Comparison
Mirage vs Helonic
Helonic reviews 2D construction drawings for coordination, code, and constructability conflicts before a bid goes out. Mirage automates construction document workflows end to end, including takeoff, bid leveling, specifications, and compliance. The overlap is real but narrower than the query suggests.
Executive Summary
Helonic and Mirage both read construction drawings with AI, but they're built to answer different questions. Helonic is a pre-bid drawing-review tool: point it at a 2D PDF set and it flags coordination issues, code problems, and constructability conflicts, no BIM model required — the kind of review an estimator or a design reviewer would otherwise do by eye before pricing a job.
Mirage is a forward-deployed agent covering the fuller construction document lifecycle: quantity takeoff, bid leveling, RFIs and submittals, specification review, change orders, pay applications, and compliance checks, each wired into your existing plan formats and estimating workflow by Mirage engineers.
In practice, teams evaluating both aren't always choosing one over the other. Helonic's own materials describe it being used alongside a takeoff tool like Togal.AI, not as a replacement for one — the same complementary relationship applies to a takeoff-and-beyond platform like Mirage.
Key Takeaways
- Helonic is a pre-bid drawing-conflict review tool, not a takeoff or estimating platform.
- Mirage covers the fuller construction document lifecycle: takeoff, bid leveling, RFIs, specs, change orders, pay applications, compliance.
- Helonic's own positioning describes it running alongside a takeoff tool, not replacing one — a complementary relationship, not a straight substitute.
- Helonic is self-serve and YC-backed; Mirage is a forward-deployed agent, scoped and priced per engagement.
At a Glance
| Aspect | Mirage | Helonic |
|---|---|---|
| What it does | Construction document automation: takeoff, bid leveling, RFIs, specs, change orders, pay applications, compliance | Pre-bid 2D drawing review: coordination, code, and constructability conflict detection |
| Model | Forward-deployed AI agent, wired into your existing plan formats and estimating workflow | Self-serve AI drawing-review tool, uploaded and run by your own team |
| Output | Structured, source-traced data pushed into your estimating software and ERP | A flagged list of conflicts and issues found in the drawing set |
| Does it produce quantities or a takeoff? | Yes — that's the core of Mirage's Takeoff & Estimating agent | No — Helonic reviews drawings for conflicts, it doesn't measure or price |
| Typical use alongside a takeoff tool | Not applicable — takeoff is a Mirage workflow itself | Commonly paired with a separate takeoff tool such as Togal.AI, per Helonic's own materials |
| Deployment time | Under 4 weeks on average to production | Self-serve signup; usable as soon as an account is created |
Key Differences
Drawing review vs. full document automation
Helonic's scope is pre-bid drawing conflicts specifically. Mirage's scope spans the construction document lifecycle: takeoff, bid leveling, RFIs, specification review, change orders, pay applications, and compliance, each its own deployment.
Complementary, not a straight substitute
Helonic's own positioning describes it running alongside a takeoff tool, not replacing one. A team already deploying Mirage for takeoff and estimating would be evaluating Helonic as a possible addition for pre-bid conflict review, not a replacement for what Mirage already does.
Self-serve vs. forward-deployed
Helonic is a self-serve product your team uploads drawings to directly. Mirage's engineers wire the agent into your specific plan formats and downstream systems as part of deployment.
Advantages and Limitations
Mirage
Advantages
- Covers the full construction document lifecycle, not just pre-bid drawing review
- Produces quantities and a structured takeoff, which Helonic doesn't do
- Engineers wire the agent into your existing estimating software and ERP
- Under 4 weeks on average to a production deployment
Limitations
- Pricing is scoped per engagement, not published publicly
- Not a drop-in substitute for a dedicated pre-bid conflict-review pass
Helonic
Advantages
- Self-serve — no deployment engagement required to start
- Purpose-built for pre-bid coordination, code, and constructability review
- Works from 2D PDFs directly, no BIM model required
- Backed by Y Combinator
Limitations
- Doesn't produce quantities, a takeoff, or a priced estimate
- Scoped to drawing review — no coverage of RFIs, submittals, change orders, or compliance
Real-World Use Cases
Teams looking for a full construction workflow, not just drawing review
A team that wants takeoff, bid leveling, RFI tracking, or compliance checking automated, not just pre-bid conflict detection, is looking for what Mirage does, not what Helonic does.
Teams wanting a dedicated pre-bid conflict pass
A team that specifically wants an automated second look at coordination and code conflicts before a bid goes out, alongside whatever takeoff process it already runs, is closer to Helonic's stated use case.
High-volume bidding with tight turnaround
The John Cockerill case study reports 80 to 90% less time on piping takeoff and a fabrication bill of materials produced ten times faster, using Mirage's agent instead of manual measurement.
Mirage Products
Takeoff & Estimating
Mirage's AI agent for construction quantity takeoff — reads plan, section, and detail sheets together and returns quantities with their source attached.
Learn more →Specification review
Cross-references every spec clause against the drawings and re-checks automatically on each revision — the closest Mirage workflow to Helonic's conflict-detection focus.
Learn more →How to Choose
This isn't really a head-to-head choice the way a takeoff-vs-takeoff comparison is. Helonic answers a narrower question — does this drawing set have coordination or code conflicts — while Mirage covers the fuller set of construction document workflows, takeoff included.
A team already running Mirage for takeoff and estimating would be adding Helonic for a dedicated pre-bid conflict pass, not choosing between the two. A team with no automation yet has a broader decision to make about how much of the document workload it wants covered.
