Mem Agent vs SilverBullet

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.

SilverBullet is a Markdown knowledge system for personal notes, team wikis, product documentation, and family spaces. Each space is a folder of plain Markdown files that can be opened in other editors, with storage choices including a computer, a user’s server, or a hosting provider. Writing tools include live preview, tasks, templates, a daily journal, outlining, Vim mode, comments, and media support for images, PDFs, audio, and video. Pages connect through wiki links, linked mentions, transclusions, tags, and live queries; an object graph is experimental. Lua can add commands, widgets, and automations, while CSS customization is available through Space Style. The server supports accounts, shared spaces, comments, @-mentions, and edits that appear as teammates make them. It works in desktop and mobile browsers, can be installed as a PWA, and supports offline work that syncs on reconnection. SilverBullet is open source, with free plans for personal use, education, and self-hosting. Cloud on PikaPods is $2 a month; Desktop Pro is $50 a year.
