Detailed Reviews: All 13 Audio-to-Text Apps
NovaScribe — Cheapest Paid Audio-to-Text App
NovaScribe is the cheapest paid audio-to-text app on the market. The $2/mo Starter plan gives you 200 minutes at $0.60/hr — already cheaper than any pay-as-you-go option. The Business plan ($20/mo, 6,000 min) drops to $0.20/hr, making it 50x cheaper than Sonix PAYG and 75x cheaper than Temi. Upload audio in any format (MP3, WAV, M4A, MP4, and 20+ others), get transcripts with speaker labels, timestamps, and AI-generated summaries.
99 languages cover virtually any audio source. The bulk upload feature handles up to 50 files simultaneously — ideal for transcribing an entire podcast season, meeting archive, or research interview set in one batch. AI summaries extract key points, topics, and action items from each recording. The meeting bot joins Zoom, Google Meet, and Microsoft Teams calls automatically.
Plans: $2/mo (200 min), $5/mo (1,000 min), $10/mo (2,500 min), $20/mo (6,000 min). Free trial: 30 minutes one-time.
Pros:
- ✓ Cheapest paid plan at $2/mo ($0.60/hr) — lowest entry price
- ✓ Business plan: $0.20/hr — cheapest per-hour of any subscription
- ✓ 99 languages with automatic detection
- ✓ Bulk upload 50 files at once
- ✓ AI summaries included on all plans
- ✓ Meeting bot for Zoom/Meet/Teams
- ✓ Speaker labels on all plans
Cons:
- ✗ No mobile app (web only)
- ✗ No real-time dictation
- ✗ Smaller brand than Otter.ai or Rev
- ✗ 30-min free trial is one-time only
TurboScribe — Best Free Audio-to-Text App
TurboScribe offers the most generous free tier among audio-to-text apps: 3 files per day, 30 minutes each, no credit card required. That's up to 90 minutes of free transcription daily. Whisper-powered accuracy across 98+ languages. Translation to 134+ languages on all tiers.
The free tier lacks speaker labels and AI summaries. The Unlimited plan ($10/mo annual, $20/mo monthly) removes file caps and adds speaker identification. For users who need AI summaries, NovaScribe ($2–$5/mo) includes them at a lower price point.
Pros:
- ✓ Best free tier: 3 files/day, no credit card
- ✓ Whisper-powered accuracy
- ✓ 98+ languages
- ✓ Unlimited plan available ($10/mo annual)
- ✓ Translation to 134+ languages
Cons:
- ✗ No speaker labels on free tier
- ✗ No AI summaries at any tier
- ✗ No mobile app (web only)
- ✗ No meeting bot
- ✗ 30-min file cap on free tier
Otter.ai — Best for Live Meeting Transcription
Otter.ai is the gold standard for live meeting transcription. Its meeting bot automatically joins Zoom, Google Meet, and Microsoft Teams calls, transcribes in real-time, and generates summaries with action items. Voice profiles learn recurring speakers over time, improving accuracy for repeat meetings. iOS and Android apps let you transcribe on the go.
Free tier (300 min/mo) is generous but has a 30-minute per-conversation cap — problematic for longer meetings. File import is limited to 3 lifetime on free, 10/mo on Pro. Pro plan ($8.33/mo annual) adds 1,200 min/mo, AI summaries, and cross-transcript search.
Pros:
- ✓ Best real-time live transcription
- ✓ Meeting bot for Zoom/Meet/Teams
- ✓ Voice profiles learn speakers
- ✓ 300 min/mo free tier
- ✓ iOS + Android apps
- ✓ Cross-transcript search
Cons:
- ✗ Primarily English — limited multilingual support
- ✗ 30-min per-conversation cap on free
- ✗ File import limited (3 lifetime free)
- ✗ $8.33/mo is 4x more than NovaScribe Starter for file transcription
- ✗ No bulk upload
Notta — Best Mobile Audio-to-Text App
Notta's iOS and Android apps provide the best mobile transcription experience. Open the app, press record, and get a transcript when you stop — recording and transcription happen in one step. 58 languages on the base plan, up to 104 on higher tiers. Real-time translation in 42 languages. Chrome extension for web-based audio.
The free tier (120 min/mo) has a 3-minute live recording cap, making it impractical for most real-world recordings. File uploads work fine within the 120-min limit. Pro plan ($8.25/mo annual) removes the live cap and adds AI summaries and meeting bot integration.
Pros:
- ✓ Best mobile experience (iOS + Android)
- ✓ Record + transcribe in one step
- ✓ 58–104 languages
- ✓ Real-time translation (42 languages)
- ✓ Chrome extension
- ✓ Meeting bot on paid plans
Cons:
- ✗ 3-min live recording cap on free
- ✗ $8.25/mo — 4x more than NovaScribe Starter
- ✗ Billing complaints on review sites
- ✗ No bulk upload
Rev — Best Human Transcription Accuracy
Rev is the only service in this comparison offering professional human transcription. Human transcription ($1.50–$1.99/min) delivers 99%+ accuracy — essential for legal proceedings, published interviews, and compliance-critical recordings. The AI service (free 45 min/mo, or $25.49–$47.99/mo annual) provides standard automated transcription.
Human transcription is expensive: a 1-hour recording costs $90–$119. Use AI transcription for drafts and reserve human transcription for the recordings that truly require near-perfect accuracy. The iOS and Android apps support direct recording and upload.
Pros:
- ✓ Human transcription: 99%+ accuracy
- ✓ iOS + Android apps
- ✓ 45 min/mo free AI transcription
- ✓ Professional speaker attribution
- ✓ Trusted brand in transcription industry
Cons:
- ✗ Human: $90–$119/hr — 450x more than NovaScribe Business
