A trusted agent. Not a chatbot.

Handfast is an agent that lives in your inbox and operateson your behalf — with permission, on a leash, and on the record. It calls Hulu’s retention line, disputes the oddball medical charge, files the return you’ve been putting off — keeps a timestamped audit trail of every move, and waits for your “yes” before anything irreversible ships.

One inbox. Permissioned access. A full audit trail. Nothing moves without your approval.

Permissioned, not omnipotent

Scoped, revocable access — never a blanket login.

Auditable, by default

Every call, email, and decision is timestamped and replayable.

You approve before it moves

No charges, no cancellations, no contracts without an explicit “yes”.

Three examples

The shape of the work. In concrete detail.

Not a category grid. Not a “six things we can do” roundabout. Three real tasks, end-to-end, so you can see exactly what it means to hand one off.

Example · 01

Cancel a Hulu subscription.

You forward the welcome email and ask Handfast to cancel. It pulls your plan, billing date, and free-trial status, then dials Hulu’s retention line on your behalf — navigating the menu tree, sitting on hold, and asking for the retention team when the first agent pushes back.

It documents the call in real time (timestamped transcript), files the cancellation in the portal as a backup, and emails you a single-line receipt — “Hulu cancelled, $0.00 charged for the final cycle.” — with the transcript attached. Nothing moved without your “yes, take the call.”

  • · Reads the bill, drafts a cancellation plan
  • · Calls retention, navigates the tree
  • · Logs the call, timestamped and replayable
  • · Files it in the portal as a backup path

Example · 02

Dispute a medical bill.

You forward the EOB and the itemized hospital statement — the one with the $1,400 charge for an X-ray you don’t remember getting. Handfast parses the CPT codes line by line, cross-checks them against your insurer’s fee schedule, and drafts a dispute letter that names each contested line item.

It submits to the hospital’s billing office, replies to the follow-up email from their appeals team, and keeps the thread on file — every exchange timestamped. Net result lands in your inbox with the adjusted total: a clean receipt you can read in five seconds.

Example · 03

Return an Amazon order.

You send the order number and a one-line reason (“wrong size, ordered by mistake”). Handfast opens the RMA in your account, picks the correct drop-off option for your zip, and pulls a prepaid shipping label into your inbox — the QR for the Whole Foods counter, not the dead UPS dropoff two towns over.

It watches the tracker, files the refund claim the moment the package lands, and pings you when the credit hits. If the return window closes first, it tells you why — with the timestamp.
