Vemio · iOS, Android, Web

Every saved video becomes something you can ask.

Vemio is a multi-user video archive with AI underneath. Paste a link from any major platform; Vemio downloads it, transcribes it, analyzes it and files it. Then you can search it, chat with it and check whether it is telling the truth.

Capture

Save from anywhere.

One paste handles seven platforms. Vemio fetches the media itself, so a saved video stays saved even if the original disappears.

  • Instagram
  • YouTube
  • TikTok
  • X
  • LinkedIn
  • Facebook
  • Vimeo

Also reachable from an iOS Shortcut, so saving is one tap from the share sheet.

Processing

Five states between a link and knowledge.

Every save moves through the same pipeline. YouTube transcripts are fetched with several fallbacks; when none work, the audio is transcribed directly.

  1. PendingLink accepted, queued
  2. DownloadingFetching media from the platform
  3. TranscribingCaptions when available, audio when not
  4. AnalyzingSummary, tags, embeddings
  5. CompletedSearchable, chattable, checkable

Pending, Downloading, Transcribing, Analyzing, Completed. Current stage: Pending.

  1. 01

    Pending

    The URL is validated, attributed to the user and queued.

  2. 02

    Downloading

    Media is fetched from the source platform and stored per user.

  3. 03

    Transcribing

    Platform captions where they exist. For YouTube, multiple fallback paths end in AssemblyAI audio transcription.

  4. 04

    Analyzing

    Gemini 2.5 Flash writes the summary and tags; Gemini embeddings index the content for retrieval. DeepSeek stands in if Gemini is unavailable.

  5. 05

    Completed

    The video appears in the library, in its collections, in search, and is ready for chat and fact-checking.

Retrieval

Ask your library anything.

Questions run against two indexes at once. Semantic retrieval finds meaning; full-text finds exact words. Reciprocal Rank Fusion merges both lists before the model writes an answer that cites its sources.

Insights

Trust, checked.

Insights turns any saved video into an analysis report: key claims verified against the open web and fact-check databases, plus visual and audio deepfake detection.

Key claims
Checkable statements are pulled from the transcript and marked true, false or unverified.
Web verification
SerpAPI and Google Custom Search gather evidence; Google Fact Check API surfaces existing rulings.
Deepfake detection
Reality Defender and BitMind score the visual and audio tracks separately.
Trust score
Every report carries a trust score, an authenticity verdict and the list of sources consulted.

Map

Where your videos are from.

Saved videos can be geocoded and shown on a clustered map, alongside the device's own location.

Product infrastructure

Built to be a business from day one.

Vemio is not a demo. It has plans, quotas, payments in two markets, and the auth model a multi-user product needs.

Plans
Free, Pro and Max, with usage quotas for saves, analyses and chat messages.
Payments
Razorpay for India, Stripe internationally. Webhook-driven billing with a three-day grace period.
Accounts
Email and password with bcrypt, JWT sessions, per-user API keys and fully isolated user data.
Clients
One React Native and Expo codebase with file-based routing, shipping to iOS, Android and web.
