| Inline completions | No, it works by instruction rather than by autocomplete: the CLI and the VS Code and JetBrains extensions offer plan review, inline diffs and @-mentions, not tab completions as you type | Yes, in-editor completion of lines and blocks in your coding style, plus chat, code generation, documentation and tests |

Strengths
- Deepest reasoning for complex multi-file and architectural tasks
- Project-level planning

Limitations
- Terminal-first, not a full IDE interface
- Usage limits on Pro, and cost climbs on Max or heavy API use
JetBrains AI Assistant
Strengths
- Deeply integrated into JetBrains IDEs and their refactoring and inspection tools
- One subscription covers AI Assistant and the Junie agent, and external agents can be driven from the same chat
- Local models via Ollama or LM Studio work for chat, generation, commit messages and documentation
- The credit quota is denominated in dollars, so usage is legible before it runs out
Limitations
- Only useful inside JetBrains IDEs, and AI Free is unavailable in Android Studio and the Community editions
- Cloud features are metered by a monthly AI credit allowance, with top-ups sold separately
- The plugin is not bundled and is disabled by default, so it has to be installed and enabled

How we check reviews
Reviews are not published yet. The form on a tool's page works and reaches us, but nothing from it appears on this site, so no score here is based on a review. The rules below are the ones that will apply once reviews go live.
Every review is read by a person before it appears. We require a working email address and use it to come back to the author, so a review has a reachable sender rather than being anonymous. We publish positive and negative reviews alike, we pay nothing and offer nothing for a review, and we accept none that was bought or incentivised.
What we cannot do is verify a purchase. There is no shop here and no account, so whether the author really used the tool rests on what they tell us, plus the plausibility of what they write. We say so rather than implying a check that does not exist.
A vendor cannot have a review removed, cannot buy one, and cannot have one changed. Paid placement and a paid listing have no effect on which reviews appear or on any score.
