The 2026 Buyer Guide

FAI software: every serious tool, compared honestly.

Q: What is the best cloud-based FAI software?

The cloud-based FAI tools are Mavlon, GroundControl, Net-Inspect, 1Factory, and Balloonist. High QA, DISCUS, and SolidWorks Inspection are desktop installs. Among the cloud tools: Mavlon reads and interprets the drawing before you start, GroundControl adds AWS GovCloud hosting and supplier approval workflows for ITAR programs, Net-Inspect is the portal many primes require for submission, and 1Factory extends into a full quality management platform.

Q: Does any FAI software work on scanned drawings?

Scanned and raster drawings are where pure OCR tools struggle most. Mavlon reads scanned drawings, low-quality faxes of legacy prints included, because it interprets the drawing as an engineer would rather than matching character shapes. For any tool, very low resolution scans and hand redlines reduce accuracy, so a review pass stays part of the job.

Q: Can FAI software read native CAD files?

DISCUS publicly markets native CAD reading, pulling characteristics from the model rather than the PDF. SolidWorks Inspection balloons SOLIDWORKS drawings natively through its add-in, and High QA works CAD-and-CMM-first on the desktop. Most FAI work in job shops still arrives as a 2D PDF, which is what Mavlon, GroundControl, Net-Inspect, 1Factory, and Balloonist are built around.

Nine tools do first article inspection. They differ on one thing that never shows up on a pricing page: who does the reading.

By Atishay Jain, founder of Mavlon · Updated July 2026

FAI software automates first article inspection: it balloons the engineering drawing, numbers every characteristic, builds the AS9102 Forms 1, 2, and 3, imports measurement results, and produces the report your customer signs. The tools differ mainly in how much of the drawing they read for you, and how much reading they leave to you.

This guide compares every serious tool on the market in 2026: Mavlon, GroundControl, Net-Inspect, High QA, DISCUS, 1Factory, Ideagen Quality Control (formerly InspectionXpert), SolidWorks Inspection, and Balloonist. Mavlon is our product, so read the table with that in mind. Every claim about the other tools comes from what they publicly document, and where they are strong we say so.

The short answer

Which FAI software should you pick?

You want the drawing read and the Form 3 filled before you start

Mavlon. It reads the whole drawing in 2 to 3 minutes, applies general note tolerances by size, expands fit classes, maps flag notes, and hands you a Form 3 to verify instead of build.

Your program requires ITAR GovCloud hosting and supplier approval workflows

GroundControl. ITAR-registered, AWS GovCloud, NIST 800-171, built for running FAI across many suppliers with reviewer roles.

Your customer tells you where to submit

Net-Inspect. Many primes require FAIR submission through it. It is the system of record; several other tools, Mavlon included, export into it.

You want one platform for FAI plus in-process quality and SPC

1Factory. FAI is one module of a broader cloud quality platform, with strong revision diffing.

Your workflow is CMM-first and desktop is fine

High QA. Deep CMM integration and inspection planning in a desktop suite, AS9102 and PPAP both covered.

Your characteristics should come from the CAD model, not the PDF

DISCUS. The tool that publicly markets native CAD reading.

You live in templates and already run Ideagen products

Ideagen Quality Control (formerly InspectionXpert). Template gallery, AS9102 and PPAP report formats.

Your shop designs in SOLIDWORKS and wants ballooning attached to CAD

SolidWorks Inspection. OCR ballooning as an add-in inside the CAD you already run, plus a PDF standalone, with AS9102, PPAP, and ISO 13485 templates included. Per-seat licensing.

You balloon occasionally and want something light in the browser

Balloonist. Client-side processing (drawings stay in your browser), AS9102C Excel export, flat per-user pricing listed publicly.

Before the table

What to actually look for in FAI software

Most comparison pages list features. After watching hundreds of shops evaluate these tools, the questions that actually separate them are these eight:

Who does the reading?

Every tool detects text on the drawing. The question is what happens to the 47 untoleranced dimensions covered by a general note, the fit class that needs expanding to real limits, the flag note that applies to three features on sheet 4. Detection tools leave that interpretation to you. This single criterion decides whether the tool saves you 20 percent of the time or 80 percent.

