🤔 How to Choose
Let's be clear about this first: if all you want is to take notes properly, the free version is enough.
The One-Line Test
- Free: what you want is "to get it written down" — voice, translation, clipping, notes, sync, export, all unlimited.
- Pro: what you want is "to get it organized" — AI Summary and Mind Map turn what you've noted into something you can use.
- Max: what you want is "more high-accuracy voice transcription quota, and more usage of the advanced AI capabilities."
Suggestions by Type of User
| Who you are | Suggestion | Why |
|---|---|---|
| Student, mainly recording classes | Free → Pro | Class recording transcription is fine on free; move to Pro when you need review mind maps and summaries |
| Working professional, lots of meetings and foreign languages | Pro | AI Summary and Realtime Translation save time directly |
| Want to understand yourself through your notes | Pro | Deep Insight needs a certain volume of notes to work well |
| Just want somewhere to jot things down | Free | That's really enough |
Write for a While Before You Decide
This is our honest advice.
Capabilities like Deep Insight are built on top of "how much you've recorded."
When there are too few notes, even the strongest AI has nothing to read. Use the free version for a month first; once you have a few dozen real notes, decide whether to pay for AI capabilities — by then, every cent you spend will be worth it.
If You're Still on the Fence
Then just start with the free version.
We won't push you with pop-ups, we won't push you by crippling features, and we won't throw up a paywall halfway through a note.
That wouldn't fit why we made this product in the first place.
Every feature is quiet. When you need it, it's there; when you don't, it stays out of the way.
Special Thanks: inFin's Old Friends
inFin iOS has been live for more than two years — free, ad-free, no growth hacking, unlimited use, growing naturally.
2.0 brings stronger AI capabilities, and for the first time introduces memberships; but all note features and iCloud sync are still unlimited.
To make sure the earliest friends who supported us aren't left behind, on the launch of 2.0 we prepared a special gesture — Legacy User Lifetime Pro.
All slots for this offer have now been fully claimed and are no longer open. The content below is a recap of the offer and a description of the benefits, for our old friends who already participated.
🎁 Legacy User Lifetime Pro (Special Notice)
Historical mainland-China offer, now closed. The CNY amounts below preserve the original offer and refund terms; they are not the prices of current international subscriptions. See current USD plans.
What This Gesture Is
Old users can unlock inFin Pro lifetime benefits for ¥199 — the price of a one-year Pro subscription. See Legacy User Lifetime Pro.
Pay for one year, get it for life: all Pro features already live, and every one still to come.
This isn't a promotion, it's a thank-you. We didn't want the people who've supported us the longest to end up paying more.

On the Definition of "Lifetime"
"Lifetime" in this page means the period from the date of activation until the day inFin's related services cease operation; during this period, you'll continue to enjoy all Pro benefits.
This benefit is tied to the account used at activation. It doesn't expire when you change devices, but it cannot be transferred to another account.
If, due to legal regulations, policy adjustments, or force majeure, the scope of benefits needs to change, we'll announce in advance through official channels and won't reduce the core benefits already granted to activated users.
On the ¥199
¥199 matches the original price of a Pro annual subscription. It is the special pricing for this particular offer, not a separate new price tier.
⚠️ Refund, Transfer, and Change Notice
The Legacy User Lifetime Pro offer is a limited, special event, and its benefits differ from regular subscriptions, so the following special rules apply. Please read them carefully before activating.
1. No refunds, transfers, or changes
Once activated, you are deemed to have fully understood and agreed to the rules of this event. No refunds, and no transfers, gifting, account changes, splitting, or changes to a different benefit type are supported.
2. The only exception: inability to continue service for reasons attributable to the official side
If, for reasons on inFin's official side (such as the product ceasing operation), you are unable to continue using this service within one year of activation, we will refund based on a one-year period at the ¥199 baseline, prorated by the remaining unused days:
Refund amount = ¥199 × (remaining days ÷ 365)
3. After the one-year period
¥199 matches the original price of a Pro annual subscription. After one full year of activation, you are deemed to have fully enjoyed one year of Pro service, and no further refunds, transfers, or changes will be accepted.
4. Situations not covered by the refund
Situations caused by personal reasons (such as changing devices, no longer using the service, accidental purchase, or account suspension due to violation) are not covered by the exception above.
This policy does not affect any statutory rights you enjoy under applicable law.
Will It Open Again Later?
In principle, no. If a small number of additional slots open under special circumstances, we will announce it in advance through official channels (official website, WeChat, in-app notification).
FAQ
Q: Are there any slots left?
No. A total of 1,100 slots across the two batches have all been claimed, and the event is over.
Q: I'm an Android user — is Lifetime Pro the same as on iOS?
Exactly the same. Account benefits apply across iOS, Android, and any future platforms, and data will be progressively shared.
Q: Does Lifetime Pro include future Max features?
It includes all Pro features. Max is a higher tier and is not within the scope of Lifetime Pro.
Q: I already bought annual Pro — can I convert it to Lifetime?
This event has ended, and conversions are no longer accepted. Your existing annual Pro can be renewed at the then-current subscription policy when it expires.
Q: Can I transfer my Lifetime Pro to a friend?
No. Benefits are bound to the activating account and cannot be transferred, gifted, or moved to another account.
