Free lesson, before the pitch

Learn it first: how to check any software yourself, in five questions, before you trust it with client data.

Software is a promise about where your work lives and who else can touch it. Ask every company these five, and write down the answers: 1. Where does my data live? 2. What happens if you close, or double the price? 3. Can I get my data out in a standard file? 4. Who built it, and do they do my job? 5. What does it depend on, and will you show me the list?

Made-up example. A made-up clinic owner asked two vendors. The first said “our secure cloud,” “you can request an export,” and had no list. The second said “on your computer,” “it is already in Excel,” and handed over a page like this one. She did not need to be technical to see the difference.

Try it: a made-up app keeps notes on its own servers, exports only to its own file type, and lists nothing it depends on. Which questions does it fail? — show the answer, and why

Three for certain: 1, 3 and 5. Your data lives on someone else’s computer, you cannot open it without them, and you cannot judge what might break it. Questions 2 and 4 you would still have to ask. This is Chase’s own buying checklist, not a published standard.

Thank you. DRAGEN stands on the work of thousands of people who built these tools, most of them free and open to anyone. Every link goes to the maker. None are ads or affiliate links, and none of these companies sponsor DRAGEN.

44 of the 58 are free, or free with Windows, or have a free plan. The package itself needs nothing you pay anyone else for, beyond the Windows and Office most offices already have. Every card says which is which.

The other 14, and who pays. Chase pays for the tools that build and sell DRAGEN, now and later. You never need them.

SoftwareWho paysWill you ever need it?
Windows 10 or 11You, and it came with your PCYes. DRAGEN runs on Windows. A new PC comes with it.

  • DRAGEN: the price you choose on the Pricing page, once or monthly. Updates are optional, at 20% of the licence a year.
  • Required, and already yours: Windows, and the internet and email you already have.
  • Only if you choose: Microsoft 365 for Word and PDF reports, your own Claude or Codex key, the G2 glasses and R1 ring.
  • Never yours: every tool Chase uses to build and sell DRAGEN. Those costs are his.

Local AI: the AI that lives on your computer.

It drafts and sorts right on your PC. Client words never leave it. Ollama keeps itself up to date in the background. DRAGEN reads your memory and your graphics card during setup and installs the strongest model your computer can run. Nothing to choose. Click DRAGENmodel any time you add memory or a card, and it moves up a tier.

Examples

What different computers can run.

A bigger model writes better drafts, but it needs more memory. Here is what each kind of computer can run on its own, with no cloud.

Section 3 · the five questions, answered

Why it matters.

Most software is rented from someone else’s computer. That is fine for a playlist. For a child’s records, ask the five questions. Here is how a typical cloud tool usually answers, and how DRAGEN does.

The questionTypical cloud softwareDRAGEN
Where does my data live?On the company’s servers.On your own computer.
What if the company closes, or doubles the price?You can lose access, or pay the new price.Own it once. It keeps running on your PC.
Can I get my data out?Through an export the company controls.It is already in Excel, Word and plain files.
Who built it?Usually engineers, advised by clinicians.A practicing BCBA, who uses it in his own work.
What does it depend on?Rarely listed.Every piece, named on this page.
Does an outside AI read client words?Many AI tools send your text to an AI company.Never. Client words stay with the local AI.

“Typical” means the usual way cloud software works, not any one company. Ask your own vendor; the good ones will answer plainly.

Built on the bliss point of AI

If they die, DRAGEN keeps flying.

AI is the best and cheapest it has ever been, and that may not last. DRAGEN was built with the strongest AI of this moment, then made to run without any of it.

1

Your copy is yours

Own it once and it runs on your PC. No outside company can switch it off.

2

The AI is a file on your disk

If every AI company changed its prices tomorrow, your local model would not notice.

3

Claude and Codex are optional

Built with them, runs without them. Even if they were banned by law, DRAGENsoftwares still work.

4

Plain files, readable forever

Word, Excel and plain-text settings. Any computer opens them, with or without DRAGEN.

5

Every piece is named

Nothing hidden: if a part ever needs replacing, everyone can see which one.

6
