Feb 14, 2024Introducing Multiplayer AI Chat
One of our core beliefs at Replit is that multiplayer collaboration makes building software more creative and efficient. After introducing Replit AI for All last year, we heard from our users how transformative AI has been to their development workflows. Today, we are announcing several updates to our AI Chat product, but most importantly, we are bringing the multiplayer power of Replit to AI. We will continue to offer AI to all users, with advanced models available for Replit Core members, but now with the ability to collaborate with others in multiple, persistent chat sessions. What's new? Multi-session chat with persistence You can now create and manage multiple chat sessions when interacting with Replit AI. Creating multiple threads with our AI products allows you to switch between asking for explanations about files in your codebase, generating code for a new feature, and debugging, all without losing your progress. This was a top feature request, and we’re excited to bring multi-session functionality to the platform so developers can stay organized and engaged, all within the same familiar workspace UI.

Dec 26, 2023Introducing Spellburst, A Replit x Stanford HAI Collaboration
At Replit, we’re lucky to work with brilliant people who are building the programming tools of the future. This past year, we had the privilege of sharing some of this design work with the broader academic research community. Tyler, design engineer at Replit, teamed up with Stanford University (Jenny Han – also former Replit intern), Miroslav Suzara, Christopher Pondoc, and Dr. Hari Subramonyam) to publish Replit’s first-ever peer-reviewed publication, Spellburst. In November, we presented our work at the ACM Symposium on User Interface Software and Technology (UIST), one of the premier venues for human-computer interaction research in the world. This post will walk through what we built and researched, what we learned from the process, and some predictions for user interface design and AI in the future. Introducing Spellburst We went into this project knowing that we wanted to design for learning and creativity for coders. In our formative study, we interviewed 10 expert generative artists to understand their existing workflows. What we discovered about the exploratory process for creative work is that creative coders are constantly: Going from idea to code
Dec 22, 2023Builder Profile: Ismail Pelaseyed
Ismail Pelaseyed is the CTO and co-founder of Superagent, an open-source framework that enables developers to build, manage, and deploy AI Assistants. Ismail is an experienced developer who is dedicated to building open source software. After many years of running a successful consulting firm with his business partner, Alan Zabihi, they wanted to go back to building projects for themselves, focusing primarily on open source AI and agent frameworks. Eight years ago, Ismail and Alan built KeyCrunch (now Hyperdrive), which automatically writes marketing copy for users. They continued to expand the function of KeyCrunch into a tool that generates ad materials with the help of AI agents. Their goal was to get mainstream developers without expertise in ML to integrate AI into their applications. The company was eventually acquired by Jetshop, but Ismail and Alan continued to focus on agents and accessible AI dev frameworks in their next project: Superagent.
Dec 21, 2023Company Spotlight: CrewAI
AI agents are here to stay Large Language Models (LLMs) are everywhere, doing various jobs, from chatting to parsing documents. Soon after LLMs took the world by storm, developers started creating more focused, goal-oriented LLM apps modeled after human reasoning and problem-solving, which became known as AI agents. Here’s how one company is leveraging LangChain and Replit to solve complex tasks. AI agents with CrewAI CrewAI is a library specifically designed to build and orchestrate groups of AI agents. It's made to be straightforward and modular, so integrating it into your projects is a breeze. Think of CrewAI like a set of building blocks - each piece is unique, but they're all designed to fit together smoothly. Built on top of LangChain, it's inherently compatible with many existing tools, including local open-source models through platforms like Ollama. The AI agents can run natively on the cloud with Replit, making it even easier to get started with CrewAI. Check out the CrewAI templates on Replit to see the agents in action. Or, use them as a starting point for your own projects so you don't have to start from scratch. Here’s how it works.

Dec 15, 2023Updates to Social Features on Replit
In 2024, we're excited to introduce improvements to our social features on Replit, all centered around making it easier to share and explore code. We learned from our top creators that a cover page's primary value is sharing code and giving other developers something to fork. Additionally, we recognized that viewing applications in an iframe is a suboptimal experience. Often, missing Secrets prevented the program from running as intended. The best way to view someone’s work is to visit the production deployment directly. With this in mind, we’re reimagining cover pages to focus primarily on code consumption. This shift marks a move away from running and viewing program outputs. Instead, we’re making these pages a hub for exploring and understanding code. Starting early next year, when you land on a cover page, it will show the project’s code or README file. They’ll be presented in an intuitive, editor-like environment for more straightforward navigation. When you find a project you want to work with, forking it is straightforward. We’ll set up an identical development environment for you so you can start making changes or running the code immediately.
