Penzu is a private online diary. MySamantha is a personal workspace with a private journal inside.
Penzu has focused on private, personal diary writing for years, and that simplicity is part of its appeal. MySamantha keeps the journal private too, and places it beside Notes, Tasks, Email and Calendar with an optional assistant.
Choose Penzu if…
You want a dedicated, distraction-free diary and prefer a tool that does exactly one thing.
Choose MySamantha if…
You want journaling with voice entries and photos in the same workspace as your tasks, notes, inbox and calendar, with the option to keep AI out of it completely.
The architectural difference
Penzu is a standalone diary. MySamantha is a connected workspace where the journal is one locked, private surface among the tools you use every day.
Let’s make reflection a natural part of your day.
Samantha remembers for you
Ask her for the entry about last week, and she can find it for you.
Your days, in one glance
A clean calendar view that shows every entry, mood, and moment without digging.
Lock it and move on.
Your journal stays protected with your device lock, private and yours.
Capture the moment
Attach photos, screenshots, or memories.
A private journal, not a training set.
Write or speak, attach photographs, look back by day. Samantha only reads a journal entry when you ask her to.
