marv.Inbox vs TimelinesAI: Personal-Number Sync or an Official-API Team Inbox
Picture a sales floor where every rep already chats with leads from their own WhatsApp, and the real pain is that none of it lands in the CRM. TimelinesAI is built for exactly that: it links individual personal numbers by QR, with no limit on how many, and syncs deeply two-way into HubSpot, Pipedrive, Salesforce, Close, monday, and Zoho. That deep CRM sync is its genuine strength. marv.Inbox takes a different path: one official WhatsApp Business API number that the whole team shares, with queues, a clear owner per conversation, and SLA. If your model is many reps each keeping their own number, TimelinesAI fits it directly. If you want a shared business number run as a team operation on the official API, that is marv.Inbox.

Why teams search for this
Personal-number sync and a shared API inbox are different setups
Both tools put WhatsApp to work, but on different foundations. TimelinesAI is built on personal numbers linked by QR; marv.Inbox is built on the official WhatsApp Business API. That foundation shapes everything from ownership to compliance.
- ▲TimelinesAI links individual personal numbers by QR with no cap on count, and its deep two-way CRM sync covers HubSpot, Pipedrive, Salesforce, Close, monday, and Zoho.
- ▲marv.Inbox runs one official API number as a shared inbox with queues, a per-conversation owner, and SLA, rather than syncing many separate numbers.
- ▲The official API brings approved templates and opt-in handling; a personal-number setup does not carry the same template and opt-in model.

Workflow
How to choose based on your setup
Decide whether reps should each keep a personal number or share one business number. TimelinesAI fits the first; marv.Inbox fits the second.
Weigh how much CRM depth you need. If two-way sync into your CRM is the top priority, that is TimelinesAI's strength.
Consider compliance and longevity. The official API gives approved templates and opt-in; if you plan to scale outbound, that foundation matters.

Questions teams ask before changing the workflow
What is the difference between a personal number and the official API?+
TimelinesAI links each rep's personal WhatsApp by QR, so conversations stay on individual numbers. marv.Inbox runs the official WhatsApp Business API on one shared business number, which brings approved templates, opt-in handling, and a shared team inbox. The personal-number route is lighter to start; the official API is the compliant foundation for team and outbound use.
How deep is the CRM sync compared to marv.Inbox?+
CRM sync is TimelinesAI's strength: deep two-way sync into HubSpot, Pipedrive, Salesforce, Close, monday, and Zoho. marv.Inbox connects to your stack through integrations but is built around the shared team inbox rather than CRM logging. If two-way CRM sync is the priority, TimelinesAI leads there.
When is moving to the official API worth it?+
When several people need to share one business number, when you want approved templates and opt-in for outbound, or when you need queues, owners, and SLA on a single number. At that point a personal-number setup starts to strain, and the official API that marv.Inbox runs on is the more durable base. Because marv.Inbox connects in Coexistence mode, moving up keeps your existing business number and its WhatsApp Business app, with recent history synced in, rather than starting from a blank API line.
How hard is it to migrate from TimelinesAI to marv.Inbox?+
The main change is consolidating personal numbers into one official Business API number, which you connect through marv.Inbox in Coexistence mode so it keeps running in the WhatsApp Business app with its recent history, then set up queues and owners. Keep your CRM integrations in mind, since TimelinesAI's deep sync is part of why teams choose it. Plan the number consolidation first, then layer the team workflow on top.
