Eustace vs Stipple

Eustace is a web-based fact-checking workspace for writers and researchers working with AI-assisted drafts. Users can paste text or import a URL, PDF, or Word file; scanned PDFs are processed with OCR. The service extracts candidate factual claims and displays their original quotes so users can select which to verify. Approved claims are checked against fresh web sources rather than the submitted document. Its ledger uses ten verdicts and three confidence levels, and the product says it signals uncertainty when evidence is thin or mixed. Users can inspect sources, attach private evidence, override a verdict with the change recorded, and export a Markdown report with claims, verdicts, confidence, and citations. Eustace says it does not sell user data or use documents to train AI models. The Free plan provides 25 lifetime verifications; Pro costs $19/month for 500 each month, with optional $0.05-per-claim overage turned off by default. Automated verdicts, confidence labels, and summaries can be wrong, incomplete, or out of date, so they are intended to support rather than replace editorial judgment.

Stipple helps suppliers find Australian and New Zealand tenders and prepare bid responses using company evidence they already have. Suppliers can enter a company website to rank open opportunities by fit, with reasons and gaps shown alongside each match. Stipple notes that a fit score is not a probability of winning. Its search registry covers AusTender, GrantConnect, NZ GETS, state and territory portals, VendorPanel, and council, university, and health buyers. For response preparation, Stipple organizes tender requirements with source-page references, matches them to supplier documents, and drafts responses for review and editing. A person reviews each line before a draft is sent, and Stipple does not send responses to buyers. The service offers a REST API and hosted MCP server, plus document tools including text detection, citation checking, field extraction, identity checks, and PII redaction. Free document checking allows 20 checks weekly without an account or 100 with one. The free tender search and matching plan is free; response preparation has no listed price and is agreed before work starts.
