Parseur and ContractParser solve different problems.
Parseur is a mature email-first document parser. The original shape is inbound email parsing — every order confirmation, every delivery notice, every lead capture form — with an established integration ecosystem and a free tier that renews monthly.
ContractParser does one thing: take a pile of contracts, extract the fields you care about, return a spreadsheet. Pay-per-page. No subscription, no credit balance, no inbox to configure. The Verified tier audits every extracted field with narrative reasoning, not a confidence number.
If your job is ongoing email parsing, Parseur is the established choice. If your job is “I have a stack of contracts and I need a spreadsheet by end of day,” ContractParser is built for that.
Parseur's heritage matters here. They've been in market since 2016, and the original product was template- and rule-based — you defined extraction rules by training the parser on a sample email, and it applied those rules to incoming messages. AI options were added later, and the current product offers a choice: “Vision AI, Text AI, or templates.” Parseur describes its AI extraction as “instruction-based rather than trained on large sample datasets,” which adapts to layout changes more easily than the template path but tells you nothing about the underlying model — no LLM vendor is named, no GPT/Claude/Gemini. OCR is not separately disclosed but is the standard pre-step for the Vision AI path on image inputs.
ContractParser runs Anthropic's Claude Sonnet 4.6 on the Quick tier and Claude Opus 4.7 on the Verified (default) tier — current-frontier reasoning models, named here and in our docs. There's no template path, no rule editor, and no OCR engine in our pipeline: every page goes through the LLM, and PDFs and images go directly to Claude's vision pathway, which reads the page itself in the same pass as the reasoning step. (Text-native formats — DOCX, RTF, HTML, TXT — are extracted with standard libraries and sent as text; nothing to OCR there either.) The Verified audit pass is a second Opus run that re-reads the extraction and returns narrative reasoning on what it flagged.
For email parsing of structured forms (order confirmations, shipping notifications), Parseur's hybrid stack works well and the price reflects it. For contracts — where reasoning across clauses and across pages is the work, and where scanned or photographed pages are common enough that OCR errors compound — the right thing reading the document is a vision-capable frontier reasoning model, and you should know which one.
Both price per page, but with very different commitment structures.
Parseur: monthly subscription with volume-based tiers. One credit = one page; an email or spreadsheet counts as one credit each regardless of length, while a three-page PDF costs three credits. Unused credits expire at the end of the billing period. Free tier is 20 pages/month, renewable. Paid plans use a volume slider with quote-on-sign-up pricing — Parseur stopped publishing fixed monthly dollar amounts in 2026. The tier names are Base (up to 3,000 pages/month), Scale (up to 1 million), and Enterprise (up to 10 million, custom). Annual billing earns three months free.
ContractParser: pay per page. $0.15/page Verified (default, includes the audit pass), $0.10/page Quick for bulk runs. No subscription. No monthly commitment. No expiring credits. $2.00 minimum per batch.
Parseur's free tier (20 pages/month, no card) is genuinely useful for small steady volume. If you process 15-20 documents a month, you never pay a cent.
Subscriptions are a bad fit for one-time or irregular workloads. Process a 250-contract backlog over a weekend, then nothing for two months — and you've paid for three months of a paid plan whose credits evaporated unused.
Quick math: 250 pages once, then three months of silence. Parseur's free tier covers only 20 pages/month, so 250 pages overflows it on the first run — you'd need a paid plan, and any monthly plan would keep billing through the silent months.
| Approach | What you pay over 3 months of irregular usage |
|---|---|
| Parseur paid plan (any monthly tier) | 3× whatever Parseur quotes you, regardless of whether you process 250 pages or 0 |
| ContractParser Quick (250 pages × $0.10) | $25 once; nothing in the silent months |
| ContractParser Verified (250 pages × $0.15) | $37.50 once; nothing in the silent months |
The math reverses at high steady volume. A team parsing thousands of pages a month every month lands on Parseur's higher-volume tiers at a lower per-page cost than ContractParser. Pick the model that matches the usage.
Parseur is inbox-first. You get a dedicated address like your-name@in.parseur.com, forward or BCC documents to it, and Parseur extracts on receipt. Manual upload works, but the primary shape is continuous ingestion. Unlimited mailboxes on all plans mean you can run many parallel parsers for different document types.
ContractParser is batch-first. Drag-drop a folder or a ZIP (up to 1,000 documents per batch), pick fields from a checklist or write a custom prompt, download a CSV. No inbox to configure, no mailbox to remember, no workflow to maintain. Built for someone with a pile right now.
These are different product shapes. Parseur is a workflow engine. ContractParser is a batch tool.
Both use modern AI extraction with strong accuracy on well-formatted documents. The difference is how each handles uncertainty.
Parseur's output is structured data — fields and values ready to ship downstream. It doesn't flag uncertain fields or re-check its own work.
ContractParser's Verified tier ($0.15/page, the default) runs a second AI pass after the initial extraction. The second pass audits every field, catches contradictions between fields (a total that doesn't match unit price × quantity, dates that fall outside the contract period, renewal terms that conflict with termination terms), and returns narrative reasoning explaining what it flagged.
A Verified flag looks like this:
totalValue calculation appears confused — mixes per-site, per-year, and portfolio figures inconsistently; $4,752/site/year × 4 sites × 10 years = $190,080, not $220,777.52.
For high-volume routine workflows, this audit is overkill. For contract review where a single wrong number matters, it's the point.
Parseur wins here. Zapier, Make, Google Sheets, Airtable, native webhooks, and thousands of downstream apps. Custom Python post-processing is available on higher tiers. Public REST API is included.
ContractParser currently imports directly from Salesforce (pick contracts attached to your Salesforce records) and exports CSV. Google Drive, OneDrive, Box, and Dropbox imports are planned. No public API at launch — on the roadmap.
If you're wiring document parsing into a larger automated system, Parseur has more connectivity available today.
Parseur has been in market since 2016 and runs a legitimate product for a specific job: automated email and document parsing at scale. We're not trying to replace them for that use case — they're good at it.
We built ContractParser for a different buyer: someone with a pile of varied contracts who wants answers now, without configuring an inbox or paying a subscription to get through the backlog.
