CallGPT 6X
CallGPT 6X's real differentiator isn't the model aggregation itself, since several tools do that, but the client-side redaction step, which is a genuinely useful feature for regulated workplaces worried about staff pasting sensitive data into a chat box. The cheapest $9.99 tier only unlocks budget models — the frontier models most people actually want require the $29.99 Professional tier or above.
Pros
- Client-side redaction of sensitive data (national insurance numbers, card details) before it leaves the browser
- Access to 20+ models from multiple providers in one interface
- Backed by Google, Microsoft and NVIDIA startup programs, with a named founding team and registered UK office
Cons
- Cheapest tier ($9.99) excludes the major-brand models most users want
- No API — access is through the web workspace only
- No launch date disclosed, making it hard to gauge how established the product is
