Helonic alternatives

Buyers ask search engines exactly this, so here is the answer from Helonic's own pages as read on 7 October 2026, with Mirage's side stated where it is relevant. Helonic's figures about itself are its claims.

• Wins: coverage on day one. Ten issue categories and four US codes are available as soon as a set is uploaded, with findings returned in minutes according to Helonic. Mirage's checks are built per deployment and take weeks to reach production.
• Wins: no model required. Helonic works on 2D PDF sets without BIM or 3D models, which is how most bid sets arrive.
• Wins: RFIs where the project runs. Findings become RFIs pushed into Procore or Autodesk Construction Cloud on the Professional plan and above.
• Falls short: no quantities. Helonic does not measure, so a team still needs a takeoff tool or an agent for the estimate.
• Falls short: US only. Nothing is published for UK, French, FIDIC or NEC4 projects, nor for documents other than drawings: quotes, specifications read as text, change orders, pay applications.
• Falls short: price and proof. All three plans are custom-priced, and its 90%+ detection accuracy and $500M+ rework avoided are Helonic's own figures, with no independent benchmark published.
• Open question: on-premise. On-premise deployment is listed on the Enterprise plan only; what the lower plans do with a client's drawings is for Helonic to answer in a security review.

Whichever product you evaluate, Helonic, a competitor or a review step inside a construction platform, these criteria separate a demo from a deployment.

• Which codes and editions. The code years and local amendments your projects fall under, not only the model codes. Ask how a new edition is adopted.
• The categories that matter to your trade. A mechanical subcontractor cares about MEP clashes and constructability; a GC about coordination and missing information. Ask for the category list and what each check actually does.
• Evidence per finding. The sheet, the detail and the clause behind each issue, so a reviewer can accept or dismiss it in seconds.
• False positive rate on your sets. Run a set your team already reviewed by hand and count the findings that were real. Any accuracy figure that is not measured on your own drawings is marketing.
• Where findings go. An RFI in Procore or ACC, a PDF export, or a list nobody opens. The integration decides whether the review changes the bid.
• What happens to the drawings. Where they are processed and stored, who can see them, and whether the vendor trains on them. Written answers, before the first upload.
• Pricing basis. Per sheet, per project, per seat or per plan; whether a pilot is available and what it costs.

On US projects, Mirage reads US drawing sets and returns quantities traced to the sheet for your estimators to price, and runs the document workflows around the bid and the job: CSI MasterFormat organisation of specifications and submittals, certified payroll against prevailing wage determinations and AIA G702/G703 pay applications. It does not review drawings for building code compliance: for that, Helonic is the tool built for it, and the two can run side by side.

On UK projects, quantities can be measured into an NRM2-structured bill, and the contract side covers NEC4 administration. Helonic publishes no UK code coverage. For the estimating manager's view of what the agents take over and what stays with the team, see AI for estimating managers.
