Found a Free AI Audio Enhancer Worth Trying – Sharing It Here!

I've been looking for an easier way to clean up audio recordings lately. Sometimes I record something for a video or just want to save a voice recording, but the background noise can be really distracting. Things like fan noise, echoes, and random sounds in the background can make an otherwise decent recording hard to listen to.

I know there are professional audio editing programs out there, but honestly, I don't always want to spend time figuring out complicated settings just to fix a recording.

Recently, I came across a tool called AudioEnhancer, and thought it might be worth sharing with anyone who has similar needs.

What I Like About It

The first thing I noticed is that it's browser-based, so there's no software to download or install. You can just visit the website and upload your audio.

It also doesn't require an account to get started, which is always nice when you just want to try something quickly.

What makes it more interesting is that it offers quite a few different audio cleanup options:

Remove background noise like fan sounds, hum, and hiss.
Remove echo and reverb from recordings.
Reduce wind noise in outdoor recordings.
Remove distracting mouth sounds and breathing.
Clean up long silences and speech hesitations.
Normalize volume to make audio levels more consistent.
Enhance speech for a cleaner, more polished sound.

I like that these tools are available in one place instead of having to look for a separate website for every little audio problem.

A Few More Things Worth Mentioning

One thing that caught my attention is that it supports both audio and video files. That's convenient if you have a video with poor audio and don't want to extract the sound separately before cleaning it up.

There are also several ways to import content, including local file uploads, recording, links, and screen recording.

Another useful detail is that there's no audio duration limit, so it can be considered for longer recordings like podcasts, interviews, and online meetings.

I also noticed that it offers two AI processing models, V1 and Alpha V2, giving users different processing options depending on their needs.

Who Could Find This Useful?

I think this could be handy for quite a few people:

Podcasters who want to reduce background noise in their recordings.
Video creators who need cleaner voiceovers or clearer audio in their videos.
Students who record lectures and want to make them easier to listen to.
Remote workers who deal with meeting recordings.
Anyone who wants to improve a voice recording without learning professional editing software.

Of course, the results will depend on the original recording, but having different cleanup tools available makes it worth checking out.

Final Thoughts

I always appreciate finding online tools that solve a specific problem without making the whole process complicated.

AudioEnhancer seems like a convenient option if you occasionally need to clean up recordings but don't want to install professional software or deal with a steep learning curve.

It's free to try and doesn't require registration, so there's not much of a barrier to checking it out.

Hope this helps someone who's been looking for a simple audio cleanup tool!

DocMaker AI: Turn an outline into an editable document

Shutter Shanti — Fri, 30 Oct 2026 11:04:37 +0000

DocMaker AI is a browser-based AI document generator and online editor for turning ideas, notes, and reference material into editable drafts. It supports documents such as project proposals, business plans, reports, standard operating procedures, and study guides.

Give the draft a clear brief

A useful starting prompt names the document, its audience, the information it must include, and any details that should remain as placeholders. For example:

Draft a client project proposal for a website redesign. The audience is the client’s operations team. Include the project goal, scope, deliverables, timeline, assumptions, and next steps. Use placeholders for the client name, dates, and prices. Do not invent project facts.

You can also choose a template or upload source material to give the generator context. The resulting draft can include headings, paragraphs, lists, and tables.

Revise the content and check the layout

After generation, you can edit wording and text formatting directly or ask AI to revise a section. Requests such as “shorten the introduction,” “turn these notes into a checklist,” or “add a section for project assumptions” give the revision a specific purpose.

The workspace includes a page preview, so you can check spacing, page breaks, and the structure of a longer document while editing it. Formatting controls include text size, color, alignment, bold, and italic. Earlier versions remain available as you continue working.

Review before downloading

Treat the generated document as a draft. Check names, dates, figures, citations, and any claims against your own sources. Replace placeholders, remove unsupported details, and confirm that the document fits the intended audience before using the Download menu.

DocMaker AI is free to start and can be used without creating an account.

The WhatsApp outreach prompt stack I actually use (with a real workflow)

Shutter Shanti — Tue, 23 Jun 2026 08:26:50 +0000

Sharing a workflow I've been running for a while that combines Claude/ChatGPT with bulk WhatsApp sending — might be useful for anyone doing personalized outreach.
The problem with WhatsApp templates
Most people writing WhatsApp message templates do it manually, which means every message sounds either too generic or too stiff. The sweet spot is a message that reads like a human wrote it for that specific person — but you need to generate 200 versions of it without spending 3 hours on copy.
The prompt stack
Step 1 — generate the base template. I use this with Claude:
Write a WhatsApp message template for [use case: appointment reminder / sales outreach / order update].
The message should:

Be under 160 characters
Include {{name}} and {{detail}} as placeholders
Sound like it was typed by a person, not a CRM
No emojis unless the context calls for it
End with a soft CTA, not a hard sell Step 2 — stress test it. I then ask: Read this WhatsApp template back to me as if you are the recipient seeing it for the first time. Does it feel personal or does it feel like a mass message? What would you change? This almost always catches something — usually the opening line. Step 3 — variation generation. For different segments (cold leads vs existing customers vs lapsed users) I run: Give me 3 variations of this template for:
Someone who's never heard of us
A returning customer
Someone who signed up but never used the product Where the CSV comes in Once I have the template locked, I drop it into Premium Sender with a CSV — name, phone, and whatever {{detail}} field the template uses (appointment time, product name, etc). Each person gets their own version, messages go out through WhatsApp Web, and I get a delivery report after. The prompt work upfront is what makes the actual send feel human at scale. Without it you're just blasting the same stiff sentence to everyone. Anyone else running a similar stack? Curious what prompts people use to QA message tone before sending to a list.
