What the score and shapes mean

Score = public maintenance, adoption and docs signals, as a percentile of 52 tools. Nobody here tested these hands-on. Shapes are the separate safety label: No issues found, No dependencies scanned, Caution.

What it does for you

Small businesses and product teams with repeat support questions and written documentation.

  • Answer common questions from your help centre
  • Collect details (order number, version) before escalating
  • Draft replies for agents to approve
  • Route tickets by topic and urgency
  • Show which document an answer came from
More about this job

A support bot works best when it answers only from your documentation and escalates otherwise. Platforms that combine a knowledge base with workflows and chat make this achievable without building everything yourself.

Workflow in 5 steps

  1. Collect your real support questions and the pages that answer them.
  2. Load the documentation into the platform or retrieval engine and test the 30 most common questions.
  3. Set the rule: answer only from sources, otherwise hand over.
  4. Launch to a small share of traffic with a visible "talk to a human" option.
  5. Review conversations weekly and fix gaps in the documentation.

Watch out for

  • AI output can be fluent and wrong.
  • Prompts sent to a hosted model leave your machine.
  • Treat AI changes like a pull request from a new colleague: read the diff, run the tests and keep a human sign-off before anything ships.
  • A wrong confident answer about refunds or safety is worse than no bot.
  • Licence to check before commercial use: n8n (Sustainable Use License), Dify (Dify Open Source License (modified Apache-2.0)).

Why these warnings?
  • AI output can be fluent and wrong. Check facts, code and citations yourself before you rely on them or publish them.
  • Prompts sent to a hosted model leave your machine. For confidential material use a local model or check the provider's data terms first.
  • Treat AI changes like a pull request from a new colleague: read the diff, run the tests and keep a human sign-off before anything ships.
  • A wrong confident answer about refunds or safety is worse than no bot. Test refusals as carefully as answers.
