Pricing questions

Is it a subscription?
No, it’s a one-time purchase. Pay once and your exports are yours for good. Until November 30, the founding price is 50% off with code FOUNDING50.
Does it export to PDF?
The core export is built for AI, so it’s clean, token-efficient text rather than a PDF. Need other formats? The Pro plan adds PDF, Word, Excel, and CSV, and Export All Conversations. If you only want a printout for legal or archival use, a plain PDF exporter may be all you need.
Do I need to pay again for 1.1?
No. If you bought Lembic, every update is free, and that includes 1.1. The new prices are only for new buyers.
Lembic asks me to check my license after the update. Why?
Lembic 1.1 checks each license one time after the update. This check does not use one of your Mac slots. Connect to the internet and click Check Again. If a firewall app blocks the check, allow activate.textstoai.com.
All my Macs are used. What do I do?
One license works on 3 Macs. To free a slot, open Lembic on a Mac you no longer use and choose Lembic › License › Deactivate this Mac. If you do not have that Mac, remove it on the devices page at activate.textstoai.com.
Can I get a refund?
Yes. Lembic has a 30-day money-back guarantee, for any reason. Email [email protected] within 30 days of your purchase.
Which macOS versions are supported?
macOS 14 (Sonoma) or later, on Apple silicon or Intel.
