Alfa AI vs Arbi

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

Alfa AI

Quote-based

UK-built AI recruiter that runs a role from brief to shortlist: it sources from 800M+ profiles, posts job ads to LinkedIn and Indeed, has an AI avatar called Lisa interview every applicant over audio or video, scores each one with evidence and syncs the shortlist into your ATS. Pricing is quoted after a demo, so it suits teams with enough open roles to justify a sales process.

Where Alfa AI fits

  • In-house TA teams running many roles with a small recruiting staff
  • Agencies that want overnight screening of inbound applicants
  • Teams on Bullhorn, JobDiva, Ceipal or Loxo that want sourced and screened candidates pushed in
  • UK and European employers that need GDPR, ISO 27001 and SOC 2 coverage

Arbi

$79/mo

Arbi, from Neuroscale AI, puts plain-English sourcing, criteria-based screening, email sequences and spoken AI interviews in one platform. Per-seat plans run $79, $179 and $279/mo billed annually, each with a monthly credit allowance for contact unlocks. It fits small in-house teams and agencies that want one tool in place of separate sourcing and interview products.

Where Arbi fits

  • Small in-house teams that want sourcing, screening and first-round interviews in one tool
  • Agencies screening large applicant stages against written criteria
  • Federal, defense and regulated employers that need SOC 2 and ISO 27001 reports

Where they pull apart

Alfa AI

Stands out: It covers both outbound sourcing and inbound screening in one agent, where most rivals do one or the other, and the 24/7 avatar interview means applicants are screened the night they apply. The ATS list is unusually long at more than 75 systems, covering US agency tools like Bullhorn, JobDiva, Ceipal and Loxo as well as Workday, Greenhouse and many European ATSs.

Watch out: There is no public price, no trial and no self-serve sign up, so cost is unknown until a demo. Video avatar interviews put it squarely under rules such as NYC Local Law 144 and the EU AI Act; the FAQ lists those questions without answers on the page, so ask for its bias audit before rolling it out. There is no API or MCP, and outside reviews are not yet available.

Not the right fit for

  • Buyers who need a published price or a trial before a demo
  • Teams that want to wire candidate data into their own tools through an API
  • Executive or senior searches where an avatar first interview could put candidates off

Arbi

Stands out: The Arbitrator screener shows the profile evidence behind every good, partial or poor verdict and can re-score an entire stage when criteria change. The AI interviewer runs spoken rounds with a whiteboard for system design questions and a candidate practice round. Neuroscale also lists federal and defense teams as a target, backed by SOC 2 Type II and ISO 27001.

Watch out: Contact details cost credits (2 per unlock), and Solo includes only 500 credits a month, which Neuroscale says covers about one requisition worked end to end. ATS integration is not listed on Solo or Growth and costs $100/mo extra on Business. Sourcing agents and usage analytics on Business are still marked as coming soon.

Not the right fit for

  • Solo recruiters who unlock hundreds of contacts a month on the Solo credit allowance
  • Teams on Solo or Growth that need two-way ATS sync
  • Buyers who only want a contact-data lookup tool
