Promise Ledger
Private prototype testing in progress

Every customer promise, captured before it gets forgotten.

Promise Ledger works beside Gmail and Outlook — detecting commitments your team makes in email and post-call notes, and turning the ones you approve into a shared, accountable ledger. Keep using your inbox exactly as you do today.

Read-only access. Nothing becomes official until an employee approves it.

Message to Maya · Halcyon Health

Hi Maya, thanks for the call. I'll send the revised implementation plan by Friday afternoon, and our engineering team will confirm whether SSO can be included by next Tuesday.

Two separate promises are detected in this one message

Companies make promises to customers constantly. Most of them are never tracked.

Buried in email threads

A commitment made on message four of a twelve-message thread is easy to make and easy to lose.

Said out loud, never written down

Calls end, notes don't get taken, and what was promised lives only in someone's memory.

Scattered across inboxes

Every employee's mailbox is its own silo. Managers have no single view of what the company owes.

Dependent on memory

Existing CRMs and task tools only help if someone remembers to copy the promise in manually.

How it works

1

Detect

Promise Ledger reads customer-facing threads and post-call notes to spot likely commitments — deliverable, owner and deadline.

2

Confirm

Right inside Gmail or Outlook, the employee reviews each suggestion, corrects anything wrong, and confirms or dismisses it. Nothing is official until they do.

3

Track

Approved promises live in one ledger with an owner, a due date and a link back to the original evidence — until they're completed.

Keep using Gmail and Outlook. Promise Ledger works beside your inbox.

Employees review and confirm detected promises right where the conversation happened, without changing tools. Managers see the same approved promises rolled up into one company-wide ledger — a separate surface for oversight, not a replacement inbox.

Find out what you've already promised.

When a mailbox first connects, Promise Ledger can securely review recent customer conversations and surface commitments that may still be outstanding. This is always permission-based, always optional, and every finding goes through human review before it counts as an official promise.

  • You choose the scan window — new emails only, 30 days, 90 days, a custom range, or the entire mailbox.
  • Nothing is scanned secretly. The scan runs once you explicitly start it.
  • Findings land in a review queue — they never become official promises automatically.

Try the interactive post-call demo

The meeting itself is never recorded or transcribed.

Calls, without recording anything.

After a scheduled external meeting ends, Promise Ledger simply asks the employee whether the company made any promises. They can say no, type a short note, or leave a voice note of up to 30 seconds — a personal recollection, not a recording of the call. That note is turned into reviewable promise suggestions, the same as an email would be.

Built for customer-facing teams

Agencies & consultancies

Client commitments made across dozens of active engagements, tracked in one place instead of each account lead's inbox.

SaaS customer success

CSMs promise fixes, features and timelines on calls and in email — Promise Ledger keeps every one visible to the team.

Recruitment firms

Commitments to clients and candidates about timelines, paperwork and follow-ups, tracked without extra admin.

Managed service providers

SLA-adjacent promises made in support threads get an owner and a due date instead of disappearing into a queue.

Built to earn trust, not just adoption

We're early — this is a working prototype we're validating with a small circle of private testers. Here's what's designed in from day one rather than bolted on later.

  • Read-only email access — Promise Ledger never sends or deletes on your behalf.
  • An employee approves or edits every AI suggestion before it becomes an official promise.
  • No permanent copy of your full mailbox is stored.
  • Every promise links back to the original message as evidence.
  • No call recording, ever.

Stop losing track of what your company has promised.
