Automates routine client replies flawlessly.
Saved our support team hours every single day.
Pricing is steep for small teams.
Inbox management is solid.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
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.
Email is never used to train models or stored on Serif's servers, learning is encrypted at rest, and the platform meets SOC 2 Type II, CASA Tier 2, HIPAA, and GDPR standards.
Serif builds AI agents that take over the repetitive but fiddly parts of running a business: collecting documents, answering routine questions, chasing paperwork, and keeping follow-ups on track. You point the platform at real work, it learns how your team handles it, and then it runs the task continuously. When an agent encounters something outside its instructions — an unusual request, a missing document, an ambiguous clause — it routes the job to the right person rather than guessing. The result is automation that reaches completion instead of stalling halfway through a multi-step process.
The platform organizes this around three stages: diagnose, train, and run. Diagnosis surfaces workflows worth automating, training teaches agents how your business operates, and running puts the work on autopilot. Typical deployments cover document collection and processing (requesting, reading, and verifying files until a job is complete), compliance intake and quoting, complex support, accounting and tax tasks, real estate closing files, law firm engagement letters and questionnaires, and insurance claims packet collection. Agents work 24/7 across email threads, shared inboxes, and document attachments.
Security is treated as a first-class requirement. Serif states that your email is never used to train models and never stored on its servers, that everything the platform learns is encrypted at rest, and that its practices are audited by a third party. It publishes SOC 2 Type II, CASA Tier 2, HIPAA, and GDPR compliance claims. The product also offers a standalone personal email assistant and a free inbox report as an entry point, with paid plans for teams that need shared inboxes and full automation.
Let agents chase agents, lenders, and clients for signatures and documents, verify the packet is complete, and only surface exceptions, saving hours per transaction.
Automate sending, collecting, and checking engagement letters and client questionnaires, keeping matters moving without manual follow-up.
Automatically request, track, and validate claims documents, following up until the file is complete and escalating ambiguous cases to staff.
Chase clients for missing tax documents, verify submissions against requirements, and answer repeat questions without staff time.
