| What you compare | Task Machine | Notion Custom Agents |
|---|---|---|
| Goals |
Task Machine
Yes
Give a Goal an agent lead and link Metrics, such as weekly signups or open pipeline value. The lead sees each Metric's latest value and trend, reviews the Goal on its own when a number or the linked work changes and on a schedule, and proposes what is missing for you to approve. |
Notion Custom Agents
Partly
Notion documents objectives with owners, measurable key results and progress tracking. Its example database calculates progress from current, initial and target values, rather than requiring an agent to own the goal. |
| Leads |
Task Machine
Yes
Goals, Projects and Teams each have a lead, a person or an agent. A Goal lead checks that the work can still reach the outcome. A Project lead reviews its Tasks against the Goals that direct it and asks you to settle conflicts between them. A Team lead triages the queue. Every gap becomes a proposal you approve. |
Notion Custom Agents
Partly
Managers can oversee projects and team workloads, and Custom Agents can delegate parts of a job. Its docs do not establish a named lead role responsible for reviewing and coordinating a goal, project or team. |
| Tasks |
Task Machine
Yes
Every job is a Task that a person or an agent owns. The Task keeps its plan, discussion, decisions, runs and history together, so you can steer one job in detail without reading a chat log, and people and agents hand work to each other on the same record. |
Notion Custom Agents
Yes
Notion tasks have assignees, dates and status. The separate Claude agents beta accepts assigned tasks and keeps sessions and activity on the page or task where the agent works. |
| Recurring work |
Task Machine
Yes
Start a Task or Workflow once, on a schedule in your timezone, or when a service event arrives, such as a paid invoice or a pull request review. A recurring job keeps one stable root Task and gives each occurrence its own status and history, so repeated work does not flood your board. |
Notion Custom Agents
Yes
Custom Agents run on recurring schedules, Notion changes and Slack events, including messages, mentions and reactions. You can combine trigger types and filter when an agent runs. |
| Workflows |
Task Machine
Yes
A Workflow repeats your steps in the same order every time, with branches, human questions and approvals, and verifier checks that judge each result against its requirements and send weak work back with feedback. Every run keeps a step-by-step history you can read afterwards. |
Notion Custom Agents
Partly
Custom Agents follow instructions and hand work to sub-agents, and Workers add custom code in beta. Its docs do not establish a fixed step-and-branch process for agent runs, and recommend letting the agent determine how to reach the outcome. |
| Autonomy |
Task Machine
Yes
Consequential decisions land in your Inbox with their context. You set what each agent may do on its own: every action is either Ask first or Automatic, per agent, and you can change that whenever the work or the stakes change. |
Notion Custom Agents
Yes
Custom Agent connections let you set individual tools to run automatically or always ask. Users receive confirmation prompts before actions, and unexpected external links generate a notification for approval. |
| Learned autonomy |
Task Machine
Yes
Task Machine studies the approvals and corrections you already make. When an agent does well it proposes giving it more freedom, and when it needs closer supervision it proposes tighter review, each with the evidence. A short lucky streak is not enough, and nothing changes until you accept. |
Notion Custom Agents
Not published
Its docs do not describe proposals to change an agent's permissions based on your approval history. Memories retain context, while approval settings control when the agent asks. |
| Memory |
Task Machine
Yes
Agents keep lessons from your corrections, such as an accepted example or a mistake to avoid, and carry the relevant notes into later work. Memory is kept per agent, project, goal, team and workspace, and you can read, correct and restore any note. |
Notion Custom Agents
Yes
Custom Agents can retain viewable memories across chats and update them from corrections. Personal Notion Agent also keeps a Memories database where you can edit or delete saved context. |
| Planning |
Task Machine
Yes
Plan in Chat with your agents, and the plan becomes Tasks or Library documents instead of staying in a chat log. Before an agent starts, you review its plan and the acceptance criteria its work will be judged against. |
Notion Custom Agents
Yes
