Transcript API
Integrate powerful audio and video transcription capabilities into your application. Support over 200 languages, speaker recognition, and subtitle generation, covering mainstream platforms such as YouTube, TikTok, and Bilibili.
Video Transcriber AI Transcript API turns YouTube, TikTok, files & more into text with speaker diarization, timestamps, 200+ languages, and multi-format export.
Built by Video Transcriber AI, Transcript API turns audio, video, and links from YouTube, TikTok, Instagram and more into structured text through one REST endpoint, with speaker diarization, word-level timestamps, and over 200 languages built in.
Most transcription APIs make you choose one input type — some handle YouTube, others process files, few do both well. Transcript API, built by Video Transcriber AI, unifies them behind one endpoint, with speaker labels, timestamps, and multi-format export included in every response.
Developers often juggle three or four transcription APIs — one for YouTube, another for TikTok and Instagram, a third for file uploads. Transcript API, built by Video Transcriber AI, replaces that stack with one endpoint. Every source, every feature, one integration.
Transcript API accepts over ten input types — YouTube, TikTok, Instagram, Facebook, X, BiliBili, Google Drive, Dropbox, and direct file uploads — all through a single endpoint with one response schema.
Transcript API covers 200+ languages with automatic detection — no need to specify the source language. Mixed-language audio is handled gracefully, so global teams run one pipeline instead of region-specific models.
Speaker diarization is included in every Transcript API response at no extra cost. Each segment is tagged with a speaker label, turning multi-person recordings into readable, attributed dialogue.
Transcript API returns word-level timestamps by default in every response. Search for a phrase and jump to the exact second in the source media, or build interactive transcript players without external tools.
Transcript API outputs plain TXT, SRT, VTT, and full JSON with metadata. Specify the format in your request and get the transcript already structured for your target system — no conversion scripts needed.
Transcript API is a standard REST API with JSON responses and Bearer token auth. Documentation includes code samples in Python, JavaScript, cURL, Go, and Ruby, plus a live playground for testing without writing code.
Sign up, grab your API key from the dashboard, and authenticate with a Bearer token header. Multi-platform transcription, speaker diarization, timestamps, and multi-format export are all included in every request from the start. — multi-platform transcription, speaker diarization, timestamps, and multi-format export — before going live.
Send a POST request to the transcript endpoint with your media URL or file. Use cURL, Python, JavaScript, Go, or Ruby — the API accepts YouTube links, TikTok URLs, cloud storage paths, and direct file uploads through the same request structure.
The JSON response includes the full transcript, speaker-labeled segments, word-level timestamps, and detected language. Drop it into your application logic, convert to SRT or VTT for captions, or store for full-text search.

Analytics Lead
We tried six transcription APIs and Transcript API is the only one that handles YouTube, TikTok, and file uploads through one endpoint. Speaker diarization works great on podcast recordings — it correctly separated overlapping dialogue better than three competitors we benchmarked. Word-level timestamps let us build an interactive transcript player our users love. Processing is fast even during peak hours, and the documentation saved us at least a week of integration time.

Transcript API replaced four different tools we were maintaining for our content platform. One endpoint now covers YouTube, TikTok, Instagram, and file uploads — cutting integration code by about 70%. The 200+ language support let us expand into five new markets without adding infrastructure, and automatic detection means non-technical team members can process videos without picking a language.

Indie Developer
As a solo developer building a video-to-blog tool, Transcript API was exactly what I needed. One POST endpoint accepts YouTube URLs, TikTok links, or file uploads — no per-platform branching in my code. Speaker diarization is included by default with no extra parameters, perfect for multi-guest podcasts. Word-level timestamps let me auto-generate chapter markers. Credit-based pricing covered my entire MVP build, and scaling was smooth.

We chose Transcript API after a three-week evaluation against AssemblyAI, Deepgram, and Google STT. Multi-source capability plus speaker diarization quality on deposition recordings was the deciding factor — it handled three to five speakers with overlapping dialogue better than any competitor. Word-level timestamps are accurate enough for compliance citation without manual checks. Multi-format export to SRT and VTT streamlined our caption review workflow.

Transcript API is the backbone of our educational pipeline — 15,000 video lectures per month from YouTube, BiliBili, and direct uploads in 30-plus countries. Automatic language detection saves four hours of manual tagging daily. Speaker diarization on classroom recordings produces clear transcripts our students search and review. Multi-format TXT/SRT/JSON export from one call feeds search, video player, and analytics simultaneously. Costs dropped while quality improved after switching.

Our social media monitoring tool tracks brand mentions across YouTube, TikTok, Instagram, Facebook, and X. Transcript API replaced five fragile per-platform scrapers with one API call per video. The response is identical whether the source is a TikTok duet or a YouTube replay. Word-level timestamps surface exact mention moments in long videos, and speaker diarization distinguishes creator speech from background conversation — critical for sentiment accuracy.
