Office software has been getting heavier for years, and most of that weight is AI features nobody asked for, bolted onto apps that worked fine without them. A new open source office suite has decided to make AI the entire point. I spent some time digging into what is real, what is hype, and what a writer or a small team admin should actually check before making it their daily driver. This piece is a checklist, not a review. The product changes fast, and the questions you need answered will outlast whatever version you test today.
What “AI first” actually means in a desktop office app
Most office apps treat AI as an add-on. There is a sidebar, a chat window, a button that says “ask the assistant,” and you can ignore the whole thing if you want. An AI first app inverts that. AI is not a feature you toggle. It is the editing model. You do not type into a sidebar, you ask the editor to do work and the change happens in place. The difference sounds small on paper. It is the difference between a tool that helps you write and a tool that writes for you.
The interesting design question is not whether AI is good or bad. It is who pays for it and how. A self hosted model on your laptop would be the obvious answer, and almost no app does it that way. The pattern in this corner of the market is a hosted model behind a credit system, billed per prompt or per month. That choice determines almost every other thing you need to know about the product, starting with privacy.
The privacy plumbing you have to trace
If you cannot run the AI on your own hardware, every prompt you send leaves your machine. The question worth asking is not whether the app respects your privacy. The question is what happens to the text after you hit send, and which companies see it before a response comes back.
There are three pieces of plumbing to trace. First, who hosts the model. Second, whether the app sends your text to that host directly, or relays through an intermediary. Third, whether the host in turn calls one or more third party model providers under the hood. The last piece is the one most users miss, and it is the one that determines who actually reads your text.
The general pattern across AI first office apps in 2026 is: open source desktop shell, closed hosted model, third party providers under the model host. That combination is fine for a draft blog post. It is not fine for a draft contract, a customer email, or anything with personally identifiable information. The cleanest rule of thumb is the same one you would use for any cloud service: do not paste anything into an AI prompt that you would not put in an email to a stranger.
A few specific moves worth making when you evaluate a new tool:
- Read the model’s terms of service, not just the app’s. The app may have a privacy page that delegates everything to the model host.
- Look for a “self host” or “bring your own key” option. If it is not there, plan for your text to leave the device on every AI call.
- Try one sensitive workflow first. If the prompt round trip is fast and the output is good, you still do not know where the text went. Test by sending a canary string and grepping your logs later, if you have the skills.
- Ask the maintainer directly, on a public channel, where model calls go. Silence or vague marketing speak is itself an answer.
Platform support is a tell
The single most useful signal about an AI first app is which platforms it ships for. A desktop app that only ships for Windows and Apple Silicon tells you two things. First, the developer has finite time and chose to support the platforms that matter for the use case they imagined. Second, if you are not on those platforms, you are explicitly outside the imagined use case.
For a writer or a small team admin, the relevant question is whether the platform you actually run is in the supported list, and whether there is a public timeline for your platform if it is not. If you run Linux, and the answer is “no build yet, watch the repo,” that is a real answer. It means the product is not for you today, and there is no commitment that it will be tomorrow.
If you are on a supported platform, platform support still tells you something. An app that ships for one chip family per OS is more likely to be optimized for that family than an app that ships for five. The narrower the matrix, the more time the developer has spent on the user they targeted.
What to actually test before you commit
If you want to test an AI first office app without committing, here is the order I would use, and what each step is supposed to tell you.
First, pick a real document you do not care about and try a rewrite. A draft blog post works well. Watch where the AI lands the change. If the rewrite happens in place, good. If it happens in a sidebar and you have to copy back, the app is not actually AI first, it is AI bolted on, and the rest of the questions change.
Second, open a spreadsheet you actually use and try a few formula or layout tasks. The quality of the non AI work is the floor. If the spreadsheet engine chokes on your real data, the AI features will not save the product.
Third, test the slide generator if there is one. Try a small deck, three to five slides, and see how much editing the AI output needs before it is presentable. A slide generator that produces a presentable first draft is a productivity win. A slide generator that produces a draft you would be embarrassed to send is a curiosity.
Fourth, read the model’s privacy policy before you paste anything sensitive. The local editing is fine, the AI calls are not. If you cannot find a clear answer on where the text goes, the answer is “somewhere we will not tell you,” and that is enough to keep sensitive workflows off the product until you have one.
The two questions that determine whether to switch
If a product clears the four tests above, you are left with two questions, and they are the only ones that matter for a switch decision.
The first is cost. An AI first app that bills per prompt will be cheap for a writer who uses it twice a week and expensive for a writer who uses it twice an hour. Estimate your actual prompt volume, multiply by the per prompt cost, and compare to a subscription you already pay for the same kind of work. If the AI first app is cheaper at your real volume, switching is worth a real trial.
The second is lock in. An app that exports to the standard formats you already use (a real word processor format, a real spreadsheet format, a real slide format) is easy to leave. An app that exports to a proprietary format or that requires its own runtime to render old files is a commitment. If you cannot open the file you made today in five years without the app, the AI features are not the only thing you are signing up for.
On the honest answer to both questions is “it depends on your volume and your format choices.” The dishonest answer, which is the one most review sites will give you, is “this app is great.” Run the four tests, answer the two questions, and decide for yourself.
Trade-offs
The big trade off is privacy versus capability. A self hosted open source model is the cleanest answer, and almost no AI first app ships that way because the hardware cost is too high. Until that changes, every AI first desktop app is a tradeoff between what the model can do and where your text goes. The smaller trade off is platform support: an app that targets Windows and Apple Silicon is a great fit for someone on those platforms and a non starter for everyone else.
A narrower trade off worth naming: an AI first app built by a single developer in a few months is fast and opinionated, but it will also pivot fast when the underlying model host changes pricing or terms. The product you test today may not be the product you use next quarter. That volatility is the cost of betting on a small project, and it is part of why I would not bet a business on any AI first desktop app that does not have a clear answer on model hosting.
What I would actually do this week
If you write for a living, run the four tests above on a draft you do not care about, and decide whether the rewrite quality is worth the prompt cost at your real volume. If you handle sensitive text, keep it on a local app you trust until the AI first vendors ship self hosted or bring your own key options. If you run Linux, watch the project’s issue tracker for a build, and do not change your daily driver based on a roadmap promise.
