing texts, coordinating meetings, and providing information.

Intelligent assistants are based on various language models, such as natural language processing (NLP) and use a large language model (LLM) to process natural human language and text. AI Assistants understand both text input and voice commands and are used to save time as well as simplify processes. Using AI Assistants frees up more time for other tasks.
