If this is useful, keep it alive.

What does it cost to run this site, and how can you help? This page shows the bill. Bitinforming is one person, one terminal, and a stack of API bills. Every daily brief costs roughly $3 in API calls: Claude for summarization and narration, plus historical price lookups and audio synthesis. The site is free, ad-free, and will stay that way. If a brief saved you research time, or the strategy receipts convinced you of something, the buttons below keep this going.

One daily brief

Covers a single morning's API spend: summarization, narration, price fetches, the lot.

$30

One month of compute

Funds an entire month of daily briefs. The most common useful contribution.

★ Founder tier

$300

A quarter

90 days of daily intelligence, audio narration, and historical backtests. Buys real runway.

$3,000

A year

365 days of operation. If this site is your daily research tool, this is the honest price.

Where the project stands

These numbers load live from the same files the strategy and track record pages use, good and bad alike.

What the money actually pays for

Every dollar goes to one of these five line items.

Claude API. Every brief is summarized into plain English and narrated into a 2-minute audio briefing. Largest single line item.
yfinance / price data. Around 50 ticker lookups per day plus 1-year historical bars for the track record build. Free today, but I'm rate-limited and will eventually need a paid feed.
Firebase Hosting + Firestore. Small but real. Subscribers, archive, search index, daily JSON exports.
Patent + arXiv API calls. The actual signal source. Free APIs today but heavy traffic budgets.
My time. Half a day per week of operator effort to tune the model, watch for bugs, and write the brief. Tips here pay for the next round of feature work.

Or just stay on the list, free.

Honest answers

The questions readers actually ask, answered straight.

Is this an investment service?: No. Bitinforming publishes general commentary from public data, not personalized financial advice. The site does make calls, with the reasons printed, but every call goes to every reader at once and the operator knows nothing about your situation. The strategy page is a model portfolio: hypothetical, no positions actually held. The track record exists to be honest about whether the calls work (they sometimes do, sometimes don't). What you do with your money is your business.
What do I get for donating?: Truthfully: gratitude and the warm fuzzy of keeping a one-person project alive. There's no paywall, no premium tier, no gated content. Everything is free for everyone. If/when there's a paid email tier in the future, anyone who's tipped will get a generous discount, but I won't promise specifics I'd have to walk back.
Why no paywall?: Paywalls kill compounding audience growth, and I'd rather have 10,000 free readers than 200 paying ones at this stage. Tip jar instead. The economics work if a small fraction of regular readers throw $30 once a year.
Can I sponsor a brief?: Once readership is real, yes: a small "this issue brought to you by ___" line at the bottom of the daily brief is a clean way to underwrite a day. Use the contact button below if interested.
How do I get in touch?: Questions, sponsorship, feedback, or data-deletion requests: email the operator. We keep the address behind a button (instead of printing it) so spam bots can't harvest it:
Where does the data come from?: arXiv (computer science + AI listings), Google Patents (newly published applications), Google Trends (search-volume context), and yfinance (price history). Every step from raw feeds to tickers to impact scores to model picks is defined in code. I'll publish the repo publicly once a few security issues are scrubbed.
Does the strategy beat the market?: The honest answer changes with the market, so this line is computed from the latest data every time the page loads. The current numbers are on the strategy page. The sample is small enough that this could reverse next month, which is exactly why the track record page exists: to keep the numbers honest as they evolve. The full receipts are here.
