The new hire
Six months of shadowing compressed: a first-year applications engineer answers a legacy-product question with the page citation, instead of interrupting the one veteran who remembers the 2014 revision.
Lifecycle / Use cases
One cited expert across the whole customer lifecycle
An instrument lives with a customer for a decade, and the pre-sales, application-engineering and support questions all trace back to the same PDFs. Practicl answers every one of them from those source documents, cited to the page — from first evaluation to year-four operation, with no handoffs between teams.
01 / Pre-sale · week 0
Pre-sales support that doesn’t wait for a call back
An engineer shortlisting laser sources has three tabs open — yours and two competitors’. The one that answers the derating question at 11 pm wins the shortlist.
Practicl answers the spec questions your datasheet already covers, keeping each value’s conditions attached, and flags your sales team when an evaluator’s questions turn serious — a warm lead, surfaced from the questions themselves.
02 / Sale · month 3
Application-engineering answers from every app note
The unit is on the bench. Now the questions are about fiber coupling budgets, mounting tolerances, command sets — scattered across app notes and manuals your customer never downloaded.
Practicl searches the whole document set at once, answers from the source only, and cites the exact page in whichever document the fact lives in — the same corpus that handled pre-sales, no new tool to learn.
03 / Post-sale · year 4
Year four, new technician, old instrument
The engineer who bought the unit left. The new technician sees E-303 after a firmware update and has never opened the manual. This is where post-sale support tickets — and reputations — are made.
Practicl has read every revision and every release note, and won’t guess past what they say. It answers with the exact firmware diff and the recalibration step, cited to the page — not a shrug.
04 / For your team
The same engine, pointed inward
Your own people carry the same burden as your customers: twenty years of product knowledge spread across hundreds of PDFs and three veterans’ heads. Point Practicl at all of it, internally.
every person on your team answers like a ten-year veteran — because the veteran’s sources are one question away.
Where we’re headed
The same capability extends to any complex hardware that ships with a manual. We’re building it where the bar is highest first.
