Pricing & Value
Pricing is often the first consideration when choosing a dictation app. All three take different approaches: Wispr Flow uses a traditional SaaS subscription, SuperWhisper offers both subscription and lifetime options, and Ottex AI pioneered the BYOK (Bring Your Own Key) model.
With BYOK, you connect your own OpenRouter or API key and pay only for actual usage. For typical users dictating 30-60 minutes per day, this works out to roughly $1-3 per month—a fraction of traditional subscription costs.
Wispr Flow's $15/month subscription includes unlimited dictation but gates advanced privacy features (SOC 2, HIPAA) behind enterprise pricing that can exceed $10,000/month. SuperWhisper's $249 lifetime option seems expensive upfront but pays for itself in about 17 months versus Wispr Flow's subscription.
| Feature | Wispr Flow | SuperWhisper | Ottex AI |
|---|---|---|---|
| Monthly Subscription | $15/mo | $8.49/mo | ~$1-3/mo (usage-based) |
| Annual Cost | $180/year | $84.99/year | ~$12-36/year |
| Lifetime Option | $249 | N/A (pay-per-use) | |
| Free Tier | 2,000 words/week | 15 min Pro trial | Unlimited (BYOK) |
| Hidden Costs | Enterprise for HIPAA | Cloud models extra | None |
“After three months of Wispr Pro, you've already paid more than HyperWhisper's lifetime price. After a year, you've spent nearly four times as much.”— Medium review, December 2025
“Wispr Flow's free tier gives you 2,000 words per week on desktop. That sounds okay until you realize you can hit that in a single productive morning.”— eesel AI Review
Verdict: Best Value
Ottex AI offers the best value for regular users. If you dictate daily, you'll save $150+ per year compared to Wispr Flow while getting cloud-quality transcription.
Transcription Quality
Transcription quality depends on the underlying AI model and how well it handles your accent, vocabulary, and speaking style. Wispr Flow uses proprietary cloud models, SuperWhisper uses OpenAI's Whisper models locally, and Ottex AI lets you choose from multiple providers including Google's Gemini, OpenAI's Whisper, and Anthropic's Claude.
In our testing, cloud-based transcription (Wispr Flow, Ottex AI with Gemini) consistently outperformed local Whisper models for accuracy, especially with technical terminology and non-native accents. However, local processing has zero latency concerns and works without internet.
SuperWhisper offers multiple model sizes (Nano, Fast, Pro, Ultra) with a tradeoff between speed and accuracy. The larger models approach cloud quality but require significant processing time on older hardware.
| Feature | Wispr Flow | SuperWhisper | Ottex AI |
|---|---|---|---|
| AI Models Available | Proprietary (cloud) | Whisper (local/cloud) | Gemini, Whisper, Claude, etc. |
| Technical Vocabulary | |||
| Accent Handling | |||
| Languages Supported | 100+ | 100+ | 100+ |
| Real-time Translation | |||
| Auto Punctuation | |||
| Smart Formatting |
“The accuracy is exceptional, but it depends on two main factors: your microphone quality and the AI model you choose.”— SuperWhisper review
“Wispr Flow's AI engine processes over 500 language patterns per second, delivering 95%+ accuracy even with technical terminology.”— Wispr Flow marketing
Verdict: Best Transcription
Wispr Flow and Ottex AI (with Gemini) tie for best raw accuracy. SuperWhisper wins for offline scenarios where internet isn't available.
Voice Commands & Corrections
Voice commands let you control your dictation naturally without touching the keyboard. The most important is correction commands—the ability to say "scratch that" or "actually" to fix mistakes mid-flow.
Wispr Flow pioneered natural voice corrections and does them well. You can say "scratch that" to delete the last phrase, "actually" followed by a correction, or "delete last sentence." This keeps you in flow without breaking to edit.
SuperWhisper, surprisingly, has no voice correction capability. If you make a mistake, you must stop recording, manually edit, and restart. For long-form dictation, this is a significant productivity hit that many users cite as a dealbreaker.
Ottex AI matches Wispr Flow's correction commands and adds unique inline AI commands. Say "Ottex start translate this to Spanish Ottex end" and the translation happens mid-dictation. No post-processing, no separate step—the AI transforms your speech as you speak.
| Feature | Wispr Flow | SuperWhisper | Ottex AI |
|---|---|---|---|
| "Scratch that" correction | |||
| "Actually [correction]" | |||
| "New line" / "New paragraph" | |||
| Punctuation commands | |||
| Inline AI commands | |||
| Custom voice commands | Via Ottex commands |
“SuperWhisper users appreciate the simple app and offline mode, but complain about the need to manually clean up transcripts.”— Multiple Reddit reviews
“It insists on supplying all of its own punctuation. And there's no way to disable this.”— SuperWhisper App Store review
“VoiceInk: cannot use verbal commands like 'new paragraph'”— Comparison review
Verdict: Best Voice Commands
Ottex AI leads with both correction commands AND unique inline AI commands. Wispr Flow is a close second. SuperWhisper's lack of voice corrections is a significant gap.
AI Features & Shortcuts
Beyond basic transcription, AI features can transform your dictated text—fixing grammar, changing tone, translating, or formatting. The key difference is when this happens: post-processing (after you finish) or inline (during dictation).
Wispr Flow offers "Command Mode" where you dictate, then apply AI transformations afterward. It's a two-step process: dictate first, then trigger the AI to clean up or transform.
