24 alternatives to CopilotTextarea: <Textarea/> W GPT Completions Like Gmail/GitHub. OSS
`` 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…

I got frustrated with Gmail's lack of customization, and built an extension for myself. It doesn't do much other than modify how Gmail is displayed in Chrome. Does it as minimally as possible (that I can engineer). Done locally, zero remote processing. Currently built the following settings (want to add more soon): Conversations: * Show newest message first * Show every message in a thread (sometimes they're collapsed into numbered bubbles) * Remove AI overviews (retches) Layout/UI: * Minimize the search & top bar * Minimize the far left "rail" (Mail/Chat/Meet) * Hide a bunch…

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…

GPTRecap▲134I always loved seeing my Spotify Wrapped every year and wondered why doesn’t ChatGPT have something similar? So I built GPTRecap: paste your exported file and instantly see your top topics, total messages, and more. All core features run 100% in your browser, no account, no data stored. Premium insights (like deeper topic analysis) are processed via OpenAI, but nothing is saved on our servers. Would love feedback! What stats would you want to see next?

CopilotKit is comprehensive copilot infrastructure for react apps. Fully open-source. Just added CopilotTextarea - a drop-in replacement for that supports context-aware copilot-style autocompletions with any LLM/backend. Also coming up for CopilotTextarea (VERY soon): rich text support, and cursor-style insertions/edits.

Hey HN! I built SimplePDF Copilot: an AI assistant that can interact with the PDF editor. It fills fields, answers questions, focuses on a specific field, adds fields, deletes pages, and so on. It's built on top of SimplePDF that I started 7 years ago, pioneering privacy-respecting client-side pdf editing, now used monthly by 200k+ people. As for the privacy model: the PDF itself never leaves the browser. Parsing, rendering, and field detection all run client-side. The text the model needs (and your messages) goes to whatever LLM you point at. By default that's our demo proxy (DeepSeek V4…

ChatIDE is a sort of a DIY Github copilot X. Launch ChatIDE with a `Cmd + Shift + i`. You bring your own OpenAI api key. You can set the system prompt, temperature, and max tokens in the extension settings. The extension is currently not aware of any of the files in your project, although that might be cool to add later. Use it just like you would use ChatGPT in the browser. Feedback and contributions more than welcome.

This project was born from my passion for every Apple product and the entire ecosystem, along with the power of ChatGPT. I was tired of copy-pasting and switching between apps on my Mac or iPhone, so I had this crazy idea to bring ChatGPT into every app that I use. This was possible only with the Apple Shortcuts app. Very few people know about its power and potential, so I took this chance and built COPILOT. https://meetcopilot.app But I also loved the idea of AI agents using various tools so much that I leveraged OpenAI's function-calling feature to accomplish that. Now, no matter…

Hey HN! We’ve been experimenting with integrating multimodal models directly into creative workflows, and ended up building an AI-first image editor using OpenAI’s new `gpt-image-1` (from GPT-4o) inside our SDK. Instead of prompting in ChatGPT and pasting outputs into a design tool, this lets you generate, edit, and remix images all in one canvas. This allows for really interesting new workflows, like quickly mixing multiple images, or creating visual prompts by using annotations and reference on the canvas. Some key details: - Built with our plugin system in CE.SDK (CreativeEditor SDK) -…

Hey, HN! I was trying to find a good Copilot alternative since my experience with copilot degraded a lot and recent OpenAI drama leaves me no hope for improvement and i decided to take a look at self-hosting options. At the same time Copilot net is a small one - just 12b parameters and 2k of context. You can run much bigger networks locally in 2023. I have figured out that there are no good local options: most of the VS Code plugins simply connect neural networks to the code while copilot has extensive post and pre processing steps. Some of them still work with original copilot plugin (ie…

I built a browser extension called Gitcasso which: - Adds markdown syntax highlighting to GitHub textareas - Lists every open PR/issue tab and any drafts - (Optional, unimplemented) autosaves your comment drafts so you don’t lose work I made it because I was impressed by https://overtype.dev/ (a markdown textarea syntax highlighter) which went big on here on HN a few weeks ago, and it seemed like a perfect fit for a GitHub browser extension. Keeping up with changes on upstream GitHub would normally be a pain, but with with Playwright and Claude Code it seemed possible for…

Open-Source, GitHub Copilot Alternative for VS Code

Github Copilot is a great tool for leveraging GPTs while coding, but I find that it is too “open loop” for more complex tasks that require Q&A, feedback to guide it in a particular direction, iteration on code execution errors, etc. There is a large class of tasks that are better accomplished in an iterative, stateful chat-like interface. I have been experimenting with a local command line chat interface to GPT-4 and my mind was blown once again a few days ago when I copied documentation for a pretty involved API into the model context and managed to chat-guide GPT-4 to implement the API in…
