If Wispr Flow's $15/month subscription and cloud round-trip aren't for you, Neuron Flame is the closest thing — same push-to-talk flow, same dictate-into-any-app convenience, but transcribing entirely on your Mac with the option to plug in any LLM you already pay for.

The number-one reason people Google "Wispr Flow alternative" is the recurring cost. $15/month is fine if you're a knowledge worker dictating all day; it's harder to justify for occasional use, students, or anyone with a privacy preference for keeping voice data off third-party servers.
The number-two reason: cloud latency. Wispr Flow's transcription quality is excellent, but it requires a round-trip to their servers. On flaky Wi-Fi or in a coffee shop, you feel it. Neuron Flame's on-device Parakeet V2 model lives on your Apple Neural Engine — it's already loaded by the time you press your hotkey.
The number-three reason: using your own LLM. Wispr Flow runs your transcripts through their AI cleanup. Neuron Flame's AI Enhancement layer is BYO model — pipe transcripts through Gemini, GPT-4o, Claude, your local Ollama install, or even a CLI like the claude command. If you already pay for an LLM, you'll get more value out of it.
Wispr Flow has things Neuron Flame doesn't, and we'd rather tell you up front:
If you have AI Enhancement enabled in Wispr Flow, set up the equivalent in Neuron Flame from the AI Enhancement docs — pick a provider, paste an API key, choose a prompt template. The default prompt is essentially the same: clean grammar, fix obvious mistakes, preserve voice.
Free download. No subscription. No account. Just hold the key and talk.
Download Neuron FlameGenuinely free. No subscription, no license key, no paywall. It's GPL-3 open source — you can read the code, fork it, or distribute it. The only thing we ask is that if you depend on it, you check in occasionally to GitHub for updates.
Comparable for English. Wispr Flow uses a strong proprietary model; Neuron Flame uses Whisper or Parakeet V2 (NVIDIA's English-only model, optimised for the Apple Neural Engine). In our testing Parakeet V2 sits within ~1% word-error-rate of Wispr Flow on clear audio. For other languages, Whisper Large v3 Turbo is the recommended choice.
Not directly — formats differ — but you can copy the words across in a few minutes. Open your Wispr Flow dictionary, then in Neuron Flame use the Dictionary tab to add each word. Future versions may support import.
Yes — and you get to pick the model. AI Enhancement supports Gemini, OpenAI (GPT-4o etc.), Anthropic Claude, Ollama for fully-local cleanup, Groq for fast Whisper Large, and any OpenAI-compatible custom endpoint. The default prompt is set up for the same use case Wispr Flow targets: light grammar fixes, no rewriting.
Neuron Flame is macOS only — we lean into Apple-specific features (Liquid Glass, Apple Neural Engine, App Intents). If your workflow needs Windows, Wispr Flow remains the better choice for that side of the team. For the Mac side, we think we're a strong fit.
