Subanana

Subanana is an AI-powered spoken-word platform built by Datax AI Solutions that converts audio and video into subtitles, transcripts, meeting notes, and live captions across 95+ languages. The platform claims 98% average word accuracy across everything it transcribes, including code-switched speech, and is marketed as being trusted by 200K+ users. It covers four core workflows — subtitling and translation, interview and research transcription, meeting capture, and live event captioning — all from a single editor.

What It Is

Subanana is a web-based AI transcription and subtitling service that takes audio or video input (uploaded files, live streams, or meeting recordings) and produces publishable deliverables: SRT, VTT, FCPXML, DOCX, XLSX, Markdown, and burned-in MP4 up to 4K. It is designed for content creators, UX researchers, journalists, educators, event organizers, and enterprise teams who need accurate, multilingual spoken-word output without manual transcription. The platform positions itself around accuracy at the deliverable level — meaning the output is meant to pass QC and be published directly, not just serve as a rough draft.

Core Workflow Modules

Subanana organizes its product into four distinct job types:

• Subtitles & Translation: Dual ASR engines run per language pair with millisecond timecodes. A glossary enforcement system locks brand terms before translation. Exports include SRT, VTT, FCPXML, and burned-in MP4 with 37 caption style presets.
• Interview & Research: Word-level speaker diarization separates overlapping voices, assigns named speakers, and surfaces quotable segments with timecodes. Outputs include DOCX, XLSX, and bilingual ZIP archives.
• Meetings & Notetaker: A calendar-aware notetaker bot joins Google Meet, Zoom, or Microsoft Teams. A no-bot Chrome extension captures tab audio when a visible bot is not appropriate. Both modes produce decisions, action items, chapters, and a searchable transcript.
• Live Captions & Events: Pre-loaded speaker names and glossary terms feed a live captioning engine with under 2-second latency across up to 12 languages simultaneously. Attendees can follow captions on their own phones via QR code.

Language and Translation Architecture

The platform's stated differentiator in translation is context retention across the full transcript rather than line-by-line processing. The homepage demonstrates this with a Spanish-to-English example where pronoun gender is preserved correctly across multiple sentences — a failure mode it attributes to line-by-line tools like Gemini and ChatGPT. Subanana claims particular depth in Cantonese (including code-switched Cantonese/Mandarin), Traditional Chinese, and other Asian languages alongside the major European languages. The engine is described as running dual ASR per language pair with silence recovery and millisecond-level alignment.

Integrations and Export Ecosystem

Subanana connects to a range of sources and downstream tools:

• Input sources: YouTube links, Instagram links, Google Meet, Zoom, Microsoft Teams, OBS, and a browser-based recorder
• Calendar integrations: Google Calendar, Microsoft Outlook (for meeting bot scheduling)
• Export formats: SRT, VTT, ASS, TTML, FCPXML, TXT, DOCX, XLSX, Markdown, burned-in MP4
• Other integrations shown: ProPresenter (for live event display), Chrome Web Store (extension), Facebook, Instagram Reels

Target Audiences

The platform explicitly targets several distinct user groups: video creators, online course producers, podcast teams, product managers, sales teams, schools, NGOs, UX researchers, academics, and oral historians. The homepage also displays logos of organizations the vendor describes as trusting the platform, including Google, Deloitte, Amazon, Shopify, Figma, and others — these are vendor-published claims and should be treated as such.

Deployment Model

Subanana is a cloud-based web application accessed at plus.subanana.com, with a Chrome extension available for no-bot meeting capture. There is no desktop app or self-hosted option mentioned. The platform is operated by Datax AI Solutions and is available without a credit card to start.