SuperWhisper has custom modes with AI prompts that process your dictation. You can create modes for different use cases, but the AI runs after transcription completes—not during.
Ottex AI is unique in offering inline AI commands. Say "Ottex start find a Churchill quote about perseverance Ottex end" and the quote appears inline with your dictation. This "vibe typing" approach—thinking out loud and getting formatted output—is something no other tool offers.
Additionally, Ottex AI has dedicated AI shortcuts: select any text, trigger a shortcut, and apply transformations like Fix Grammar, Translate, Improve Writing, or Make Concise. These work system-wide on any selected text, not just dictated content.
| Feature | Wispr Flow | SuperWhisper | Ottex AI |
|---|---|---|---|
| AI Processing | Post-dictation | Post-dictation | Inline + Post |
| Fix Grammar | Via custom mode | ||
| Translate | |||
| Custom AI Instructions | |||
| AI Shortcuts (on selected text) | |||
| Context-aware formatting | |||
| Filler word removal | Via prompt |
“Spokenly's AI post-processing—grammar/format fixing happens after transcription, not inline.”— Feature comparison
“The one thing Wispr Flow falls short of compared to VoiceInk and SuperWhisper is that you can't do custom prompting to get personalized outputs.”— Dictation app comparison
Verdict: Best AI Features
Ottex AI's inline AI commands and dedicated AI shortcuts make it the clear winner for AI features. No other app lets you transform text mid-dictation.
Privacy & Security
Privacy in voice-to-text apps comes down to one question: where does your audio go? Local processing keeps everything on your device. Cloud processing sends your voice to servers for transcription.
SuperWhisper is the privacy champion—100% offline processing means your voice never leaves your device. This is ideal for sensitive content, legal work, or anyone who simply doesn't want their voice in the cloud.
Wispr Flow is cloud-only and raises significant privacy concerns. Beyond audio processing, Wispr Flow's "Context Awareness" feature captures screenshots of your active window to improve suggestions. For developers working with proprietary code or anyone handling sensitive information, this is a dealbreaker.
Ottex AI takes a middle approach: your audio goes directly to your chosen API provider (OpenRouter, Google, etc.) with zero storage on Ottex servers. You control which provider handles your data, and nothing is retained after processing. It's not fully offline, but it's transparent and gives you control.
Wispr Flow's "Context Awareness" captures screenshots of your screen and sends them to cloud servers. This feature is optional but enabled by default—you can disable it in settings, but many users aren't aware it exists.
| Feature | Wispr Flow | SuperWhisper | Ottex AI |
|---|---|---|---|
| Offline Processing | |||
| Audio Stored on Servers | |||
| Screen Capture | |||
| Choose Your Provider | |||
| SOC 2 Compliance | Enterprise only ($10k+) | N/A (local) | Via provider |
| HIPAA Available | Enterprise only | N/A (local) | Via provider |
“In their quest for 'context awareness,' Wispr Flow captures screenshots of your active window to 'understand' what you are doing...having an app constantly photographing your screen and sending that context to the cloud is a non-starter.”— eesel AI Review
“Privacy protections like SOC 2, ISO 27001, HIPAA are only available with the enterprise tier, which can exceed $10,000 per month.”— eesel AI Review
Verdict: Best Privacy
SuperWhisper wins for maximum privacy (fully offline). Ottex AI is the best cloud option with transparent, zero-retention processing. Wispr Flow's screen capture is concerning.
Performance & Resource Usage
Performance matters for a tool you use constantly. Slow startup, high memory usage, or fans spinning up can all disrupt your workflow.
Wispr Flow is built with Electron (web technologies wrapped as a desktop app) and it shows. Users report around 800MB RAM usage even when idle, 8% CPU consumption in the background, and 8-10 second startup times. On Windows, users report the app freezing and sometimes taking down other apps like VS Code with it.
SuperWhisper is native Swift on Mac, resulting in much lower resource usage (~100MB). However, using larger AI models locally can spike CPU usage significantly during transcription. The tradeoff is between model size (accuracy) and processing speed.
Ottex AI is also native Swift, targeting around 50MB memory footprint. Since transcription happens in the cloud, your CPU stays cool. Startup is near-instant. The only performance consideration is network latency to your chosen API provider.
| Feature | Wispr Flow | SuperWhisper | Ottex AI |
|---|---|---|---|
| Memory Usage (Idle) | ~800 MB | ~100 MB | ~50 MB |
| CPU Usage (Idle) | ~8% | ~0% | ~0% |
| Startup Time | 8-10 seconds | 1-2 seconds | < 1 second |
| Built With | Electron | Native Swift | Native Swift |
| Battery Impact | High | Low-Medium | Low |
| Fan Noise | Often | During transcription | Rare |
“Wispr Flow consumes substantial system resources, with users reporting around 800MB of RAM usage even during idle periods. The tool also suffers from slow startup times, taking 8-10 seconds to initialize.”— eesel AI Review
“On Windows specifically, Wispr Flow felt incredibly heavy. It's an Electron-based app that seems to eat RAM for breakfast...fans spinning up simply because the app was idling in the background.”— Medium review
Verdict: Best Performance
Ottex AI and SuperWhisper tie for best performance—both are native Swift with minimal resource usage. Wispr Flow's Electron architecture is a clear weakness.
