Luum vs Greenline
Greenline asks you to enter your own data, deliberately. Luum connects read-only to your brokerages. Both are Canadian; the difference is how data arrives.
Last updated September 11, 2026 · 8 min read
Greenline and Luum are both built for Canadian self-directed investors, both consolidate accounts a brokerage cannot show you together, and both are recent enough that you should read either company's own comparison page with the appropriate suspicion. This one is written by Luum.
The honest headline is that they disagree about one thing, and it is not a feature. It is how your data should get into the tool at all.
The short version
Greenline fits better if you would rather not connect anything to your brokerage, you want your portfolio on your phone, and a clean read on allocation, fees and returns is what you are after.
Luum fits better if you want the accounts to keep themselves current without you re-uploading anything, you need adjusted cost base tracked as one pool across accounts and years, and you want targets you set and drift measured against them.
The real difference: how the data arrives
Greenline does not connect to brokerages, and says so as a design position rather than a gap, its site puts it as "You enter your own data. That's on purpose." You upload a statement PDF, drop in a spreadsheet, type holdings in, or paste a screenshot. Nothing of yours ever authenticates against your institution.
Luum takes the other side of the same argument. It connects read-only through Snaptrade: you sign in on your own institution's page, Luum never sees your credentials, and no order path exists in the product at all. CSV import and manual entry are there too, for the accounts no integration reaches.
Neither position is wrong, and the trade is real. Manual entry means nothing to breach and nothing to revoke; it also means your portfolio is only as current as the last time you sat down to update it, and every partial sale and reinvested distribution is a line you have to remember to enter. A read-only connection means the history arrives complete and stays current; it also means there is a connection, which is a thing some people simply do not want. If you are firmly in one camp, that decides this comparison before any feature does.
What Greenline does well
Greenline is good at the thing it set out to do. It brings registered and non-registered accounts into one dashboard, reports both time-weighted and money-weighted returns, breaks your holdings down by sector, region and asset class, and digs the fees out of the funds you hold to show what they cost in real money. It tracks dividends, including what is coming. It ships iOS and Android apps, and it is free while it is in beta.
Two of those are things Luum does not have today: Luum is web-only, with no native mobile app, and Luum is a paid product. If either is decisive for you, it is decisive, and no amount of the rest of this page changes it.
What Luum does well
Luum's centre is the loop between the plan you wrote and the portfolio you actually hold. You set targets, by asset class, region and sector, not only by ticker, and Luum tracks drift against them continuously across every account, then computes the trades that would move you back toward target. You place them yourself, at your brokerage. The arithmetic is the tool's job and the decision stays yours.
It looks through your ETFs to what they actually hold, so two funds owning the same companies cannot hide a concentration behind two different names, and it flags a position that has quietly grown past your comfort level.
And it keeps the record that is hardest to reconstruct later: adjusted cost base, pooled with the average-cost method across accounts and across years of partial sales. The CRA pools identical property per taxpayer rather than per account, so this is a number no single brokerage is positioned to get right for you. See adjusted cost base, explained for why. Luum's ACB figures are educational, depend on your transaction history being complete, and do not apply the superficial loss rule; verify them before you file.
Beyond the record, Luum measures whether the plan is working. Your return is compared against an index funded with your real contributions on the dates you made them, which is the comparison that does not flatter you for adding money into a rising market, and the return of your holdings is kept separate from the return your money earned.
On the Wealth tier the Strategy page goes further: blended risk from beta, volatility and maximum drawdown, concentration scored with the Herfindahl-Hirschman Index across asset class, sector, geography and individual holding, each fund's real management expense ratio compounded over ten, twenty and thirty years, pairwise overlap between two funds you own, and your home-country bias measured against the Canada weight in a global index. Its Monte Carlo projection runs ten thousand simulated paths from your actual allocation, on the capital market assumptions published annually by FP Canada and the Institute of Financial Planning for long-horizon projections, and says whether you are on track against your goal and what the gap is in today's dollars. Your cost, concentration and return are set against anonymised aggregates of users with similar risk profiles, goals and horizons.
The rest of the Canadian record sits alongside it: realised gains across every reportable account together with registered accounts excluded, the year's dispositions exportable as a T5008-style CSV, and, on the Investor tier and above, TFSA and RRSP contribution room drawn down from the figure on your notice of assessment. Ticker Scores rank what you hold on five measured dimensions nightly, watchlists carry optional price alerts, and the Explore tab covers exchange-wide movers, 52-week highs and lows across the TSX, NYSE and NASDAQ, and an IPO calendar.
As of September 8, 2026, Greenline's own site describes realised gains and losses but does not describe adjusted cost base tracking or Canadian tax reporting. That is a statement about what their site says on that date, not a claim about what their product can do, if this matters to your decision, check it yourself before you rely on it.

Where this leaves you
If you would rather type your own holdings in than connect anything, and a phone is where you want them, that is a real preference and manual entry is what Greenline is built around. Luum accepts manual entry too, and it is not what the product is organised for.
If what you keep running into is that nobody can tell you your real cost base across two brokerages, or that your actual allocation has drifted somewhere away from the plan you wrote down and you cannot see where, that is the problem Luum was built around. Start with the product tour, or read how Luum tracks adjusted cost base if the tax record is the part you care about.
Common questions
Does Greenline connect to brokerages?
No, and deliberately not. It asks you to enter your own holdings, which is a design choice rather than a gap: nothing is shared with an aggregator and nothing breaks when a brokerage changes its login flow. The cost is that you keep it current by hand.
Does Luum require manual entry?
No, though it supports it. Connections are read-only and bring holdings in automatically, and manual entry exists for brokerages that are not supported. The trade against Greenline is convenience for a connection you have to trust.
Are both of these Canadian?
Yes, both are built for Canadian investors, which is why the comparison is about how data arrives rather than about market coverage or tax jurisdiction.
