1Factory vs High QA: Two OCR Tools, and the AI That Reads the Drawing

The first time I watched a quality engineer balloon a first article report, it was a Thursday afternoon and the drawing was an aerospace bracket, three sheets, A2, scanned slightly crooked. She had the PDF on one monitor and the FAI software on the other. She clicked a dimension. The tool guessed the value. She corrected it. She clicked the next one. It missed the tolerance. She typed it in. She got to a feature control frame and the software gave her the geometric symbol and the value, but not the datum reference frame, so she pieced that together by eye. Two hours in, she was on sheet two. There was a general tolerance note in the title block that governed half the unmarked dimensions, and she was applying it by hand, one feature at a time, checking the size band for each.

She was not slow. She was excellent. The software was just making her do the reading.

That afternoon is the whole reason this article exists. If you are comparing 1factory vs high qa, you are standing where she stood: you have a backlog of drawings, a customer who wants the Form 3, and a sense that the tool is supposed to be helping more than it is. So let me be useful. I will give you a fair, specific account of both. Then I will tell you about a third option that does not belong in the same category at all.

Why you are searching this in the first place

Nobody compares first article inspection tools for fun. You are here because something is not working. Usually it is one of three things.

You are drowning in ballooning. Every FAI starts with someone numbering features on a drawing and transcribing them into a report. It is the least glamorous, most error-prone hour of the quality job, and it scales linearly with your order book. More work means more ballooning, and more ballooning means more headcount.

You are evaluating a platform and the names that come up are 1Factory and High QA. Both are real, established, capable companies. Both show up in aerospace and defense shops. Both will sell you ballooning as part of a larger story.

Or you already own one of them and the ballooning step still feels manual, so you are wondering whether the other one is better. That is the honest version of the 1factory vs high qa question, and the answer is not what you expect.

Before going further: this comparison is fair. 1Factory and High QA are good at real things, and I will say so plainly. But the framing matters more than the scorecard, so let me hand you the framing first.

The reframe: this is not a contest between two tools

Here is the thing that took me too long to see. The interesting question is not which of these two OCR tools is better at ballooning. The interesting question is whether you should be using OCR to read your drawings at all.

That sounds like a technicality. It is not. It is the entire game.

Both 1Factory and High QA read your drawing with optical character recognition. They say so themselves, in their own marketing. 1Factory describes its auto-ballooning as traditional OCR. High QA describes its 2D ballooning as smart OCR. Different adjectives, same underlying machine: a system that scans the page for characters and tries to turn pixels into text.

That is a 2010s answer to a 2025 problem. And there is now a different kind of system: one that does not detect characters but reads the drawing, the way an engineer reads it. That system is Mavlon, and it is the reason the 1factory vs high qa debate is the wrong debate.

Let me explain the difference plainly, because it is the spine of everything below.

OCR versus AI, explained without the jargon

OCR finds text. You point it at a region of a drawing and it returns the characters it sees: a string like "12.5 H7". That is genuinely useful, and OCR has gotten good at it. But notice what OCR does not do. It does not know that 12.5 H7 is a hole with an ISO 286 fit class that expands to a specific upper and lower limit. It does not know that the unmarked 40 mm edge inherits a tolerance from a general note in the title block, and that the band depends on the feature size. It does not know that a feature control frame is a sentence with grammar: a geometric characteristic, a tolerance zone, and a datum reference frame that has to be assembled in order. OCR sees text. The interpretation is left to the human.

AI reads. When Mavlon looks at a drawing, it does not just lift characters off the page. It interprets the drawing as an engineer would. It recognizes that 12.5 H7 is a fit and expands it to real limits. It sees the ISO 2768 note and applies the right tolerance band to each unmarked dimension by its size. It captures a GD&T callout as a complete datum reference frame, not a loose pile of symbols. It takes a note written on sheet one and carries it onto the tolerance it governs on sheet three.

This is the iPhone versus BlackBerry moment for inspection software. The BlackBerry had a keyboard and did email well. The iPhone did not have a better keyboard. It removed the keyboard and changed what a phone was. OCR ballooning is the keyboard. It is a better way to do the old thing. Reading the drawing is the new thing.

And this is not spin. The incumbents told you they use OCR. Mavlon's claim is simply that detecting characters and reading a drawing are different acts, and the difference is the whole product. If you want the broader landscape, here is auto ballooning software for aerospace FAI compared.

What it looks like on a real drawing

Abstractions are easy to nod along to and hard to feel. So picture the bracket from that Thursday afternoon, and watch what reading actually does.

There is a general tolerance note in the title block: ISO 2768-m. It governs every dimension on the drawing that does not carry its own tolerance, and the band it applies depends on the feature size. A 6 mm dimension gets one tolerance. A 120 mm dimension gets a wider one. An OCR tool reads the note as text and hands it to you; you apply the bands yourself, feature by feature, checking each size against the table. Mavlon reads the note, then walks the drawing and applies the correct band to each unmarked dimension by its size, automatically. That is the difference between detecting "ISO 2768-m" and understanding what it does.

