The Aha Moment: Context Compression You Can See

Turn a 50MB file into a 4-line JSON response. Save up to 95% of LLM inference tokens on read-heavy workflows.

Agent Prompt
Agent: "Calculate Q3 revenue from this 50,000-row ledger."
Local CLI Execution
cell fetch --file "Q3_Ledger.xlsx" \
  --sql "SELECT SUM(Revenue) AS q3_revenue \
         FROM data WHERE Quarter = 'Q3'"
Compact JSON Output
{
  "ok": true,
  "data": { "rows": [{ "q3_revenue": 12850420 }] }
}

Use Cases For Builders Who Need Results Fast

Automated Web Scraping to Excel

Use Pro append to stream scraped records into master sheets without overwriting historical rows.

Startup Financial Modeling

Use clone and anchor-based patch for "what-if" scenario analysis without touching fragile formula grids.

Personal Finance Agents

Run local SQL with fetch over bank exports to categorize spending without sending private data to cloud inference endpoints.

One Command Mental Model, Two Capability Tiers

Both editions run as cell. Community handles read-heavy and deterministic query workflows. Pro adds the safety layer required for autonomous agents running on schedules.
