Needle provides retrieval-augmented generation (RAG) tools that enable semantic search across your data, facilitating the development of AI agents and applications.
Use Needle with DialNexa when the call needs classification, extraction, generation, retrieval, summarization, visual understanding, or another AI-assisted step.

​
Where Needle fits in a DialNexa workflow

Needle should receive DialNexa output when the conversation affects a model run, extraction result, generated answer, transcript, classification, media analysis, or tool call. The handoff should explain what the caller asked for, what DialNexa learned, which record or object is affected, and who owns the next step.

Generate useful drafts

Create replies, notes, briefs, summaries, or tasks from the exact call outcome and approved context.

Extract structured details

Pull names, dates, products, addresses, invoice numbers, image labels, or requested actions into fields.

Keep humans in control

Send low-confidence, sensitive, or account-changing outputs to review instead of acting silently.

Classify call intent

Turn messy speech into intent, category, urgency, language, sentiment, and confidence fields.

​
What DialNexa should capture for Needle

  • Transcript, summary, language, speaker role, media or file link, intent, confidence, and sensitive-data flag
  • Knowledge source, prompt version, model ID, tool call, allowed action, and fallback path
  • Generated draft, extracted fields, recommended next step, review reason, and owner
  • Transcript link, recording link, DialNexa call ID, CRM link, ticket link, and output record URL
  • Risk flags for hallucination, missing source, private data, low confidence, or restricted action

High-value Needle workflows

For this workflow, DialNexa should send Needle a concise, action-ready handoff: matched caller, affected record, reason for the update, urgency, owner, next step, and links to call evidence.
DialNexa should capture the preferred time, timezone, owner, promise made, and contact channel before updating Needle. The receiving team should see exactly why the follow-up exists and what the caller expects next.
For this scenario, DialNexa should treat Needle as an escalation destination. Send the impact, urgency, affected customer or object, owner, and transcript link so the right team can act before the issue gets colder.

Use search collection before answering, routing, or creating follow-up. DialNexa should verify the lookup result against the caller and send low-confidence matches to a human queue.
Use create collection only when DialNexa has a matched caller, a clear destination object, and enough call context to justify opening a new AI workflow result. If the caller is unclear, route to review instead of creating noise.

Implementation notes

  • Use the DialNexa call ID as the idempotency key before running Needle actions.
  • Write a short operational summary into Needle and link to the full transcript or recording for audit.
  • Map required fields before launch: destination object, owner, status, urgency, next step, and record URL.
  • Create review paths for low-confidence matches, sensitive requests, high-value customers, and actions that change money, access, legal terms, or customer commitments.

FAQs

Use approved knowledge sources, cite source records, set fallback behavior, and route low-confidence answers to humans.
Yes, but drafts should use the actual call outcome, approved tone, and customer context. Sensitive messages should be reviewed.
Secrets, payment data, private HR or health details, and anything your policy forbids unless the tool and workflow are approved.
Store confidence and route missing or conflicting fields to review rather than silently updating downstream systems.
When source context is missing, confidence is low, the caller disputes the answer, or the next step changes money, access, or legal commitments.
Intent accuracy, extraction accuracy, fallback rate, review overrides, bad answers, and customer outcomes after AI-generated follow-up.
Only for low-risk workflows with clear confidence thresholds. Account changes, money, access, legal, and sensitive support cases need review.
Prompt version, source context, model or workflow ID, confidence, output, call ID, and reviewer when applicable.
