(7)+ Platforms to Build AI Agents in 2025: A Complete Guide

Artificial Intelligence (AI) is no longer just about chatbots and smart recommendations. Today, AI agents are reshaping the way we work—automating tasks, reasoning through decisions, and collaborating like digital teammates. If you’re looking to create AI-powered agents for business or personal productivity, a growing number of platforms make it possible without heavy coding knowledge.

In this blog, we’ll explore some of the leading tools—Relevance AI, Stack AI, n8n, Taskade, Flowise, MindStudio, VectorShift, and Make.com—and what kind of work you can do with each.

1. Relevance AI – Build an Entire AI Workforce

Relevance AI helps businesses create multi-agent systems that work like a digital workforce. You can visually design AI agents, assign them tasks (customer support, outreach, SEO, or research), and even have them collaborate.

• Build reasoning bots that plan and act autonomously

• Automate sales outreach and marketing campaigns

• Handle customer queries with AI-powered support agents

• Integrate multiple LLMs like OpenAI, Anthropic, or Google Gemini

This makes Relevance AI perfect for teams that want to scale repetitive or complex workflows.

2. Stack AI – Enterprise-Grade AI Automation

Stack AI focuses on enterprise automation. It allows you to create AI agents that handle back-office work such as data entry, categorization, content aggregation, or information retrieval.

• Drag-and-drop workflow builder for non-technical teams

• Integrates with business tools like Salesforce and Snowflake

• Useful for automating repetitive knowledge and data tasks

Companies that deal with large amounts of structured or unstructured data can save hours by deploying Stack AI agents.

3. n8n – Workflow Automation with AI Superpowers

n8n started as a workflow automation tool, similar to Zapier, but with much more flexibility. Now, it has added AI capabilities, letting you build AI-powered workflows that integrate with hundreds of apps.

• Connect data from multiple sources into LLMs

• Automate multi-step processes with AI decision-making

• Use pre-built AI nodes for quick setup

For example, you could automatically collect customer feedback, summarize it with GPT, and send insights to your Slack channel—all hands-free.

4. Taskade – AI Teams for Productivity

Taskade combines project management with AI agents. Imagine having digital teammates who handle brainstorming, drafting, task generation, or even customer support.

• Create autonomous agents for marketing, research, or support

• Built-in AI Assistant for writing, summarizing, and planning

• Over 700+ automations with integrations to tools like Gmail and Slack

For collaborative teams, Taskade is a productivity booster—turning AI into a partner for managing projects and workflows.

5. Flowise – Open-Source Agent Builder

Flowise is an open-source, visual platform for building and deploying AI agents. Developers love it because it offers full flexibility and freedom to experiment.

• Drag-and-drop interface to design LLM-powered agents

• Supports debugging, analytics, and human-in-the-loop workflows

• Use cases: customer support bots, chatbots over documents, sentiment analysis, translation tools

If you want to build highly customized AI systems and prefer open-source solutions, Flowise is one of the best choices.

6. MindStudio – No-Code AI App Builder

MindStudio focuses on making AI app creation simple and fast. It’s a no-code platform where you can assemble LLMs, data sources, and logic into complete applications.

• Build chatbots, knowledge tools, and multi-modal assistants

• Deploy AI apps in minutes without coding

• Integrate with APIs and data for powerful workflows

This platform is great for startups, educators, and businesses that need to spin up intelligent apps quickly.

7. VectorShift – AI for Document and Knowledge Automation

VectorShift helps businesses automate document workflows and knowledge management.

• Build AI chatbots that can search across company knowledge bases

• Generate documents automatically from templates and data

• Integrate with Google Drive, Salesforce, and Notion

• Works with multiple LLM providers (OpenAI, Anthropic, Hugging Face, etc.)

If your organization spends a lot of time creating, storing, and searching documents, VectorShift is an ideal AI partner.

8. Make.com – AI + Automation for 2,000+ Apps

Make.com is known for visual automation (like Zapier), and in 2025, it introduced AI agents. This means your workflows can now “think” instead of just following rules.
