Show HN: ThinkReview open source browser Copilot GitLab and ADO PRs(Ollama) (github.com)

ThinkReview is an open‑source, production-ready Chrome extension that adds AI-powered code reviews and a conversational “Copilot” directly into GitLab merge requests and Azure DevOps pull requests. The project—now available on GitHub under AGPL‑3.0—offers instant cloud reviews via Google Gemini (no setup) or a 100% local option using Ollama (≈5‑minute setup) to run models on your own hardware. Features include automatic MR/PR detection, interactive chat with PRs, suggested follow‑up questions, security/vulnerability detection, code quality metrics and multi‑language summaries. It supports gitlab.com, self‑hosted GitLab, dev.azure.com and custom Azure DevOps domains, and integrates with OAuth/HTTPS and Azure PATs for private repos. Technically, ThinkReview is a Manifest V3 extension (content scripts, UI components, background service worker) that wires platform detectors to an AI integration layer (cloud or ollama-service). Important caveat: the public extension currently connects to ThinkReview backend services by default; the team offers licensing options for running a private backend if you need fully self‑hosted deployment. The project emphasizes minimal permissions, no stored API keys in the extension, and community contributions—making it useful for teams wanting instant, extensible code review automation but who should still evaluate backend/hosting choices for strict privacy or compliance needs.
