You met Sam at the conference. She mentioned her daughter just started at the same college you attended. You meant to follow up with Sam in a month but never did. You didn't forget because you don't care. You forgot because memory doesn't scale the way relationships do. Dots is the memory for your relationships, both personal and professional. You add a dot when you learn something worth remembering. Dots surfaces it when it matters. What a dot looks like: Marcus collects Japanese whisky. Sarah went through a tough move last year. Priya prefers warm intros, and she likes knowing someone before the meeting. Small details. The difference between a generic check-in and a conversation that lands. What Dots does - Remembers the details you'd otherwise lose - Surfaces the right moment to reach out - Keeps follow-ups specific, never generic - Works for the people you love and the people you work with What Dots isn't A CRM. A pipeline tool. Dots doesn't score your relationships or remind you to "engage." It just helps you show up the way you already intend to. A dot is a detail, not a person. Add enough of them, and you'll never forget what matters.

CogniLog is a work log you can read at any distance. In the Almanac view, step back to the year to see which weeks went to which projects, open a week to skim a few lines from each entry, then tap one to read the whole thing. You write the way you normally would, and CogniLog works out the short versions for each view. If you work with AI agents, they can read and write to the same log, so you and your agents work from the same record. On a Mac, an assistant like Claude, or a coding agent like Claude Code or Codex, connects to CogniLog's built-in MCP server. It can look up your past work, answer questions about it, and log what it did and why. Those entries sync to your iPhone, right next to yours. It fits any kind of work. People use it for code, client projects, research, writing and school. On iPhone Write an entry in the app, from a Lock Screen or Home Screen widget, from the share sheet, or with Siri and Shortcuts. Entries are plain text with light Markdown that formats as you type. Add a #tag and the entry is tagged. Channels keep separate projects apart. You can ask for things back, too. Say "What did I log today in CogniLog" and Siri lists your entries. In Shortcuts you can pull up entries by day, week, channel or tag, search the whole log, or hand a week of entries to Apple Intelligence for a summary. (Summaries need a device that supports Apple Intelligence.) The Almanac view shows your log by week, month and year. Tap a day to see what happened, then open any entry. On iPhone Duo, CogniLog uses both sides of the fold, with your log on one side and your filters or the editor on the other. On Mac CogniLog for Mac uses the same log, synced through your iCloud, and it can do more: • The Almanac view fits a whole year on one screen. Hover over a day for a summary of what happened. • Import from apps like Apple Notes, Day One, Obsidian and Bear, or from a folder of Markdown files, and export everything back out as Markdown whenever you want. • The built-in MCP server lets your AI assistants read your log and write to it. • Log from the menu bar or from Spotlight without switching away from what you're doing. If you have a Mac, get CogniLog there too. Your iPhone and your Mac write to the same log. Privacy Your entries stay on your devices and in your own iCloud. The app sends anonymous usage counts that never include anything you write and aren't linked to you. About CogniLog is made by Rivet & Rune.
