Grainulator
Research that compiles.
Ask a question. Get a multi-pass investigation with typed claims, tension detection, and a confidence-graded answer. Not a chatbot — a research sprint that runs in under 60 seconds.
What it does
- Multi-pass investigation — 3 research passes build evidence from different angles before synthesizing an answer
- Typed claims, not vibes — every finding is tagged as factual, constraint, risk, recommendation, or estimate with an evidence tier (stated / web / documented / tested / production)
- Tension detection — the compiler finds contradictions between claims and surfaces them before generating output
- Confidence scoring — a 7-pass compiler grades evidence strength, type coverage, and bias to produce a 0-100 confidence score
Try the demo
grainulator.app runs a sprint in your browser. Type a question, watch three research passes execute, and see the compiled answer with claim breakdown.
What to expect from a single sprint:
| Metric | Typical value |
|---|
| Claims generated | 12-16 |
| Claim types | 5 (factual, constraint, risk, recommendation, estimate) |
| Tensions detected | 3-6 |
| Evidence tiers | web, documented, stated |
| Confidence score | 63-68 / 100 |
| Time to answer | 40-70 seconds |
The demo runs client-side to show the pipeline. The real tool (installed as a plugin) uses Claude for substantially higher quality research and deeper evidence.
Install
Step 1 — Add the marketplace (one-time setup):
/plugin marketplace add https://github.com/grainulation/grainulator/blob/main/.claude-plugin/marketplace.json
Step 2 — Install the plugin:
/plugin install grainulator
That's it. The plugin registers MCP servers, skills, hooks, and an autonomous agent.
Requirements: Claude Code with Node.js >= 20.
Alternative: clone directly
git clone https://github.com/grainulation/grainulator.git ~/.claude/plugins/grainulator
claude plugin add ~/.claude/plugins/grainulator
SSH permission denied? If you see git@github.com: Permission denied (publickey):
git config --global url."https://github.com/".insteadOf "git@github.com:"
Then retry the install. This tells git to use HTTPS instead of SSH for GitHub repos.
Team deployment
Commit to your project's .claude/settings.json:
{
"enabledPlugins": ["grainulator@grainulation-marketplace"]
}
For air-gapped environments, use CLAUDE_CODE_PLUGIN_SEED_DIR with the plugin baked into container images.
How it works
You ask a question. Grainulator runs a research sprint.
The sprint has two phases:
1. Investigation (3 passes)
Each pass approaches the question from a different angle — constraints, risks, alternatives — and produces typed claims. Claims accumulate
