Pros & Cons
GoSearch
Pros
- The Free plan and the $20 per user Pro plan let small teams start without talking to sales.
- More than 100 connectors, including MCP and custom ones, and search results respect existing app permissions.
- Agents and workflows can be built without code and run inside Slack and Teams.
- The vendor states SOC 2 Type II, GDPR, CCPA and HIPAA compliance, with zero data retention.
- G2 reviewers praise its fast, accurate search and quick setup.
Cons
- SSO/SAML, audit logs, the API and BYO cloud are only available on the custom-priced Enterprise plan.
- The Free plan's limit of 10 searches and 3 AI queries per day is too low for real evaluation by a whole team.
- There are few independent reviews: about 21 on G2 and very few on Capterra.
- Reviewers mention limited filters and customization, and occasional slowness or bugs.
- Analysts say its analytics and connector depth for niche systems trail Glean-class suites.
Sierra
Pros
- Outcome-based billing means customers usually pay only for resolved conversations or other agreed results, not for each seat.
- Three build options cover both CX teams and engineers: the no-code Agent Studio, the code-first Agent SDK, and Ghostwriter for building agents from SOPs.
- One agent runs across chat, voice, SMS, WhatsApp, email and ChatGPT, keeping context between channels.
- Its list of compliance attestations is broad, covering SOC 2, ISO 27001, ISO 42001, HIPAA, PCI DSS and FedRAMP.
- It has a strong roster of enterprise customers, including SiriusXM, ADT, Rocket Mortgage and SoFi.
Cons
- There is no public pricing, and competitor estimates put annual contracts at about $150,000 or more.
- There is no self-serve or trial tier, so small teams cannot try it on their own.
- Implementation is largely vendor-led, which can make customers depend on Sierra's team for changes.
- There are few public reviews (7 on Gartner Peer Insights) to verify claims against.
- Some reviewers say voice quality still falls short of human level, and that complex telephony setups depend on how far the integration goes.