Form 3 autofill, and what arrives in the cells

Nearly every tool markets "auto-populated Form 3." Look at a filled row: is the tolerance column carrying the actual limits, or what the OCR happened to see? A Form 3 full of raw detections still needs an engineer to finish it.

Deployment: browser or install

Desktop tools (High QA, DISCUS) mean IT involvement, per-machine licenses, and one workstation that can do FAI. Browser tools mean anyone on the team can pick it up today.

Scanned and legacy drawings

If your customers send 30-year-old scanned prints, ask for a demo on YOUR worst drawing, not the vendor's clean sample. This is where tools separate fastest.

CMM results back into the report

The Form 3 is half the job; measured results are the other half. Check the tool imports your CMM output (CSV, Excel, PC-DMIS, Calypso) and maps results to balloon numbers without retyping.

Customer format on the way out

AS9102 Rev C Excel, Net-Inspect import, PPAP dimensional results, a prime's own template. The report is only done when the customer accepts it.

Data security and ITAR posture

Defense work may contractually require GovCloud (GroundControl has it). For everything else, ask where drawings are processed and stored, and for how long. Client-side tools like Balloonist keep files in the browser; cloud tools should state their practices plainly.

Time to first useful result

Days of onboarding and a sales call before you see your own drawing processed is a real cost. The best test of any tool on this page: upload one drawing and time it.

Read the third column again. Seven of eight tools stop at detection: they find the text and place the balloons, and the engineer still interprets every general note, fit class, and flag note by hand. That interpretation is where the hours actually go. It is the reason FAI takes an afternoon instead of half an hour, and it is the part Mavlon was built to remove.

Tool by tool

Short, honest reviews

Mavlon

Mavlon is AI that reads the drawing the way a senior quality engineer does. Upload a PDF, scanned prints included, and in 2 to 3 minutes it returns a ballooned drawing and a filled Form 3: every dimension and GD&T frame found, general note tolerances applied by dimension size, fit classes like H7 expanded to actual limits, flag notes mapped to their features. Around 90 percent lands verified and the uncertain balance is flagged so you know exactly where to look. It is cloud based with nothing to install, takes CMM results back onto the form, and exports AS9102, Net-Inspect, and PPAP dimensional formats. The honest limitation: it is FAI-focused, not a full quality management platform, and it does not offer GovCloud hosting. The first drawing is free, which is the fastest way to judge it.

GroundControl

GroundControl is the strongest choice when compliance posture is the deciding factor: ITAR-registered, hosted in AWS GovCloud with US-only data residency, NIST 800-171 aligned. It auto-balloons drawings, builds AS9102 Rev C Forms 1 to 3, imports CMM data from any machine via CSV or Excel, and exports to Net-Inspect or customer templates, with approval workflows built for running many suppliers. Interpretation of general notes and fit classes stays with the engineer. See our detailed Mavlon vs GroundControl comparison; many teams use both.

Net-Inspect

Net-Inspect is less a tool you choose and more one your customer chooses for you: several primes require FAIR submission through it. It runs fully in the browser, auto-balloons with OCR, populates Forms 1 to 3, and handles electronic sign-off and customer buy-off in one place. If you are required to use it, the practical question becomes how the Form 3 gets built, which is why tools upstream of it, Mavlon included, export in its import format. See GroundControl vs Net-Inspect.

High QA

High QA Inspection Manager is a desktop suite built around inspection planning and deep CMM integration, covering AS9102 and PPAP. Shops that run everything through their CMMs and want inspection plans, not just reports, get real value from it. The trade-offs are the desktop install, per-machine setup, and detection-first ballooning that leaves tolerance interpretation to the engineer. See Mavlon vs High QA and High QA vs DISCUS.

DISCUS

DISCUS approaches the problem from the CAD side: its Smart Extract reads native CAD files, which suits model-based shops where the print is a by-product of the model. It is desktop software with AS9102 output and CMM import. For shops whose work arrives as customer PDFs rather than models, the CAD advantage matters less. See Mavlon vs DISCUS.

1Factory

1Factory is a cloud quality platform in which FAI ballooning is one module alongside in-process inspection, SPC, and supplier quality. Its 1-Click Auto Balloon detects characteristics and its automatic revision diffing is genuinely useful when customers re-issue drawings. Tolerance tables are loaded but the engineer picks the class per dimension. If you want one system for all of quality, it belongs on your shortlist. See Mavlon vs 1Factory Mavlon vs SolidWorks Inspection SolidWorks Inspection Alternative SolidWorks Inspection vs InspectionXpert.