Personal Notion Agent can turn a chat request into a launch plan with tasks and owners. Custom Agent creation also lets you review and refine draft instructions, triggers and access before saving. |
| Intake |
Task Machine
Yes
Send work in over HTTP with a project token. It lands in the project as a Task, or in your Inbox as a proposal first. A team lead agent triages it to the right owner and asks you only when the decision is yours. |
Notion Custom Agents
Yes
Task routing agents capture incoming work and route it to a team. Slack messages, mentions and reactions can start a Custom Agent, while connected mail can trigger work from incoming email. |
| Connectors |
Task Machine
Yes
Install services from a catalog as MCP servers, APIs or command-line tools, or add your own custom Connector for any of the three. Events Connectors receive webhooks from a service, such as a paid invoice, and start Workflows or wake a waiting Task. |
Notion Custom Agents
Yes
Custom Agents support a catalog of hosted Model Context Protocol connections and custom servers, with scheduled and event-triggered runs. The Agent APIs also let integrations start chats, submit actions and read session history. |
| Models |
Task Machine
Yes
Auto is the default. For each stage of the work it chooses a model from the task, current model capabilities, pricing and your applicable budgets, and you can fix a specific model on an agent when you want to. |
Notion Custom Agents
Yes
Auto selects models per task and can switch models during demanding steps of a longer job. It is the default for personal Notion Agent and Custom Agents, subject to workspace model restrictions. |
| Cloud or your own computer |
Task Machine
Yes
Run agents in Managed Cloud with nothing to install, or connect a Local Worker, a computer you control, for local files, tools and accounts. You choose where each agent runs. |
Notion Custom Agents
Partly
Custom Agents run inside Notion, and Workers run custom code on Notion's servers. Its docs do not describe running these agents on your own computer or infrastructure. |
| Your own subscription |
Task Machine
Yes
Sign in to your ChatGPT (Codex), Claude or GitHub Copilot subscription on a Local Worker, and the agents there use it instead of Task Machine's models. |
Notion Custom Agents
Partly
Business and Enterprise members can connect a ChatGPT Plus, Pro, Business or Go plan to personal Notion Agent for selected GPT models. This does not work with Custom Agents or Auto. |
| Pricing |
Task Machine
Yes
Usage based. From $29 a month before tax, the whole payment becomes usage that your workspace shares across people and agents, with no base fee and no trial. Larger monthly amounts lower the AI and Cloud rates. |
Notion Custom Agents
Yes
Business is €19.50 per member per month billed yearly on the fetched pricing page. Agent usage draws credits, with purchased Notion credits at $10 per 1,000 monthly or $13 per 1,000 annual credits. |
| Correctness |
Task Machine
Yes
Every Task carries acceptance requirements, and each one gets a Pass, Fail or Uncertain check against the delivered work before a person reviews it. Workflow steps can add a verifier check that sends failed work back with feedback. You review the plan first, so the criteria exist before work starts. |
Notion Custom Agents
Partly
Notion recommends defining done in instructions, manually testing runs and reviewing their outputs and logs. Its docs do not establish automatic checks of delivered results against defined requirements or evaluation criteria. |
For software work
| What you compare | Task Machine | Notion Custom Agents |
|---|---|---|
| Code review rules |
Task Machine
Yes
Internal code review checks completed changes against the enabled rules of your repository. Rule discovery reads the repository and proposes rules, each screened against violating and valid examples first, and Task Machine suggests turning off a rule that agents keep dismissing. |
Notion Custom Agents
Partly
The separate Claude agents beta accepts instructions for coding style, branch names and pull request descriptions. Its docs describe teammates reviewing changes, not an automatic code review against repository rules. |
| Adversarial review |
Task Machine
Yes
When an approved plan has high sensitivity or a Critical review level, the change also gets an adversarial review. Two independent reviewers examine the changed files together for defects such as a broken caller or a duplicate charge on retry. Findings keep their reproduction steps, and a skipped or failed review never counts as a pass. |
Notion Custom Agents
Not published
Its docs do not describe an independent second review of risky code changes. The Claude task-board guide recommends keeping your normal teammate review of the diff and merge. |
