Files on disk are the source of truth. Delete its index and it rebuilds.

Markdown is canonical. Properties live in front matter you can read anywhere.

You know your ontology, but your agent doesn't. Terra links the people, places and sources for them.

Local first. Search, the index and the ontology all run on your Mac.

Views

Your library.
Infinitely customizable views.

Every folder becomes a database: a library, calendar, timeline or burndown, or a table, board, map, graph or canvas. Tailor each view to your own preference. Look at data a different way.

Library

01
Cards, lists, graphs and tables

PDFs, spreadsheets, images, web pages and notes.

Calendar

02
Agendas and calendars

Assign events, tasks and files a date.

Timeline

03
Gantt and dependencies

Create blocking relationships and manage deliverables.

Burndown

04
Tasks and queue

Remaining work, prioritize and triage.

Markdown as data.

PDFs retain highlights in structured markdown. Meetings, people and events, sheets and photos get properties that fit into your databases, alonside your notes.

Features

With Terra
Work that moves you.

We’re here to get work done. Terra is built to be a one-stop shop. You can run code, craft spreadsheets, cite sources, and browse the web without context switching.

01

Run code in Terra

Terra supports runnable Python and R cells. Tables and charts print right under the code.

PythonRun cell
import pandas as pddf = pd.read_csv("travel.csv")df.groupby("region").days \  .sum().plot.barh()
⌘↩ runs the cell

First-class Spreadsheets

Open .xlsx and .csv files with live formulas, tabs and charts.

Type /sheet to add into any note.

Reference engine

Type [@, pick a source, and a APA/MLA/Chicago references list builds at the end of the note.

The Transformer drops recurrence and relies on attention alone [@vas(Vaswani et al., 2017)

Ask with your own model

Pick a local or cloud model. Terra uses the ontology — the people, places and sources — to provide clear answers fast.

Use a classifer to structure incoming data automatically.

With the Terra MCP ask your model to craft any view, function or arrangement.

Why not the others

Why not Obsidian, Notion or Craft?
Your library, your models, your way.

Terra knows your files are yours and yours alone. We will will never store your data or force you to use our LLM models. We found other products to lack features that should be first class citizens.

How pricing works

Your AI, your bill
Use your own API keys, or run models locally with Ollama at no extra cost.
Stop anytime
If your plan ends, Terra turns read-only. Your files stay on your disk, readable in any editor.
Works offline
Terra checks your licence at launch and every 12 hours. Offline, it keeps working for 14 days, then turns read-only until it can check again.

One account, up to 5 Macs. Read-only if your plan ends: you can still open, search and print your notes, and copy the files. Needs macOS 14.0 or later and a Terra account.
