The table they can't print

What leaves your house.

The full local-vs-cloud boundary is on the privacy page. Head-to-heads: vs Alexa · vs ChatGPT.

PHNTM ONE · ALEXA ON ECHO · CHATGPT

Choose the tool for the job. PHNTM One is dedicated local AI hardware. Alexa on Echo is a voice service delivered through a speaker. ChatGPT is a cloud-hosted chatbot. These serve different needs; the table compares their relevant settings and dependencies, not identical products. For DIY local AI, see the buyer’s guide.

PHNTM prioritizes local use and inspectable data. Alexa and ChatGPT have their own privacy controls and strengths. Read both the advantages and the trade-offs before choosing.

WORKS WITH THE INTERNET UNPLUGGED

phntm one

yes — local chat, memory, voice and documents. Reminder timing depends on a verified clock

Alexa / Echo

Voice requests use Amazon’s cloud; other Echo functions vary by model

ChatGPT

WHAT LEAVES YOUR HOUSE

phntm one

no local-chat content sent to a cloud model by default — and the SYS screen counts the connections live, on the box, where you can watch it

Alexa / Echo

Echo requests activated by a wake word or action button go to Amazon for processing under its published Alexa terms

ChatGPT

Chat requests are processed by OpenAI; training depends on your settings

THE DAY THE COMPANY SHUTS DOWN

phntm one

core local functions do not depend on DeCampLabs servers (the continuity page)

Alexa / Echo

Cloud features depend on the provider continuing its service

ChatGPT

Cloud-hosted answers depend on the provider continuing its service

CAN YOU READ THE CODE IT RUNS?

phntm one

yes — readable Python, on hardware you own, SSH documented

Alexa / Echo

ChatGPT

DELETE A MEMORY — AND VERIFY IT'S GONE

phntm one

yes — the MEM screen deletes the record AND the searchable copy, on your device

Alexa / Echo

Deletion is managed through the provider’s privacy controls

ChatGPT

ChatGPT offers memory and chat deletion controls; retained copies follow its published policies

THE MICROPHONE, WHEN YOU'RE NOT TALKING

phntm one

tap-to-talk by default; local wake detection is optional and off until enabled. Tap to talk; it listens only while the red dot shows, then stops on silence, a second tap or after 15 seconds

Alexa / Echo

Echo detects its wake word locally when its microphone is enabled, then sends the request to Amazon

ChatGPT

n/a

COST AND SERVICES

phntm one

$799 when ordering opens. No required subscription for local use.

Alexa / Echo

Lower hardware cost; optional subscriptions and services vary by product

ChatGPT

ChatGPT has free and paid plans; compare the plan you would actually use

Where they win — honestly

THE ROWS WE LOSE

raw intelligence

Frontier cloud models are stronger at complex reasoning than the small local model; PHNTM labels which brain answered

speed

Cloud response speed varies; frontier services generally offer stronger reasoning; ours come at about two words a second (tens of seconds for a short answer, past a minute for a long one) — and the first answer after an idle spell is slower, while the model reloads. The Pi is allowed to be a Pi

integrations

Alexa offers smart-home and service integrations. PHNTM offers optional cloud and account connections; Home Assistant is planned 1.0 scope, not yet release-verified

sticker price

An Echo speaker has a lower hardware price; its purpose and services differ from this dedicated local AI device

If the second table matters more to you than the first, buy their products — genuinely. This device is for people who read both tables and know which one they can't buy anywhere else.
