There is an email in your inbox right now that actually matters. It is under newsletters you never signed up for, and you will find it tomorrow. Maybe. That is not your fault. Email is the only place where anyone on earth can reach you without asking first. Docket gives your inbox a door. WHAT A DOCKET IS A private space you share only with the people you invite. One for your team. One for your family. One for a single person. One just for you. Only the people you invite can post to it. HOW THINGS GET IN Every docket has its own email address. Forward an email to it from the address you signed up with, and it lands in the docket, out of your inbox. Or write straight into it. A note, a checklist, a status update, a meeting agenda, a journal entry. GETTING THINGS DONE Catch me up. A short summary of what is new since you last looked, instead of a pile. Needs you. The questions and action items pulled out of long messages, so nothing waits on you without you knowing. Shared checklists everyone in the docket can tick off, with due dates you type in plain English. Every tick shows who did it and when, so nothing sits in the gap between two people. The Vault. Every file, link and document that passes through a docket is kept there and searchable months later. Replies in your own time. No typing indicators, no online dots, no read receipts. Turn notifications on for the dockets that matter to you, and flag a briefing as priority so it stands out in the feed. Everything else stays quiet. WHY IT IS NOT ANOTHER CHAT APP Your inbox lets everyone in. Group chats bury what matters under everything else. A docket holds a small number of people and the things that matter between you, in one quiet place that is still there in six months. Folders keep your dockets in order as they add up. PRIVACY Encrypted in transit and at rest, stored with AES-256-GCM. We never sell your data. FREE, AND IT STAYS FREE Up to five dockets of your own, up to ten people in each, 1 GB in your Vault, and every format. No credit card. DOCKET PRO Unlimited dockets, unlimited people in each, 10 GB of storage, and a shorter custom email address. $4.99 a month or $39.99 a year.

Verdict
The clearest difference is ads: Docket at none against SecondBrain's shown. Docket also leads on update cadence (daily vs every 3 days). On price, in-app purchases, monetization model and device support there is nothing between them.
