Reliable YouTube transcripts through one API

Visit capslane.com ↗Alternativestop 2% of September 2026

What it does

Capslane gives developers a stable API for YouTube transcripts. It returns native captions when available and automatically generates a timestamped transcript when they are missing. Get plain text or structured segments, choose a language, manage API keys, inspect usage, and connect through JavaScript, Python, MCP, or n8n. Start with 50 free requests each month.

Extract YouTube captions or generate timestamped transcripts through one reliable API. Start with 50 free requests each month.

Retrieve captions from public YouTube videos or generate a transcript when captions are missing. One API with timestamped results, explicit jobs and workspace quotas. Gems, our video product at Webba, uses Capslane for transcript analysis and footage search. Its migration kept timestamped segments and added generated fallback for videos without captions. Read the Gems implementation or inspect the dated 200-video benchmark and its limits . Create an API key in the dashboard, send a video URL and receive the transcript as text or timestamped segments. curl 'https://capslane.com/v1/transcript?url=VIDEO_ID' \ -H 'x-api-key: vxl_live_...' 200 OK { "lang": "en", "content": [ { "text": "...",…from capslane.com

  • Running 104GB Qwen3.8-Flash-Next on 48GB Mac with at ~12 tok/s▲239

    I built slotstream, a way to run Qwen3.8-Flash-Next 4-bit on a low-memory mac starting from 16GB, a 125B parameter model that would need 100GB+ memory/RAM, thanks to expert-offloading/ssd-streaming. Easy to install/update, and mac-native using MLX and Swift. It ships with auto-mode, which makes a good tradeoff between memory usage and speed. I'll be implementing and porting the MTP module for speculative decoding next Local models really are the future of computing!
