CandiSift vs Ducknowl

CandiSift is an open-source applicant tracking system for parsing resumes, matching candidates to job descriptions, and ranking applicants through a bias-audit workflow. Recruiters can create roles, upload PDF, DOCX, or plain-text resumes in batches, and review ranked results with accept or reject decisions. The screening sequence strips personally identifiable information, applies hard filters, ranks candidates, then sends those who remain to persona agents and human review. Token-cosine ranking, technical and risk personas, and synthesis contribute to that process. Before confirming a staged batch, users can view estimated processing costs; deterministic filters run before the paid LLM stage. CandiSift connects to Anthropic Claude through Agno persona agents, with an offline stub LLM available when there is no API key. It can run in Docker, uses SQLite by default, and supports a Postgres database URL. The project describes HTTP Basic authentication, security headers, rate limiting, upload validation, request limits, prompt-injection defenses, and an append-only audit log. The API includes a bias-audit endpoint. The project has no shipped accuracy benchmark; OCR, embeddings/FAISS, and skillNER are described as swaps rather than included defaults. The software fee is $0.00 per free; LLM processing may incur per-token costs.

Ducknowl is a candidate screening and assessment platform for recruitment teams. Its resume parser and keyword matching organize candidate details and rank resumes against recruiter criteria; the screening page says parsing supports over 30 languages. Candidates can record one-way interview answers on their own time, while recruiters can review responses and share profiles and ratings with their team. Assessments cover programming, IT, computer literacy, accounting, language, typing and data entry. The assessment page describes real-time audio and video identity checks, restrictions on navigating away from the test screen and detailed reporting as proxy-prevention features. Recruiters can create video job descriptions. Listed integrations include Greenhouse, JazzHR, Crelate, Zoho, SmartRecruiters, Joynd, Dynamic ATS, LinkedIn, Dice, Download, Jobvite, CEIPAL and Indeed. Ducknowl says it follows SOC 2 practices, obtains applicant consent before video or technical screening, and does not share this data with third parties. It also says it supports accessible arrangements for candidates with disabilities. The platform is available on Android, iOS and the web; pricing is customized and available on request.
