Case study · Tuck · My own product

Save a link in one tap. Get it back tonight.

I kept sending links to myself on WhatsApp, where they sank under real messages and died. So I made Tuck. I wrote the requirements, designed the brand and every screen, and built it with AI coding tools: a Windows app I use every day, an iPhone app and a browser add-on, all synced.

CtrlVis all it takes on Windows

The problem

Links I sent myself sank within a day.

I find things on my phone, on the go, and act on them later at my laptop. So every link went to my own WhatsApp chat. Then real messages piled on top, nothing ever brought them back, and job posts closed before I looked again.

What success had to look like, measured on myself over three weeks

  1. 01I stop sending links to WhatsApp.
  2. 02After week one, most saves land in the right topic without me fixing it.
  3. 03I open Tonight at least four nights a week.

How it sorts itself

Every link drops until something knows where it goes.

Tuck picks a topic on the device, with no server and no paid AI. It checks four things in order and stops at the first one that knows. When I move a save, it remembers, so the next link like it lands in the right place.

  1. 01My past correctionsI moved a link from this site before, so this one follows.
  2. 02Link patternsCareers pages, LinkedIn jobs and job boards mean Jobs.
  3. 03Words in the title"Framer", "how to", "tutorial" and "hiring" each point somewhere.
  4. 04Not sureIt files the link under Unsorted and suggests a name. No guess dressed up as an answer.

Where they land: the Jobs topic, with a LinkedIn job Tuck couldn't read still shown as a proper card.

Getting it back

39 saves. At 8pm, three.

A reminder only works if I act on it. So the evening doesn't dump everything on me. Tuck leads with three picks, says how long they'll take, and keeps coming back for anything I ignore, until I decide.

On the phone

Most links find me on my phone. Saving one is a single tap.

The iPhone app opens straight to one button. Copy a link anywhere, open Tuck, tap. Everything else is the same library and the same evening as on my laptop, sized for a thumb.

  1. Tuck on iPhone, home: one large round button with a lime ring, Link ready. Tap to tuck, and 15 tonight with Open library below.
    01Copy, then tap

    Open Tuck and it has already found the copied link. The ring lights up lime.

  2. The Tuck this sheet for a TikTok video: a note field, Topic set to Unsorted, Remind me with Tonight 8pm, Tomorrow 9am, Weekend and Custom, and a Tuck it button.
    02Say what it's for

    A note, a topic and a time to be reminded. All optional, so a tap on Tuck it is enough.

  3. The Library: a card asking to merge two look-alike topics, 15 to check tonight, filters by source, and topic folders such as All saves with 62 saves.
    03A library of folders

    Topics look like folders with the saves peeking out. When two topics look alike, Tuck offers to merge them.

  4. Tonight on iPhone: Your 3 picks, and 12 more. A card for Design Jobs from recent.design, waiting 23 days, with Open, Not tonight and Done, and Show 12 more tonight.
    04Three picks tonight

    Move, remind, pin, share or delete without opening anything.

Where it stands

It costs nothing to run. I use it every day.

Tuck runs on free plans from end to end, and the Windows app is open on my laptop every day. Keeping it free shaped how I built it.

Tuck for Windows in dark mode, the library: seven topic folders in soft colours, each holding the covers of its saves.

  1. 01Small updates for slow internet

    Tuck for Windows updates itself in the background and downloads only the parts that changed, never the whole installer again.

  2. 02Sorting that learns from me

    Tuck files each link on the device and learns from every move I make, with no account or key to set up. Smarter AI sorting is next, through people's own ChatGPT plans.

  3. 03One library on every device

    A save on my phone shows up on my laptop, and the other way round. Sync and sign-in run on Supabase's free plan.
