SayScribe AI - 音频转文字的在线工具 花了几周搞了一个基于 OpenAI Whisper 的 AI 转录工具 **[SayScribe]( https://sayscribe.org)**,目前 5 个工具全部免费,每天 3 次无需注册。上线前请 SEO 专家做了一轮诊断,踩了不少坑,分享出来给同样在做工具站的 V 友参考。 --- ## 做了什么 核心工具是 **[Audio to Text Converter]( https://sayscribe.org)**(主页),上传音频/视频文件,AI 自动转成带 speaker labels 和时间戳的文字稿。选这个词的原因是:Google 第一页有个 DR 只有 10 的小站排第三,KD 才 20.2 ,链接预算只要 15-35 个引用域就能进前十——典型的弱盘面蓝海。 然后在主页基础上拆了 4 个子工具,每个打一个独立搜索词: - **[MP3 to Text]( https://sayscribe.org/mp3-to-text)** — 只转 MP3 。KD 41.7 比主页难一些,但

Combine notes on an infinite canvas and export sequences as PDF pages.
@JonnyD · X
I'm happy to announce "Mash" A local first browser based app for compiling notes and ideas on an infinite canvas. Make as many notes as you want, drag and drop to "Mash" them by combining. Create "sequences" that allow you to export a pdf with each sticky as it's own page. Drop in PDF or DocX or images to easily browse the file and select your favorite clippings to a new canvas, and manipulate them or export them how you want to. Drop a GIF to get all the individual frames. Mash features a roster of cute food themed mascots because this is your infinite textual stove top. Pull in some ingredients, mash them together, stitch them together, arrange them into a flow chart, whatever you find useful, and then get out quickly. Mash is for the little moments that speed up work, and the spontaneous thoughts that inspire new directions. There is no fancy AI feature, no data collection, no login, just a utility for you. Free open source licence. Run it offline if you want

AI phone copilot that records, transcribes, and extracts insights from business calls in the browser.
u/carlosmarcialt · Reddit
I spent months building my SaaS and completely forgot the marketing part I just realized Voxandra has had exactly zero marketing. Not bad marketing. Literally none. So this Reddit post is now the entire marketing department. Voxandra is an AI phone copilot for people and teams who still get real work done over phone calls. Supplier calls, payment follow ups, claims, banks, government offices, universities, and all the other places that somehow still behave like email was never invented.

Take notes on YouTube videos to track ideas and understand viewer engagement for content creators.
u/Wolf-soul-site · Reddit
I cut the one feature every user asks for, because shipping it would've meant lying to them. I'm building Margin( https://margin.bhairav.ai ), a tool that helps YouTube creators decide what to make next. The #1 request is a number: "this idea will get ~40K views." Every competitor shows one. Users ask for it constantly. I won't build it. Nobody can predict a video's views from an idea. Thumbnail, timing, the algorithm, luck, none of it exists yet when you're validating. Any number I sho
