Zap2Doc's answer
Anyone who needs to document an important WhatsApp conversation: people working out agreements, negotiations, professional records, or organising long chats they want to keep. Strongest demand in Brazil, India, and the MENA region, where formatted chat records carry weight in real-world disputes.
ClientForms.app's answer:
Psychologists who assess ADHD and autism. Typically private practice, solo or small group (1-5 clinicians), currently using paper forms and spending hours on admin per assessment. They want something that works and is secure.
Zap2Doc's answer
Most tools either export WhatsApp media OR transcribe voice notes — Zap2Doc does both, in a single PDF that preserves the full chronology of the conversation. Upload the .zip export, get back a professionally formatted document with messages, images, and audio transcriptions in order. No app to install, no account required.
ClientForms.app's answer:
Neurodivergent-first design. Most digital forms just replicate paper online. ClientForms is built specifically for ADHD and autism patients - progress bars with time remaining (helps with time blindness), softer colours instead of harsh white, sticky headers so you always know where you are. The forms are designed to reduce anxiety and improve completion rates.
Zap2Doc's answer
One-off payment (no subscription), 8 languages out of the box (en/pt/es/fr/de/it/hi/ar), free preview before you pay, files up to 2 GB, audio transcription powered by Whisper. Most alternatives lock features behind monthly plans or only handle one part of the workflow.
ClientForms.app's answer:
Most clinical software treats patients as an afterthought. ClientForms is designed specifically for neurodivergent users who are filling out the forms, progress indicators, time estimates, calmer colours, predictable layouts. One link, no signup required, works on any device. Patients just open and complete.
Zap2Doc's answer
The founder got scammed by a repair shop and his lawyer asked for an organised record of the WhatsApp thread to build the case. Existing tools were either expensive subscriptions, mobile-only, or stripped out the audio messages entirely. Zap2Doc was built to be the tool he needed that day.
Zap2Doc's answer
Zap2Doc is a self-serve product used by individuals — no enterprise contracts. Top markets so far: Brazil, the US, Germany, India, and the MENA region.
