Artificial intelligence is almost like a new universe coexisting with us in our world. With a vast amount of tools and platforms available for direct use, we are now also building custom AI tools to suit our requirements. When learning about the best AI tools and the frameworks behind custom tools, we realize that we have only scratched the surface of AI technology yet. In this blog, we shall discover the best AI tools you can try for free and the best AI frameworks used in AI development companies. Beginners can use this blog as a guide to free AI tools, while those interested in AI software can indulge in the AI framework details.
The Best AI Tools and Frameworks
Custom AI tools would take a good long time to build from scratch. That would require coding AI or machine learning models. Instead, developers use AI frameworks or tools that simplify the process of building, training, and deploying AI or machine learning models. These frameworks are ready platforms for apps, so there is no need to build from scratch. Just plug into these ready frameworks and get the desired results.
The AI toolkits or frameworks are not all the same. Each one differs from the others in its focus or functioning. Some focus on language models like ChatGPT, while others focus on AI-powered web apps, or some connect multiple AI tools. Here, we shall go through a list of developers’ favourite AI frameworks.
-
LangChain
The shift of chatbot conversations that felt like a waste back in time to the modern-day, humanized chatbots is because of Langchain. LangChain is the AI framework that helps developers build conversational AI by connecting large language models with external data sources, memory, and logic. These AI assistants built with Langchain will not respond to queries with pre-defined answers; rather, they will make the bot fetch data from real-time sources from the company database to give accurate answers.
-
LlamaIndex
LlamaIndex was formerly known as the GPT index. It organizes and retrieves information for AI can process that information better. After all, AI is dependent on its data for the right performance. For instance, you have a hundred PDF reports. Upon asking a normal AI about them, it would not give you answers. However, with LlamaIndex, you can feed your PDFs into AI model, and it will answer your questions based on the reports. Some of the popular AI tools and platforms integrate LlamaIndex to enhance their data processing.
-
Haystack
Haystack is again an AI solution that quickly finds answers from large documents. This framework allows an advanced search and question-answer system. So, if you integrate it into a website about fashion tips, a user can come and search for summer fashion tips, and AI will guide them to the articles with the answer to their query. Haystack suits the project that requires an AI-powered search. It can easily manage legal documents or scientific papers. So hours of manual search can be reduced to seconds of scanning with AI tools that use Haystack in their framework.
-
Pydantic AI
As artificial intelligence tools rely on data for their performance, the quality of data available must be ensured before use. Pydantic AI validates and cleans data for AI applications to operate smoothly. It can be used for building AI tools that analyze customer reviews to understand product feedback. Because customer reviews usually come in broken sentences, words, or even phrases.
-
Streamlit
If you want AI systems in web apps, Streamlit is the best way to go. It allows you to create interactive AI tools with minimal Python code, which can be done without a developer. A certain AI model would be accessible only to the people who know how to run Python scripts, but Streamlit can turn it into a simple web app for everyone.
-
Gradio
Gradio is another framework, like Streamlit, that makes AI models accessible to everyone through an easy interface. It is almost like a game where users can interact with AI without any code. It is more popular for creating AI models that generate text-based images. Gradio also works with speech-to-text and text-to-speech tools, AI chatbots, language models, AI art tools, and Medical AI apps etc.
-
Chainlit
Chainlit is capable of linking or chaining multiple AI models together to build powerful applications. It works best for complex AI workflows with multiple steps, where different AI systems work together to achieve a goal or finish a task. Many businesses and AI-powered platforms use Chainlit to manage their workflows.
-
CopilotKit
CopilotKit is such a tool that it can add AI assistance to any application and make it interactive, personalized, and collaborative. It is the best tool for spreadsheet users as AI can suggest correct formulas based on your typing, detect errors and correct them, automate repetitive tasks, etc. Basically, CopilotKit integrates artificial intelligence into your workflow. Some of the best examples of it include writing and editing apps, where AI corrects and enhances your writing, and CRM and customer support software.
List of The Best AI Tools
If you wish to try multiple AI tools before you choose your preferences, here are some of the best AI tools. These tools are either free or have a free plan, so you can easily try them for yourself. Let us have a look at the best AI assistants.
-
ChatGPT
Everyone knows this one; it has been used by everyone for personal or professional tasks. Its best feature is the ability to upload and analyze files. You can use PDFs, spreadsheets, screenshots, texts, and ChatGPT can summarize, refine, or analyze that data. It provides trends information, key insights, recommendations, and even graphical or chart form visualization from raw data.
-
Grok
Grok is an AI assistant, but also an integral part of X ( formerly known as Twitter). Groke is a super smart AI model, and it is quite uncensored. It has several reasoning modes like “Think” and “Deep Search,” which allow it to take up more time refining its response or searching the internet deeply, respectively. It also has an impressive image generation capability. It can be accessed for free, but with limited usage.
-
Cluade
Claude is a go-to AI assistant for coding. Even though a lot of other tools have come up with similar functions, developers still believe in Claude the most. It is good at writing clean code, and also great at explaining what that code does in English. Its code is reliable as well. Claude is your collaborative assistant who communicates well. It is available for free but has pro and max plans for higher limits.
-
Gemini
Gemini is Google’s AI assistant, which is also among the list of 9 top large language models. One of the best things about Gemini is the amount of text it remembers during a conversation. The latest Gemini models support about 1 million tokens of context, meaning you can drip a long academic paper and ask questions from it, and it will answer them all properly. Another good thing about Gemini is its audio overview. So, it can summarize or create a podcast-style audio file of texts and documents so you can listen to them on the go instead of reading. Gemini has a free plan with basic AI tools, while there are other Pro and Ultra plans that allow access to advanced models and more features with storage.
Let us have a look at the top AI automation models, which one might like to use for business purposes. Here are the best AI tools for automation.
-
N8n
If you want to automate a boring, repetitive task, n8n lets you do it. It feels a little complex at first, but with time, it becomes easy to use. To create an automation in n8n, you need to connect apps and services in a visual workflow. You can then simply drag and link nodes together. For this, you don’t need to know coding. However, if you know how to code, n8n also gives the flexibility to customize functions even further.
-
Manus
Manus is an AI agent that can perform a wide range of tasks. From creating slides to data analysis and even image generation. It can build web pages and handle programming tasks as well. It does so by combining different LLMs and other models to complete the requested tasks. Manus has more reliability and better output quality. It has a free plan with 300 daily credits and basic features. Its paid plans unlock more credits, advanced models, and media generation.
Conclusion
Even if we think we have gained a lot of new information, we still have a long way to explore the AI universe thoroughly. Apart from the AI assistants and automation models, several other AI tools perform different tasks. Learning more about the core technologies like LLM, Neural networks, Machine learning solutions, and data analysis helps us understand different AI models easily.
