Constella automatically surfaces contradictions and insights before it's too late in your research journey.

May 18, 2026
Meta-analysis across 14 dose-response trials: low-dose mindfulness (≤10 min/day) shows comparable or superior anxiety outcomes to high-dose protocols. Higher doses correlate with increased dropout.
# AI assistant knowledge management todo
May 16, 2026
Pilot data from our trial suggests the high-dose mindfulness arm reduced anxiety more than the low-dose arm at week 8. The effect is strongest among participants with prior meditation experience and tracks self-reported adherence, though our adherence measure is a single item. Reviewer #2 flagged this in v2. Plan to revisit the dose framing in the discussion before submitting v3 of the manuscript.

How it works

From scattered notes to a thinking partner

Stop hunting through tabs, folders, and forgotten PDFs. Constella maps your research, surfaces the themes, and drafts what you already know.

Three things happen the moment your research lands on the canvas

Everything you have collected, finally working together. Bring it in once and Constella does the rest.

See it in action
All your sources flowing into one shared canvas

Bring everything onto one canvas

PDFs, notes, papers, Notion pages, Gmail threads, the folder of Markdown you keep forgetting about. Drop it all in. Stella now has the full picture of your research.

Knowledge graph clustering related notes and drawing connections between them

Watch your ideas cluster and connect themselves

Auto-Clustering groups related notes into the themes you have actually been writing about. Auto-Connections draws the links between them. The shape of your thinking, visible at last.

Stella turning your notes into a structured project

Ask Stella to build the project for you

Type what you want to explore. The Project Builder gathers your sources, drafts the structure, and hands you a canvas already mid-thought. The blank page, finally gone.

Workflow

Set up. Drop in. Start thinking.

From empty page to working canvas in under a minute. Built for researchers who already have too many tabs open.

Plan, search

Bring in what you already have

Notion, Drive, Gmail, PDFs, the folder of notes you keep meaning to organize. Plug it all in once and Constella holds the full library for you.

Scale

Loved by writers, researchers & thinkers

From students to founders, Constella has become the go-to canvas for people who think in connections, not folders.

Constella has become my go to app for notes, PKM and decision support. Its advanced AI features provide me with insights that I can't get elsewhere.The visual graphical and interactive interface works the way I work. Constella is a home run in the AI/Note/PKM market.
