AudioPen Alternative: Slax Note — Voice Notes That Become Posts You Can Ship
AudioPen vs Slax Note — both turn voice into clean text. Slax Note's custom Prompts are shareable, and Prompt-driven rewriting is included from the entry tier (AudioPen's Restyle is Prime-only).
You ramble for 90 seconds into AudioPen. It hands you back a clean paragraph. Useful — but you wanted a tweet, a LinkedIn post, and a note for later. So you copy the result into ChatGPT and re-prompt for each.
That’s the gap Slax Note is built around. Save your own Prompts — and share them with other Slax Note users — so the same recording becomes a tweet, a post, a note, or a draft without leaving the app.
AudioPen is excellent at “one polished paragraph from one memo.” If that’s the whole job, you don’t need to switch. Read on if it isn’t.
At a glance
Go for Slax Note if…
- You write across multiple channels and want each output to sound right, in one place
- You want Prompts you can share with other people, not just save for yourself
- You’d rather pay $4.99/month and cancel anytime than buy a fixed-window plan
Stick with AudioPen if…
- You only need one clean paragraph per memo
- You depend on the Mac app for system-wide voice typing
- You depend on Zapier and webhooks to push notes elsewhere
- You’d rather pay once a year and own the window outright
One sentence: AudioPen turns rambling into a clean paragraph. Slax Note turns the same recording into the channels you actually publish to.

What AudioPen Does Well
Let’s be honest. For a single-operator product (built and run by Louis Pereira since 2023), AudioPen ships fast and covers a lot.
What stands out:
- Rewriting Intensity — three levels with real, distinct behavior. Low = cleaned-up transcript only. Medium = rewritten in your chosen style but keeping your vocabulary and tone. High = full rewrite, your choice of style and length
- Mac app with system-wide voice typing — M1+ Macs get a real productivity unlock. Speak in any text field on the OS, get clean text. Slax Note doesn’t have this
- Chrome extension — one more place capture lives
- Audio file upload — drop in a 100MB recording, get the same rewrite pipeline. Prime allows 100 files / 4 weeks
- SuperSummaries — merge multiple notes into one. Useful for weekly reviews
- Restyle existing notes + process pasted text — the AI pipeline isn’t tied to “fresh recording”
- Zapier + webhooks — pipe finished notes into Notion, Obsidian, email, anywhere
- One-time pricing — pay once, own the window. No recurring charge until you renew
If your daily workflow is “memo → polished paragraph → push elsewhere,” AudioPen has earned its place.
Where Slax Note Goes Different
The short version: AudioPen rewrites your words; Slax Note shapes them into the channels you actually publish to — and the Prompts that do the shaping are shareable.
Prompts that travel between users
AudioPen’s Writing Styles cover formal email, legal, bullet points, and similar — plus user-created custom styles. Custom styles stay inside your own account.
Slax Note’s Prompts are shareable. You write your own — full instructions for the output you want — and you can share them with other Slax Note users:
- “Turn this into a 280-character tweet, sharp opener.”
- “Make this a LinkedIn post, 200 words, professional tone.”
- “Rewrite as a blog draft with subheads.”
- “Pull out the decisions into a separate bullet list.”
Same audio, four outputs, side by side. You keep what you want.
Restyle is included from the entry tier
AudioPen’s “Restyle existing notes” — applying a different rewrite to a recording you already made — is a Prime-only feature. Slax Note’s Prompt-driven rewriting works from the entry tier on. If you live in the “I want to try this same recording in another shape” loop, that matters.
Pricing posture
AudioPen is one-time and time-boxed: $33 / 3 months, $99 / 1 year, $159 / 2 years. Slax Note is monthly subscription with cancel-anytime: $4.99/mo or $49.99/yr.
Roughly the same yearly cost. Different commitment shape.
Pricing — Different Shapes
AudioPen sells one-time, time-boxed plans: $33 / 3 months, $99 / 1 year, $159 / 2 years. No monthly. Renew at the end. Slax Note Pro: $4.99/month or $49.99/year. Cancel anytime.
If you want commitment-shaped pricing and a known one-shot cost, AudioPen’s model is friendlier. If you want to try monthly and quit if it doesn’t fit, Slax Note’s model is friendlier.
“AudioPen sells you a refined pen. Slax Note sells you the channels you ship to.”
How we think about this
Two beliefs shape Slax Note.
Personal first, not meetings. Meeting tools pull a product toward speaker separation, calendar integration, attendee detection, enterprise pricing — each one drags it away from the person walking down the street with an idea. AudioPen and Slax Note both made the personal-first bet, just from different teams.
Built to be here in five years, growing with you. The point of voice notes isn’t today’s recording. It’s what your library looks like after three years — the walk-the-dog idea from last March that helps you write something today, the half-thought from a year ago that turns out to be the seed of next month’s project. So we keep the product small, the team lean, the runway long. We use this ourselves every day, which is the only honest reason to believe it’ll still be here when you need it.
What Slax Note Doesn’t Have Yet
We’d rather you switch with both eyes open. What AudioPen has that we don’t, today:
- Mac app with system-wide voice typing — we don’t have this. If you write across many apps on macOS and want to dictate into all of them, AudioPen’s Mac app is a real differentiator
- Chrome extension — not built
- Zapier + webhooks — not built. Sharing happens inside the app today
- SuperSummaries — combining multiple notes into one isn’t in the product yet
- Restyle existing notes / process pasted text — Slax Note’s pipeline is built around fresh voice input today
- Long recordings — Slax Note caps each recording at 30 minutes. AudioPen Prime caps at 15 minutes per recording but allows audio file upload up to 100MB, so real long-form is more accessible there
If any of those are core to your daily workflow, stay with AudioPen — or run both.
Other Alternatives We Considered
- Voicenotes — Now leads with Meetings; Memos is a sub-product. Strong if your real job is meeting notes too. See comparison →
- Mem AI — AI-native notes with Voice Mode and chat-across-archive. Heavier on retrieval than rewriting. See comparison →
- Braintoss — Pure capture-to-inbox at $2.99 / $3.49 one-time. Best if speed-to-inbox is the only thing you want. See comparison →
FAQ
Is Slax Note really free to try? Yes. Free plan: 5 saved notes, 10 AI Polish runs total, recordings up to 5 minutes. Pro ($4.99/mo or $49.99/yr) lifts those limits to unlimited notes, 300 polishes per day, and 30-minute recordings.
Do I have to give up AudioPen? No. Run both for a few weeks. AudioPen for “one clean paragraph” and Mac voice typing; Slax Note for “this recording needs to become several outputs.” See which one you reach for more.
Does Slax Note have a Mac app? No. iOS, Android, and the web (n.slax.com) today. If system-wide voice typing on macOS is core, AudioPen’s Mac app is what you want.
What languages does Slax Note support? The app UI is in English, 中文, and Português. Voice transcription supports English, Chinese, German, and Japanese (per the marketing page).
