Estology vs. JSTFYD
JSTFYD scans an estimate against codes and standards, flags discrepancies with a dollar figure attached, and auto-drafts negotiation emails back to the adjuster. It requires a user to first build their own documentation library (local codes, state regulations, manufacturer specs) before the AI can cite from it. Pricing is published as five monthly credit tiers, from $99/mo (Solo, 250 credits) to $3,299/mo (Enterprise, 10,000 credits), with a demo booking pushed alongside each tier.

Questions about Estology and JSTFYD.
Do I need to prepare anything before using JSTFYD?
+
Per JSTFYD's own site, yes -- it asks users to upload their own library of local codes, state regulations, and manufacturer specs before its AI can cite them. Estology's Compare works directly from the two estimate PDFs, no separate documentation project required.
What does Estology's AI narrative do differently?
+
Every figure the narrative states is checked against the parsed estimate fact sheet before it's shown -- a number the model didn't already have is rejected rather than written. Review's grading involves no AI at all; it's a deterministic rubric.
What people say after
a real project.
Unedited feedback from contractors, carriers, adjusters, and estimators who use Estology.
"Used Estology on a $47,000 water loss. It found the missing line items and price drift in about ten minutes. The carrier accepted the supplement the same day."
"As a general contractor, I used to spend hours cross-referencing estimates. Now I upload both PDFs and have a defensible line-by-line report before lunch."
"I needed to explain why the contractor's estimate was higher than ours. Estology gave me a clear, sourced breakdown that both sides trusted."
"We had three competing estimates on one file. Estology showed exactly where each one differed and why, so the negotiation took one call instead of five."
"My position letter practically wrote itself. Every variance was sourced back to the original estimate pages, so the adjuster had nowhere to push back."
"I caught $12,000 in dropped scope the adjuster missed. Without a side-by-side comparison, that would have come out of my pocket."
