Koji vs Lookback: AI-Native Research vs Live Moderated Sessions (2026)

Choosing between Koji and Lookback? Here is an honest breakdown to help you decide.

Both tools serve user researchers who want to learn from real customers. But they take fundamentally different approaches: Lookback is built around live, human-moderated sessions with powerful observer tools; Koji is an AI-native platform where the AI conducts the interview, analyzes results, and generates insights — all without a moderator in the room.

Neither is universally better. The right choice depends on your research goals, team size, and how much moderator bandwidth your team actually has.

Where Koji Shines

Scale Without a Research Team

Koji's core strength is eliminating the bottleneck of human moderation. Once your study is configured, the AI interviewer conducts all conversations autonomously — whether that is 10 interviews or 1,000. There is no scheduling, no session facilitation, and no post-session transcription to manage.

According to the Maze Future of User Research 2026 report, 66% of teams experienced an increase in research demand last year — but headcount and tooling have not kept pace. Koji is built specifically for this gap: enabling teams to run more research without hiring more researchers.

Cross-Session Synthesis at Speed

Where Lookback's Eureka AI summarizes individual sessions, Koji analyzes across all interviews simultaneously — surfacing themes, sentiment patterns, and insight clusters from the full dataset. Manual thematic analysis of a 20-interview study typically consumes 40–60 hours of analyst time. Koji compresses this to minutes.

According to a 2023 UserInterviews ROI report, traditional agencies charge $15,000–$27,000 for a moderate qualitative study and take 4–8 weeks to deliver. Koji's model is designed to deliver comparable depth in hours, not weeks.

Voice Conversations That Feel Natural

Koji's AI interviewer conducts natural voice conversations in real time. Participants respond the way they would to a real person — not by filling out a form. This produces richer qualitative data than surveys while requiring zero moderator time.

Always-On Research Cadence

Teresa Torres, author of Continuous Discovery Habits, argues that the single highest-leverage research habit is one customer interview per week, every week. Koji makes this achievable without dedicated researcher bandwidth — you set up your study once and keep gathering insights continuously.

Where Lookback Shines

Live Moderated Sessions

Lookback's Observer Lobby is genuinely excellent. Stakeholders and teammates join a virtual room to watch sessions in real time, leaving time-stamped comments without disrupting the participant. For research where seeing a participant's facial expressions, hesitations, or emotional reactions matters — new product concepts, sensitive topics, complex workflows — live moderated sessions with Lookback are hard to beat.

Stakeholder Alignment

One of the underappreciated challenges in user research is getting executives and product managers to actually engage with findings. Lookback's observer experience solves this problem directly: when stakeholders watch real users struggle with a product in real time, the insight lands differently than a slide deck ever could.

Cross-Platform Session Capture

Lookback supports moderated and unmoderated sessions across desktop, iOS, and Android, making it a practical choice for teams testing mobile apps in native environments. The platform was rebuilt in 2024 with significantly improved video reliability and support for sessions up to four hours.

Eureka AI Assistance

Lookback expanded its Eureka AI in 2025 with three new workflows — Stakeholder Interviews, Stakeholder Goals, and Automatic Surfacing of Findings. The Insight Button lets researchers capture key moments during live sessions with a single click, which Eureka then annotates automatically.

Where Lookback Falls Short

Analysis requires external tools. Lookback's Eureka provides per-session summaries, but meaningful cross-study analysis still requires researchers to export data into Dovetail, Notion, or spreadsheets. "Lookback plus Dovetail" is a widely cited pairing in the market — which means two subscriptions, two workflows, and added complexity.

Manual moderation is a bottleneck. Every moderated session requires a researcher to schedule, facilitate, and actively moderate. For teams without dedicated research staff, this constraint severely limits how much research they can run. According to the UserInterviews State of User Research 2025, 80% of researchers now use AI tools — primarily to reduce the operational overhead of tasks like transcription and synthesis.

Chrome-only participant experience. Lookback requires participants to use the Chrome browser, creating friction and potential drop-off — particularly on mobile.

No quality assurance on session data. Lookback does not review session quality, so low-effort or disengaged participants may go undetected in your dataset.

No research repository. Unlike Dovetail or Condens, Lookback does not serve as a research repository. There is no cross-project search, hierarchical coding, or theme clustering across studies.

Best Choice For...

• Choose Koji if: You need to run interviews at scale, lack a dedicated research team, or want AI to conduct and analyze conversations without moderator involvement. Koji is ideal for continuous discovery, product feedback loops, and any scenario where speed and volume matter more than live observation.

• Choose Lookback if: You are running live moderated sessions where observation and stakeholder presence are critical — concept testing, sensitive user research, or exploratory studies where seeing participant reactions in real time is essential.

• Consider both if: Your team runs live moderated sessions for deep discovery (Lookback) while also needing to gather feedback at scale between projects (Koji). Many mature research teams use session capture tools and AI interview tools as complementary capabilities.

Pricing Comparison

| Plan | Koji | Lookback | |------|------|---------| | Free/Trial | 1 study, 5 interviews | 5 sessions, 60-day trial | | Entry tier | €99/mo | ~$25/mo (10 moderated sessions/year) | | Mid tier | Custom | ~$149/mo (100 sessions/year) | | Enterprise | Custom | Custom (unlimited) |

Important context: Lookback's Starter plan is nominally cheaper, but it includes only 10 moderated sessions per year — roughly one per month. Teams that want to practice continuous discovery at even a weekly cadence would need the Professional tier (~$149/mo), with additional sessions at ~$17.80 each. Koji's pricing model does not cap individual interview counts at higher tiers, making it more economical for high-volume research programs.

The Research Demand Gap

The UX research software market was valued at $245 million in 2024 and is projected to reach $720 million by 2033 — a 12.7% CAGR (Fortune Business Insights). Driving that growth: 58% of product professionals now use AI in their research workflows, up from 44% in 2024, according to the UserInterviews State of User Research 2025.

The tools that will win in this environment are the ones that reduce friction between "we need customer insight" and "we have customer insight." For live moderated research with stakeholder presence, Lookback reduces that friction. For async AI-moderated research at scale, Koji eliminates it entirely.

Frequently Asked Questions

Can I migrate research data from Lookback to Koji? Lookback exports session recordings, transcripts, and notes. Since Koji analyzes conversational interview data rather than video files, direct migration is not applicable — but insights from past Lookback studies can inform your Koji research brief and study design.

Does Koji replace Lookback for all use cases? No. Koji does not support live observer sessions or video-based moderated research. For studies where watching participants react in real time is essential, Lookback remains the better tool for those specific sessions.

Is Koji's AI as good as a human moderator? For most discovery, feedback, and validation research, Koji's AI interviewer produces insights comparable to human-moderated interviews — and significantly faster at scale. For highly sensitive or deeply exploratory research requiring improvised follow-up, human moderation still has advantages.

What is the biggest reason teams switch from Lookback to Koji? Most commonly: teams want to increase research velocity without increasing headcount. When the bottleneck is moderator availability and analysis time, Koji removes both constraints simultaneously.

Does Koji offer stakeholder observation like Lookback? Not in a live format. Koji's research reports and insight dashboards give stakeholders full visibility into findings — but there is no live observer lobby for watching sessions in real time.
