Arbi vs Pin

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

Starting price

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

Pin

$100/mo Free tier Free trial

Suits recruiter desks that want an agent to source and send first-touch on open reqs. Pin sits beside your ATS, not in it. Paid plans start at $100/mo for one Solo seat, billed annually.

Where Pin fits

  • In-house TA running several open reqs
  • Agencies that want agent loops per client
  • Desks that already have an ATS of record
  • Teams connecting Claude or ChatGPT via MCP

Where they pull apart

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

Pin

Stands out: Hosted MCP plus an agent that sources and sequences against the req.

Watch out: ATS export is an add-on, not part of the base seat.

Not the right fit for

  • Teams that need Pin to be the ATS
  • Buyers who only want a contact finder
