About this listing

Product and access model reviewed from current official sources; workflow and example are editorial suggestions, not a hands-on test.

Monolithos is a personal agent app for macOS, Windows and iOS that keeps what it remembers about you in plain Markdown and YAML files you control, compatible with Obsidian.

Meet Monolithos

Monolithos is a personal agent app for macOS, Windows and iOS that keeps what it remembers about you in plain Markdown and YAML files you control, compatible with Obsidian. It adds AI chat, deep research and presentation tools on top of that memory, and its privacy policy says cloud AI calls may go to Google Gemini, Anthropic Claude or xAI Grok. It is for people who want an assistant with memory they can read and move, and who accept a subscription. The site says fuller always-on agent features are still in development.

A practical workflow

  1. Download the app for your device
  2. Start the 7-day trial, no card needed
  3. Point it at your own notes vault or start a new one
  4. Let it build memory from your materials
  5. Ask it to chat, research or draft with that memory
  6. Review each result before relying on it

Illustrative input

This example describes a task, not a tested output. Adjust the source material and settings to your own situation.

A researcher asks for a summary of their notes vault on one project, then a draft outline using that memory.

Result check: Check that the memory files hold what you expect and verify every fact and citation in AI output before using it.

Access and alternatives

As shown today: a 7-day trial at $0 with no card, then Core $39/month or $349/year and Max $89/month or $859/year, plus a $999 Founder tier limited to 50 seats. No free-forever tier is listed, and the refund page still shows older prices, so check the current pricing page.

Choose another workflow when its emphasis fits better: Mem for AI note-taking with built-in memory; Reflect for notes with AI assistance; AnythingLLM for a private, local-first AI workspace.