- ✗ AI plans: $25.49/mo — expensive for AI-only transcription
- ✗ 36+ languages (AI) — fewer than NovaScribe (99) or TurboScribe (98+)
- ✗ No AI summaries or meeting bot
- ✗ No bulk upload
Descript — Best for Video/Podcast Creators
Descript is a video and podcast editing suite that includes transcription as a core feature. Its text-based editing paradigm lets you edit audio/video by editing the transcript text — delete a word from the transcript and it disappears from the audio. This makes it unique among transcription tools.
Desktop app only (Mac and Windows). 25 languages. The Hobbyist plan ($16/mo annual) includes 10 hours of transcription per month. If you only need transcription (not video editing), Descript is overbuilt and overpriced compared to dedicated tools like NovaScribe ($2/mo).
Pros:
- ✓ Text-based video/audio editing
- ✓ Edit audio by editing transcript
- ✓ Speaker labels with per-track separation
- ✓ 60 min/mo free
- ✓ Desktop app (Mac/Win)
Cons:
- ✗ $16/mo for transcription — 8x NovaScribe Starter
- ✗ Only 25 languages
- ✗ No mobile app, no web app
- ✗ Overkill if you only need transcripts
- ✗ No meeting bot or bulk upload
Sonix — Pay-As-You-Go with API Access
Sonix offers true pay-as-you-go pricing at $10/hr with no monthly commitment — useful for one-off transcription needs. The Premium plan ($16.50/mo + $5/hr) adds API access, batch uploads, and priority processing. 53+ languages with millisecond-precision timestamps. SOC 2 Type 2 certified for compliance-sensitive industries.
At $10/hr PAYG, Sonix is 50x more expensive per hour than NovaScribe Business ($0.20/hr). The PAYG model only makes sense for truly occasional use — transcribing one or two files per month. For regular use, a subscription tool is dramatically cheaper.
Pros:
- ✓ No subscription required (PAYG option)
- ✓ API access on Premium
- ✓ 53+ languages
- ✓ SOC 2 Type 2 certified
- ✓ Millisecond-precision timestamps
Cons:
- ✗ $10/hr PAYG — 50x NovaScribe Business per hour
- ✗ Web only, no mobile app
- ✗ No AI summaries
- ✗ No meeting bot
- ✗ Expensive for regular use
Happy Scribe — Most Languages + Human Proofreading
Happy Scribe supports over 150 languages — the most of any tool in this comparison. The human proofreading option ($2/min) provides professional-quality results for content that will be published. 15+ export formats (SRT, VTT, STL, XML, FCPXML, EDL) make it strong for media production workflows.
The Basic plan ($8.50/mo annual) includes just 120 minutes — working out to $4.25/hr. That's 21x more expensive per hour than NovaScribe Business. The 10-minute free tier is barely enough to test the tool. Good for specialized language needs; expensive for general English transcription.
Pros:
- ✓ 150+ languages — most in this comparison
- ✓ Human proofreading option ($2/min)
- ✓ 15+ export formats for media workflows
- ✓ Speaker labels on all plans
Cons:
- ✗ $4.25/hr on Basic — 21x NovaScribe Business
- ✗ Only 10 min free trial
- ✗ Web only, no mobile app
- ✗ No AI summaries or meeting bot
Trint — Media and Newsroom Workflow
Trint is built for media professionals who need collaborative transcription workflows. Highlight, tag, and share transcript segments with a team. The Advanced plan offers unlimited transcription. 54 languages. iOS and Android apps for field recording. Real-time collaboration features for newsroom workflows.
Starting at $52/mo, Trint is the most expensive subscription in this comparison. At ~$9.43/hr on the Starter plan, it's 47x more expensive per hour than NovaScribe Business. Only justified for media teams that need the collaborative editing features.
Pros:
- ✓ Collaborative newsroom workflow
- ✓ Unlimited transcription on Advanced
- ✓ iOS + Android apps
- ✓ 54 languages
- ✓ Real-time collaboration
Cons:
- ✗ $52–$80/mo — most expensive subscription here
- ✗ No free tier
- ✗ ~$9.43/hr on Starter
- ✗ Overkill for individual users
- ✗ No AI summaries
Other Tools: Google Docs, MS Word, Transkriptor, Temi
Google Docs Voice Typing — Free Real-Time Dictation (Chrome Only)

Choose if: You need free, unlimited dictation for your own voice. Not suitable for transcribing pre-recorded audio files.
Microsoft Word Transcribe — Free with .edu Microsoft 365

Transkriptor — 100+ Languages, 50% Student Discount

Meeting bot included on paid plans. AI summaries available. The student discount makes it competitive, but NovaScribe Starter ($2/mo) is still cheaper without requiring a student email.
Choose if: You're a student who wants a mobile app with the 50% discount, or you need 100+ languages on mobile. | transkriptor.com/pricing (verified Apr 2, 2026)
Temi — Simple Pay-As-You-Go ($0.25/min, English Only)
Temi is Rev's automated AI service — $0.25/min ($15/hr), no subscription required, English only. iOS and Android apps. Basic speaker labels. No free tier. Useful for a single one-off transcription when you don't want a monthly subscription. At $15/hr, a single 1-hour file costs more than an entire month of NovaScribe Starter ($2/mo for 200 min).
Choose if: You need a one-time English transcription and want to avoid any subscription. For recurring use, any subscription tool is dramatically cheaper. | temi.com/pricing (verified Apr 2, 2026)
Best Free Audio-to-Text Options (Honest Limits)
