Our verdict
Saydi suits people who need live translation of meetings or conversations, with a Free plan to try and Pro at $9.99/month. Trade-offs: usage is metered in credits, the stores' "on-device" privacy claim conflicts with the privacy policy, and the product is new (released December 2025).
Best for: People travelling or meeting partners who speak another language
Skip it if: Anyone who needs a firm guarantee that audio never leaves the device
Pros
- Two-way, one-way and transcribe modes, with 60+ languages per the developer.
- Apps for iOS, Android and macOS plus Chrome/Edge extensions, with Meet, Zoom and Teams integrations.
- A Free plan with no card required, and pay-as-you-go credits that do not expire.
Cons
- App Store and Google Play descriptions say audio is processed on-device, while the privacy policy says audio is sent to Deepgram and Google.
- Self-declared data disclosures disagree: Google Play says data isn't encrypted while the policy cites HTTPS/WSS, and the App Store label lists usage data used for tracking.

Experience & key features
Saydi is an AI voice translation app with three modes: two-way translation, one-way translation and transcription. Its site says it detects languages automatically, labels speakers and covers 60+ languages. The App Store lists Notionis Technologies Pte. Ltd. (Singapore) as developer, while the terms of service are issued by SotaX Company Limited, which the site footer names as Saydi's operator in Vietnam.
Beyond live translation, Saydi offers AI summaries, an in-session chat, AI context (uploaded documents, custom terms) and a Chrome extension for Meet, Zoom and Teams. Platforms are iOS, Android, macOS and Chrome/Edge extensions per its download page. Version 3.0 on the App Store (15 June 2026) added two-way voice translation and screen-audio translation.
Pricing is credit-based: voice-to-text costs 45 credits/hour, basic voice-to-voice 200 and premium 400. Free includes about 100 credits in the first month; Pro is $9.99/month for 1,000 credits; Teams, a business plan, is $19.99 per seat per month. Pay-as-you-go credits cost $2 per 200 and never expire, and the App Store also sells 3-, 4- and 7-day Trip Packs ($4.99–$7.99). Business and Event plans for organisations are quoted on request. The pricing page lists USD only, so no VND figure is given.
On privacy, the policy and the store descriptions do not match: the policy says audio passes through Deepgram and Google, while the stores say on-device processing. A search found no credible reports of breaches, lawsuits or complaints about Saydi. Anyone translating sensitive content should read the policy first. For quick translation, Google Translate, DeepL and Microsoft Translator are alternatives; for meeting transcription, Otter.ai.

Cancellation & refunds
Per Saydi's terms: a 100% refund for a technical failure on Saydi's side it cannot fix (request within 14 days), for payments where access was not granted, and for duplicate charges (both within 30 days). Email [email protected] with the subject [Refund] and the transaction ID; Saydi replies within 3 business days and refunds reach the original payment method in 7–30 business days.
Privacy
The privacy policy (updated December 2025) says audio is streamed and processed in real time and Saydi does not permanently store raw recordings. Audio goes to Deepgram (speech-to-text) and Google (translation); the policy says neither keeps the audio or uses it for model training. Transcripts are kept on Saydi's servers only if the user saves a session, and can be deleted or exported at any time. The policy says connections are encrypted (HTTPS/WSS). However, the App Store and Google Play descriptions say audio is processed on-device, the developer's own Google Play Data safety form says data isn't encrypted, and the self-declared App Store privacy label lists usage data as used to track. These statements conflict, so anyone handling sensitive content should rely on the policy and ask the developer.

Frequently asked questions
Is Saydi free?
Yes, there is a Free plan with no card: about 2 hours 13 minutes of voice-to-text in the first month, 10 minutes per session. For more, buy credits ($2 per 200) or Pro at $9.99/month.
