Curated AI Stack · Consultants, founders, and analysts turning messy inputs into client-ready briefs weekly
AI Research & Summarization Stack for Operators (2026)
Research stacks fail when you collect 40 tabs and ship nothing. You need one capture layer (Notion), one SERP-aware brief tool (Frase), one reasoning engine for synthesis (Claude), and optional listen-back (Speechify) for long PDFs. Budget lands at roughly $45–75/month: Claude Pro ($20), Notion Plus + AI (~$10), Frase Solo (~$15–45), Speechify free tier until you binge-listen daily. No Perplexity slot here — we only map tools in our vetted catalog.

Stack Operator Reliability Score
Composite from core tools only — supplementary picks do not dilute the score. Your stack fails on the weakest glue, not the average.
Stack score = 0.60 × mean(core tool scores) + 0.40 × min(core tool score). Supplementary tools are listed but do not dilute the composite — your stack fails on the weakest core glue.

How we curated this stack
This stack pairs 3 core and 2 supplementary tools around one weekly workflow. Tools in curated stacks are evidence-checked on a weekly schedule: pricing is read from the vendor page and compared with the catalog band, public user reports from the last 90 days are collected with sources, and a person reviews the result before it is published. The check date and sources sit under each tool above; job-in-stack copy is editorial, not a hands-on test claim.
