About Tessera AI
Tessera AI is a JetBrains plugin designed to assist developers with code generation, refactoring, and documentation directly inside IntelliJ-based IDEs. It supports both cloud and local large language models (LLMs), offering inline completions, multi-line suggestions, bug fixes, and docstring generation. The free tier provides 60 requests per month, while the Pro tier at $8/mo unlocks unlimited requests and advanced models. Tessera currently has no website (the domain tessera.dev is for sale) and no available download or release, making it a pre-release tool. Prospective users should monitor for an official launch; for immediate AI coding assistance, alternatives like GitHub Copilot, Tabnine, or Codeium are readily available.
Behind the Verdict
Tessera AI aims to be a privacy-focused AI coding assistant for JetBrains users, with a unique selling point of local LLM execution. The freemium model is generous: 60 free requests per month and an $8 Pro tier undercuts Copilot's $10/mo. However, the glaring issue is availability. The website is a domain parking page, and there's no plugin to download. We'd only consider it once it ships a stable release. Compared to alternatives, if you need AI help today, go with Copilot, Tabnine, or Codeium. Tessera's potential strengths are local execution and lower cost, but execution is everything. Keep an eye on it, but don't hold your breath.
