TL;DR
Get the important facts in seconds.
Highlights key points, recommended questions to ask, and possible implications of what the text means.
TTS (Text-to-Speech)

Listen to newsletters, articles, and emails while driving, on the bus, at the gym, or between meetings.

Frequently Asked Questions
How does this work exactly?
You forward any article, newsletter, or email to one of our magic addresses and receive a TLDR summary or a voice recording in your inbox.
What can I send to you?
Most text-based content works:
- Newsletters
- Articles and blog posts
- Reports and internal updates
- Long email threads
- PDF attachments (text extracted automatically)
- Markdown (.md) files
The cleaner the text, the better the summary and audio quality. Very short content (a few sentences) may not produce a useful result.
Do I need to install an app?
No. Just send your first email to tldr@ottersay.com or a voice address and your free account is created automatically. No sign-up form, no password, no credit card. Your free credits are included from the start.
Is my data safe?
We process your email on the fly and do not store content permanently after delivery. Voice recordings and summaries are generated per request and are not used to train AI models. Your email content is passed to third-party AI providers (Anthropic for summaries, Amazon Polly or similar for audio) under Standard Contractual Clauses as required by GDPR. We don’t sell your data. Full details are in our Privacy Policy.
Which languages do you support?
The summary service works in any language – you get the summary back in the same language as your source text. Audio is currently English only – US and UK accents available for audio. More languages are on the roadmap. Let us know which one you’re missing using the contact form.
Can I use my own voice or clone my voice?
Not yet, but it’s on the roadmap. Let us know if you’re missing this feature using the contact form.
