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 and iPad, 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. Say "Log in CogniLog" to start one by voice. 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, and tags take their channel's color. You can ask for things back, too. Say "What did I log today in CogniLog" and Siri lists your entries. In Shortcuts you can add, find and open entries, pull up entries by day, week, channel or tag, search the whole log, and see where your time went. Pair them with Use Model to summarize a week or ask questions about your own work. (Use Model needs a device that supports Apple Intelligence.) Ready-made shortcuts like Summarize my week and Dictate a log entry are on rivetrune.com. 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 works like it does on any iPhone when closed. Open, it puts your log on one side of the fold and your filters or the editor on the other, or gives either one the full screen. Drafts survive folding and unfolding. On iPad On iPad, CogniLog uses the same layout as the Mac: your channels and tags on the left, your log beside them, and a timeline along the edge to jump to any day. The Almanac view fits a whole year on the screen. Write in a pane next to your log, or edit an entry right where it is. Open a second window to keep the Almanac view in one and write in the other. Make a window as small as you like and the layout adjusts, down to the same single column you get on iPhone. A keyboard and trackpad are optional. With them you get the menu bar, keyboard shortcuts and hover previews, like on a Mac. Siri, Shortcuts and widgets work the same as on iPhone. On Mac CogniLog for Mac uses the same log, synced through your iCloud, and it can do more: • 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, write to it, and save or restore backups. • 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, iPad and Mac all write to the same log. About CogniLog is made by Rivet & Rune. Questions, bugs and ideas go to support@rivetrune.com.

Moun is your external memory. Speak naturally and Moun turns it into a task, or a reminder — no forms, no friction. Then it brings things back to you at the exact moment you need them. Most apps let you write things down but never help you find them again. Moun is built the way people actually think: capture fast, let AI organize, and never lose anything. CAPTURE BY VOICE Tap once and talk. Moun understands what you mean and sets up the note, task, or reminder for you automatically. SMART REMINDERS Get reminded by time or by place. "Remind me to call Mario when I get to work" just works, thanks to location-based reminders. PERSISTENT REMINDERS Didn't finish a task? Moun brings it back the next day — and keeps reminding you until it's actually done. FIND ANYTHING WITH AI Don't remember where you saved it? Just describe it. Moun's AI search finds any note, moment, or reminder in seconds. YOUR MEMORY, ORGANIZED FOR YOU Drop things in without worrying about folders. The AI handles the organizing so you don't have to.
