Why I built InboxLearn

I needed a learning app I did not have to open.

I am Pranay, an engineer. I like learning about photography, design, and anything else that catches my attention. But these interests rarely survive a busy week.

Read what I tried
What I tried first

Every tool wanted more from me than I wanted from the topic.

  1. 01

    Videos gave me pieces.

    One Sunday, I opened a folder of saved photography videos. The next video repeated the same composition basics.

    When I returned a few weeks later, I had no record of what I had covered and no clear next video.

  2. 02

    Courses gave me order.

    They also wanted more time than I wanted to give a passing interest.

    A teacher felt excessive. The courses I tried could not skip what I knew, answer a side question, or adapt to what I was missing.

  3. 03

    AI gave me answers.

    It kept the context, adapted to my questions, and explained things at my level.

    But it still waited for me to come back and ask. I wanted the next useful lesson to arrive without another decision.

  4. 04

    The tool had to act first.

    • Make the learning plan.
    • Remember my place.
    • Send one next lesson.
    • Wait when I skip it.

    One learning plan. One next lesson. No demand to care more.

A reason to keep testing

The research made me think I may not be the only one.

I built InboxLearn to solve a problem in my own life. Then I found research showing that many adults want to keep learning, but time and follow-through often get in the way. That makes me hopeful that this may be an unmet need for other people too.

74%

Many adults keep learning because they are curious.

In a 2016 Pew Research Center survey, 74% of U.S. adults said they had done at least one activity to learn more about a personal interest during the previous year.

What this means for InboxLearn: That is the kind of learning I care about here. It can make life richer even when no job, exam, or deadline depends on it.

Many people want to learn more, but life gets in the way.

The OECD found that one in four adults wanted to take part in more learning but faced a barrier. Among adults who faced a barrier, 48% said work or family left too little time.

What this means for InboxLearn: That sounds like the problem I had. I wanted to learn, but I did not want a new schedule. InboxLearn keeps each lesson small and lets it wait without guilt.

14 points

A personal email can help a busy learner keep moving.

In a small study of 39 full-time professionals, the chance that coursework was on time was 14 percentage points higher after a personal email reminder than after a general reminder.

What this means for InboxLearn: This is one reason InboxLearn sends the next lesson by email. The email remembers the next step and brings it to the learner, so the learner does not have to remember to come back.

40 studies

A short lesson still needs to teach something useful.

A recent review looked at 40 microlearning studies. It found that strong short lessons need a clear goal, useful action, learner fit, and the right way to deliver the content.

What this means for InboxLearn: InboxLearn should not just cut a long lesson into smaller pieces. Each lesson should explain one idea clearly, connect it to the learning plan, and give the learner something useful to try.

The strange product rule

The app should care exactly as much as I do.

Most learning apps try to pull me back.

They use streaks, reminders, large libraries, recommendations, ads, and upgrades. Those things can help when the skill matters a lot. For a passing interest, they make learning feel like work.

The rule
Low interest should mean low pressure.

InboxLearn keeps the learning plan moving without a streak, overdue list, or demand to visit another app.

When InboxLearn fits

It is for a skill that would be nice to have. If an interview, exam, or hard deadline depends on it, use a teacher or a serious course.

Available today
Pause, resume, stop, ask for the next lesson, or reveal a self-check answer on the web or by email reply.
Still building
Ask open-ended questions by email, add current research, and include useful videos without losing the learning plan.

Arrive where I already am

Send the complete lesson by email. Do not make me remember to open another app.

Wait without making a pile

If I have time, I read it. If I do not, it waits in my inbox. There is no streak to repair or overdue list.

Keep practice optional

Offer a quick check or something to try. Let me skip it when I only have time to read.

Let me change course

Let me pause, reschedule, stop, or take a detour without losing the learning plan.

The honest ending

I still do not know if this will work.

InboxLearn is an experiment on myself. Research supports pieces of the idea. I do not know whether months of small lessons will turn a passing interest into a skill I can use.

If you have a topic like that, you can try the experiment too.
