Where AI Saves Real Time in an Office Day

Krisztian Eyssen, Krisztian Eyssen

Where AI Saves Real Time in an Office Day

Seven task types, with measurements. In some the saving is large and real: in a 444-person experiment a writing task fell from 27 minutes to 17. In some it is exactly zero: in a 6,000-person experiment measured by telemetry, time spent in meetings did not move. And in some the machine slows you down. The difference is not luck, it is the type of task.

Meeting Notes People Actually Read

Meeting Notes People Actually Read

A good set of meeting notes is not a summary, it is three lists: decision, owner, deadline. Nobody reads whatever else is in there. The machine can write all three — but in the most recent measurement **more than 40% of the claims in generated summaries were not supported by the recording**, and outside the big languages even the transcript gets every seventh word wrong.

Inbox Triage with AI

Inbox Triage with AI

The inbox is the place where AI measurably helps — but not the way you expect. In a randomised 6,000-person experiment, the people who actually used it spent **18% less time** reading email, while the number of conversations **did not change**. And there is one risk that barely gets discussed: an incoming message is not only data to the machine, it **can also be an instruction**.

Spreadsheets and Data Cleanup with AI

Spreadsheets and Data Cleanup with AI

The spreadsheet is the ground on which AI is wrong with the most confidence. In the most recent measurement, run on real business workflows, the best model reached **34.9% task accuracy** — and on debugging, **12%**, which makes it least suited to precisely what most people would use it for. Its mistakes are also quiet: what comes back is not an error message but a plausible number.

From Outline to Deck: Slides with AI

From Outline to Deck: Slides with AI

The expectation is that the structure is your job and the machine takes care of the design. The only independent measurement says **it works the other way round**: on the logical build of a deck the best system scores 81 points, but **on visual layout even the best manages only 62.8**, with most of the field under 50. And source fidelity is worse still.

Drafting Contracts, Offers and Reports with AI

Drafting Contracts, Offers and Reports with AI

There are two measurements, and at first glance they rule each other out. On drafting contracts, AI performed **on a par with human lawyers** — 57% versus 56.7% reliability, and in under a minute instead of thirteen. On legal research, though, even the market-leading specialist tools **hallucinated in 17–33% of cases**. The two are not a contradiction: writing a draft and finding a citation are not the same job.

Project and Task Management with AI

Project and Task Management with AI

For this area **there is no controlled-group measurement** — and that is worth saying out loud before anyone quotes a number at you. What there is: task-level data from two government rollouts, one set of which its own publisher calls an **upper estimate**; a finding that 60% of participants had to edit the output substantially; and up to 7% for whom the work **grew** because of it.

Automating Recurring Reports

Automating Recurring Reports

On a 2026 benchmark for data-analysis agents, the best system answered correctly first time in **38%** of cases — and, worse than that, one model returned **a silently empty answer in 63.4%** of cases when it got stuck. Not an error message. An empty result. On a monthly report that is the most expensive kind of failure, because it stays hidden for months.

Transcription and Subtitles: A Working Pipeline

Vendors advertise error rates around five percent. Independent measurements on real, spontaneous speech come out several times higher. Both are true — and the difference is exactly why the transcript has to be reviewed.

Email Drafting That Still Sounds Like You

Email Drafting That Still Sounds Like You

Email is the genre where machine assistance measurably works best — and where style imitation is most accurate. Three inputs, a prompt you can copy, and the five things that give it away anyway.

Reliable Summaries of Meetings, Reports and Threads

Reliable Summaries of Meetings, Reports and Threads

With summaries the main risk is not invention but omission — and the omitted part is usually in the middle. Four failure types, a prompt that punishes omission, and a two-minute check.

AI Is a First-Draft Machine, Not a Writer

Measured drafting time falls by a third to a half. Time to a finished document does not. That gap is what this post is about: where the machine's job ends and where yours begins.
