- No feature tiers
One product. Every feature.
No artificial editions.
Nebulynk does not hold features back for a more expensive edition. Whether your production use is free under the BSL or needs a commercial license never changes the product you can use.
Every product feature
No premium-only feature catalogue.
BYOK, not an AI surcharge
Choose your provider and pay it directly.
Product
From the short message to the next meeting.
Nebulynk joins everyday communication with the moments when text is no longer enough.
Team chat
Public and private channels, direct and group messages, replies, forwards, reactions, files, mentions, pins, reminders and search.
Voice channels
Persistent spaces for spontaneous conversations. Join, speak and leave without scheduling another meeting.
Meetings with AI
Start now or schedule ahead with guests, video, screen sharing, transcription, structured summaries and Ask the Meeting.
Voice channels
Speak spontaneously, without scheduling first.
Voice channels remain visible as fixed spaces in your team. See who is already there and join the conversation directly.
- Persistent voice channels and visible active participants
- Mute, deafen and push-to-talk
- Screen-sharing from the channel context
- Optional Windows helper for global push-to-talk in the browser/PWA
Meetings
Planned meetings, spontaneous calls and guests in one place.
Start a meeting instantly or schedule it with a clear beginning and end. Guests join through an invitation link without access to the rest of the workspace.
- Instant and scheduled meetings
- Guest access through a meeting link
- Video, screen sharing, participant view and meeting chat
- Meeting language and AI artefacts selected per meeting
Meeting intelligence
The meeting ends. The knowledge stays.
Nebulynk can transcribe a meeting and turn its transcript and chat into a structured summary. Decisions, open items and topics remain available for focused follow-up with Ask the Meeting.
- 1Run the meeting
- 2Process the recording and transcript
- 3Receive a summary with key points, decisions and open items
- 4Ask precise follow-up questions later
“Which decision was made for the rollout, and who owns the next step?”
Transcription and summaries require a configured AI provider. Recording and transcription are visible to participants.
BYOK
Your provider. Your key. Your decision.
AI is not an add-on premium module. Administrators configure their own provider access and select models by function. Provider keys remain in the backend and are stored encrypted.
The current product path has primarily been tested with OpenAI models. Provider abstraction already exists. Support for additional providers, OpenAI-compatible APIs and local models is being validated step by step.
Product paths
- Meeting transcription

Self-hosting
Self-hosting without an exotic path.

- Docker-based stack and a dedicated docker-compose.coolify.yml
- PostgreSQL 17, Redis 7 and Garage object storage
- LiveKit and LiveKit Egress for voice, video and meeting recordings
