You're comparing vendors in a spreadsheet. Sidrun Source reads any supplier product page, finds comparable products across other vendors and shows you spec by spec how each one matches — then carries the one you pick through to quote, PO and approval.

Stop copying specs into spreadsheets
Reads any supplier product page into clean, structured fields — name, catalog number, supplier, technical attributes, availability and datasheet links.
Finds comparable products across other vendors' catalogs and labels each one High match, Possible match or Adjacent — scored on specs, pack fit and documentation, with the reasons spelled out rather than a black-box number.
Captures every pack option and normalises to price per unit, so a 5-pack and a 250 ml bottle finally compare on the same basis.
Upload a datasheet PDF, or use the bookmarklet when a site is behind a login or blocks scrapers. Awkward sources stay in scope.
Comparison is where most tools stop — Sidrun keeps going
Finding the better option is only half the job. Pick an alternative and Sidrun hands it straight to the procurement pipeline: quote requests go out to the vendors, responses come back normalised and ranked, the purchase order gets drafted, and it routes for approval — with every step logged and timestamped.
Same workspace, no re-keying specs into a separate system. The product data pulled off the supplier page carries all the way through to the PO.
See the full pipeline in the Getting Started guide →Quote requests go out to vendors; responses are normalised and ranked side by side.
Purchase orders drafted and routed by order value and policy thresholds.
Bring your supplier catalogs — Sidrun searches them alongside the open web.
Every decision logged, timestamped and explainable. Compliance-ready.
Every way out, with the compatibility catch on each one
Discontinued PLCs, HMIs and comms modules, with the replacement routes the manufacturer will not list for you: the official successor, compatible third parties, the used market, and staying put. Price band, availability and the runtime or project-format dealbreakers sit side by side, and every claim traces back to a named source.

No card, no quota, no per-seat maths — just a sign-in to keep your extractions in one place. We're still learning what teams get the most value from, so we'd rather have your feedback than your credit card.
Paid plans may arrive later — existing users get reasonable advance notice first, as set out in our Terms.
Built for sensitive data from day one
Documents and extracted data are stored securely on our servers, never shared with third parties, and never used to train AI models. You control your data.
We do not use your documents, queries, or outputs to train or fine-tune any AI model. Ever.
Every extracted field traces back to the page it came from, with a confidence score and flags on anything unclear. No invented specs, no fabricated part numbers.
Deploy on-premise or in your private cloud. Full control over your data pipeline, with no external dependencies.
