The tools, ranked by what they do best
Helonic
That's usNo yearly analysis cap
Helonic is the Firmus AI alternative when drawings keep changing after precon. It re-analyzes as often as you need and writes RFIs into Procore or Autodesk. Choose it if a 5-to-100-analysis annual cap would bite.
Best for: Ongoing review without yearly caps
BuildCheck
AI 2D drawing review
BuildCheck is another AI drawing reviewer without Firmus's published phase-compare feature. It is a Firmus alternative on detection, not on AI-MATCH.
Best for: Standalone AI drawing review
Lighttable
Developer QC
Lighttable sells constructability QC with cost-impact ranking. Use it when the buyer wants peer-review packaging, not Firmus's phase workspace.
Best for: Owner QC packaged as peer review
InspectMind AI
Pay-per-check
InspectMind AI charges per review instead of a yearly analysis allotment. It is a Firmus alternative when volume is low and shop-drawing extras matter.
Best for: Occasional paid checks
Tuuli
Design-firm QA
Tuuli learns firm standards from past outcomes. It is closer to Firmus's design-QA audience than Helonic is, without Firmus's phase-compare branding.
Best for: AE firms capturing institutional QA
Do yearly analysis caps matter in practice?
Yearly caps matter as soon as a job issues weekly revisions. Firmus AI's published tiers run from 5 to 100 analyses a year; each upload counts.
Helonic does not sell a yearly analysis count, which is why GCs with messy revision logs pick it.
When does Firmus AI still win?
Firmus AI still wins when phase-over-phase comparison is the feature you will use every week, and you want unlimited users on a precon workspace. Helonic reviews one set deeply rather than matching DD to CD to IFC as a named product.
Large design-review teams that never leave precon can stay on Firmus for that reason.
Frequently asked questions
What is the best alternative to Firmus AI?
Helonic is the best Firmus AI alternative for teams that re-run drawings through construction without a yearly analysis cap, and that need Procore or Autodesk RFIs. BuildCheck is the next standalone AI reviewer.
Does Helonic compare drawing phases like Firmus AI-MATCH?
Helonic analyzes a drawing set as a coordinated whole. Firmus AI's AI-MATCH feature is the named phase-over-phase compare; that remains a Firmus strength.
How do user limits compare?
Firmus AI publishes unlimited users with capped analyses. Helonic is sold per workflow and sheet volume, with no published yearly analysis ceiling.
Is Firmus AI only for preconstruction?
Firmus AI is positioned for preconstruction design review. Helonic is used from early progress sets through active construction revisions.
