Legislative tracking software for founders: four picks compared
Most startups face a handful of bills, not hundreds. Here is how AyeWatch, BillTrack50, Plural and Quorum compare on coverage, price and who each one suits.
Legislative tracking software follows bills through Congress or a state legislature and tells you when they move. For most founders the best pick is the lightest tool that covers the bills you actually face, which is why we put AyeWatch first: it watches the bill pages you name and sends a short summary when something changes, and the heavier platforms only pay off once a team tracks many bills at once.
Start with your exposure, not the feature list
A seed-stage company rarely has a government affairs team. It has one bill in one committee that could change its pricing, a state privacy proposal, or a licensing rule in the two states where it hires. Buying a platform built for a lobbying shop to watch three bills is like buying an ERP to send invoices.
Three questions sort the options:
- How many bills? Under a dozen is a watch list. Hundreds across states is a research job.
- How many people? One founder reading alerts needs different tooling from a team that assigns bills and records positions.
- Do you need to act, or just know? Grassroots campaigns, meeting logs and PAC work belong to full public affairs suites.
The four picks
| Tool | Best for | Coverage | Starting price (November 2026) |
|---|---|---|---|
| AyeWatch | A short list of bills and pages, filtered alerts | Any public bill page you add, plus topics | Free preview; paid plans from $9 a month |
| BillTrack50 | Searching and tracking by state | All 50 states, DC and Congress | Free search; tracking from $84 a month per state or Congress, paid monthly on an annual subscription |
| Plural | One analyst covering many states | Congress, all 50 states, DC and Puerto Rico | Essential at $59 a month for one seat |
| Quorum | Government affairs teams that also run advocacy | All 50 states and Congress | Demo; no price on the site |
1. AyeWatch
Paste a Congress.gov or state legislature bill page into AyeWatch and write the rule in plain words, such as "alert me when this bill gets a hearing or an amendment." It reads changes for meaning, so page clutter stays out of your feed, and a topic monitor can follow news about the same bill. Push and the feed come with every plan, while email, Slack, Discord and webhooks are on paid plans. It has no bill database of its own and does no advocacy work; it is the alert layer for the pages you care about.
2. BillTrack50
BillTrack50 offers free searching of current-session bills, and its paid tracking adds bill sheets, daily email alerts and a separate reminder for committee hearings in the next seven days, according to its pricing page. It also tracks regulations. Good when you want to search a state's whole session, not just follow known bills.
3. Plural
Plural, which took over the Open States project, sells legislative and regulatory tracking for government affairs teams. Its Essential plan covers unlimited bills with saved searches and email alerts for one person, without AI summaries; those start on the Professional plan at $5,000 a year.
4. Quorum
Quorum pairs bill tracking with hearing transcript search, stakeholder records, grassroots tools and PAC management. It is built for organizations where policy is a department, not a side task.
When free is enough
If you follow one federal bill, Congress.gov's own email alert costs nothing and only needs an account. Some states run free tools too: Texas Legislature Online's MyTLO sends email when a bill picks up significant actions. Use those until you are juggling logins.
For a founder watching a handful of bills across Congress and a couple of states, AyeWatch is the recommended pick: one feed, plain-English rules, and a summary instead of a raw diff. Move to Plural or Quorum when tracking turns into a team's full-time job. None of this is legal advice; your counsel still reads the text.
