| What you compare | Task Machine | Sintra |
|---|---|---|
| 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. |
Sintra
Partly
Buddy helps with business strategy and Dexter produces sales and performance reports. Its docs do not describe an agent owning a goal with a tracked target and reviewing progress against it. |
| 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. |
Sintra
Yes
Team Chat has a Team Leader that plans work, delegates parts to specialists and brings their results together. The overview describes Team Chat as beta on workspace plans. |
| 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. |
Sintra
Partly
Scheduled tasks can be assigned to a Helper, and each executed task opens a chat for feedback. Its docs do not describe assigning the same work item to a person as its owner. |
| 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. |
Sintra
Yes
Helpers run work on recurring schedules, while built-in automations can start from events such as a new email. Scheduled tasks can use connected apps and business knowledge. |
| 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. |
Sintra
Yes
You can describe a repeatable multi-step workflow in chat and save it as a skill. Sintra says these skills run the same way every time, such as checking a price list before preparing a quote. |
| 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. |
Sintra
Yes
Sending, publishing, scheduling and spending show approval cards in chat. You can save rules about asking first and deliberately configure scheduled tasks to act without 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. |
Sintra
Not published
Its docs do not describe proposing permission changes from a history of approvals and corrections. Saving a correction as a rule is described as something you request. |
| 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. |
Sintra
Yes
Brain AI keeps business knowledge and context for later chats across Helpers. You can add, edit, search and remove its contents, and ask Helpers to find conflicting information. |
| 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. |
Sintra
Partly
Team Chat's leader plans and delegates work, and Helpers create campaign plans. Its docs do not establish a separate plan artifact or a plan review before execution. |
| 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. |
Sintra
Yes
Cassie's Inbox Manager receives new Gmail and Outlook messages, categorizes them and drafts replies for messages needing a response. You review the draft before sending it. |
| 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. |
Sintra
Partly
Sintra offers a catalog of connected apps and event-driven automations. Its docs say it provides no public API and do not describe custom HTTP connections or Model Context Protocol servers. |
| 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. |
Sintra
Not published
Its docs name several text and image models but do not describe automatic model selection for each task or step. Automatically assigning a Helper is a separate feature. |
| 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. |
Sintra
Partly
Sintra provides its hosted web app and synchronized mobile apps, and work continues when you close the app. Its docs do not describe a local execution runtime or self-hosting option. |
| 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. |
Sintra
Not published
Its docs describe workspace credits funding AI model use. They do not describe connecting your own AI subscription or provider API key to pay for that usage. |
| 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. |
Sintra
Yes
Promotional Sintra X prices are $48.50 monthly, $23.60 per month on a 3-month term, or $15.60 per month on a 12-month term, paid upfront. Each includes 250 monthly credits and all 12 core Helpers. Tax is added at checkout. |
| 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. |
Sintra
Partly
Sintra asks you to fact-check text and review images, and its automations collect drafts for approval. Its docs do not establish result checks against defined evaluation criteria or acceptance requirements. |
For software work
| What you compare | Task Machine | Sintra |
|---|---|---|
| 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. |
Sintra
Not published
Its docs describe building and editing static websites, but do not describe reviewing generated code 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. |
Sintra
Not published
Its docs do not describe an independent second review of risky code changes. Team Chat's delegation and marketplace listing reviews do not establish that process. |
| 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. |
Sintra
Not published
Its public pages describe a GitHub integration but do not describe assigning a risk rating to a code change before merge. |
| 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. |
Sintra
Partly
Sintra's GitHub integration manages issues and pull requests and tracks development tasks. Its docs do not establish agents implementing code changes and addressing pull-request review feedback. |

Who each one suits
Sintra suits you if you want business specialists for social posts, customer email, sales copy and reports, sharing the same business knowledge. Its Team Chat can coordinate those specialists in one conversation.
Task Machine suits you if you want people and agents to own Tasks, work toward Goals with linked Metrics, and review plans and acceptance requirements before execution.
You may stay with Sintra if its shared Brain AI, scheduled Helpers and draft approvals already fit your marketing and administration. Its saved skills can repeat a multi-step process without you repeating the instructions.
How you direct the work
Sintra organizes work through Helper chats and scheduled tasks. A Team Leader plans work and brings specialist results together. You can save a method as a skill and a correction as a rule. Brain AI supplies shared business context that you can inspect and edit.
Task Machine keeps a job's plan, discussion, decisions and run history on an owned Task. A Goal can have an agent lead and linked Metrics, so the lead reviews progress toward a measurable outcome and proposes missing work for approval.
Sintra asks for approval before sending or publishing from chat, with an explicit exception for scheduled tasks you configure to act without approval. Task Machine lets you set Ask first or Automatic per action and agent, with decisions gathered in the Inbox.
What you review before calling work done
Sintra's guidance asks you to fact-check text and review images. Its built-in email and social automations prepare drafts for approval. Its public docs do not establish automatic checks against task acceptance requirements.
Task Machine checks delivered work against the requirements on its Task before a person reviews it. Workflows can also check a step's result and return failed work with feedback.
Sintra's Website Builder produces static HTML, CSS and JavaScript sites, and its GitHub integration manages issues and pull requests. Those features are narrower than a documented process for implementing changes and responding to code review.
What the prices cover
Sintra's current promotional Sintra X offers are $48.50 for one month, $23.60 per month on a three-month term, and $15.60 per month on a twelve-month term. Terms are paid upfront. Each includes all 12 core Helpers and 250 credits each month, regardless of the term. Its help page says value-added tax is added at checkout. The help page's annual table and paragraph disagree on the full-year total, so confirm the final amount before paying.
Task Machine is usage based, from $29 a month before tax, with the whole payment available as usage shared by your workspace and no base fee. You keep 100% of your revenue, Task Machine takes no cut, and it never takes custody of your accounts.
Common questions
Can Sintra's Helpers work together?
Yes. Team Chat uses a Team Leader to plan work, delegate to specialists and combine results. Its overview calls Team Chat beta and limits it to workspace plans.
Can Sintra receive customer requests?
Yes. Cassie's Inbox Manager categorizes incoming Gmail and Outlook messages and drafts replies. You review and send them. Task Machine can receive work over HTTP and route it to an owner through task intake.
Does Sintra run on my own computer?
Its docs describe web and mobile apps, not a local execution runtime. Task Machine offers Managed Cloud or a Local Worker on a computer you control.
Can I bring an AI subscription to Sintra?
Its docs describe Sintra workspace credits for model usage, not connecting your own AI subscription or provider key. That funding option remains unverified.
