Products that do what Sweep, AI autocomplete for JetBrains that rewrites code does
Hi HN, I've been a JetBrains user for the last couple of years, and felt that JetBrains was missing a strong autocomplete tool. Over the last 6 months, we've fine-tuned our own model, built our own inference stack, and integrated it deeply into the IDE. You can use the autocomplete plugin for free (no sign up required) on the JetBrains marketplace. Here's how we got here: We started with standard FIM (fill-in-the-middle) autocomplete. Other AI code completion tools in JetBrains can only "add" code at your cursor position. This can be helpful when writing assert statements in unit tests, but…

Hey HN, we trained and open-sourced a 1.5B model that predicts your next edits, similar to Cursor. You can download the weights here (https://huggingface.co/sweepai/sweep-next-edit-1.5b) or try it in our JetBrains plugin (https://plugins.jetbrains.com/plugin/26860-sweep-ai-autocomp...). Next-edit autocomplete differs from standard autocomplete by using your recent edits as context when predicting completions. The model is small enough to run locally while outperforming models 4x its size on both speed and accuracy. We tested against Mercury…

Refact is a Copilot alternative that has an autocomplete, integrated AI chat and powerful editing. We use our own models that are fine-tuned for each language, they are smaller than the one in Copilot, but are very powerful for their size. On certain tasks, you will not notice much difference: the model look up and down, and the context window is the same. Try it for free for JetBrains and VS Code.

Hey HN! I built Retain as the evolution of claude-reflect (github.com/BayramAnnakov/claude-reflect). The original problem: I use Claude Code/Codex daily for coding, plus claude.ai and ChatGPT occasionally. Every conversation contains decisions, corrections, and patterns I forget existed weeks later. I kept re-explaining the same preferences. claude-reflect was a CLI tool that extracted learnings from Claude Code sessions. Retain takes this further with a native macOS app that: - Aggregates conversations from Claude Code, claude.ai, ChatGPT, and Codex CLI - Instant full-text…

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.
