TranscriptFetch is one API for getting text out of video and web content.
Send a URL from YouTube, TikTok, Instagram, X or Facebook and get back clean, timestamped text. Send any web page and get clean Markdown. One endpoint, one response shape, one API key.
Most short-form video has no caption track to download. TikTok's auto-captions are opt-in per upload, Instagram never publishes a downloadable track, and a large share of captions on both platforms are burned into the video frames where no parser can read them.
When there is no caption track, TranscriptFetch transcribes the audio instead. Same endpoint, same response, so your code never branches on which method produced the text.

One credit per successful response. Failed, blocked and empty results are never charged, which matters on short-form video where a meaningful share of any batch is music with no speech in it.

TranscriptFetch's answer:
Most short-form video has no caption track to download. TikTokโs auto-captions are opt-in per upload, Instagram never publishes a downloadable track, and many captions on both are burned into the video frames where no parser can read them. TranscriptFetch transcribes the audio when no caption track exists, on the same endpoint, with the same response shape. Your code never branches on which method produced the text. It also covers YouTube, TikTok, Instagram, X and Facebook plus any web page as clean Markdown, so a pipeline spanning several sources is one integration rather than five.
TranscriptFetch's answer:
Three reasons. Coverage: one API key and one response shape across five video platforms and the open web, instead of stitching together a library per platform. Reliability: requests run through rotating infrastructure, so code that works locally keeps working from a server, which is where most open-source approaches break. Billing that matches reality: one credit per successful response, with failed, blocked and empty results never charged. That last point matters on short-form video, where a meaningful share of any batch is music with no speech in it. There is also an MCP server, so AI agents can fetch transcripts as a tool without a custom integration.
TranscriptFetch's answer:
Developers and technical teams building on video and web content. The common cases are RAG and retrieval pipelines that need video as text, AI agents that need to read a link mid-conversation, content teams repurposing short-form video at scale, and media monitoring and research tools. It is an API first, so the buyer is usually the person writing the integration rather than an end user. The free browser tools exist for one-off transcripts and for evaluating output quality before writing any code.
TranscriptFetch's answer:
It started with discovering there is no good way to get the text of a video. YouTubeโs official Data API will confirm a caption track exists and then refuse to hand it over, because captions.download requires the video ownerโs OAuth token. The popular open-source libraries work until you deploy them, at which point platforms start refusing datacenter IPs. And YouTube is the easy case: TikTok and Instagram publish no caption file at all. Every workaround solved one platform, worked locally, and broke in production. TranscriptFetch is the version that handles the failure cases as first-class behaviour rather than edge cases.
TranscriptFetch's answer:
Next.js with TypeScript and Tailwind on the front end and API layer, Clerk for auth with SHA-256 hashed API keys, Neon Postgres with Drizzle ORM, Redis for caching, and Stripe for billing. The extraction layer is a Python and FastAPI service. Speech-to-text uses Whisper-class models. The MCP server is published in the official Model Context Protocol registry with a DNS-verified namespace.

I don't know of any that use a more powerful model. The only alternatives I know of that use GPT-3, and that also work somewhat similarly to AI Dungeon, are ShortlyAI and Hyperwrite. Both have free trials, but both also use OpenAI's awful filter that blocks pretty much any remotely mature content. You probably already know of NovelAI and HoloAI, and although neither one uses a model as large as what Dragon-21... Source: over 4 years ago
Shortlyai.com was the AI service I was using previously. Very basic. You just input a prompt and tell it to write for you. Worked great for patterns and lists, not so much if you wanted to shape a story. Source: almost 5 years ago
Dragon uses the 175B GPT-3 Davinci model. Philosopher AI and EndlessVN use the same model, though they both work significantly differently from AI Dungeon. EndlessVN is also in closed alpha at the moment; if you didn't sign up for the closed alpha, you'll have to wait for it to become public. HyperWrite and ShortlyAI also exist, but I'm unsure whether they use GPT-3 Davinci, or a weaker GPT-3 model. They also use... Source: almost 5 years ago
There are plenty of free alternatives. Write With Transformer exists, is free, and has a few AI models to choose from. You can try the base GPT-J 6B model on EleutherAI's website, or through the KoboldAI Google Colab. Clover Edition exists, and has multiple AI models to choose from. GPT-Neo Dungeon exists, and uses GPT-Neo, hence the name. Open CYOAI and AI Dungeon 2 Unleashed also exist. GodAI exists as well,... Source: almost 5 years ago
ShortlyAI uses GPT-3, and offers a free trial. After the free trial, a subscription is required. Though, similarly to Hyperwrite, some content is disallowed. Source: almost 5 years ago
