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.

CHECKHC's answer:

CheckHC is the only consumer solution combining AI deepfake detection, official C2PA certification, blockchain registration, and permanent Arweave storage (200+ years) in one click.

• All-in-one: Competitors offer pieces (OpenSea = NFT only, Truepic = C2PA only). CheckHC combines everything.
• Real minting: Unlike OpenSea's "lazy mint," CheckHC actually mints your NFT on Solana immediately.
• GDPR compliance: Unique "Flexible" option allows content deletion for European regulations.
• 90% creator royalties: Higher than Foundation (85%) and SuperRare (85%).
• Affordable: Document certification from €0.09, photo with AI from €2.70, full NFT from $38.50.

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.

CHECKHC's answer:

• Professional photographers protecting their work from theft and AI manipulation
• Digital artists & NFT creators wanting permanent, verified ownership with high royalties
• Content creators & journalists needing proof of authenticity in the deepfake era
• Inventors & entrepreneurs protecting patents and ideas affordably
• Legal professionals & businesses requiring blockchain-based notarization at a fraction of traditional costs

TranscriptFetch's answer

It started with discovering there is no good way to get the text of a video. YouTube’s official Data API will confirm a caption track exists and then refuse to hand it over, because captions.download requires the video owner’s 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.

CHECKHC's answer:

CheckHC was born from a simple observation: in a world flooded with AI-generated content and deepfakes, proving authenticity is becoming impossible.

Founded in France, CheckHC gives creators a simple, affordable way to certify their digital content before it gets stolen or manipulated. We believe every valuable digital content will soon need a "birth certificate" - and CheckHC provides exactly that.

Our mission: make digital authenticity accessible to everyone, not just corporations with enterprise budgets.

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.

CHECKHC's answer:

• Next.js - React framework for frontend
• Solana - Fast, low-cost blockchain for NFT minting
• Arweave - Permanent storage (200+ years guaranteed)
• Custom AI model - Deepfake detection
• C2PA standard - Coalition for Content Provenance and Authenticity certification

CHECKHC's answer:

CheckHC just launched publicly in January 2026. We're currently onboarding our first customers:

• Independent photographers and digital artists
• Small creative agencies
• Content verification early adopters

We're offering special early-adopter pricing for professionals who want to be among the first to protect their digital assets.

TranscriptFetch's answer

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 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.

CHECKHC's answer:

CheckHC is the only platform that combines in a single click:

• AI deepfake detection - Verify your content is authentic
• C2PA certification - Official industry standard (we're a member)
• Solana blockchain - Immutable proof of ownership
• Arweave storage - 200+ years permanent preservation
• GDPR compliance option - Unique "Flexible" NFT with deletion rights

No competitor offers all of this. OpenSea has no AI, no C2PA, no permanent storage. Truepic is B2B only at $$$. Reality Defender has no blockchain, no NFT.

CheckHC = digital birth certificate for your creations, from €0.09.
