The short version

  • Only Seamless.AI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Assembled the published per-agent rate is not the whole bill, because a separate platform fee sits on top and is not published, so the headline 25 USD figure understates the real cost and you still need a quote to know the total.; Seamless.AI pro and Enterprise pricing is not published and requires contacting sales.
  • They diverge on capability: Assembled covers Volume forecasting, Seamless.AI covers Contact search.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Assembled

  • The published per-agent rate is not the whole bill, because a separate platform fee sits on top and is not published, so the headline 25 USD figure understates the real cost and you still need a quote to know the total.
  • Pricing AI Agents per resolved conversation while pricing workforce management per seat means the two products pull in opposite directions financially: successful deflection shrinks the seat count you are billed for and grows the consumption charge, making year-two budgeting unpredictable.
  • Long-range capacity planning and what-if scenario modelling are thinner than in NICE or Verint, so organisations doing annual headcount planning across multiple sites often end up exporting to a spreadsheet anyway.
  • There is no quality management or agent evaluation module, so a support organisation that wants WFM and QA from one vendor has to buy a second tool and reconcile two sets of agent records.
  • The product assumes a modern ticketing system as the source of truth; teams running a legacy ACD or a homegrown queue face custom integration work that the standard connectors do not cover, and forecast accuracy suffers until that data is clean.
  • There is no native mobile application, so agents check schedules, request time off and swap shifts through a mobile browser, which is a persistent friction point for hourly and contact centre workforces who do not sit at a desk.

Seamless.AI

  • Pro and Enterprise pricing is not published and requires contacting sales.
  • Free plan is limited to just 50 credits and a single user.
  • Data accuracy for contact details can vary and requires verification before outreach.
  • Credit-based usage model means heavy prospecting can exhaust allotments quickly.

Answered from the vendors’ own pages

Assembled: Does Assembled publish its real total cost?

It publishes per-agent tier rates of 25, 45 and 75 USD per month but adds an unpublished platform fee, so budget for the seat rate plus a fixed annual platform charge that you must ask for.

Seamless.AI: Is there a free plan, and what are its limits?

Yes, the Free plan includes 1 user and 50 credits, with access to email and cell phone search, real-time search, and API access.

Source
Assembled: Can I buy the AI agents without buying workforce management?

Yes. Assembled sells WFM, AI Copilot and AI Agents as separately purchasable products, and AI Agents are billed at 0.65 USD per resolved conversation rather than per seat.

Seamless.AI: How is usage metered on Seamless.AI?

Seamless.AI uses a credit system where credits are consumed to research contact details; paid Pro plans start with larger annual credit packages than the Free plan.

Source
Assembled: Is it suitable for a voice-first call centre?

Less so. The forecasting and scheduling are built around omnichannel ticketing volume, and voice-heavy operations running a legacy ACD will find the integration and intraday voice controls weaker than a traditional WFM suite.

Seamless.AI: Does Seamless.AI have an API?

Yes, API access is included even on the Free plan, alongside export and integration capabilities on paid plans.

Source
Assembled: How long does implementation take?

Assembled states typically one month or less, which is realistic when your helpdesk is Zendesk or Salesforce and historical data is clean.