There is a bore called out as 9 G6. To an OCR system that is four characters. To an engineer it is an ISO 286 fit class that expands to a real upper and lower limit. Mavlon expands it. The Form 3 gets the limits, not the shorthand.

There is a feature control frame: position, a tolerance zone, datums A, B, C in order. OCR can often pull the symbol and the number. The datum reference frame, the part that tells the inspector what the zone is measured from, is the part that gets dropped or hand-assembled. Mavlon captures the full frame as one structured callout.

And there is the note on sheet one that governs a tolerance on sheet three. A human remembers it, flips back, applies it. OCR has no memory of one sheet while it looks at another. Mavlon carries the note across the sheets to the feature it governs.

Add to that the drawings that do not cooperate: the scan that came in crooked, the photograph someone took on the shop floor, the European drawing that writes 12,5 instead of 12.5. Mavlon reads those too. It handles six tolerance standards in all: ISO 2768 linear, angular, and chamfer; ASME Y14.5 GD&T; ASME decimal-place notes; ISO 286 fits; ISO 13920 for welded parts; ISO 9013 for thermal cutting.

For context on what 1Factory publicly markets: its documentation calls out ISO 2768 coarse and medium. That is a real capability. Mavlon reads the six standards above. I am not telling you the incumbent fails. I am showing you the surface area, and letting the gap speak.

What Mavlon actually is

Mavlon is AI drawing intelligence. The plain way to say it: you hand it a drawing, and it acts like an AI quality engineer.

You upload a PDF in your browser. No install, no desktop client, no IT ticket. In about two to three minutes it reads the drawing, auto-extracts the notes, auto-places the balloons, and fills out the AS9102 Form 3. It captures GD&T with full datum reference frames, applies ISO 2768 by feature size, expands fit classes to real limits, and carries notes across sheets. It reads at roughly 90 percent accuracy and flags the remaining ten percent it is unsure about, so you review what matters instead of checking everything.

Two clicks. That is the interaction. The reading is the product.

These are our numbers, stated as ours: about 90 percent, about two to three minutes, six standards. I am not presenting them as third-party verified. I am presenting them as what we built and what we measure.

1Factory vs High QA vs Mavlon, side by side

Here is the comparison without the marketing gloss. No price row, because price is not the point and it changes nothing about how the drawing gets read.

If you want the deeper one-on-one breakdowns, here is the High QA alternative and here is the 1Factory alternative.

Where the incumbents genuinely fit

This is the part where a fair comparison earns its keep, so I am going to be straight with you.

1Factory is a full quality management platform. Ballooning is one room in a large house. It does statistical process control, gage management, PPAP, CAPA, the whole quality system. If your problem is "I need an enterprise QMS and inspection is one piece of it," 1Factory is a serious answer. It is bought the way platforms are bought, through a sales conversation and a rollout, so it is a platform decision, not a quick trial.

High QA is a modular inspection suite with smart OCR ballooning at its core. It is established, it is built for quality teams, and shops use it in production every day. It is a sales-led platform, so evaluating it usually means a call before you see it work rather than a self-serve trial in the browser.

Both of these are mile-wide tools. They cover enormous surface area across the quality function. That breadth is a genuine strength if breadth is what you need.

Mavlon is mile-deep on one thing: reading the drawing. It does not try to be your QMS. It does the single hardest, most manual step in the FAI, the ballooning and the Form 3, and it does that step by actually reading the drawing instead of detecting text on it. And it plays nicely with the rest. The Form 3 Mavlon produces is meant to feed straight into the system you already run, whether that is 1Factory, High QA, or your own. You are not replacing your quality system. You are replacing the two hours someone spends clicking dimensions.

So the real choice is not 1Factory or High QA. It is mile-wide versus mile-deep, and whether the reading step, the part that hurts, should be done by OCR or by AI.

What switching actually feels like

The clearest way to understand the difference is to feel the friction, or the absence of it.

With the incumbents, getting started looks like this: a sales call, a demo on their schedule, a proposal to sign off on, and in the desktop-heritage cases an install and an IT conversation. You commit before you have run a single one of your own drawings through it.

With Mavlon, getting started looks like this: open a browser, upload your drawing, watch it get read in two to three minutes. No call required to see it work. No install. No seat math. You bring a drawing you already know well, and you check the output against what you would have produced by hand.

That is the test I trust most. Not a feature list, not a comparison table, not even this article. Your drawing, your eyes, the output side by side with the truth you already know. The reading either holds up or it does not, and you find out in minutes.

Bring the drawing that took someone all day

Go back to that Thursday afternoon. The crooked scan, the three sheets, the general tolerance note applied by hand, the datum frame pieced together by eye, the two hours that turned into most of a day. That drawing is the perfect demo, because you already know exactly what the right answer is.

So bring it. Bring the drawing that took someone all day. Upload it to Mavlon and watch it get read, ballooned, and turned into a filled AS9102 Form 3 in about two to three minutes, with the ten percent it is unsure about flagged for your review.

The 1factory vs high qa question assumes the choice is between two OCR tools. It is a good question, and now you have a fair answer to it. But there is a better question underneath it: whether the drawing should be detected or read. Once you have seen a drawing actually get read, the old question stops mattering. Bring the hard one and see for yourself.