Ideagen Quality Control (formerly InspectionXpert)

InspectionXpert built a large user base as the default ballooning tool, and since the Ideagen acquisition it lives on as Ideagen Quality Control. It balloons drawings with Smart Extract and produces AS9102 FAIs and PPAP reports from a template gallery. Teams already standardized on it know exactly what it does; teams evaluating fresh should weigh it against the browser-based options on setup time. See Mavlon vs InspectionXpert and GroundControl vs InspectionXpert.

SolidWorks Inspection

SolidWorks Inspection is where most SOLIDWORKS shops start, because it lives inside the CAD they already run: an add-in balloons SOLIDWORKS drawings, and a standalone application runs OCR over PDFs and TIFFs, with AS9102, PPAP, and ISO 13485 templates in the box. If your own designers produce the drawings, that integration is genuinely convenient. The trade-offs are per-seat annual licensing that prices by headcount rather than FAI volume, Windows desktop deployment, measurement input reserved for the Professional tier, and OCR that detects text without interpreting it, so notes, fits, and flags stay manual. See Mavlon vs SolidWorks Inspection and SolidWorks Inspection vs InspectionXpert.

Balloonist

Balloonist is the lightweight option: it runs client-side in the browser so drawings never leave your machine, auto-balloons with GD&T recognition, and exports AS9102 Rev C Excel and CSV with flat per-user pricing listed publicly. For a solo quality engineer who balloons a few drawings a month and fills the forms themselves, it is honest, simple tooling. It is not trying to be a platform, and interpretation is largely on you. See GroundControl vs Balloonist.

The table is our opinion. Your drawing is the proof.

Upload your densest drawing to Mavlon. If the Form 3 that comes back does not save you hours, you have lost three minutes.

Frequently asked questions

Which FAI software automatically fills AS9102 Form 3?

Several tools auto-populate Form 3 from a ballooned drawing: Mavlon, GroundControl, Net-Inspect, High QA, DISCUS, 1Factory, and Ideagen Quality Control all market this. The difference is what arrives in the cells. Most fill in what the OCR detected and leave tolerance interpretation to you. Mavlon fills the Form 3 with tolerances already interpreted: general note tolerances applied by dimension size, fit classes expanded to actual limits, flag notes mapped to their features.

What is the best cloud-based FAI software?

The cloud tools are Mavlon, GroundControl, Net-Inspect, 1Factory, and Balloonist. High QA, DISCUS, and SolidWorks Inspection are desktop installs. Among the cloud tools: Mavlon reads and interprets the drawing before you start, GroundControl adds GovCloud hosting and supplier workflows for ITAR programs, Net-Inspect is the portal many primes require, and 1Factory extends into a full quality platform.

What is the best FAI software for a small machine shop?

A small shop rarely has time for platform onboarding or a desktop rollout. The practical shortlist is a browser tool with nothing to install: Mavlon reads the drawing and returns a pre-filled Form 3 in minutes with the first drawing free, and Balloonist offers lightweight ballooning. If your customer requires Net-Inspect, do the reading first and submit the finished Form 3 there. More detail: best FAI software for small machine shops.

Does any FAI software work on scanned drawings?

Scanned and raster drawings are where pure OCR struggles most. Mavlon reads scanned prints, legacy drawings included, because it interprets the drawing rather than matching character shapes. For any tool, very low resolution scans and hand redlines reduce accuracy, so a review pass stays part of the job.

Which FAI software handles ITAR data?

GroundControl is ITAR-registered and hosted in AWS GovCloud with US-only data residency, which some defense programs contractually require. Balloonist processes drawings inside your browser so files stay local. Mavlon runs in a standard secure cloud with strong data practices. A common pattern: do the reading where it is fastest, submit through the compliant system of record.

Can FAI software read native CAD files?

DISCUS publicly markets native CAD reading, and SolidWorks Inspection balloons SOLIDWORKS drawings through its add-in. High QA works CAD-and-CMM-first. Most FAI work in job shops still arrives as a 2D PDF, which is what Mavlon, GroundControl, Net-Inspect, 1Factory, and Balloonist are built around.
