Koyfin has long been the closest thing retail investors have to a Bloomberg Terminal at a fraction of the cost. Their recent addition of AI-generated earnings call summaries is either the most useful feature they’ve shipped in two years, or another AI gimmick. We spent three weeks finding out.
What the Feature Does
When a company reports earnings, Koyfin now generates a structured AI summary of the earnings call transcript. The summary breaks down into four sections:
- Financial highlights — revenue, EPS, margins vs. expectations
- Management commentary — what the CEO/CFO emphasized
- Analyst questions — key themes that came up in the Q&A
- Guidance and outlook — forward-looking statements
The summaries appear automatically within about 2 hours of the call ending.
The Test: 20 TSX Companies
We ran the feature across 20 TSX-listed companies spanning financials, energy, and tech over Q4 2025 reporting season. Companies included TD, Suncor, Shopify, BCE, CNR, and 15 others.
Results:
| Category | Accuracy | Useful? |
|---|---|---|
| Financial figures | 97% match to transcript | Yes |
| Management tone/emphasis | 85% aligned | Mostly yes |
| Analyst question themes | 78% complete | Usually yes |
| Guidance extraction | 91% accurate | Yes |
The one consistent gap: when management used vague language on guidance (“we remain cautiously optimistic”), the AI sometimes over-interpreted this as a positive signal. Read the guidance section skeptically.
Canadian Coverage
This was our main concern going in. Koyfin’s strength has historically been US-listed stocks, and TSX coverage has been thin.
The good news: earnings call transcripts for all TSX companies in the S&P/TSX 60 are now covered. For smaller-cap TSX stocks (sub-$2B market cap), coverage drops to about 60%. If you’re mainly invested in large-cap Canadian names, you’re fine.
Workflow Integration
The fastest workflow we found:
- Open Koyfin the evening after a company you own reports
- Read the AI summary (2 minutes) — decide if anything needs deeper investigation
- If yes: jump to the specific transcript section flagged
- If no: move on
This replaced a previous workflow of skimming 45-60 page transcripts and listening to 90-minute calls for a handful of key details. Time saved per earnings call: 30–45 minutes.
Pricing
Koyfin’s AI features are available on the Pro plan ($49 USD/mo) and above. The standard plan does not include them.

Bottom Line
For anyone who actively reads earnings call transcripts, this feature pays for itself in time saved within the first reporting season. The TSX coverage is now good enough to be useful for Canadian-focused portfolios.
The accuracy on financial figures is high. Where it falls short — reading management tone and interpreting vague guidance — is exactly where human judgment still matters. Use it as a first pass, not a replacement for actually reading the calls on your highest-conviction positions.
