  • Speaker 1 · HiranoWhat we lose most easily is our voices.
  • Speaker 2 · KamiiA voice carries the reasons behind a decision.
  • Speaker 3 · KomomoIt can keep listening, without ever stopping.
  • Speaker 4 · GakuEvery word stays tied to the person who said it.

Hirano

Meetings, planning sessions, casual chats.Every day,we exchange so many words.And what we lose most easily
is our voices.Unlike written words,spoken words carry the speaker’s pauses, their breath, the air in the room —each person’s words, passed back and forth.Most of them vanish without ever being recorded.

A voice carries what a person thinks,and the reasons behind what they decided.Because none of that was kept,the same conversations have been repeated again and again.That’s why
we built Washa.

It can keep listening, without ever stopping.So at last, capturing every voice,all the way through, has become possible.Meetings, small talk, a word that slips out.People’s voices no longer slip away.

Gaku speaking at the round table, the phone in front of him glowing blue

And then it struck us.If the words we speakstay tied to the person who said them,we’ll want to go out and talk with more people.On the street. In shops. With friends.With people we’ve never met.To listen closely, take in their words,and pass them on to the next person.

Where to use it

Interviews, classes, meetings.
Every speaker, in writing.

We leave the round table
and go out to listen.
To people on the street. To discussions in class. To the meeting table.
And to the friends closest to us.

When, where, who said what,
and to whom.
Whose voice, by voiceprint. Where, by GPS.
All kept together on a tag for each moment.

What is Washa

AI transcription with speaker diarization,

Free, with no time limit.

Transcribe an hour-long meeting in one go. Your recordings are never sent to outside servers.

4 common complaints about AI transcription

  1. Complaint 1Free plans hit the limit fast.Caps like “120 minutes a month, 3 minutes per recording” cut long meetings off midway.
  2. Complaint 2Japanese doesn’t come out right.Casual speech and proper nouns get garbled, and fixing them takes time.
  3. Complaint 3You can’t tell who said what.You end up replaying the recording to check who was speaking.
  4. Complaint 4Confidential meetings can’t go to the cloud.The recording would have to be sent to outside servers.

Washa solves
every one of them.

Solution 1

Free, with unlimited transcription time.

No cap on monthly hours or on the length of a single recording. Hour-long meetings, as many as you like.

Solution 2

Highly accurate Japanese transcription, on par with paid services.

Casual speech, hesitations and “uh-huhs” are all captured accurately. Conversations that mix Japanese and English are transcribed as they are.

Also supports English, Mandarin, Cantonese and Korean. On iOS and Mac, German, French, Spanish, Portuguese and Italian are added, for 10 languages in all.

Solution 3

Speaker diarization tells you who said what, automatically.

Each speaker gets their own color. People who have registered their voice are named automatically.

Solution 4

Fully on-device, so recordings never leave.

Transcription and speaker diarization both happen entirely on your own device. Safe for confidential meetings.
