Akiflow vs Notion AI vs Superhuman

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

So which one?

Notis aside, Notion AI covers the most ground: 53% across all 33 capabilities, ahead of Akiflow at 42% and Superhuman at 42%.

They are not really after the same job, though: Notion AI for keeping the product and your data under your own control, Akiflow for remembering context between conversations and Superhuman for scheduled and event-triggered work.

Cheapest way in is a tie: Notis and Notion AI all start at $0, and not one of those free plans does the product's main job.

Nothing here publishes anything on Bring your own API key and Run it on your own server.

Only Notis publishes anything on iMessage, Telegram, Runs on your own Claude plan and 6 more rows.

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.

1. Notis

Personal AI assistant

Notis is a personal AI assistant you message from WhatsApp, iMessage, Telegram, Slack or email, and reach from your own coding agent through its MCP server.

Best for: running long jobs on a machine of its own

Bring your own AI: Runs on your own Claude plan, Runs on your own ChatGPT plan, Works inside your own coding agent and You choose which model runs your work

2. Notion AI

AI built into the Notion workspace: a chat agent, autonomous Custom Agents, database automations, and custom-code Workers across your connected apps.

Best for: keeping the product and your data under your own control

Documented strengths

What it can do: Ready-made app integrations, Creates and edits documents, Save your own reusable instructions and Joins and records your meetings
Where you can use it: Slack, Web or desktop app and Its own iPhone or Android app
Memory: Remembers you between conversations and Reads your existing files and apps

Pricing

FreePlus$10/user/moyrBusiness$20/user/moyrEnterpriseCustom pricing

$0–$20/seat/mo (Free $0, Plus $10/mo billed yearly or $12 monthly, Business $20/mo billed yearly or $24 monthly); Enterprise custom pricing; Custom Agents and Workers billed separately in Notion credits (agents $10 per 1,000 credits/month; Workers ~$0.0023/run), both free during their current beta through mid-October 2026 · free tier available · notion.com

Who should pick it

Notion AI is the one to take when keeping the product and your data under your own control is the deciding factor. Walk away if you need it in the other apps you message from.

Our take on how it differs from Notis: Notion AI and its Custom Agents/Workers only run inside the Notion workspace and its connected apps, with no consumer messaging channel (WhatsApp, iMessage, Telegram, SMS) into the assistant; Notis reaches users directly on the channels they already use and executes across model providers without a workspace migration.

A task and calendar consolidator with a command bar, an AI assistant (Aki) reachable in-app, on WhatsApp and by email, and an MCP connector, billed per seat.

Memory: Remembers you between conversations and Reads your existing files and apps

The catch

The documented gap is published guarantees about your data. We found no published support for Open source, Run it on your own server and Published security certification.

Pricing

Team$12/user/moyrMeeting Assistant add-on$19/moPro$19/user/moyr

$12-$34/user/mo (Team: $20 billed monthly / $12/mo billed yearly; Pro: $34 billed monthly / $19/mo billed yearly, 7-day free trial); Meeting Assistant add-on $19/mo · no free tier · akiflow.com

Who should pick it

Worth it for remembering context between conversations: that is what Akiflow is built around. Walk away if you need open source, self-hosting or a named certification.

Our take on how it differs from Notis: Akiflow centralizes tasks and calendars pulled from other tools into its own planner UI, with an assistant (Aki) you reach mainly inside that app, on WhatsApp, or by email; Notis instead executes directly from the channel a message already arrives in (WhatsApp, iMessage, Telegram, Slack, email, voice) without requiring you to adopt a separate planner interface.

4. Superhuman

AI email client and productivity suite

Grammarly's AI productivity suite: an AI email client (Mail), collaborative Docs, and an assistant (Go) that follows you across your apps.

$25–$33 per member/month billed annually (Starter $25, Business $33); $30–$40 per member/month billed monthly; Enterprise custom · no free tier · superhuman.com

Who should pick it

Pick Superhuman if scheduled and event-triggered work 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: Superhuman centers on one email inbox (Mail) plus a writing/Docs suite (Go, Grammarly, Docs), reachable via desktop app, browser extension, mobile app and Slack messages to Go. Notis is reachable on WhatsApp, iMessage, Telegram, Slack, email and voice as well, and executes across model providers rather than one fixed proprietary AI.

Where none of them wins

Nothing on this page publishes anything on Bring your own API key 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.

Questions people ask

Which of Notion AI, Akiflow or Superhuman covers the most features?

Notion AI, at 53% across all 33 capabilities, ahead of Akiflow at 42% and Superhuman at 42%. That counts documented support, not how well any of it works.

Notion AI has a free tier and Akiflow and Superhuman do not.

Which of them work in Slack?

Notion AI and Superhuman do. Akiflow does not.

How was this comparison put together?

We read whatever each product publishes (132 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 Notion AI specifically: Notion AI and its Custom Agents/Workers only run inside the Notion workspace and its connected apps, with no consumer messaging channel (WhatsApp, iMessage, Telegram, SMS) into the assistant; Notis reaches users directly on the channels they already use and executes across model providers without a workspace migration.

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.
