Tier comparison

Bridge ships five tiers. Every higher tier is a strict superset of the lower ones — no feature is removed when you upgrade.

One-sentence summaries

Free — a notes app with a graph that helps you see what you've been thinking about.
Discover — Free, plus an AI that connects related notes into themes for you.
Build — Discover, plus turn this idea into a plan in one tap.
Refine — Build, plus a co-pilot that edits your plans through chat, with your approval on every diff.
Refine LTD — Refine, forever, one payment.

Trials

The paid plans have no trial: the Free tier is how you try Bridge. Refine LTD is a one-time purchase and has no trial.

Where you can buy

Web (bridgedev.io) — every plan, including the Refine LTD, through Stripe Checkout. In-app purchases are not available.

A purchase becomes the same Bridge entitlement on every signed-in surface. Manage it at bridgedev.io.

An unpaid plan is fixed at bridgedev.io. While a web subscription is past due or unpaid, Manage plan opens bridgedev.io so you can fix the payment. Until then Bridge won't sell you a second plan, so you're never billed twice.

¹ Chat starts at Discover. Adding an API key on the Free tier does not unlock it — the Free tier reaches an AI model only through its 5 monthly free runs. ² The 5 free monthly runs exist on every tier, but on a paid plan with your own key they're irrelevant — your key covers classification and expansion with no cap. The free-runs badge hides once your own key handles classification on a paid plan. ³ You can add a key on the Free tier, but it isn't honored: you stay at 5 runs a month until you're on Discover or above.

Free runs: 5 a month, on Bridge

Every account gets 5 AI runs per month at Bridge's expense — no API key needed.

What one run does. It reads a single note and decides whether it's an idea worth developing or a reference to keep. If it's an idea, the run also writes its expansion — a short paragraph that draws out what you meant, so the note becomes searchable, connectable to related notes, and ready to turn into a plan later.

Reference notes use a run too, even though they don't get an expansion — the run is spent on reading and classifying the note either way.

Resets on the 1st of each month.
Needs a verified email — verify when prompted, or your notes wait. Once you verify, the waiting notes are classified straight away.
Long notes are truncated to the first 2,000 characters for a free run.
Failed runs aren't counted. Deleting a note while its free run is still running gives the run back too.
Free runs can be paused. When they are, the app and the web demo say so, and no run is used. Paused notes are classified automatically when runs resume.
Runs out? On Free, a note captured after the cap says you're out of free runs and offers See plans; it waits for the reset. On a paid plan without your own key, the note asks you to add a key in AI & Models instead; add one and tap Retry, and it's classified on your key.
Constellations aren't included. Free runs cover classification and expansion; the semantic clustering that forms constellations starts at Discover.

You can also try a note without installing anything — the live demo on the web runs the same classify-and-expand against your account.

BYOAPI: what your subscription buys

Past the free runs, Bridge's subscription is an access fee for the workspace — not an AI markup. You supply your own API key from Anthropic, Gemini, or OpenAI. AI charges go directly to your provider account at their standard rates. No middleman markup, no surprise bills from Bridge.

A key is honored on a paid plan (Discover and above), where it gives unlimited classification and expansion at your provider's cost. On the Free tier a key isn't honored for those features — the 5-run cap still applies — so the Free tier stays genuinely free: your only cost is your time.

Bridge is one entitlement

If you buy Refine on web and sign into the mobile app, you get Refine on mobile. The entitlement follows your account; billing stays at bridgedev.io, where you manage the purchase.
