Documentation AI for photonics, semiconductor & precision instruments
Ask the datasheet|
Practicl turns the datasheets and manuals you already publish into an expert your customers can ask directly, in plain language. Every answer points to the page it came from — and when the document doesn’t say so, neither does Practicl.
±0.1 nm — after a 30-minute warm-up. Above 40 °C ambient, derate by 0.02 nm/°C. Cold-start drift can reach ±0.4 nm in the first 10 minutes.

01 / The problem
The answer is on page 34. Nobody reads page 34.
Your documentation is complete, accurate, and unread. Customers stop at the spec table, then email support with questions the datasheet already answers — warm-up behaviour, derating, coupling losses, error codes.
The application engineer who could answer from memory closed the deal three years ago. The PDF can’t answer back. Every unanswered question is a slower sale, a support ticket, or a customer guessing at a number they should never guess.

02 / How it works
Upload your documents. Get an expert that cites its sources.
01
Upload what you already publish
Datasheets, manuals, application notes, firmware release notes. No rewriting, no restructuring, no tagging — the documents you ship today are the source.
02
Practicl reads the whole document
Not a blind text split. It reads spec tables, footnotes, derating curves and revision histories as one document — keeping tables and procedures intact and each fact’s address (document, revision, page) attached, so every answer can point home.
03
Customers ask. It answers, cited.
Answers carry the condition with the number — the warm-up behind the stability spec, the ambient limit behind the derating — and are checked against the source before they ship.
04
It gets better at your product
This is the step a general-purpose AI tool cannot do. Practicl builds up a picture of your specific product line — which specs get misread, which questions your documents cannot answer, which accessory the customer actually needed — so your engineers stop answering the same question twice and your next revision writes itself.
Real questions, three industries
If your customers ask questions like these, Practicl is for you
Photonics
“What wavelength stability holds across 25–40 °C?”
±0.1 nm after a 30-min warm-up.
↳ datasheet · p.34
Semiconductor
“What chamber pressure does this etch recipe qualify at?”
8–12 mTorr, with the throttle valve in closed loop.
↳ process manual · p.112
Precision instruments
“How often does this stage need recalibration?”
Every 12 months, or after any hard stop collision.
↳ service guide · p.7
03 / Lifecycle
It stays with the customer after the sale
Most tools stop at the purchase order. Practicl keeps answering — week 0, month 3, year 4 — long after the sales engineer who closed the deal has moved on. Each customer can get their own private link to the exact documents they bought.
week 0
01 / Pre-sale
“Can it hold ±0.1 nm across 25–40 °C?”
Yes — ±0.1 nm after a 30-min warm-up.
↳ datasheet · p.34
month 3
02 / Sale
“What coupling loss should I budget for FC/APC?”
0.8 dB typ, 1.2 dB max into single-mode fiber.
↳ app note AN-107 · p.5
year 4
03 / Post-sale
“E-303 started after the 2.4 firmware — what changed?”
2.4 tightened the TEC fault window; recalibrate to clear.
↳ release notes 2.4 · p.3
Same source documents. Same citations. No handoffs. One link per customer.
04 / The principle
When the document doesn’t say, Practicl says so
A wrong answer about a laser isn’t a bad user experience — it’s a damaged instrument and a lost customer. So Practicl answers only from your documents, preserves every value exactly, and validates each answer against the source before it ships.
If the source doesn’t cover it, it declines and routes the question to your applications team — which also tells you exactly where your documentation has a gap.

Question
Can I operate the SL-940 at 55 °C ambient?
Answer
The documentation specifies operation up to 40 °C ambient. Behaviour at 55 °C isn’t characterised in any published document — I won’t extrapolate.
∅ not in the source→ routed to your applications team
05 / The intelligence layeron the roadmap
You won’t have to guess what your customer needs
Every question shows where your documentation helped and where it fell short. We’re building Practicl to aggregate them — anonymised, never individual profiles — into a short, practical list: what to clarify, what to write next, and what your customers genuinely need from you.
This is what we’re building next, not what ships today. Answers, citations and the refusal behaviour above are live now.
What confuses them
warm-up drift · 34 asks this quarter
Where the spec is real but the datasheet buries the warm-up condition in a footnote — so you know to move it.
Where the docs fail
12 questions · no answer in source
Every declined answer is a documented gap. The plan is to give you that list, ranked by how often it’s asked — a work queue for your next revision.
What they need next
integration-grade questions · rising
When questions move from “what are the specs?” to fiber coupling budgets and mounting tolerances, a real integration is underway — the moment to offer the mount, the app note or the calibration service that genuinely helps.

We set the bar where documentation is hardest: 50–500 person photonics and precision-instrument companies. What clears that bar travels — complex hardware elsewhere comes later.
