Sound familiar?

If you've felt any of these frustrations, you're not alone. Journalists, students, writers, professionals, and anyone tired of cloud transcription caps deal with this every day.

1

Otter.ai, Rev.com, Trint, and other voice-to-text apps are all cloud-based. They upload your audio to their servers for processing, then count minutes against your free tier — usually capped at 300 per month. Past that, you pay $10-30/month for features that could run on your phone.

2

Cloud transcription services fail the moment your internet drops. They also fail on long recordings because the upload takes forever on cellular or hotel Wi-Fi. And they fail privacy-sensitive use cases: medical, legal, journalism, therapy sessions.

3

Apple's built-in Dictation feature works but doesn't save the transcripts anywhere useful — they're gone the moment you tap away from the text field. There's no searchable library of everything you dictated last month.

Here's how Nemos helps

Nemos was built to solve exactly these problems — automatically.

✓

Nemos uses Apple's Foundation Models API for on-device speech-to-text. The entire transcription pipeline runs locally on your iPhone's Neural Engine — no audio upload, no minute cap, no server dependency, no subscription required for unlimited use.

✓

Every transcription is automatically saved into your Nemos library with an AI-generated title based on content. The full transcript is searchable by any word, and you can jump to any timestamp in the audio.

✓

Works offline indefinitely. Record a two-hour interview in airplane mode and the full transcription is ready within 3-4 minutes on an iPhone 15 Pro. No internet required.

"I'm a journalist who records 4-6 hours of interviews per week. Otter charged me $20/month and still capped my free tier. Nemos is free and unlimited, and the transcripts are actually better because Foundation Models handle accents more gracefully."

Frequently Asked Questions

What is the best free voice to text app for iPhone?+
Nemos is the best free voice to text app for iPhone because it offers unlimited on-device transcription via Apple Intelligence. Otter.ai, Rev, Trint, and Happy Scribe all charge after 300-600 minutes per month because they run transcription in the cloud. Nemos runs on your iPhone's Neural Engine, so there are no per-user costs to recover — the free tier is genuinely unlimited.
Does Nemos speech-to-text work offline?+
Yes. Unlike every cloud transcription service, Nemos transcribes audio on-device using Apple's Foundation Models API. Record in airplane mode, a subway, a rural area, or an international flight — transcription works identically whether you're online or offline.
How accurate is on-device speech to text on iPhone?+
For clear English speech in quiet environments, Apple's on-device speech recognition combined with Foundation Models post-processing is 95%+ accurate. Accuracy drops for heavy accents, background noise, or multiple speakers overlapping — similar to any transcription service. The main advantage over cloud services is that there's no network latency (real-time transcription) and no privacy tradeoff.
Is Nemos better than Otter.ai or Rev?+
For most personal and professional use cases, yes. Otter.ai and Rev are cloud-based with monthly minute caps on the free tier ($16-30/month for paid). Nemos is free with unlimited on-device transcription. The tradeoff is that Otter has real-time collaboration features that Nemos doesn't, so for team meeting transcription with shared editing, Otter still wins. For individual use, Nemos wins on cost, privacy, and offline capability.
