01
🎙️ Voice agent
It answers, qualifies, books the meeting or escalates. Around the clock, several calls at once.
What it returns
A missed call goes to a competitor. A human handles one call at a time, the agent takes several — the only use case here that recovers revenue rather than saving time.
Running cost
~€0.02 to €0.08 per call
The misstep to avoid
Latency kills it. Past a second of silence the caller hangs up or talks over. You must stream the answer and handle barge-in — not wait for the full sentence before speaking it.
02
🎬 Media post-production
Transcription, subtitles, clipping, formatting for publication. What an editor does, at volume.
What it returns
Dozens of hours a month out of the schedule. A freelance editor costs €380 a day; here the same output fits in a two-figure API bill.
Running cost
~€0.01 per minute of audio
The misstep to avoid
Never route the video through the phone. Upload to the server, process there, notify when ready. A job started from the app dies the moment the screen locks.
03
📄 Content engine
Articles, product sheets, document summaries, rewrites. Structured, not filler by the yard.
What it returns
A decent product sheet for each of your ten thousand references, instead of three hundred written by hand and seven thousand left empty.
Running cost
~€0.003 per generation
The misstep to avoid
Demand structured output, never free text to parse afterwards. The day the model adds a polite sentence before its answer, parsing breaks silently and you publish the sentence.
04
💬 Business assistant on your data
An assistant that answers from your documents, your catalogue and your procedures — not from the internet.
What it returns
Repetitive support questions stop reaching a human. And the internal team stops digging through eighty pages of procedure.
Running cost
~€0.002 per question
The misstep to avoid
Without automated evals you will never know it started making things up. You need a suite of trap questions replayed on every model or prompt change — that's what separates an assistant from a time bomb.
05
🎚️ Adaptive onboarding
Three questions on arrival, and the app tunes itself: screens, wording, the first action offered.
What it returns
The cheapest retention lever here. The first two minutes decide, and that's where half of installs are lost.
Running cost
negligible — rules are often enough
The misstep to avoid
Don't call a model for this. A rules tree does the same job, instantly and offline. Putting AI here adds latency and a bill to an already-solved problem.
06
🗣️ Voice that fills the form
The user speaks, the fields fill in. A site report, an order, a customer record dictated while walking.
What it returns
The use case that unlocks field work. A twelve-field form thumb-typed on a site never gets filled; dictated, it takes twenty seconds.
Running cost
~€0.004 per dictation
The misstep to avoid
Always show the filled form before submitting, and make it editable. Transcription gets numbers and proper nouns wrong — exactly what matters in a business form.
07
📸 Document reading
Receipts, invoices, purchase orders, ID papers: photographed, read, filed into the right fields.
What it returns
Manual entry disappears. The easiest use case to quantify in front of an owner: how many documents a month, how many minutes each.
Running cost
~€0.002 per page
The misstep to avoid
Handle the bad photo before anything else. Backlight, folded paper, half the receipt out of frame: if the app can't say "retake it", the user assumes it worked and finds out at accounting time.
08
🔍 Search that understands
Find by meaning and context, not exact words. "The waterproof jacket for the mountains" returns the right item even if none of those words is in its description.
What it returns
An internal search that returns nothing is a lost sale and a user who won't try again. On a catalogue it shows up directly in conversion.
Running cost
~€0.0001 per search
The misstep to avoid
Keep classic search alongside. On an exact reference or a serial number, meaning-based search is worse — you need both, and take the better of the two.
09
📝 The summary that saves the hour
A forty-page report, an hour-long meeting, a three-day thread: a one-minute note.
What it returns
The time recovered is management hours, not execution hours. That's what makes this one easy to sell internally.
Running cost
~€0.006 per document
The misstep to avoid
Always link back to the source from the summary. A note you can't verify won't be used to decide — and a summary that doesn't inform a decision is useless.
10
🔔 Re-engagement that isn't generic
Notifications written from what the person actually did in the app, not one message blasted to everyone.
What it returns
Thirty-day retention decides whether an app lives or dies. A generic nudge gets muted; a well-aimed one brings people back.
Running cost
~€0.0005 per send
The misstep to avoid
Never let a model send directly. Generate, cap the frequency, keep a banned-phrasing list, and watch opt-outs. One bad notification costs you permission to send any more — and that doesn't come back.
