  live probes of every paperplane.ai host on 2026-08-13, plus
  https://www.ycombinator.com/companies/paperplane and the Internet Archive CDX
  index for paperplane.ai
note: >-
  Paperplane publishes no versioning policy, no deprecation policy, no SLA and
  no status page — there is nothing to search for, because there is no API. What
  this artifact records instead is the operational state of the company's own
  surfaces, which is the single most load-bearing fact about this profile:
  every Paperplane-operated host except the documentation site and the identity
  instance is off. No StatusPage or Deprecation pointer is emitted, because
  Paperplane published neither; these are OUR probe findings, not the
  provider's declarations.

evidence:
- observation: Y Combinator lists Paperplane (W23) as Inactive on its own company directory page.
  url: https://www.ycombinator.com/companies/paperplane
  status: 200
  detail: >-
    The page also now describes the company as a "Credit risk management
    platform for builders' merchants", a different product from the
    sales-notes-to-Salesforce tool the documentation site describes — so the
    company pivoted at least once before going inactive.
- observation: Application host is disabled for non-payment.
  url: https://app.paperplane.ai/
  status: 402
  detail: 'Vercel, header x-vercel-error: DEPLOYMENT_DISABLED, body "Payment required".'
- observation: API host is an orphaned ingress with no routes.
  url: https://api.paperplane.ai/
  status: 404
  detail: >-
    server: envoy, content-length 0 on every path probed (/, /graphql, /api,
    /health, /v1, /openapi.json, /swagger.json, /docs, /mcp). The site root
    intermittently returns 503 "upstream connect error or disconnect/reset
    before headers. reset reason: connection failure", i.e. the ingress is up
    and the backend behind it is gone.
- observation: Marketing site presents no TLS certificate.
  url: https://www.paperplane.ai/
  status: 000
  detail: >-
    CNAME to proxy-ssl.webflow.com; the handshake fails with
    SSLV3_ALERT_HANDSHAKE_FAILURE (apex fails with tlsv1 alert internal error)
    against both LibreSSL and OpenSSL. Plain HTTP 301s to the HTTPS URL that
    cannot be completed. Consistent with a Webflow site that has been
    unpublished or whose custom-domain certificate was never renewed.
- observation: Internet Archive holds no capture of www.paperplane.ai after early 2025.
  url: https://web.archive.org/cdx/search/cdx?url=paperplane.ai&matchType=domain&filter=statuscode:200&from=2025
  status: 200
  detail: >-
    Last 200 captures of the marketing site are 2025-01-13, 2025-02-03 and
    2025-03-10; accounts.paperplane.ai and clerk.paperplane.ai were captured in
    early 2025 and docs.paperplane.ai in April 2025. Nothing in 2026.
- observation: Documentation site is a never-completed GitBook starter template.
  url: https://docs.paperplane.ai/
  status: 200
  detail: >-
    Pages still carry GitBook's own placeholder copy ("GitBook tip: your product
    docs aren't just a reference of all your features!"), sample overviews
    lifted from the Loom and Mailchimp docs, "Awesome Feature One/Two/Three",
    and lorem ipsum under a "GitHub Integrations" heading on the For Developers
    page. Several pages (Gong, Sync to Salesforce, Opportunities, Calls, Notes)
    are an H1 and nothing else. Footer reads "Last updated 3 years ago".
