Converts audio files (MP3, WAV, M4A) and video files (MP4) to text using OpenAI's Whisper model deployed as a hosted REST API. The service automatically detects the spoken language from audio content and transcribes across 98+ languages without requiring explicit language specification. Transcription requests are processed asynchronously with real-time progress tracking via dashboard, and files are automatically deleted after 24 hours while transcripts persist indefinitely in user accounts.
Unique: Hosted Whisper API with automatic language detection across 98+ languages and flexible output format support (SRT, VTT, DOCX, PDF) without requiring language specification upfront. Credit-based pricing with transparent cost preview before transcription, and automatic file cleanup after 24 hours while preserving transcripts indefinitely.
vs alternatives: Simpler than self-hosted Whisper (no infrastructure management) and more flexible output formats than Google Cloud Speech-to-Text, but lacks per-language accuracy guarantees and domain-specific fine-tuning options of enterprise solutions like Rev or Otter.ai
Exposes multiple Whisper model size variants (including 'large-v2' and smaller options) as selectable parameters in API requests, allowing users to explicitly choose between accuracy and inference speed. Larger models provide higher accuracy but consume more credits and take longer to process; smaller models process faster with lower credit cost but reduced accuracy. The service claims to transform 10 minutes of audio to text in under a minute using optimized inference, though specific latency benchmarks per model size are not published.
Unique: Exposes Whisper model size selection as a first-class API parameter with transparent credit cost preview before processing, enabling users to optimize for accuracy vs. cost vs. speed per transcription rather than committing to a single model tier.
vs alternatives: More transparent cost preview than AWS Transcribe (which charges per minute regardless of model selection) and more granular model control than Google Cloud Speech-to-Text, but lacks published accuracy benchmarks per model size to guide selection decisions
Optionally identifies and separates speech from multiple speakers in a single audio file, labeling transcript segments with speaker identities (e.g., 'Speaker 1', 'Speaker 2'). Speaker diarization is implemented as an optional feature that increases the credit cost of transcription; the exact credit multiplier or cost formula is not documented. This capability enables meeting transcripts, interview recordings, and multi-speaker content to be transcribed with speaker attribution without manual post-processing.
Unique: Implements speaker diarization as an optional, credit-cost-adjusted feature within the same API call, allowing users to enable/disable per-transcription without separate service calls or preprocessing. Cost impact is shown in preview before processing, enabling cost-aware feature selection.
vs alternatives: Simpler integration than combining Whisper with separate diarization tools (e.g., pyannote.audio) and more transparent cost preview than enterprise services, but lacks published accuracy metrics and no control over speaker labeling format compared to specialized diarization platforms
Generates transcriptions in six distinct output formats (plain text, JSON with timestamps, SRT subtitles, VTT subtitles, DOCX, PDF) from a single audio/video input without requiring separate processing or format conversion steps. The API accepts a 'format' parameter specifying desired output, and the service handles format conversion server-side. Timestamp information is embedded in structured formats (JSON, SRT, VTT) enabling subtitle synchronization with video playback.
Unique: Single API call generates transcription in any of six formats with timestamp synchronization built-in for subtitle formats, eliminating need for separate format conversion tools or post-processing pipelines. Format selection is a simple parameter without additional cost or processing time.
vs alternatives: More format options than basic Whisper API (which outputs JSON only) and simpler than chaining multiple conversion tools, but lacks granular format customization (e.g., SRT styling, DOCX formatting options) available in specialized subtitle editors or document generation services
Implements a credit-based pricing model where each transcription consumes a variable number of credits determined by model size, speaker diarization, and file size. Users receive a cost preview showing exact credit consumption before confirming transcription, enabling informed decisions about feature selection and model size. Credits are purchased in tiered bundles ($5 for 20 credits up to $0.10/credit at 1000+ volume) and never expire, eliminating time-based pressure to consume credits. Free tier provides 5 daily transcription credits without requiring payment.
Unique: Transparent cost preview before transcription with variable credit consumption based on model size and features, enabling users to optimize costs per-request. Volume-based pricing ($0.10/credit at 1000+ volume) and non-expiring credits reduce pressure compared to time-limited subscription models.
vs alternatives: More transparent cost preview than AWS Transcribe (per-minute pricing without feature-level cost breakdown) and more flexible than fixed-tier subscriptions (e.g., Otter.ai monthly plans), but lacks published cost formula making batch estimation difficult compared to per-minute pricing models
Processes transcription requests asynchronously via REST API, returning immediately with a job ID while transcription occurs server-side. Users can monitor transcription progress in real-time via a web dashboard showing processing status, estimated completion time, and final results. This non-blocking approach enables applications to submit multiple transcription requests without waiting for individual completions, and the dashboard provides visibility into queue status and processing metrics.
Unique: Asynchronous transcription with real-time dashboard progress tracking enables non-blocking batch processing and queue visibility without requiring polling or webhook implementation. Job ID returned immediately allows applications to track multiple concurrent transcriptions.
vs alternatives: Simpler than self-hosted Whisper (no queue management needed) and more transparent than AWS Transcribe (dashboard visibility into queue status), but lacks documented webhook support or programmatic status API compared to enterprise services like Rev or Otter.ai
Automatically deletes uploaded audio/video files from the service after 24 hours while preserving transcription text indefinitely in user accounts. This design balances privacy (source files not permanently stored) with usability (transcripts remain accessible for reference, editing, and export). Users must download transcripts or export results within 24 hours if they need to preserve the original file, but can access transcription text from their account indefinitely.
Unique: Automatic 24-hour file deletion with indefinite transcript retention balances privacy (source files not permanently stored) with usability (transcripts accessible long-term). No manual cleanup required; deletion is automatic and transparent.
vs alternatives: More privacy-conscious than cloud services storing audio indefinitely (e.g., Google Cloud Speech-to-Text) and simpler than manual deletion workflows, but less flexible than services offering configurable retention policies (e.g., AWS Transcribe with S3 lifecycle policies)
Accepts remote URLs pointing to audio/video files instead of requiring local file uploads, enabling transcription of content hosted on external servers (e.g., CDNs, cloud storage, streaming platforms). The service downloads the file from the URL, processes transcription, and applies the same 24-hour deletion policy. This capability eliminates the need to download large files locally before uploading, reducing bandwidth and enabling direct transcription of hosted content.
Unique: Accepts remote URLs for direct transcription without requiring local file download, enabling bandwidth-efficient processing of hosted content. Applies same credit-based pricing and output formats as file uploads.
vs alternatives: More convenient than downloading files locally before uploading (reduces bandwidth and latency) and simpler than building custom download pipelines, but lacks support for authenticated URLs or configurable timeout/retry logic compared to enterprise services
Generates code suggestions as developers type by leveraging OpenAI Codex, a large language model trained on public code repositories. The system integrates directly into editor processes (VS Code, JetBrains, Neovim) via language server protocol extensions, streaming partial completions to the editor buffer with latency-optimized inference. Suggestions are ranked by relevance scoring and filtered based on cursor context, file syntax, and surrounding code patterns.
