runsyour machine or their cloud
installInstall the signed macOS DMG, Windows EXE or Linux package, grant audio/accessibility permissions and choose local, cloud or BYOK processing
enginesLocal Whisper via whisper.cpp; NVIDIA Parakeet and Nemotron via sherpa-onnx; local LLMs via llama.cpp; BYOK OpenAI, Groq, xAI, Mistral, Tinfoil, OpenRouter, Corti, Anthropic/Google and OpenWhispr Cloud
dataNotes and history in local SQLite with recordings/model caches in app directories; optional sync uses OpenWhispr Cloud/Neon PostgreSQL, while cloud or BYOK audio goes to the selected provider
the catch vs Sembly AIIts task and topic extraction and shared-team workflow are less mature than Sembly's managed minutes, and quality depends on chosen models and hardware.
setupMeeting capture needs OS audio permissions and a model download or cloud/API choice; macOS also needs Accessibility and Screen Recording/System Audio permission

installDownload the example Docker Compose and .env, add transcription/text-model credentials or endpoints, set the admin account and run docker compose up -d
enginesASR via self-hosted WhisperX, OpenAI transcription, Mistral Voxtral, AssemblyAI, VibeVoice or custom endpoints; LLMs via any OpenAI-compatible endpoint including OpenRouter, OpenAI, Gemini, LocalAI or Ollama
dataSQLite in the mounted instance directory, audio in mounted uploads or S3-compatible storage, and optional auto-exports such as Markdown and SRT files
the catch vs Sembly AIIt is a self-hosted archive rather than a turnkey meeting bot, so capture and structured minutes depend on the ASR and LLM configuration.
setupDocker is mandatory for the easy path, and the operator must supply API keys or deploy a separate GPU ASR container plus reverse proxy/TLS

the catch vs Sembly AIIt has no shared web workspace or team task integrations, and summary quality depends on the local or BYOK model configured.

last updated 2026-08-29 · no votes, no pay-to-list · just what's real
how to choose a Sembly AI alternative
Easiest to get running
OpenWhispr — a one-click install, no server to maintain.
Most proven
Whisper, with 75,000 GitHub stars — the largest community of the 6, which usually means more answers when something breaks.
Runs on your own machine, no server
Muesli — nothing to host, your data stays on your disk.
Needs real ops to self-host
Speakr is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Sembly AI
- meeting bots, team collaboration, automations, and broad integrations
- calendar auto-join
- reliable speaker diarization
- mobile capture
- team search and sharing
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Sembly AI
People still pay for Sembly AI because a meeting tool must capture every call without surprising anyone, then make the result searchable and shareable across a team. The recurring cost buys audio permissions, model updates, calendar APIs, storage, speaker correction, and sync, not just the visible interface. If none of that applies to you, any pick above saves $204 a year.
