Cosmas

Features

Everything Cosmas does

The desktop app in detail, with what the web version can and can’t do yet.

Recordings library: Every clip and recording in one place, grouped by game and evening.

Recordings library

Every clip and recording in one place, grouped by game and evening.

  • Finds Medal folders on its own (Videos\Medal, X:\Medal); add OBS, ShadowPlay or any other folder.
  • Medal clip titles, games and hotkey bookmarks are read automatically; Medal’s own database is never written to.
  • Filters by game, server, type, album, tag and character, and search in what was said once a video is transcribed.
  • Multi-select with Ctrl/Shift and drag clips onto an album or an event.
Multi-track player: Hear exactly the part you need: the game, Discord or yourself.

Multi-track player

Hear exactly the part you need: the game, Discord or yourself.

  • Game, Discord and microphone play at once as separate tracks; mute, solo or set each one’s volume.
  • Track presets (Ctrl+Shift+1…9) and default tracks for every game.
  • Frame preview on hover and a loudness waveform for each track under the seek bar.
  • Resumes where you stopped, pops out into its own window and decodes video on the GPU.
Moments and clips: Bookmarks and segments from all your videos, attached to events and characters.

Moments and clips

Bookmarks and segments from all your videos, attached to events and characters.

  • B marks a moment, Shift+B a segment, P drops a moment straight into an event.
  • Medal hotkey bookmarks appear on their own; automatic game moments like “Double Kill” are hidden.
  • I / O set a clip, then export it to MP4 with all audio tracks.
  • S takes a snapshot for an event, a cropped picture or a character portrait.
Events and journal: The story itself: what happened, when, where and who was there.

Events and journal

The story itself: what happened, when, where and who was there.

  • A tree of events and sub-events with real and in-game dates, a place, tags and characters with roles.
  • A rich-text write-up with @ mentions, and a journal of dated entries with attachments.
  • Attached recordings with smart suggestions; “Suggest from recordings” groups unsorted videos into game nights.
Characters, factions and places: A database of your world that keeps track of who is who.

Characters, factions and places

A database of your world that keeps track of who is who.

  • Character profiles with portrait, status (alive, dead, missing), player, biography and where they appear.
  • Relationships that follow gender (father/mother ↔ son/daughter, liege ↔ vassal …) with notes.
  • Factions and houses with coats of arms and members with roles; places with owners and parent places; servers with the period you played there.
  • Bulk edits with Ctrl/Shift + click.
Timeline: The whole chronicle in order, across servers and evenings.

Timeline

The whole chronicle in order, across servers and evenings.

  • Four views: a chronicle, a zoomable Gantt timeline, a calendar and character lanes.
  • Moments show as flags; selecting a server filters the timeline like everything else.
AI chronicler: After a transcript, a stronger text model reads the evening in blocks with a running memory of the plot and what your database already knows.

AI chronicler

After a transcript, a stronger text model reads the evening in blocks with a running memory of the plot and what your database already knows.

  • Writes chapters and a summary of the evening, and saves mentions to characters, places and factions.
  • Suggests new events, characters, places and factions; accept one with a click and it links back to the right second of the video.
Where the AI runs: Cosmas looks at your graphics card, memory and processor and recommends what your PC can handle.

Where the AI runs

Cosmas looks at your graphics card, memory and processor and recommends what your PC can handle.

  • On this PC: Whisper for speech, Ollama for vision and the chronicle. Installed and downloaded with one click. Nothing leaves your PC.
  • Paid service: Groq, Anthropic Claude, Google Gemini, OpenAI or OpenRouter. You pay them directly; Cosmas shows the estimated cost per hour of recording and what you spent in the last 30 days.
  • API keys are stored encrypted in Windows Credential Manager. You can mix: speech locally, the chronicle through a service.

AI that works for you

Optional and off until you choose where it runs. Free on your own PC, or through a paid service you pick.

  • Transcripts

    Each audio track separately (you, the game, Discord), in the background, one video after another. Search in what was said and turn on subtitles in the player.

  • Image descriptions

    Frames are described mostly during conversations. The model reads name tags above characters and links them to your characters and players.

  • Faces and appearance

    Faces found in conversations can become portraits, and characters are recognised by clothing and hair across a session.

  • Stays out of your game

    The queue pauses while you play a game and continues afterwards, and picks up where it stopped after a restart.

And also

  • Pigeon post

    Letters between characters: paste messages copied from Discord, import them through a bot from a channel or from your Discord data export, or write them by hand.

  • Discord players

    Link players to Discord by ID to get their name and avatar, or load a whole server’s members with your own bot.

  • Gallery

    Every screenshot and snapshot from your videos in one place, each with “Play video from …”.

  • Look and feel

    Seven themes, accent colour, interface size, rounding, font and animations, player beside or above the content.

  • Game artwork

    Banners and icons for your games, with total recorded time per game.

  • Safe with your files

    Medal’s database is read-only for Cosmas; deleting a video moves it to the Recycle Bin.

Desktop or web

One chronicle, two ways in. The desktop app does the heavy work on your PC; the web version needs no install. They sync when you sign in.

The web version is an early alpha. It shares your chronicle with the desktop app but doesn’t do the heavy work: no multi-track audio, MP4 export, AI or Medal details yet.

Cosmas on Discord

The community RP bot reads your characters straight from Cosmas, so there is one sheet to keep up to date.

  1. Use on Discord

    Switch it on for a character and play it in the community’s Discord worlds: /ic messages in its name, its inventory and scenes.

  2. Character cards

    Characters shared by link or published get a card in the community’s character forum. It updates when you edit the character.

  3. The /kronika command

    Search the public chronicle from any channel and post a record as a card with a link.

Public chronicle and lore registry

What you publish carries your name and your terms.

  • Authorship

    Each published record shows its author and the date it was first published, as proof of who came up with it.

  • Licences

    All rights reserved, use with permission, CC BY, CC BY-NC or CC0. You choose per record.

  • Permission requests

    “I want to use this” notifies the author, and a log shows on which servers the lore was used.

  • Wiki and moderation

    Revision history with rollback, edit suggestions, discussion, and reports that go to the moderators.
