User reviews

Good

it has its hiccups a few times it doesn't catch my talking and that's a bit irritating because I have to remember everything I said and try again, but otherwise I think it works better than Wispr Flow

Fantastic for self-hosting ai

Great if you self-host your own ai models for cleanup. total privacy

Perfect dictation even for my speech impediment.

I found this app with help from Claude AI, and downloading the on-device Whisper Small model has been a game changer for me. I have a speech impediment and rely on voice dictation daily, and this app understands me far more clearly than Apple's built-in dictation ever has. Being able to use it completely free, unlimited, and offline means a lot to me.

A couple of bugs I've run into: I get an orange error popup every time I finish dictating that says something went wrong, but the text comes through correctly anyway. Also, the keyboard doesn't seem to work until I open the Diction app itself first each session — it needs to "wake up" before it'll work in other apps.

Even with those bugs, this app has genuinely helped people understand me better. Thank you for building something this good and giving it away for free.

非会员标点保留

自建服务器在非会员的情况下,会自动把我模型给出的标点符号吃掉。你们的标点辅助功能,这个本身有点鸡肋吧,末尾自动加上句号,这个功能并不实用。不过,不至于在 试用期结束后,把自建模型产生的标点全部吃掉吧,吃掉以后几乎毫无实用性,只能开订阅或者会员?

期待有所改进吧。

Response from developer

嗨!真的很谢谢你花时间反馈,也谢谢你的耐心——你的建议对我们很有帮助 🙏 先给你吃颗定心丸:自建服务器一直是、以后也会一直是完全免费的,跟试用期没有任何关系,绝对不是付费墙。给你造成困扰,真的很抱歉。 简单说明一下自建模式:你的转写完全来自你自己的服务器,Diction 只是把服务器返回的文字原样插入,不做任何云端润色或标点处理。所以标点效果主要取决于你用的模型本身。 而自建最棒的一点,就是一切都由你掌控:你可以换一个标点更规范的模型,或者在你自己的服务器上接上你喜欢的 LLM + 提示词做后处理——Diction 会把结果原样呈现,风格完全按你的喜好来。 如果你愿意,我很乐意亲自帮你把它调到最顺手的状态:把你用的自建服务和 App 版本发到 support@diction.one,我会一步步陪你搞定。真的谢谢你选择自建、也谢谢你支持 Diction 🙏

Nice for da price!

. So um I have a problem typing at times my hands cramp I was uh born with a stroke, I know boo-hoo. The point is, is that um diction is affordable, rarely fails and is just reliable. And for someone like me I need that. So thank you, Diction.
