MemHub + API
Features7
  • Autonomous discovery — a deep-research-style pass that decomposes a question, fills gaps, and ingests what it finds directly into a brain.
  • A 14-day in-app trial for company orgs, with no card required.
  • Referral codes are captured at signup.
  • Documents in a brain are searched as part of chat retrieval.
  • More document types accepted on upload.
  • MCP server — inbound MCP server with read-only search_memory.
  • MCP serversave_artifact and add_memory write tools, plus a Claude Code turn-save hook.
Improvements4
  • Slack binding status is readable, so the UI can tell whether Slack is actually connected.
  • Billing — checkout returns amount_total and currency, and has_billing_account is exposed for the trial-to-paid upgrade path.
  • Scoped data access to support the share modal.
  • APIPairwise consolidation runs at flush, cutting duplicate facts.
Fixes5
  • Chat — empty tool-loop responses no longer stall the conversation.
  • Discovery — a friendly message when discovery finds nothing, rather than an empty screen.
  • Documents — text extraction failures are handled gracefully; gating no longer blocks users entitled to a document.
  • Onboarding — returning after exiting early puts you back into onboarding, and account deletion redirects to login.
  • APIPersistence — NUL bytes are scrubbed and blank messages fall back to a zero vector instead of erroring.
Security2
  • MCP server — transport-level auth with RFC 9728 discovery, and the public host is allowlisted in DNS-rebinding protection.
  • APIPer-message rate limiting.
