It joins identity, intent, and call history to your agent's memory at Cloudflare edge latency, with sub-300ms voice recall as a design target."},{"q":"Who is Mnemix for?","a":"Developers building AI voice agents on platforms like Vapi, Retell AI, Bland AI, LiveKit, or directly on Twilio. Also chat developers who want phone-native identity."},{"q":"How is Mnemix different from Mem0?","a":"Mem0 is a general-purpose bolt-on memory layer with strong mindshare, 21+ agent-framework integrations (LangChain, CrewAI, AutoGen, and others), and 19 vector backends. It extracts and retrieves chat facts across sessions — but does not resolve phone callers or fan out Twilio Lookup + Trestle + Baylio enrichment before a voice turn. Mnemix is voice-first with caller-ID enrichment built in, runs on Cloudflare Workers at the edge, and ships first-class integrations with Vapi, Retell, and Bland. Choose Mnemix if you're building voice. Choose Mem0 if you need a general-purpose memory layer with deep vector-store and framework choice."},{"q":"How is Mnemix different from Zep?","a":"Zep + Graphiti is the research-cited bi-temporal knowledge graph for chat agents. Mnemix is voice-native with built-in caller-ID enrichment. Zep's voice support is a community demo; Mnemix ships first-class integrations with Vapi, Retell, Bland, and Twilio. Choose Mnemix if you're building voice."},{"q":"How is Mnemix different from Supermemory?","a":"Supermemory and Mnemix share the same Cloudflare Workers stack. The difference is voice + enrichment: Mnemix bundles Twilio Lookup, Trestle, and Baylio call-intent into the memory primitives. Supermemory is general-purpose memory. Choose Mnemix if you're building voice."},{"q":"How is Mnemix different from Letta?","a":"Letta deprecated its voice endpoint in March 2026 (HTTP 410 in letta/server/rest_api/routers/v1/voice.py). Mnemix is voice-first. Choose Mnemix if you're building voice."},{"q":"How is Mnemix different from LangMem?","a":"LangMem is bound to LangGraph and is aimed at graph-backed agent workflows, not cold-caller voice recall. Mnemix is designed for sub-300ms voice recall with caller enrichment in the hot path. Choose Mnemix if you're building voice."},{"q":"How much does Mnemix cost?","a":"Hobby is $0/month — free tier with 50 sessions, 1,000 memory operations, and 100 Twilio Lookups. Starter, Pro, and Elite tiers are in private beta — contact hello@mnemix.ai for pricing while we wire billing."},{"q":"Is there a free tier?","a":"Yes. Hobby is $0/month with 50 sessions, 1,000 memory operations, and 100 Twilio Lookups. Attribution required (Powered by Mnemix). Sign up at https://mnemix.ai."},{"q":"What latency does Mnemix offer?","a":"Mnemix is designed for sub-300ms voice recall at the Cloudflare edge. We publish measured numbers only once they are real — we would rather under-promise and ship honest results."},{"q":"Where does Mnemix run?","a":"Cloudflare Workers (edge), with Durable Objects for session state, R2 for blob storage, KV for hot cache, and Supabase Postgres + pgvector for the durable memory store."},{"q":"Does Mnemix support the OpenAI Assistants API?","a":"Yes — Mnemix is a migration target for voice teams. The OpenAI Assistants API is shutting down 2026-08-26, and Mnemix carries caller identity, enrichment, and memory across the move."},{"q":"Does Mnemix integrate with Vapi?","a":"Yes. The Vapi integration drops the Mnemix middleware into your Vapi function-call handler so callers arrive already enriched."},{"q":"Does Mnemix integrate with Retell AI?","a":"Yes. The Retell integration adds caller-ID enrichment and conversation memory to your Retell agent."},{"q":"Does Mnemix integrate with Bland AI?","a":"Yes. See https://mnemix.ai/integrations/bland."},{"q":"What benchmark scores does Mnemix have?","a":"Mnemix does not publish benchmark numbers yet. Voice-grade memory benchmarks will ship only once they are independently measured — we would rather show real results than projected ones."},{"q":"Is Mnemix open source?","a":"The enrichment SDK is MIT-licensed on GitHub. The memory layer is closed-source SaaS with self-host coming for Elite tier."},{"q":"Is Mnemix HIPAA-compliant?","a":"Not as a present-tense guarantee. Mnemix is building toward SOC 2 and GDPR alignment, and HIPAA support with a BAA is on the roadmap — none are certified today. Email hello@mnemix.ai to talk through compliance timelines for your use case."},{"q":"Where is Mnemix data stored?","a":"Cloudflare's global edge holds hot session state; durable storage runs on Supabase (US, Pro). Email hello@mnemix.ai about EU data-residency requirements."},{"q":"How do I get started with Mnemix?","a":"Sign up at https://mnemix.ai for a free Hobby key and install the SDK (npm install @mnemix-ai/client). For cold voice callers, call POST /v1/recall_and_enrich before the first turn; use POST /v1/context for known callers, chat, and workflow context."}],"targetQueries":["best memory api for ai voice agents","how do i add memory to a vapi voice agent","how do i add memory to a retell ai agent","twilio caller id enrichment with ai","letta voice deprecated alternative","mem0 alternatives","zep alternatives","openai assistants api replacement","cloudflare workers memory database","phone number to person lookup api","real-time memory for ai agents at the edge","voice agent memory api"]}
