CopilotKit is a typescript library for adding a hackable copilot to any react app. You can let the copilot interact with your app via plain typescript closures, and give it (explicit) read access to app data. An example user interaction could look like: - "Which of these travel destinations has a rich architecture history?" - [Copilot answers] - "Great. Add these to my august trip folder, except the ones where it's typically rainy then" - [Added] Recursive agent integration (via Langchain) is in the works - if you have ideas I'd love to hear them here or on the discord.

`` is a drop-in `` replacement (looks identical & supports all customizations & params) w GPT completions (like in Gmail / GitHub Copilot). It's built with slateJS and works with any OpenAI-compatible endpoint (bring your own backend). You pass it a "purpose" prompt & external context to inform completions. E.g. the demo gif[1] has a purpose of "COOL and SLICK announcement post", and was given the CopilotKit release notes as context. (super important, to make suggestions specific). Part of CopilotKit (open-source copilot/sidekick infra). IMO it works really well. After working with…

Hey HN, I wanted to share a UI toolkit project I’ve been working on recently, born out of how difficult I found it to build a great UX on top of LLMs, and keep application state in sync. I’ve built: - A React/JS front-end library for conversational interfaces, which makes it super easy to bootstrap AI assistants and ChatGPT style UX: https://github.com/nlkitai/nlux - A set of adapters that simplify integration with AI backends such as LangServe and HuggingFace The library is highly configurable, easy to theme, supports markdown streaming (that was tough to get…

Karektar is a React/TS app for building exportable bitmap fonts from custom glyph sets. You can submit your own input string, and the app will generate the gallery of unique glyphs. Build your own designs using the various tools available, then export it to an OTF format when you're done. This is my first front-end project, and one I picked up to learn React. I'd love to hear any feedback, especially on usability and additional features you'd like to see. Cheers!

Hey HN OpenCopilot is an OSS framework which helps devs to build open-source AI Copilots that actually work and embed into their product with ease. Why another LLM framework? Twitter is full of impressive LLM applications but once you peel off the curtains it’s clear that they are just demos. The reason being because building an AI Copilot that goes beyond a Twitter demo can be complex, time-consuming and unreliable. Our team has been in the AI space since 2018 and built numerous LLM apps & copilots. While doing that, we got approached by many startups saying they’d also like to build a…

I'm Varun from the Codeium team. After support for VSCode, Jetbrains, Jupyter, and Colab, we are super excited to bring free AI-powered code autocomplete to Vim and Neovim. And in the spirit of Show HN, we have a playground version for anyone to try the tech in the browser without any installation (https://www.codeium.com/playground)! We also made the vim client open source and are open to contributions.

Hi HN, Code Llama was released, but we noticed a ton of questions in the main thread about how/where to use it — not just from an API or the terminal, but in your own codebase as a drop-in replacement for Copilot Chat. Without this, developers don't get much utility from the model. This concern is also important because benchmarks like HumanEval don't perfectly reflect the quality of responses. There's likely to be a flurry of improvements to coding models in the coming months, and rather than relying on the benchmarks to evaluate them, the community will get better feedback from people…

Everyone's shipping AI tools right now, and here I am with a visual editor. Still, I think many teams are very familiar with the problem of "marketing wants to change the landing page again." I've run into this for years. Campaign pages come in, engineers get pulled in, and tickets stack up. It's usually the same components, just rearranged. A few years ago, at a startup I worked at, we built an internal tool to deal with this. You register your existing React components, they show up as drag-and-drop blocks, and the result is a JSX string. No schema to learn, no changes to your component…

Hey HN! I'm Andrew, one of the creators of Glass, a copilot for Next.js and React developers. Glass appears as a chat bar on your locally running Next.js server, and you can tell it to make changes like "build a dashboard" or "add a login button". Glass makes the changes to your sourcecode in real-time. Our goal with Glass is to automate away the easy but slow parts of frontend development, like locating the right file to edit, writing tailwind by trial-and-error, and copy-pasting boilerplate from Claude and other tools. We want to let you do all the tedious work entirely from your browser.…
