Finding parts is free. Answers cost cents.
A datasheet answer is 2¢ and an AI check 5¢. Every plan includes a month of usage, and Free needs no card.

Prices are in US dollars. Paystack charges your card in South African rand at the day’s exchange rate, and 15% VAT is added for South African billing addresses. Your own datasheets cost 10¢ each to upload, with no storage fee.
Per-call prices
All 14 tools, in three price levels and an upload fee. Your agent picks the tool; the list price is the same on every plan, and a plan’s included usage is spent first. A call that fails validation, such as an upload that isn’t a readable PDF, isn’t charged.
Finding parts, Free
Searching distributors, a part's details, and getting datasheets ready to read.
- search_partsFinds parts by number or keyword across JLCPCB, Mouser and DigiKey, with stock and price from each.Free
- check_extraction_statusReports how far a datasheet that is still being read has got.Free
- request_datasheet_uploadGives your agent a private link to upload a PDF we couldn't find, or one of your own.Free
- find_partsFinds parts that meet numeric specs, such as voltage, current and package.Free
- prefetch_datasheetsStarts reading up to 20 datasheets at once, so a whole BOM is ready before you ask about it.Free
- get_part_detailsReturns a part's key parameters, package and datasheet status.Free
Datasheet answers, 2¢
Sections of a datasheet, searches inside them, comparisons, substitutes and BOM checks.
- search_datasheetsSearches every datasheet we have read by meaning, such as “LDO with PSRR above 70 dB”.2¢ per call
- check_bomChecks up to 50 BOM lines for lifecycle, stock against quantity and sourcing.2¢ per call
- find_alternativeSuggests drop-in and functional substitutes for a part.2¢ per call
- compare_partsLines up two or more parts side by side on the specs that differ.2¢ per call
- read_datasheetReturns any section of a datasheet as text and tables, or searches within one datasheet.2¢ per call
AI checks, 5¢
A model judges your operating conditions against the ratings, or reads values off a figure.
- analyze_imageReads values off a datasheet figure: a graph, a package drawing or a pin diagram.5¢ per call
- check_design_fitChecks your operating conditions against the part's absolute maximum and recommended ratings.5¢ per call
Your own datasheets, 10¢
Adding a PDF to your organisation's private library.
- confirm_datasheet_uploadChecks an uploaded PDF, reads it and adds it to your organisation's private library.10¢ per call
There is no monthly fee for keeping private parts.

Estimate a month
A rough figure from your team size and how often you ask. Each kind of question is priced as the few calls an agent usually makes for it, at the rates above, without VAT.
$0a month on Free
About $1.32 of usage: 2¢ a question, 9 calls a day
Free fits best. It fits in the $2 of usage Free includes every month.
Questions
- Does Free really refill every month?
- Yes. Every Free account gets $2 of usage each calendar month, with no card. It is never taken back, and what you don’t use doesn’t carry over.
- What happens when Free's $2 runs out?
- Datasheet answers and AI checks stop until the next month, and your agent gets a link to upgrade. Finding parts keeps working. Nothing is ever charged to a card on Free.
- How does Pro's $20 work?
- It is all usage: the first $20 of calls each month are included. Past that you pay the list prices above, up to a monthly spend cap you set, so a busy month never surprises you.
- What does Team add?
- $60 of usage a month, pooled across up to 10 people, a private part library the whole team shares, and monthly invoices with VAT.
- What counts as a new datasheet?
- The first time anyone asks about a part we haven’t read yet, we fetch and read its datasheet. After that it’s cached for everyone, and reading it again doesn’t count toward Free’s 10 new datasheets a day.
