Highlights
Voice-driven pair programming
Voice Mode lets you talk through architectures hands-free. Useful when you're thinking, walking, or rubber-ducking a thorny bug at 11pm.
API access, on the same credits
Hit our API at api.krater.ai with the same models you use in chat. One credit pool covers IDE plugins, scripts, agents — no per-product API subscriptions.
Long-context whole-repo reasoning
Drop a folder into Keep, paste a 200K-token codebase into Gemini 3 Pro, or ask Claude Opus 4 to plan a multi-file refactor. Your code stays in your workspace.
Use cases
Code review on every PR
Paste a diff. Get a senior-level code review from Claude Sonnet 4.6 — bugs, edge cases, style, performance — in seconds. /code
Multi-file refactor planning
Describe the refactor. Claude Opus 4 plans the order of operations, then walks you through each file. Long-context, no context loss.
Debug at the speed of thought
Voice-mode through the stack trace while you scroll the code. Hands stay on the keyboard. Voice Mode
API agent for batch tasks
Run nightly summaries, log triage, or doc generation through api.krater.ai. Same models, same credits, no second contract. API
Compare model output side-by-side
Same prompt to GPT-5, Claude Sonnet 4.6, and Gemini 3 Pro. Pick the answer that actually compiles.
Docs and tests on demand
Paste a function. Get JSDoc, unit tests, and an integration test — written in your project's style.
Workflow
- Pick your model: Claude Sonnet 4.6 for daily work, Opus 4 for architecture, GPT-5 Codex for tough generations. Or let the auto-router pick.
- Bring your context: Upload files, paste diffs, or @mention saved snippets from Keep. Models share the same context.
- Ship with confidence: Get reviews, tests, and refactor plans. Copy code straight into your editor — or hit the API from your CI.
- Scale across the team: Share saved prompts and slash commands. Max plan covers a small engineering team; Enterprise adds SSO and dedicated support.
Frequently asked questions
How is Krater different from GitHub Copilot or Cursor?
Copilot and Cursor are IDE-bound — they live inside one editor and ship one (or a few) models. Krater is the workspace around your IDE: every frontier coding model (Claude Sonnet 4.6, GPT-5 Codex, Gemini 3 Pro, Grok 4, DeepSeek R1), voice mode, API access, image/video/voice — on one credit pool. Many developers use Cursor + Krater together: Cursor for in-editor completion, Krater for architecture, code review, and everything else.
Which model is best for code on Krater?
For most daily work: Claude Sonnet 4.6. For complex architecture and multi-file plans: Claude Opus 4.6 or Gemini 3 Pro (long context). For raw code generation and edge-case reasoning: GPT-5 Codex. For low-cost batch tasks: DeepSeek R1. Run the same prompt to all four and pick — Krater makes that one click.
Can I use the Krater API in production?
Yes. api.krater.ai is OpenAI-compatible — point your SDK at it, pass your Krater API key, and you get the full 350+ model catalogue with one billing relationship. Credits are shared with your chat usage so you have one budget to monitor.
Does Krater have IDE integrations?
Krater is OpenAI-compatible, so any tool that supports OpenAI (Cursor custom models, Continue.dev, Cline, aider, Zed) can point at api.krater.ai. You get every model on Krater with one API key.
How does pricing work for heavy code use?
Krater charges by actual model cost × 200 (so a $0.01 model call costs 2 credits). Pro at $20/month gets 1,500 credits, Ultra at $49 gets 4,000, Max at $119 gets 10,000. Heavy users on Sonnet 4.6 and DeepSeek R1 typically land on Ultra; teams using Opus 4 and GPT-5 Pro daily go to Max or Enterprise.
