Strengths and limits
JetBrains AI Assistant
Strengths
- Work in a familiar IDE: The assistant is integrated with supported JetBrains products rather than requiring a separate coding editor.
- Inspect suggestions before applying: Chat mode supports a deliberate review step for generated code.
- Choose the context: Files and symbols can be attached to focus a question on a specific change.
Limits to plan around
- Free-tier IDE restrictions: AI Free is unavailable in Android Studio and specified free/community IDE editions; check the exact product and license.
- Cloud budget varies by task: A long conversation or agent run can use more credits than a short code explanation.
- AI and IDE licenses differ: An AI subscription does not replace the required IDE license; bundled entitlements depend on the product.
Gemma 4
Strengths
- Permissive license: Apache 2.0 allows commercial use, modification and redistribution without a separate Gemma agreement.
- Runs offline: Downloaded weights work without an account or network connection once installed.
- Published memory table: Google lists approximate memory for every size at 16-bit, 8-bit and 4-bit precision.
Limits to plan around
- Hardware is your cost: The 31B model needs 17.5 GB even at 4-bit, before context memory.
- No paid hosted tier on the Gemini API: The pricing page lists only a free tier, and free-tier content is used to improve Google products.
- Older training data: The pre-training data has a January 2025 cutoff, so later events need to be supplied in the prompt.

Comparing tools from different categories is fine, and often useful — a writing assistant and a research tool solve different halves of the same job. The table will show you exactly where they diverge.
Questions about comparing tools
How does the comparison work?
Add two tools to the comparison tray from any tool card, then open this page. The table pulls each tool's verified plan details, platforms, strengths and limits from its profile, so both columns carry the same kind of evidence, with a separate source-check date for each tool.
Do you declare a winner?
No. The table sets two tools against each other on documented facts, not on a score. Which one wins depends on your task, your budget and your usage volume — three things we cannot see from here.
Why are some cells empty or marked unverified?
Because we could not confirm that detail on the vendor's own pages. Rather than filling the gap with a figure from elsewhere, we mark it and say why on the tool's profile.
Can I compare more than two tools?
Not at once. Two columns keep the differences readable and force a real decision. Remove either selected tool to replace it, or clear both to start a new pair.
Every figure in the table above comes from the linked profile, where the source and the verification date are listed. Browse all tools or read the editorial policy.
