What's the difference between Free and Pro? ▾
Free uses DeepSeek V3 and is limited to 3,000 characters per file (good for testing). Pro uses GPT-4o-mini (better quality), allows up to 50,000 characters per file, and has no monthly file limit.
Is the Lifetime deal really forever? ▾
Yes. Pay once, get your kaerisp_ key, use it forever with no recurring fees. All future Pro features included. This is a launch promotion — price will increase once we hit 100 buyers.
