Work

Most of what we make begins as a question.

One product we have spent the most time with, a handful of experiments still finding their shape, and some engineering notes along the way. Start anywhere.

Flagship · our most mature project

Aura

An AI-powered dream journal designed to capture dreams with minimal friction and explore recurring patterns over time.

AI dream journal

  1. 01 · Capture

    Record a dream quickly after waking.

    Speak while the dream is still close. No typing, no structure to fill in.

    Voice-first capture

  2. 02 · Remember

    Build a personal history over time.

    Each dream joins the ones before it, so the journal becomes a place you can return to.

  3. 03 · Explore

    Discover recurring people, places, emotions and symbols.

    Ask questions about your dreams and follow the threads that keep coming back.

  4. 04 · Become aware

    Explore lucid dreaming and awareness-related experiences.

    A gentle step beyond remembering, toward noticing that you are dreaming.

    Lucid experiences

Aura is our most mature project, and it is still growing.

Experiments

Smaller things, explored in the open.

Each of these is at a different stage. Some will grow into products. Others will teach us something and stop.

In development

BrainFocus AI

Sound for focus.

An experimental functional-audio platform exploring layered sound, Web Audio API, DSP and adaptive listening experiences for focus.

  • Functional music
  • Web Audio API
  • DSP
  • Sound layering

Experimental

DualMind

Three priorities, not thirty.

A productivity concept built around reducing cognitive overload. Instead of endless lists, attention rests on three main priorities, and AI helps break larger goals into small steps.

  • Three states
  • Clarity
  • Momentum
  • AI-assisted steps

What do you do?

Experimental

Deep RPG Terminal

A game master in the terminal.

An AI procedural RPG inspired by CRT terminals, retro computing, interactive fiction and generative game mastering.

  • Text adventure
  • Procedural story
  • Retro computing

Today

What stands in the way becomes the way.

Marcus Aurelius, Meditations

In development

Aeterna

A daily Stoic reflection.

A quiet daily experience around Stoic philosophy, reflection, daily cards and contextualized ideas.

In development

Pomoduck

Focus, together.

A playful Pomodoro and focus experiment built around focus sessions, shared study experiences, progression and relaxed motivation.

  • Focus sessions
  • Study rooms
  • Progression

AI and engineering

AI as a material, and as a tool.

We use AI both inside the products we make and in how we build them, choosing different systems for different jobs.

  • Language modelsWriting, summarizing and conversation as raw material.
  • Contextual memorySoftware that remembers what came before.
  • Structured informationTurning loose input into something you can explore.
  • Conversational interfacesTalking instead of tapping, when it helps.
  • Generative mediaImages, sound and narrative made on demand.

Currently exploring with Claude

Among the models we evaluate, Claude is one we spend time with across these areas.

  • Claude Code
  • Reasoning
  • Structured extraction
  • Narrative understanding
  • Conversation
  • Personalization
  • Production API functionality

An engineering experiment

Automated video composition.

A pipeline concept that moves from raw media to a composed video through transcript understanding and matching, with Remotion assembling the result in code.

  1. 1Media
  2. 2Transcript
  3. 3Analysis
  4. 4B-roll
  5. 5Composition
  • Media processing
  • yt-dlp
  • Semantic subtitle analysis
  • LLM-assisted transcript analysis
  • B-roll matching
  • Remotion
  • Programmatic video composition

About

An independent studio, working across AI, creativity and attention.

Aeterna Labs explores how software can support imagination, reflection and focus. Aura is where that work is most developed today. Everything else is us learning in public.

  • Independent

    A small studio with room to follow curiosity instead of a roadmap.

  • Experimental

    We prototype early, learn from what is built, and let ideas earn their way forward.

  • Calm by default

    Software that respects attention, and feels quiet to use.
