Ellipsis (YC W24)

Did you know that Ellipsis can automatically write pull requests descriptions? The automated descriptions include context from your product roadmap and the team's recent work. As a developer pushes more commits, the summary will update, meaning that other engineers are always up-to-date on open pull requests.

Why I’m All In on Ellipsis: A Game-Changer for AI Code Reviews & Bug Fixes I just spent weekend trying out Ellipsis (YC W24) (https://www.ellipsis.dev), and I have to say - I’m thoroughly impressed. For those who haven’t heard of it yet, Ellipsis is a smart AI assistant that lives inside your PRs and helps automate everything from code reviews and bug spotting to style guide enforcement and even code generation. Think of it as your new favorite pair programming partner that never sleeps and doesn’t miss a thing. Here’s what stood out to me: ?? Instant, Context-Aware Code Reviews Ellipsis doesn’t just look for syntax issues. It catches logic bugs, smells, and even subtle anti-patterns. It understands the intent behind the code and makes recommendations that actually make sense - not just the typical "nit" suggestions. ?? Smart Q&A Right Inside the PR Need clarification on a function or architectural pattern? Just tag @ellipsis-dev in a comment, and it replies with helpful, relevant answers - almost like having your tech lead on-call 24/7. ?? Adapts to Your Style Guide You can teach Ellipsis your coding preferences in plain English. After that, it flags style violations your way, not just by some off-the-shelf linter. ?? Code Generation & Refactoring That Feels Human Ask Ellipsis to write or refactor code, and it returns fully functional, tested code snippets. Not "AI-generated spaghetti" — real, readable code that’s ready to merge (after your quick sanity check, of course). ??? Secure and Private It’s SOC 2 Type 1 certified, doesn’t store your code, and integrates directly into your GitHub/GitLab workflow with minimal setup. After using Ellipsis across a few real-world PRs, it’s earned a permanent place in my dev toolkit. It reduces the mental load, helps prevent defects earlier, and lets us focus more on architecture and problem-solving. If you're in engineering leadership, an SDET, or even a solo dev trying to scale quality without slowing down, give it a spin. There's a free trial, and I guarantee you’ll be as impressed as I was. ??

?? last night a Sentry alert woke me up at 2am: one of our workers nodes used for codebase indexing was running out of memory. Turns out,?Ellipsis (YC W24) is now installed in a 4GB repository that averages one new commit every ~6 seconds ??

“Ellipsis’s comments feel like they came from a tech lead, not a lintern" – by which he meant a linter turned up to 11.

I must say, its really nice to have tools like Ellipsis (YC W24). Just today i was about to submit a Pull Request into BAML's compiler to improve some of our errors for how we detect duplicate names in various scopes a user types in. Ellipsis was able to detect a really nuanced edge cases that cursor had auto completed wrong. Thanks Nick Bradford! Before -> After

Last week at the Y Combinator alumni retreat, I spoke to fellow AI founders on how we built Ellipsis (YC W24) to automate code review and bug fixes + how our dev workflow changed over the last year, including: ?? Composability is key: breaking hard problems into smaller LLM agents that can be independently benchmarked ???? Evals are all you need: we're investing deeply in annotating data and LLM-as-Judge ???? LLMs can help throughout the dev workflow: for example, on failed test cases, we use an LLM Auditor to auto-diagnose where in the agent's trajectory it went of the rails ?? Reducing false positives in code reviews: we've developed an extensive filtering pipeline to decrease noise and raise trust in the comments we leave, including new ways to leverage customer feedback ...and lots more!
