Explore the live demoThe inbox
Built for the person who actually answers the emails.
Buyers and AP live inside the thread: order confirmations, price changes, freight bills, the invoice that almost matches. Kynthar reads the same mail and turns it into a working list — what changed, what conflicts, what needs an answer today — with every claim traced back to the document that said it. The overcharges are what you show your manager. The clear inbox is why you come back tomorrow.
Most spend tools make you book a demo. Kynthar opens with your own inbox.
The structure
Track everything. Miss nothing.
Kynthar tracks every PO, shipment, contract, vendor, and item across your procurement operation. It reads every email and document that flows in, connects them, and tells your team what to act on before money moves.
Every purchase order
Acks, change orders, and receipts land on the PO's timeline as they arrive. Status without chasing anyone.
Every promise date
A vendor's acknowledgment revises the ship date? Tracked as a delta, with the email that moved it as the source.
Every price
Per item, per vendor, over time. A price-increase email is flagged against your open orders the day it lands, then checked against the next invoice that cites it.
Every contract term
Invoices are checked against the clause that governs them: ceilings, payment terms, escalators.
Every vendor identity
A banking-change email gets flagged before money moves. The classic wire-fraud setup, caught on arrival.
Every shipment
ASN to bill of lading to proof of delivery, quantities reconciled across the chain.
One mechanic underneath: forward the email, and the story updates itself. 100+ checks run continuously as documents arrive.
Security
Built for a team that answers to legal and finance.
- You choose what to send. One pair is enough to start. Redacted copies work.
- Your documents are used to produce your receipt and nothing else.
- We never contact your vendors.
- No ERP connection, no IT ticket, no integration: a pair check is one email.
Your data, your tenant
Row-level security on every query; isolation enforced at the database layer, server-side.
Encrypted in flight and at rest
TLS 1.2+ on every connection; AES-256 at rest.
Hashed, scoped API credentials
SHA-256 hashed at rest, scoped to one company, rotatable without downtime.
Never used to train AI models
Kynthar never trains models on your data. Our LLM providers process it only to serve our requests, under enterprise API terms that prohibit training on customer data.
Delete everything on request
Documents, extractions, and audit trail permanently deleted within 30 days of request.
Every access logged
Auth events, API calls, and data access logged with 365-day retention.

The path
Where this goes.
- 01One pairA verdict with a receipt.
- 02One vendor, one quarterA mini-audit with a dollar total.
- 03Twelve monthsThe full retrospective audit.
- 04ContinuousEvery invoice checked before it's paid. Implementation = forward an email.
Each step is earned by the one before it. You never share more than the last result justified. When you’re ready for more: self-serve Team is $1,250/month and annual Platform contracts are sized to your volume. Details on the pricing page.
FAQ
Five questions, honest answers.
What happens to my data?
Your documents are used to produce your receipt and nothing else. They live in your own isolated tenant, are never used to train models, and are deleted on request.
How fast does it work?
The system resolves most pairs in minutes. The promise we print is the one we can always keep on the worst realistic input: your verdict lands within one business day.
Can we cancel anytime?
Yes. The Pilot is free, with no card on file, so there is nothing to cancel until you choose a plan. Team is $1,250/month, self-serve, cancel anytime; Platform is an annual contract. Terms are on the pricing page.
What if it gets something wrong?
Every finding carries its receipt (the source line, the clause, and the math), so a wrong finding is checkable, not arguable. Withdrawn findings are tracked, and you never act on a number you can't trace to its source line. We'd rather print no withdrawal rate than one too thin to trust.
Do we need IT involved to start?
No. A pair check is one forwarded email. IT enters only if and when you connect systems at later rungs.
Your inbox already holds the answer.

From the founder
Kynthar is built and run by Josh Spadaro, built after watching procurement teams at multiple manufacturers drown in volume. If you’d rather talk to a person before forwarding anything: jspadaro@kynthar.com, or grab time directly for a guided demo.