| Risk rating |
Task Machine
Yes
Before final review, Merge risk rates the exact revision Low, Moderate or High, with notes on alignment, impact, verification, rollback cost and error detection, plus file references. It informs your decision and never merges for you. |
Notion Custom Agents
Not published
Its docs do not describe a risk rating for a code change before merge. The Claude task-board guide describes flagging risky scope in a product requirements document and leaving merge approval to a teammate. |
| Pull requests |
Task Machine
Yes
Agents deliver against the exact reported revision, address review feedback and update the branch under your repository rules. Task Machine records its own approval of the exact commit before an agent may merge. |
Notion Custom Agents
Partly
The separate Claude agents beta opens GitHub pull requests linked to Notion tasks and accepts direction through task comments. Its docs do not establish handling review feedback from GitHub pull requests. |

Who each one suits
Notion Custom Agents suits you if your team already keeps its work in Notion pages and databases and wants shared agents to route incoming tasks or publish scheduled reports. Personal Notion Agent handles on-demand requests alongside those background agents.
Task Machine suits you if you want people and agents to own Tasks with their plans, discussions and review evidence together. You can link Goals to Metrics, let an agent lead review progress, and handle consequential decisions in the Inbox.
You may stay with Notion Custom Agents if your recurring work already fits its pages, databases, triggers and connected tools. Shared agents, editable memory and automatic model selection are reasons to evaluate the existing setup before moving work.
Keep the work beside its context
Notion Custom Agents use the pages, databases and apps you grant them access to. They can start from schedules or Slack events, split a job among other agents and keep an activity log. Personal Notion Agent can build a launch plan with tasks and owners from a conversation.
Task Machine keeps the job in a Task, with the plan, discussion, decisions and run history together. A Goal can have an agent lead that watches linked Metrics and proposes missing work for your approval.
Choose how results get checked
Notion lets you decide which connected tools must ask before acting. Its guidance for Custom Agents recommends defining done, testing a run manually and checking the output. The separate Claude agents beta adds coding work and pull requests, with teammates reviewing the diff and approving the merge.
Task Machine Workflows define steps, branches and human approvals. A verifier can check an output against requirements and return failed work with feedback. Task reviews also record checks against acceptance requirements before final review.
What the prices cover
The fetched Notion pricing page shows Business at €19.50 per member per month billed yearly, covering a workspace with Notion Agent and access to Custom Agents. Custom Agents normally use their owner's included Select credits, or an administrator can fund them from a workspace budget. Agents created before November 2, 2026 continue using shared workspace credits. Purchased Notion credits cost $10 per 1,000 monthly credits or $13 per 1,000 annual credits, with unused credits expiring at the monthly reset or annual renewal respectively.
Task Machine is usage based, from $29 a month before tax. The whole payment becomes usage shared by the workspace, with no base fee. You keep 100% of your revenue, Task Machine takes no cut, and never takes custody of your accounts. See pricing for what consumes usage. A Notion credit and a Task Machine Task are different units, so compare the work you intend to run.
Common questions
Are Notion Agent and Custom Agents the same?
No. Personal Notion Agent works when you ask, while shared Custom Agents run on schedules or triggers. This comparison covers both and names the separate Claude agents beta where coding features depend on it.
Can Notion use my ChatGPT subscription?
Personal Notion Agent can use an eligible connected ChatGPT plan for selected GPT models on Business and Enterprise. That connection does not fund Custom Agents or Auto.
Can I run the agents on my computer?
Notion documents hosted Custom Agents and Notion-hosted Workers. Task Machine offers Managed Cloud or a Local Worker on a computer you control.
Can both remember corrections?
Yes. Custom Agent memories can retain corrections across chats, and personal Notion Agent lets you edit or delete saved memories. Task Machine keeps readable, correctable memories for later work too.
