Switching from Arphie — common questions
Is BidAuthor an Arphie alternative?
Yes — both are AI-native response tools. The differences show on platform depth: BidAuthor adds dependency-aware answering, proposal versions, inline citations against your knowledge base, published per-question pricing, and a public API.
Which handles complex, multi-part RFPs better?
BidAuthor was built for them: the extractor produces a requirement tree (including nested and conditional items), and the answering engine resolves dependencies first so downstream answers inherit upstream context.
Can I trial BidAuthor without a sales call?
Yes — the free tier lets you upload a real solicitation, extract its requirements, and generate answers end-to-end before paying anything.
Do both tools cite sources?
Both link answers to sources; BidAuthor's citations are inline per answer and point to the specific grounding passage, and they persist into review and export.
