In their own words
Mem Agent
Mem Agent is an AI thought partner for capturing ideas, meetings and research, then retrieving them when needed. Mem Chat can answer workspace questions, create or update notes, organize them and draft content using workspace context. Deep Search accepts natural-language descriptions of what a user wants to find. Voice Mode records and transcribes meetings or spoken thoughts into structured notes. The Chrome extension captures and summarizes webpages and YouTube videos, organizes clips into collections and lets users edit notes from its popup; it is currently available only for Google Chrome. Mem connects to Google Calendar and Microsoft Outlook, but only displays meetings with two or more guests. It can connect to Claude to search Mem knowledge, save conversations as notes, update documents and organize a workspace. The free plan includes 25 messages and 25 new notes per month, tracking for 25 notes, 15 open tasks and projects, and three Voice Mode hours. Mem Plus costs $9 a month. Content is encrypted in transit and at rest, but is unencrypted for AI processing by trusted third-party vendors. Mem supports one-click exports of notes and collections as Markdown files.
TiddlyWiki
TiddlyWiki is a free, non-linear notebook and interactive wiki for organizing and sharing notes, to-do lists, projects, and websites. It stores information in small units called tiddlers, which can be linked and grouped with tags, lists, and macros. Search spans tiddlers and supports filtering system and shadow tiddlers. In its single-file form, the data and code are held in one HTML file that runs in a browser without installation or external dependencies. Users can import material from files or other TiddlyWiki windows, and extend a wiki with plugins, themes, colour palettes, widgets, and macros. It can also run as a Node.js application; that setup offers more capability but takes more technical knowledge to set up and maintain. Saving choices vary, including storage and sync options such as Google Drive, iCloud, Dropbox, and Syncthing. The built-in encryption for single-file wikis has not undergone rigorous third-party testing. TiddlyWiki is available across web, mobile, desktop, and self-hosted setups.
