AI 2nd Line + Receptionist vs MultipleChat AI

Your second phone number with a built-in AI receptionist. VaiA gives you a real local number for calls and texts — answered by an assistant that works for you. YOUR AI ANSWERS THE PHONE • Every call is screened live — watch the transcript scroll word by word • Whisper instructions mid-call ("ask what it's regarding") and your assistant says it naturally • Take over the call yourself with one tap, or let the AI take a message • Voicemails are recorded and transcribed automatically IT MAKES CALLS FOR YOU Tell your assistant "call the restaurant and book a table for four" — it dials, has the conversation, and reports back with the outcome. A REAL SECOND LINE • Send and receive texts from your VaiA number • Get alerts when texts arrive — with your assistant's quick read on what they want • Sync contacts so callers show up by name • Call your own number and your assistant briefs you on what you missed (passcode protected) MAKE IT YOURS • Name your assistant, set its personality and greeting, choose its voice • Add knowledge so it answers questions about you or your business • Pro: up to 3 lines, each with its own separate assistant Plans include monthly AI talk-time minutes (Base 100, Pro 300), with top-ups available. Subscriptions bill through your Apple ID and renew until cancelled. ——— Terms of Use (EULA): https://ai-second-line-api-production.up.railway.app/terms Privacy Policy: https://ai-second-line-api-production.up.railway.app/privacy

Stop betting on one AI. MultipleChat runs ChatGPT, Claude, Gemini and Grok in a single workspace — so you can compare what they say, or put them to work on the same question together. ONE QUESTION, EVERY MODEL Send one prompt and see how each model answers, side by side. Where one is vague, another adds depth. Where one gets it wrong, another catches it. BUILD YOUR AI TEAM Assign roles and let the models work in order — one drafts, another edits, a third reviews. Choose how they collaborate: Smart, Conversation, Ensemble, Co-operative, Debate, Simulation, Expert or Research. ANSWERS YOU CAN CHECK A built-in verification layer reviews the output and flags claims that aren't well supported, so you know what to trust before you use it. STUDIOS FOR REAL WORK Turn a conversation into a finished file without leaving the app. - Document Studio — reports, proposals, whitepapers, meeting minutes, cover letters - Excel Studio — spreadsheets and models, with free Python tools built in - Presentation Studio — slide decks with the tone, style and length you choose - Image Studio — generate and edit images across several image models YOUR FILES, YOUR CONTEXT Upload PDFs, spreadsheets and documents, or connect Google Drive and GitHub. Organise everything into Projects so each conversation starts with the background it needs. BUILT FOR TEAMS Shared projects, a common knowledge base, shared prompts and files, and centralised admin for groups of any size.
