⚡JetBrains has released Thinkrail, an open-source AI coding tool.

What it means

JetBrains — the company behind IDEs like IntelliJ IDEA — has released Thinkrail, an open-source AI coding tool, now available on GitHub under JetBrains/thinkrail. It represents a new piece of AI tooling aimed at software development, though the note does not specify whether it is a code-completion engine, an agentic coding assistant, a model, or something else. As an official open-source release, developers can read, modify, and contribute to the code directly.

Accuracy & sourcesSourced

The claim is grounded in a primary source — an official JetBrains release on GitHub — so the existence of the open-source project is solid. However, the item gives no detail on what Thinkrail actually does beyond the category 'AI coding tooling,' so any specifics on its function are inferred, not confirmed.

How new

Genuinely new — this release is presented as current, with no recirculation year suggesting it is resurfaced from older material.

Past coverage

We previously covered JetBrains' Mellum2 open-source coding model in June 2026; Thinkrail is a separate new open-source AI coding tooling release from the same company.
