Notis vs Duet vs Lindy

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

Visit Notis Visit Duet Visit Lindy Notis alternatives Duet alternatives Lindy alternatives

So which one?

Notis aside, Duet has the highest checked-evidence score: 61% across 33 vetted rows (all 33). Lindy: 61% across 32 vetted rows; 1 row is not checked yet.

They are not really after the same job, though: Duet for combining AI agents with human checkpoints and Lindy for deploying automation across a team with the right ownership model.

Cheapest way in is Notis at Free–$149/mo, though its free plan only does part of the job.

Nothing here publishes anything on Visual workflow builder, Conditional branches and Loops and batch processing.

Only Notis publishes anything on Webhook or API trigger.

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. Duet

Cloud AI coworker for recurring operations and internal app building

A persistent, cloud-hosted AI coworker that runs a small business's recurring work on schedules, events, and demand, and builds and hosts the internal apps that work needs.

Best for: combining AI agents with human checkpoints

Documented strengths

AI & human control: AI model steps, Autonomous agents, Knowledge bases or RAG, Browser or computer use, MCP support and Human approval steps
Build & trigger: Build workflows with natural language, Schedule trigger, App-event trigger and Email, form, or manual trigger
Platform & governance: Ready-made app integrations, Managed cloud, Audit logs and compliance and Shared team workspace

The catch

Official evidence records a gap in platform and governance options: no published support for Open source, Self-hosting and Usable free tier.

Who should pick it

Pick Duet if combining AI agents with human checkpoints is what decides it for you. Walk away if you need integrations, self-hosting, governance or team controls.

Our take on how it differs from Notis: Duet is a company-facing automation coworker with its own managed VM, credit-metered scheduled/event workflows, and built-in app hosting; Notis is a personal and team assistant reachable from everyday channels (WhatsApp, iMessage, Telegram, Slack, email, voice) with an execution layer across model providers.

2. Lindy

Slack-native AI teammate

A Slack-native AI teammate that runs your inbox, calendar and meetings, and takes on multi-step work across 1,000+ connected apps.

Best for: deploying automation across a team with the right ownership model

Documented strengths

Platform & governance: Ready-made app integrations, Workflow templates, Managed cloud, SSO and role-based access, Audit logs and compliance and Shared team workspace
AI & human control: AI model steps, Autonomous agents, Knowledge bases or RAG, Browser or computer use and Human approval steps
Build & trigger: Build workflows with natural language, Schedule trigger, App-event trigger and Email, form, or manual trigger

The catch

The checked gap is AI and approval controls. Nothing published on MCP support.

Who should pick it

Lindy is the one to take when deploying automation across a team with the right ownership model is the deciding factor. Walk away if you need AI, browser use, MCP or human approval steps.

Our take on how it differs from Notis: Lindy goes deep on Slack-based teamwork, inbox management and meeting handling with strong admin/approval controls; Notis offers more personal channels (WhatsApp, Telegram, iMessage), user-owned agents, and a portable CLI/MCP execution layer that Lindy does not publish.

3. 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: building workflows and starting them the way your work arrives

Documented strengths

Build & trigger: Build workflows with natural language, Schedule trigger, App-event trigger, Webhook or API trigger and Email, form, or manual trigger
AI & human control: AI model steps, Autonomous agents, Knowledge bases or RAG, Browser or computer use and MCP support
Reliability & operations: Run history and logs, Testing and debugging and Secret management

The catch

The documented gap is platform and governance options. We found no published support for Open source, Self-hosting, SSO and role-based access and Audit logs and compliance.

Who should pick it

Worth it for building workflows and starting them the way your work arrives — that is what Notis is built around. Walk away if you need integrations, self-hosting, governance or team controls.

Where none of them wins

Nothing on this page publishes anything on Visual workflow builder, Conditional branches, Loops and batch processing, Data mapping and transforms, Monitoring and alerts, Open source and Self-hosting. 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 Duet or Lindy scores highest in the evidence checked so far?

Duet, with 61% across 33 vetted rows (all 33). Lindy: 61% across 32 vetted rows; 1 row is not checked yet. Unknown rows stay out of the score, so treat this as an evidence status, not a complete market verdict.

How much do they cost?

Duet: $20–$200/month (7-day free trial, no card required); Lindy: $29.99–$199.99/user/mo (Plus/Pro/Max), Enterprise custom. Notis is the cheapest way in at Free–$149/mo, though its free plan only does part of the job.

Which of them can I try for free?

Duet and Lindy do not have one.

What can none of them do?

Not one of them publishes anything on Visual workflow builder, Conditional branches, Loops and batch processing, Data mapping and transforms, Monitoring and alerts and Open source. A dash means the capability was not documented on the official pages we checked. Not checked means the evidence is still incomplete.

How was this comparison put together?

We read whatever each product publishes — 97 first-party sources across 3 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 3, scored by the same code on the same 33 rows as everything else. Against Duet specifically: Duet is a company-facing automation coworker with its own managed VM, credit-metered scheduled/event workflows, and built-in app hosting; Notis is a personal and team assistant reachable from everyday channels (WhatsApp, iMessage, Telegram, Slack, email, voice) with an execution layer across model providers.

How we checked all this

We read every product on this page against whatever it publishes — docs and pricing pages where there are any, the homepage where that is all there is — 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.
