A list and a card answer different questions
This is the whole argument, and it is smaller than it sounds. You already
use Todoist. It is full of things that matter enough to write down, which
is a high bar. Writing a task down is itself an act of intention, and the
fact that a procedure made the list means you intend to keep doing it.
But a task manager is a machine for not forgetting to act,
and it is not a machine for remembering without looking.
Completion is the terminal state. Tick the box and Todoist’s job is done.
What Todoist cannot do is ask you, three weeks later and with no warning,
what the third step was. That is the question a cloze card asks, and it is
the question a task manager has no way to ask.
Here is the defensible version of the claim, stated honestly, and it is about the plan, not a shipped feature.
Of the competitors we compared (One Sec, Opal, ScreenZen, Freedom, Study
Lock and the Anki-adjacent apps) no competitor we checked
connects a to-do app. Their card sources are built-in
generations, PDF and text uploads, or your own notes. We did not audit
every application store listing on earth, so we are not going to tell you
that nobody has ever built this. We are telling you that among the apps
we checked, on 30 September 2026, this was not there.
How the Todoist connector is planned to work
This is the design, not something you can do in the app today. It is
written down so you can judge whether it is worth waiting for.
-
Connect Todoist with OAuth
You approve access on Todoist’s screen and Popcue receives a token, never your password. You can revoke it from Todoist’s own settings, and revoking there stops the reading immediately.
-
Select the projects
You choose which projects become card sources. A work project, a study list, a personal system, whatever is worth being tested on. Projects you do not select are never read.
-
Tasks become cards across eight card types
A recurring procedure suits a cloze, with one term blanked out of the sentence. A definition suits a plain question. A checklist suits a list card, answered by naming the items. A rule you hold confidently is better tested by being asked to reject it, which is a true-or-false card.
-
The interrupt asks, and the card is labelled Todoist
Every card shows that it came from Todoist, and which project it came from. You pick the apps Popcue wraps; when one opens, a card is on screen. Tap to reveal, tap to rate Got it or Still learning, and the app opens. Nothing is ever ticked off in Todoist.
A worked example: one recurring task, one cloze card
The following is an illustration with invented content, built to show the
shape of the planned transformation rather than to describe anyone’s real
setup, and the connector does not exist in the app yet. It is a recurring
Todoist task in a study project, which is the kind of task this connector
is for.
The task, in Todoist
A recurring task, every Monday, in a project called Placement. Its title is Send Priya the placement feedback before the Monday lab meeting, with a note that says the feedback goes in the shared folder and needs the week’s sample numbers.
The card, in Popcue
A cloze card, one term blanked out: Send Priya the ______ feedback before the Monday lab meeting. The answer is placement. Nothing is secret in it, and that is the point: the content is ordinary, the retrieval is the exercise.
What the transformation actually did, and did not do:
-
It changed the question, not the source. The task text is
still in Todoist, under your account, editable there. Popcue did not fork
it into a private copy that now disagrees with the original.
-
It blanked the term you would otherwise skip past. You
have sent this feedback a dozen times. That is exactly why the third
word is the one worth being made to produce.
-
It turned a recurring task into something schedulable.
Recurrence is a good proxy for “this needs to stay sharp”: the task
comes back on a calendar, and the card comes back on SM-2.
-
It never touched your Todoist state. Answering the
card does not complete the task, snooze it, or write a note back. The
card is a question about the task, not an action on it.
And the reason this is worth doing at all is the one the scheduler
supplies: a card you rate Still learning comes back soon, and one
you rate Got it comes back later. A task manager has no version of
that. How the rating feeds SM-2 is explained
on the how-it-works page.
What is planned for your Todoist material
None of this applies until Todoist can be connected, and it is the design
rather than a description of shipped behaviour. The material goes to
whichever service does the reading. If you connect Todoist, the
material would be read by Todoist. Popcue would ask Todoist’s API
for the tasks in the projects you selected and work with what comes back.
It would not copy your task manager into a silo, and it would never write
back.
- What leaves your device
- Requests to Todoist’s API for the projects you selected, and the card text Popcue generates from the tasks those projects contain. It travels over Todoist’s own HTTPS API, under a token you granted and can revoke.
- What does not leave your device
- Your Todoist password, which Popcue never sees. Projects you did not select. Anything from apps you wrap, beyond the fact that one of them opened. And any write-back: Popcue never completes, snoozes, renames or edits a Todoist task.
- What Popcue stores itself
- The connection configuration, the card state the SM-2 scheduler needs, and your ratings. Not a mirrored copy of your task manager.
- How to stop it
- Revoke the integration from Todoist’s own settings, or disconnect it inside Popcue. Either way the reading stops at once and your tasks stay where they were.
Do not connect the projects you would rather not be asked
about. Task lists are where private things end up: a colleague
by name, a medical appointment, a salary. Select the projects you would
be comfortable being quizzed on and leave the rest disconnected. Popcue
can only ask you about what you point it at.
Questions people ask about the Todoist connector
Can I connect Todoist to Popcue today?
No. Todoist is coming soon. The Popcue app lists it as Coming soon and cannot connect it yet. Notion, AnkiDroid and your own MCP-compatible LLM endpoint are the connectors to use now, and you can join the waitlist to hear what ships.
Why connect a to-do app to a flashcard app?
Because the two answer different questions. A to-do list answers what to do next. A flashcard answers whether you still know it. Popcue reads the same task and asks it back as a recall question, so a procedure you run every week stays available in your head instead of only in your task manager.
Will the Todoist connector complete tasks for me?
No, and it is designed not to. Answering a card in Popcue would never check a task off in Todoist and never write to your Todoist account. Popcue would read the tasks you selected and ask you about them, so a task you have already ticked could still be asked as a cloze, which is the point: retention outlives completion.
Will I be able to connect Todoist and Notion at the same time?
That is the design, but not yet, because Todoist cannot be connected today. Each connected source becomes its own learning path with its own cards, the interrupt draws from all of them, and every card shows which service it came from, so a Todoist task and a Notion page would never be confused for one another.
