AI communication platform for sales and support teams
Automated agents that resolve calls, qualify leads and route callers 24/7, with escalation to a human when needed.
Power, dynamic, predictive and parallel dialing with local presence and smart reattempt rules to boost connect rates.
AI call summaries, transcription, sentiment analysis, agent assist and automatic call scoring for coaching at scale.
SMS, MMS, RCS and WhatsApp conversations with bulk sending, bots and a shared team inbox.
AI agents that run your email and document work
Agents read email threads, pull attachments, run lookups, apply your policies, and write replies automatically, covering tasks from routine answers to multi-step document chasing.
Serif requests paperwork, reads what comes back, checks it against what you actually need, and keeps following up until the file is complete — ideal for closings, claims, and intake packets.
When an agent is unsure how to proceed, it routes the job to the right person for review, so automation handles volume while judgment stays with your team.
Manage addresses like info@, support@, billing@, and closing@ from a shared inbox, with email management, autoresponders, and customer service agents built in.
