undetectable.wtf
What is undetectable.wtf?
undetectable.wtf is a browser-based AI humanizer that takes drafts from ChatGPT, Claude, and similar writers and reworks them so common detectors flag less often. You paste up to 15,000 characters into the homepage editor, pick Rewrite or Cryptography mode, and run output against tools like GPTZero, Turnitin, and ZeroGPT. The site lists a 98% bypass success rate and a 4.9/5 rating from 2,300+ users.
Most humanizers only paraphrase. undetectable.wtf also ships Cryptography mode, which swaps in Unicode homoglyphs and zero-width characters so the text looks unchanged to readers while breaking detector pattern matching. That is a different trade-off than rewrite-only services, and both modes here count against monthly essay quotas rather than offering unlimited character processing.
Students, freelance writers, and research assistants use it when AI-assisted drafts need to clear school or client checks. Signup includes a 3-day trial with 2 essays and no credit card. Paid Standard and Pro tiers raise the monthly essay cap, and Pro unlocks input limits up to 2x Standard capacity.
Siwalu
What is Siwalu?
Siwalu builds AI image recognition apps that identify dog, cat, and horse breeds from a phone photo in seconds. Dog Scanner, Cat Scanner, and Horse Scanner tell you pure or mixed breed guesses plus trait notes, which saves pet owners and rescues from waiting on DNA lab results when they just need a quick answer.
Generic visual search apps label objects broadly. Siwalu focuses on animal breeds with a social feed, gamification collectibles, and a Snapchat Camera partnership that runs Dog Scanner through Scan. The homepage reports 28,089,019 total app downloads and about 1,920,000 animals identified each month, and it also offers a business API for partners who want breed detection inside their own products.
Pet owners, animal rescues, and nature curious users scan shelter dogs, barn cats, or riding horses to learn breed makeup and characteristics. Reviews on the site highlight mixed-breed percentage results and rescue teams using scans before paying for DNA tests, while media coverage from TechCrunch and The Verge centers on the Snapchat integration.
