Friction gate for doomscrolling on X/Reddit/HN
A browser extension that forces a short cognitive-load task (math, typed intention) before opening known doomscroll sites, for people who already tried quitting cold.
- the deterministic verdict came out negative — the evidence argued against building it (VERDICT_KILL)
- the outcome the product promises is not controlled by the product (CONTROLLABILITY_GATE_FAILED)

Turn this into a build spec
One Universal Core, then the exact file layout your platform expects — CLAUDE.md, .cursor/rules, a Lovable knowledge base, a Bolt prompt under its 400-word ceiling. Evidence travels with it.

Reading an open idea needs nothing. Generating a spec from it calls a model and costs real money, so it needs an account and credits — the cost is shown before you spend anything.

Supporting evidence2
A user explicitly describes wanting a tool to enforce cognitive breaks before accessing distracting content, and describes doing math as a self-imposed friction mechanism.
A separate user quit a major platform entirely because the feed served unrequested, repetitive content, showing willingness to abandon incumbents rather than tolerate the problem.
Falsifying evidence3
The founder's stated cause of death is retention collapse because users disable the extension when inconvenienced, and uninstalling is one click. This is not a falsifiable risk you can design around—it's the central mechanism failing. If the friction gate works (blocks access), users remove it; if it doesn't work (easy to bypass), it has no effect.
The signal set shows people articulating the problem (S-1869, S-2256) but contains zero evidence of anyone paying for or sustaining use of a solution. The one paid app mentioned (S-7) is presented as a personal build with no retention data, and Instagram itself is listed as a product in this space (P-1320) despite being the thing users want to escape.
Free browser extensions and native platform settings (Screen Time, Digital Wellbeing) already offer blocking, friction, and time limits at zero cost. The stated cause of death acknowledges this directly: 'free blockers already solve 80% of the problem for zero cost,' leaving no clear wedge for a paid product without the cross-platform or social features the evidence never mentions anyone wanting.
Most likely cause of death
The founder builds a friction-gate extension, gets a wave of interest from people who self-identify as doomscrollers, and then watches retention collapse within weeks because users disable the extension the first time they're mildly inconvenienced (uninstalling is one click) and because free blockers already solve 80% of the problem for zero cost. Defensibility would need to come from something incumbents can't easily copy — e.g., cross-platform intention-tracking or social accountability — not from the friction mechanic itself, which any browser extension or the platforms' own settings menu can replicate.
Demand ladder
A complaint is not a customer. Weighted ×1 / ×3 / ×8 / ×15.
Counted from clustered complaint signals. No candidate-relative commercial check was applied, so no revenue is attributed to this idea.
Verified revenue: not established for this idea. No record ties a revenue figure to a product selling what this would sell.

Problem evidence
Who feels this, how often, and why what they use today does not fix it.
- Who feels it
- Technically literate adults who read Hacker News, X, Reddit and news sites reflexively on a laptop, have already noticed the habit degrading something they care about (deep work, math practice, sleep), and have already tried quitting by willpower or by deleting an account. Evidence is limited to this population — all five signals come from Hacker News.
- How often
- Daily, in short involuntary bursts. The trigger point is the reflex tab-open between tasks; the pain is reported as accumulated ('I spend too much time') rather than as a single acute incident, which matters because there is no invoice-shaped moment that forces a purchase.
- Why current fixes fail
- The two fixes people describe both fail at the same moment: the moment of reflex. Hard blockers (site blockers, app timers) are binary — they either block a site the user genuinely needs for work several times a day, so the user disables them by mid-morning, or they are set loosely enough to be irrelevant. Quitting a platform outright works but costs the whole platform: one signal reports leaving Instagram entirely because the feed was unusable, i.e. the fix is amputation, not moderation. Neither addresses the specific gap the doomscroll signal names: wanting a deliberate pause between reflex and feed while keeping access. There is no evidence in this block that anyone is dissatisfied enough with the free blockers to switch — counter-evidence explicitly notes the complaints target the platforms, not the tools.
At least one user explicitly wants a cognitive-break mechanism before reaching distracting sites, framed exactly as this idea: doomscrolling X/Reddit/HN while losing the ability to do real math.
The desire to reduce feed consumption without leaving the platform appears repeatedly: users object to repetitive, algorithmically injected content they did not ask for, and want it filtered rather than the platform abandoned.
Some users solve the problem by full withdrawal instead of by tooling — one stopped using Instagram outright, another population is described as buying single-purpose devices to escape smartphones. Withdrawal is a free substitute for any product in this category.
There is exactly one datapoint of money changing hands anywhere near this problem: a developer built a $5 app for their own phone addiction. It is a one-time $5 price set by a self-treating builder, not a validated market price, and no sales figures are given.
Free, adjacent tools are already in these users' vocabulary — Scrolless Feed Blocker is named by a user, and site blockers/app timers such as StayFocusd are on file as trivial free alternatives. Nobody in this block complains about them.
The whole cluster rests on three signals from a single source (Hacker News), with a weighted demand score of 7 and no 30-day movement. This is not evidence of a market; it is evidence that a handful of engineers described the feeling out loud.
The wedge is structurally exposed: Reddit, Instagram and X own the feed and can ship native 'take a break', reduced-repetition or screen-time settings, and browser vendors can ship site-level limits, in either case removing the reason to install anything.
No signal in this block shows anyone paying for friction specifically — no subscription, no trial, no price discussion beyond the $5 app.
