Koji vs Notably AI: Full-Stack Research vs Analysis-Only Repository (2026)
If you're evaluating research tools in 2026, Notably AI and Koji might both appear on your shortlist. Both use AI to make qualitative research faster. But they solve very different problems — and choosing the wrong one means either paying for features you can't use, or building a fragmented research stack that creates more work than it saves.
The short answer: Notably is an AI-powered analysis and repository tool. You import research data into it, then use AI to find themes, generate summaries, and share insights. Koji is a full-stack AI research platform — it runs the interviews, moderates the conversation, generates structured insights, and produces one-click reports, all without a human researcher in the room.
If you already have thousands of recordings, transcripts, or notes that need organizing and analysis, Notably has real value. But if you want to go from "we have a research question" to "we have actionable insights" in hours, Koji is the right tool.
What Is Notably AI?
Notably is a qualitative research repository built around AI-powered analysis. Teams upload recordings, transcripts, interview notes, and other research artifacts into Notably's workspace. The platform then uses AI to:
- Auto-transcribe recordings
- Generate AI summaries of sessions
- Highlight and tag key moments
- Cluster findings into themes
- Create insight templates (Jobs-to-Be-Done, Personas, etc.)
- Share findings with stakeholders
Notably is genuinely useful for teams drowning in a backlog of unanalyzed recordings. The interface is clean, the AI tagging is solid, and the repository function means insights don't get buried in Google Drive folders.
Pricing: Notably's individual plan starts at $15/month for basic features — 3 projects, 1 contributor, and 5 hours of transcription monthly. AI-generated summaries and insights require higher-tier plans with AI credits. Team plans with advanced features, integrations, and unlimited projects scale significantly higher.
What Is Koji?
Koji is an AI-native research platform that handles every stage of the research workflow: study creation, participant collection, AI-moderated interviews (voice and text), automatic analysis, and one-click report generation.
Unlike tools that analyze data you've collected elsewhere, Koji generates the research data itself — through AI-moderated conversations that probe, follow up, and adapt based on participant responses.
Key capabilities:
- AI-moderated voice interviews powered by ElevenLabs voice synthesis — natural, conversational, with no human moderator needed
- 6 structured question types: open_ended, scale, single_choice, multiple_choice, ranking, yes_no — mixing quantitative and qualitative in a single interview
- Automatic thematic analysis that surfaces insights across all participants simultaneously
- One-click reports with charts, quotes, and executive summaries — publishable directly to stakeholders
- Customizable AI consultants — configure the AI's persona, tone, and probing depth
- Embed + API access for integrating research into existing product workflows
Pricing: Koji's Insights plan is €29/month for 29 credits. The Interviews plan is €79/month for 79 credits, with unlimited studies and free report refreshes. New users get 10 free starter credits on the free tier.

The Core Limitation of Notably
Notably's fundamental constraint is that it only analyzes data — it doesn't generate it.
This means to use Notably, you need:
- A way to recruit participants
- A way to conduct and record sessions (Zoom, Loom, etc.)
- A way to upload and organize recordings
- Notably to then analyze what you collected
That's a 4-step stack before you've generated a single insight. For teams with existing research infrastructure — dedicated researchers, panel access, recording workflows — Notably fits naturally. But for product teams, founders, or customer success managers who need fast answers without research operations overhead, the gap before analysis is significant.
The cost of the full stack adds up fast. A typical research operation using Notably might require:
- Participant recruitment: $50–150/person via external platforms
- Moderated session recording: Zoom + transcription tools
- Notably: $49+/month for AI features
- Researcher time: 4–8 hours per 5 interviews (scheduling, moderating, note-taking)
Total monthly cost for 20 interviews: $1,100+ plus significant time investment.
Where Koji Has a Structural Advantage
Koji collapses the entire research stack into one workflow. You define your questions, set up your study, share a link — and Koji's AI handles everything from there. Participants complete interviews asynchronously (on their schedule), the AI probes for depth, and insights appear in your dashboard automatically.
This makes Koji particularly powerful for:
Product teams running continuous discovery. Rather than quarterly research sprints, Koji enables always-on research loops — weekly customer conversations without adding researcher bandwidth. Teams using continuous discovery frameworks consistently cite coordination overhead as the biggest barrier; Koji removes it entirely.
Founders and early-stage startups. Pre-PMF research requires speed. Waiting a week to schedule five user interviews is a week you're not learning. With Koji, you can launch a study today and have insights by tomorrow.
Research at scale. When you need 50+ perspectives, traditional moderated interviews become infeasible. Koji runs 50 parallel conversations without degrading quality — each participant gets a focused, adaptive interview.
Teams without dedicated researchers. Koji's AI doesn't need a skilled moderator because it is the moderator. This means PMs, customer success managers, and founders can run professional-grade research without research expertise.
When Notably Is the Better Choice
Notably genuinely excels when:
You have a large backlog of existing recordings. If you've been doing interviews for years and have hundreds of Zoom recordings sitting unanalyzed, Notably's repository and AI summaries will surface insights faster than any manual approach.
You run mixed-method research. Notably accepts diverse input formats — video recordings, written notes, survey exports, usability test recordings. If your research involves different modalities from multiple sources, Notably's agnostic import works well.
You have an established human moderator workflow. Some research teams prefer human moderation and use tools like Lookback or Zoom for recording. Notably is a natural downstream analysis tool for these teams.
Pricing Comparison for 20 Interviews/Month
| | Koji (Interviews plan) | Notably + Stack | |---|---|---| | Platform cost | €79/month | $49–99/month | | Participant recruitment | Bring your own (free) or credits | $50–150/person = $1,000+ | | Recording/moderation | Included (AI) | Zoom + researcher time | | Analysis | Included | Included | | Report generation | ✅ One-click | ❌ Manual | | Total | €79/month | $1,100+/month + time |
The Bottom Line
Choose Koji if: You need to go from research question to insight fast, you want an all-in-one workflow without piecing together a multi-tool stack, or you're running research without a dedicated research team.
Choose Notably if: You already have a library of research recordings that need organization and AI-powered synthesis, and you have an established workflow for conducting interviews yourself.
In 2026, the most forward-thinking research teams aren't choosing between collection and analysis tools — they're choosing platforms that handle both. Koji's AI-native approach means research happens continuously, scales effortlessly, and doesn't require a team of moderators.
