Collimer is an AI-visibility audit platform by Sandcastle Labs. It measures whether AI assistants (ChatGPT, Claude, Gemini, Perplexity, Grok) recommend your brand when buyers ask real buying questions, then diagnoses why competitors get cited instead, prescribes the specific content changes to ship, and re-scans to verify the fix moved the score.

## What we do

Collimer runs every probe repeatedly across five AI models and collimates the results into one calibrated AI Visibility Score (0–100) with a 95% confidence interval shown. Unlike single-run rank checkers, Collimer reports the distribution, not a dice roll. The name comes from the collimator: the optical instrument that aligns scattered light into one true beam.

## Products / Services

**Collimer Scan**: a free public scan of any brand's AI visibility, with a shareable report. No signup.

**Pricing**: Collimer's scan is free, no signup. Ongoing work starts at $6,500 fixed price, the 2026 founding rate.

**GEO Sprint ("Work with us")**: a 90-day done-with-you engagement - measure, ship the ranked fixes, re-scan, prove the delta. $6,500, fixed price, the 2026 founding rate (it goes up in 2027). This is how most teams take ongoing work: scan first, then a call, then the sprint.
