Bo AI vs Noah AI vs Tomo

The same 33-row checklist and the same rules. Every cell shows vetted official evidence or “Not checked.”

So which one?

The catch with each one

Numbered by support score across vetted capability rows, with incomplete evidence shown on every card. Unknown rows never count as a no, and this is not a score against your answers.

$49/month · no free tier · heynoah.io

Who should pick it

Noah AI is the one to take when remembering context between conversations is the deciding factor. Walk away if you need open source, self-hosting or a named certification.

Our take on how it differs from Notis: Noah is a narrow executive-admin assistant (calendar, email threads you CC it on, reminders, phone calls) on one undisclosed model stack; Notis adds Telegram and a voice channel, lets you choose the model and bring your own subscription or key, and runs a far broader tool and automation layer.

A text-first AI personal assistant that runs your day over iMessage and SMS, with a strong health, nutrition and habit-tracking bent.

Best for: scheduled and event-triggered work

Documented strengths

Where you can use it: iMessage, SMS or a phone number and Its own iPhone or Android app
Memory: Remembers you between conversations and Reads your existing files and apps

Who should pick it

Worth it for scheduled and event-triggered work: that is what Bo AI is built around. Walk away if you need it in the other apps you message from.

Our take on how it differs from Notis: Bo is a consumer health-and-habits coach on iMessage/SMS that runs on one fixed model provider; Notis is a multi-channel work assistant with an execution layer across model providers and business integrations.

From $19.99/mo (App Store: Tomo Pro $19.99 in-app purchase, also a $119.99 Tomo Pro option); higher messaging-limit plans not publicly priced · no free tier · tomo.ai

Who should pick it

Pick Tomo if reaching it from the apps you already message in is what decides it for you. Walk away if you need it in the other apps you message from.

Our take on how it differs from Notis: Tomo is a consumer accountability coach you reach by texting a vendor number over iMessage or SMS (plus an iOS app), with no model choice, no published integrations directory, API or automation builder. Notis spans WhatsApp, iMessage, Telegram, Slack, email and voice with an execution layer across model providers.

Where none of them wins

Nothing on this page publishes anything on Bring your own API key, Open source and Run it on your own server. If one of them is the thing you actually need, none of these is your answer.

One more thing, because a table like this can be read for more than it is worth. It counts what each product documents. It says nothing about how reliable any of them is, how fast it replies, how good its writing is, or what it does when an integration breaks on a Friday night. A lower support score can still be the better daily driver. The only way to know is to put a real week of work through both.

A dash means the capability was not documented on the official pages we checked. Not checked means the evidence is still incomplete.

Noah AI and Tomo do not have one and free-tier availability is not checked yet for Bo AI.

Which of them work in Its own iPhone or Android app?

Bo AI and Tomo do. Noah AI does not.

How was this comparison put together?

We read whatever each product publishes (82 first-party sources across 4 products) and scored all of them on the same 33 rows. Last checked 21 August 2026. A dash means the capability was not documented on the official pages we checked. Not checked means the evidence is still incomplete.

Where does Notis fit in?

At number 1, scored by the same code on the same 33 rows as everything else. Against Noah AI specifically: Noah is a narrow executive-admin assistant (calendar, email threads you CC it on, reminders, phone calls) on one undisclosed model stack; Notis adds Telegram and a voice channel, lets you choose the model and bring your own subscription or key, and runs a far broader tool and automation layer.

How we checked all this

We read what every product on this page publishes (docs and pricing pages where there are any, the homepage where that is all there is) and checked it against the same 33 buyer-focused rows. A support score uses only rows with an explicit vetted state; every unchecked row remains visible and never becomes a no. Notis chose the questions and is scored by the same rule. Count the links below before you weigh a result; some vendors give us three pages and some give us one. Last checked 21 August 2026. No vendor briefings, no affiliate links, no press releases.
